1. Dry cargo trades
1.1. Dry bulk carriers
Dry bulk carriers, the workhorses of the sea, carry out the essential transport of
the commodities without which our modern society would not be able to function. The
ships and their crews, together with the companies that operate them, do not enjoy the
glamour attached to other sectors of the industry more in the public eye; the bulk
shipping sector does, however, provide a highly cost-effective service for which proper
recognition is due.
The bulk cargo business is, like most other shipping sectors, subjected to
variable demand and supply with the entailing fluctuations in freight rates. During the
first decade of the 21st century, the business experienced peaks never seen before. The
boom was mainly driven by the China's unsaturated craving for iron ore which created
positive ripples all the way down the bulk carrier industry. However, no peak last forever
and here at the beginning of the second decade of the 21st century the world is suffering
under the credit crunch albeit fortunately with some optimism picking up.
In 1993 the bulk carrier fleet consisted of approximately 5000 ships. In the
beginning of 2010 the number of bulk carriers was close to 7500, with another almost
3200 new buildings expected to enter the market during the coming years. Not only is
the number of ships growing, today's bulk carriers are generally significantly larger than
their predecessors.
The shipping industry in general was significant increase in the number of ships
in the last years, which was giving rise to some concern about proper manning with
qualified seafarers.
1.2. Dry cargo trades: major and minor dry bulks and other dry cargo
In 2011, the momentum was maintained for dry cargo trade, which increased by
a firm 5.6 per cent, taking the total to nearly 6 billion tons. Dry bulk cargo, including the
five major commodities (iron ore, coal, grain, bauxite/alumina and phosphate rock) and
minor bulks (agribulks, fertilizers, metals, minerals, steel and forest products) increased
by 5.6 per cent, down from the 12.3 per cent increase recorded in 2010. The total
volume of dry bulk trade amounted to 3.7 billion tons in 2011.

a) Major dry bulks: iron ore, coal, grain, bauxite/ alumina and phosphate rock
In 2011, the five major dry bulks accounted
for approximately 42 per cent of total dry
cargo, driven by iron ore volumes, which
accounted for the largest share (42.5 per
cent), followed by coal (38.1 per cent), grain
(14 per cent), bauxite/alumina (4.4 per cent)
and phosphate rock (1.1 percent).
Growth in the five major bulks
remained closely linked to steel production,
growing infrastructure development needs
of emerging developing countries,
urbanization and the evolution of the global
manufacturing base. World consumption
and production of steel, a key product
supplier to many industries, continued to
expand in 2011 despite prevailing global
economic uncertainties and volatilities. In
2011, world steel consumption grew by 6.5
per cent, down from 15.1 per cent in 2010.
The deceleration reflects the overall
weakness of the world economy and the
slight slowdown in the economic expansion
of China.
Table 1. Major dry bulks and steel: main
producers, users, exporters and importers, 2011 (Market shares in
percentages)
With most of Chinese steel demand being driven by expenditure on investment and
construction, the country's steel consumption grew by 8.9 per cent in 2011, a slower
pace than in 2010.
Other emerging developing economies such as India, Brazil, the Republic of Korea
and Turkey, which have featured among the top 10 steel producers for the past 40
years, also increased output.
b) Dry cargo: minor bulks In line with developments in the world economy and the deceleration of growth
5
5
since the third quarter of 2011, growth in minor bulks trade decelerated to 6.1 per cent.
Global volumes reached 1.2 billion tons, a level surpassing the pre-crisis peak of 1.1
billion tons achieved in 2007. Exports of metals and minerals recorded the second
fastest growth (7.4 per cent) after agribulks (8.6 per cent), while manufactures
expanded by 5.6 per cent and fertilizers (excluding phosphate rock) grew by 4.3 per
cent. The only contraction recorded was in sugar volumes, which fell by 7.4 per cent,
following a growth of 11.9 per cent in 2010. Looking to the future, trade in minor bulks is
projected to expand further in 2012, albeit at a slower rate, reflecting in part the
weakening in the world economy and the slowdown in steel production activity, an
important source of demand for a number of minor bulks.
2. Solid bulk cargo and type of cargoes
2.1. Solid bulk cargo
Solid bulk cargo means any cargo, other than liquid or gas, consisting of a
combination of particles, granules or any larger pieces of material generally uniform in
composition, which is loaded directly into the cargo spaces of a ship without any
intermediate form of containment.
When it is assessed that the solid bulk cargo proposed for carriage may present
hazards as those defined by group A or B of IMSBC Code1, advice is to be sought from
the competent authorities of the port of unloading and of the flag state. The three
competent authorities will set the preliminary suitable conditions for the carriage of this
cargo.
2.2. Type of cargoes
Group A consists of cargoes which may liquefy if shipped at a moisture content
in excess of their transportable moisture limit. Group A cargoes may liquefy during a
voyage even when they are cohesive and trimmed level. Liquefaction can result in
cargo shift. This phenomenon may be described as follows:
1. the volume of the spaces between the particles reduces as the cargo is
compacted owing to the ship motion, etc.;
2. the reduction in space between cargo particles causes an increase in water
1 International Maritime Solid Bulk Cargoes Code adopted by IMO
6

pressure in the space; and
3. the increase in water pressure reduces the friction between cargo particles
resulting in a reduction in the shear strength of the cargo.
Group B consists of cargoes which possess a chemical hazard which could give
rise to a dangerous situation on a ship. Some of these materials are classified as
dangerous goods and others are materials hazardous only in bulk (MHB). It is essential
to obtain current, valid information about the physical and chemical properties of the
cargoes to be shipped in bulk, prior to loading.
Group C consists of cargoes which are neither liable to liquefy (Group A) nor to
possess chemical hazards (Group B).
2.3. Provision of information regarding cargo
Cargo information (see Annex 1) shall be confirmed in writing and by appropriate
shipping documents prior to loading. The cargo information shall include:
the BCSN when the cargo is listed in the IMSBC Code. Secondary names
may be used in addition to the BCSN;
the cargo group (A&B, A, B, or C);
the IMO Class of the cargo, if applicable;
the UN number preceded by letters UN for the cargo, if applicable;
the total quantity of the cargo offered;
the stowage factor;
the need for trimming and the trimming procedures, as necessary;
the likelihood of shifting, including angle of repose, if applicable;
additional information in the form of a certificate on the moisture content of
the cargo and its transportable moisture limit in the case of a concentrate
or other cargo which may liquefy;
likelihood of formation of a wet base (contains in IMSBC Code);
toxic or flammable gases which may be generated by cargo, if applicable;
flammability, toxicity, corrosiveness and propensity to oxygen depletion of
the cargo, if applicable;
self-heating properties of the cargo, and the need for trimming, if
applicable;
properties on emission of flammable gases in contact with water, if
7
7
applicable;
radioactive properties , if applicable; and
any other information required by national authorities.
2.4. Definitions and terminologies associated with the carriage of bulk
cargoes
(1) Angle of Repose ( AOR) This is maximum slope angle of non-cohesive (i.e. ,
free flowing) granular material. It is measured as the angle between a horizontal
plane and the cone slope of such material.
The angle of repose will be in the range of 0o - 90o.
Free flowing liquids will have zero AOR. Whereas
materials with high density & high coefficient of
friction will have the tendency to make large AOR. Figure 1. Angle Of Repose (AOR)
Materials with large angle of repose will form large piles while with less angle of
repose will tend to flatten up , making it more liable to shift and slide during
transport.
As far as solid bulk cargoes are concerned, the angle repose is required for non-
cohesive substances only. For cohesive substances (which may stick together) , the
value of AOR is not applicable.
(2) Bulk Cargo Shipping Name (BCSN) It identifies a bulk cargo during transport
by sea. When a cargo is listed in IMSBC Code, the Bulk Cargo Shipping Name of
the cargo is identified by capital letters in the individual schedules or in the index.
When the cargo is a dangerous good as per IMDG code, Proper Shipping Name
of that cargo is the Bulk Cargo Shipping Name.
Each solid bulk cargo in this Code has been assigned a Bulk Cargo Shipping
Name (BCSN). When a solid bulk cargo is carried by sea it shall be identified in the
transport documentation by the BCSN. The BCSN shall be supplemented with the
United Nations (UN) number when the cargo is dangerous goods.
(3) Bulk density Means the weight of solids, air and water per unit volume. Bulk
density is expressed in kilograms per cubic meter (kg/m3) , in general. It should
8
8
be noted that the void spaces in the cargo may be filled with air and water.
(4) Cargo space Means any space in a ship designated for carriage of cargoes.
(5) Cargoes which may liquefy Means cargoes which contain a certain proportion
of fine particles and a certain amount of moisture. They may liquefy if shipped
with moisture content in excess of their transportable moisture limit.
(6) Cohesive material Means materials other than non-cohesive materials.
(7) Combination carriers (OBO or O/O) a ship whose design is similar to a
conventional bulk carrier but is equipped with pipelines, pumps and inert gas
plant so as to enable the carriage of oil cargoes in designated spaces.
(8) Competent Authority Means any national regulatory body or authority
designated or otherwise recognized as such for any purpose in connection with
IMSBC Code.
(9) Concentrates Means materials obtained from a natural ore by a process of
enrichment or beneficiation by physical or chemical separation and removal of
unwanted constituents.
(10) Conveyor system Means the entire system for delivering cargo from the
shore stockpile or receiving point to the ship.
(11) Flow moisture point (FMP) Means the percentage moisture content (wet
mass basis) at which a flow state develops under the prescribed method of test
in a representative sample of the material
(12) Flow state Means a state occurring when a mass of granular material is
saturated with liquid to an extent that, under the influence of prevailing external
forces such as vibration, impaction or ships motion, it loses its internal shear
strength and behaves as a liquid.
(13) High-density solid bulk cargo Means a solid bulk cargo with a stowage
factor of 0.56 m3/t or less.
(14) Incompatible materials Means materials that may react dangerously
when mixed. They are subject to the segregation requirements and the
schedules for individual cargoes classified in Group B.
9
9
(15) Materials hazardous only in bulk (MHB) Means materials which may
possess chemical hazards when carried in bulk other than materials classified as
dangerous goods in the IMDG Code.
(16) Moisture content ( MC) Means that portion of a representative sample
consisting of water ice or other liquid expressed as a percentage of the total wet
mass of that sample.
(17) Moisture migration Means the movement of moisture contained in a
cargo by settling and consolidation of the cargo due to vibration and ship's
motion. Water is progressively displaced, which may result in some portions or all
of the cargo developing a flow state.
(18) Pour Means the quantity of cargo poured through one hatch opening as
one step in the loading plan, i.e. from the time the spout is positioned over a
hatch opening until it is moved to another hatch opening.
(19) Representative test sample Means a sample of sufficient quantity for the
purpose of testing the physical and chemical properties of the consignment to
meet specified requirements.
(20) Transportable Moisture Limit (TML) of a cargo which may liquefy means
the maximum moisture content of the cargo which is considered safe for carriage
in ships not complying with the special provisions of subsection 7.3.2. It is
determined by the test procedures, approved by a competent authority, such as
those specified in paragraph / of appendix 2.
(21) Trimming Means any leveling of a cargo within a cargo space, either
partial or total. Trimming the cargo means making the surface if the cargo as
level as possible. Trimming a cargo reduces the likelihood of the cargo shifting
and minimizes the air entering the cargo, which could lead to spontaneous
heating. To minimize these risks, cargoes shall be trimmed reasonably level, as
necessary. (22) Ventilation Means exchange of air from outside to inside a cargo space.

2.5. Properties and characteristics regarding coal cargoes
Coal is considered one of the high-risk cargoes. Whenever coal is shipped from
any place, the history of previous shipment must be known so as to be aware of the
hazards of that particular coal.
(1) Spontaneous heating Coal is a combustible material, if exposed to naked fire will catch fire. It is very liable to spontaneous heating.
(2) Emission of Methane Coals may emit methane, a flammable gas. When mixed
with air, methane forms an explosive mixture. Methane is lighter than air and
may, therefore, accumulate in the upper region of the cargo space or other
enclosed spaces. If the cargo space boundaries are not tight, methane can seep
through into spaces adjacent to the cargo space.
(3) Corrosion Some coals may be liable to react with water and produce acids
which may cause corrosion.
(4) Liquefaction is the process where
moisture in the cargo migrates to
the surface due to compaction and
vibration resulting in flow state.
This kind of coal is slurry, coal duff
and mud coal.
Figure 2. Iron ore fines before and after
liquefaction.
The surface of the cargo behaves like a liquid and causes stability issues.
3. Bulk carriers
Safety of life at Sea, SOLAS defines solid bulk cargoes as
”Any cargo, other than liquid or gas, consisting of a combination of particles, granules or any larger pieces of material generally uniform in composition, which is loaded directly into the cargo spaces of a ship without any intermediate form of containment."
3.1. World fleet growth and principal vessel types
Following an annual growth of almost 10 per cent, in January 2012 the world fleet
11
11
reached a total tonnage of 1,534 million dwt. At the beginning of the year, there were
104,305 seagoing commercial ships in service. The largest growth of tonnage was in
dry bulk carriers, plus 17 percent, bringing this category to 40.6 per cent of the world
total capacity; the world dry bulk fleet has surged by 60 per cent in just four years. Oil
tanker capacity, which grew by 6.9 per cent, now accounts for 33.1 per cent of the world
fleet. Container ships, after an increase of 7.7 per cent, make up 12.9 per cent of the
world tonnage. The conventional general cargo fleet continued its relative decline, being
the only major vessel type with a smaller tonnage in January 2012 than one year earlier.
Since 1980, the general cargo fleet has declined by 7 per cent, while the remainder of
the world fleet grew by more than 150 per cent.

3.2. Approximate vessel-size regarding dry bulk
Typical classification of bulk carriers can be done as per the size. However they
can be classed as per the gear e.g. gearless or geared or depending upon the usage
e.g. combined carrier, self unloader etc. There are special ships designed to pass
through great lakes called Lakers.

Table 2. Vessel-size regarding dry bulk
3.3. Dry bulk ships
Freight costs are an important component of the landed price of most dry bulk
commodities. In order to remain competitive and maintain reasonable profit margins,
distant suppliers such as Brazilian iron ore producers see the use of large ships as a
13
13
prerequisite to achieve economies of scale. It may be useful to recall that transporting
dry bulk in a small Handymax ship was, in March 2012, three times as expensive per
ton-mile than shipping the cargo in a large Capesize bulk carrier.
The year 2011 saw a particularly
interesting development in the dry bulk
market, as a major supplier of iron ore
aimed at gaining more control over the
supply chain by ordering historically large
vessels. To benefit from the above-
mentioned economies of scale in the iron
ore trade, in 2011 and early 2012 the
Brazilian mining conglomerate Vale took
delivery of the largest existing cargo
carrying ships, the so-called Valemax
ships of up to 400,000 dwt capacity. The
ships created a difficult situation for Vale,
however, as permission for them to enter
Chinese ports was still under discussion
with Chinese authorities. Reportedly,
Chinese shipowners and iron ore
producers opposed the entry of the
Brazilian Valemax ships into Chinese
ports, arguing that the operation of such
large ships might not be safe, and fearing
that Vale could gain monopolistic control
of the supply chain for iron ore. Ports
would also need to expand stockpiling
capacity to store the imported ore.
Table 3. World fleet by principal vessel types, 2011 - 2012 (Beginning of year
figures, thousands of dwt, percentage share in italics)
Vale is planning to take delivery of 35 such ships by the end of 2013, with a total
investment of $4.2 billion. The Valemax ships are built in shipyards in the Republic of
Korea and in China. Keeping in mind the benefits of lower transport costs, energy
efficiency and further South-South trade and collaboration between Brazil and China,
several industry observers expressed hope that the ban for Valemax ships to enter
Chinese ports would soon be lifted. History has shown, however, that attempts by
14
14
exporters to control the maritime supply chain have often been short-lived, and in the
longer term the traditional shipowners may resume their role as providers of maritime
transport services.
3.4. Bulk carriers and SOLAS
The International Convention for the Safety of Life at Sea, 1974 (SOLAS
Convention), as amended, deals with various aspects of maritime safety and contains,
in parts A and B of chapter VI and part B of chapter VII, the mandatory provisions
governing the carriage of solid bulk cargoes and the carriage of dangerous goods in
solid form in bulk, respectively.
Towards the end of the 1980s, a number of bulk carriers sank in a series of highly
publicized maritime incidents. In response to these incidents, the IMO adopted a set of
amendments called the Enhanced Survey Programme to the SOLAS Convention in
order to enhance bulk carrier inspection.
After the ESP came into force in January 1996, however, the number of accidents
did not decrease. This led to the adoption of additional amendments to the SOLAS
Convention and the introduction of further safety measures. The new amendments form
Chapter XII of the SOLAS Convention and include new standards for flooding damage
stability and other requirements.
Detailed fire protection arrangements for ships carrying solid bulk cargoes are
incorporated into chapter II-2 of the SOLAS Convention by regulations 10 and 19.
Attention is drawn to regulation II-2/19.4 (or II-2/54.3) of the SOLAS Convention as
amended. This provides for an appropriate document as evidence of compliance of
construction and equipment with the requirements of regulation II-2/19 (or II.2/54) to be
issued to ships carrying dangerous goods in solid form in bulk, as defined in regulation
VII/7 of the Convention, except class 6.2 and class 7, which are:
- cargo ships of 500 gross tonnage or over constructed on or after 1 September 1984;
or
- cargo ships of less than 500 gross tonnage constructed on or after 1 February 1992.

3.5. Bulk carriers and IACS2
The International Association of Classification Societies (IACS) is introducing a
series of manuals with the intention of giving guidelines to assist the surveyors of IACS
Member Societies, and other interested parties involved in the survey, assessment and
repair of hull structures for certain ship types.
Around the year 2000, while bulk carrier safety discussions were still ongoing,
IACS began studying ways to improve the safety of tanker hull structures in response to
a number of accidents involving oil tankers. At this point, investigations into bulk carrier
safety were already well underway and IACS moved to include oil tankers in its efforts
as well. In 2003, as the investigations into bulk carrier safety were coming to a close,
IACS decided to proceed with the development of common structural rules (CSR) for
both bulk carriers and oil tankers. In so doing, the individual structural rules of each
classification society were to be unified, with the hope of developing a more rigorous
and transparent set of rules.
After several years of study and discussions with various parts of the maritime
industry, IACS adopted the CSR in December 2005 for application to new ships
contracted after 1 April 2006.
Some manual gives guidelines for a bulk carrier type ship which is constructed
with a single deck, single skin, double bottom, hopper side tanks and topside tanks in
cargo spaces, and is intended primarily to carry dry cargo, including ore, in bulk.
2 International Association of Classification Societies

Figure 4. Handymax Carrier
The guidelines focus on the IACS Member Societies’ survey procedures but may
also be useful in connection with inspection/examination schemes of other regulatory
bodies, owners and operators.
Ship designers often say that the bulk carrier is a rational structure with a minimal
amount of waste. The triangular shaped topside tanks situated under the main deck and
the double bottom and hopper tanks at the bottom of the ship help to strengthen the
hull, enabling the cargo holds to be made larger. Furthermore, the hold structure makes
it possible for the cargo to be loaded without the need for trimming, allowing bulk
carriers to carry large volumes of cargo efficiently. It is important for ships carrying
cargo in bulk to have as large a hold capacity as possible, and current bulk carrier
designs have been refined to meet such objectives. Hopper tanks not only play a role in
strengthening the hull, but they also make it easier to unload cargo. This multi-
functionality is a perfect example of why the bulk carrier is considered to be an
extremely rational structure.
17

Figure 5. Typical cargo hold configuration for a single skin bulk carrier
In general, the plating comprising structural items such as the side shell, bottom
shell, strength deck, transverse bulkheads, inner bottom and topside and hopper tank
sloping plating provides local boundaries of the structure and carries static and dynamic
pressure loads exerted by, for example, the cargo, bunkers, ballast and the sea. This
plating is supported by secondary stiffening members such as frames or longitudinals.
These secondary members transfer the loads to primary structural members such as
the double bottom floors and girders or the transverse web frames in topside and
hopper tanks, etc. see Figure 6.
Figure 6. Nomenclature for Typical Transverse Section in way of a Cargo Hold
Since 1991, it has been a requirement for new bulk carriers to apply a protective
coating to the structure in water ballast tanks which form part of the hull boundary, and,
since 1993, to part of the side shell and transverse watertight bulkheads structures in
18
18
way of the cargo holds.
The International Maritime Organization (IMO), in 1997 SOLAS Conference,
adopted structural survivability standards for new and existing bulk carriers carrying the
high density cargoes. All new single side skin bulk carriers, defined as ships built on or
after 1st July 1999, are required to have sufficient strength to withstand the flooding of
any one cargo hold taking dynamic effects into account. All existing single side skin bulk
carriers, defined as ships built before 1 July 1999, must comply with the relevant IACS
criteria for assessing the vertically corrugated transverse watertight bulkhead between
the first two cargo holds and the double bottom in way of the first cargo hold with the
first cargo hold assumed flooded. The relevant IMO adopted standards, IACS UR S19
and S22 for existing ships, and recommended standards, IACS UR S17, S18 and S20
for new ships, and the extent of possible repairs and/or reinforcements of vertically
corrugated transverse watertight bulkheads on existing bulk carriers are freely available
at IACS web site www.iacs.org.uk.
From 1 July 2001, bulk carriers of 20,000 DWT and above, to which the
Enhanced Survey Programme (ESP) requirements apply, starting with the 3rd Special
Survey, all Special and Intermediate hull classification surveys are to be carried out by
at least two exclusive surveyors. Further, one exclusive surveyor is to be on board while
thickness measurements are taken to the extent necessary to control the measurement
process.
4. Cargo operations. Loading and unloading
To make it possible to plan the cargo stowage, loading and unloading sequences,
the cargo terminal should provide the ship with the following information well in
advance:
Cargo characteristics; stowage factor, angle of repose, amounts and special properties.
Cargo availability and any special requirements for the sequencing of cargo operations.
Characteristics of the loading or unloading equipment including number of loaders and unloaders to be used, their ranges of movement, and the terminal's nominal and maximum loading and unloading rates, where applicable.
19
19
Minimum depth of water alongside the berth and in the fairway channels.
Water density at the berth.
Air draught restrictions at the berth.
Maximum sailing draught and minimum draught for safe manoeuvring permitted by the port authority.
The amount of cargo remaining on the conveyor belt which will be loaded onboard the ship after a cargo stoppage signal has been given by the ship.
Terminal requirements/procedures for shifting ship.
Local port restrictions, for example, bunkering and deballasting requirements etc.
Cargo trimming is a mandatory requirement for some cargoes, especially where
there is a risk of the cargo shifting or where liquefaction could take place. IACS
recommends that the cargo in all holds be trimmed in an attempt to minimise the risk of
cargo shift.
During the derivation of the cargo stowage, and the loading or unloading plan, it
is recommended that the hull stress levels be kept below the permissible limits by the
greatest possible margin.
A cargo loading/unloading plan should be laid out in such a way that for each step of the cargo operation there is a clear indication of:-
The quantity of cargo and the corresponding hold number(s) to be loaded/unloaded.
The amount of water ballast and the corresponding tank/hold number(s) to be discharged/loaded.
The ship's draughts and trim at the completion of each step in the cargo operation.
The calculated value of the still water shear forces and bending moments at the impletion of each step in the cargo operation.
Estimated time for completion of each step in the cargo operation.
Assumed rate(s) of loading and unloading equipment.
Assumed ballasting rate(s)
The loading/unloading plan should indicate any allowances for cargo stoppage
20
20
(which may be necessary to allow the ship to deballast when the loading rate is high),
shifting ship, bunkering, draught checks and cargo trimming.
Prior to the commencement of cargo loading operations, it should be determined
that:
no structural damage exists. Any such damage is to be reported to the respective
classification society and cargo operations are not to be undertaken.
the bilge and ballast systems are in satisfactory working condition.
The officer in charge should ensure that,
the cargo operation and intended ballast procedure are synchronised. draught surveys are conducted at appropriate steps of the loading plan to verify
the ship's loading condition. The draught readings, usually taken at amidships and the fore and aft perpendiculars, should be in good agreement with values calculated in the loading plan.
ballast tanks are sounded to verify their contents and rate of ballasting/deballasting.
the cargo load is in agreement with the figures provided by the terminal.
the STILL WATER SHEAR FORCE, STILL WATER BENDING MOMENT and, where appropriate, hold cargo weight versus draught calculations are performed at intermediate stages of the cargo operation. These results should be logged, for recording purposes, against the appropriate position in the loading plan.
Following a deviation from the loading plan, the officer in charge should take all
necessary corrective actions to:
Restore the ship to the original loading/unloading plan, if possible, or Replan the rest of the loading/unloading operation, ensuring that the stress and
operational limits of the ship are not exceeded at any intermediate stages.
The modified loading/unloading plan should be agreed by both the officer
responsible for the loading plan and the cargo terminal representative. Cargo operations
should not resume until the officer in charge gives a clear indication to the terminal of
his readiness to proceed with the cargo operation.
4.1. Potential problems
Exceeding the maximum permissible cargo load in any hold will lead to over-
21
21
stressing of local structure. Over-stressing of the local structure will occur when:
The weight of cargo loaded into a hold exceeds the maximum permissible value specified at full draught.
The weight of cargo loaded into adjacent holds exceeds the maximum combined value at full or reduced draught.
Over-stressing of the local structure may also occur when the weight of cargo
loaded into an individual hold has insufficient support of upward buoyancy force; this
circumstance can occur when cargo is transported by the ship in a shallow draught
condition (for example, partial load condition with some holds full and remaining holds
empty). Also, loading cargo in a shallow draught condition can impose high stresses in
the double bottom, cross deck and transverse bulkhead structures if the cargo in the
hold is not adequately supported by the buoyancy upthrust. If applicable, the cargo
weight limits for each cargo hold, and two adjacent cargo holds, as a function of
draught, (the local loading criteria) are not to be exceeded.
High loading rates may cause significant overloading within a very short space of
time. The officer in charge should be prepared to STOP cargo operations if the loading
operation deviates from the agreed loading plan. There are three main problems
associated with high loading rates which may result in over-stressing the ship's
structure, namely:
The sensitivity of the global hull girder STILL WATER SHEAR FORCE and STILL WATER BENDING MOMENT.
Overloading the local structure.
Synchronisation of the ballasting operations.
It is recommended that high density cargo be stowed uniformly over the cargo
space and trimming be applied to level the cargo, as far as practicable, to minimise the
risk of damage to the hull structure and cargo shift in heavy weather.
The distribution of cargo in a hold, and water ballast distribution, have an
important influence on the resultant stress in the hull structure. The double bottom and
the cross deck structure are designed based upon a trimmed cargo distributed
symmetrically in a hold space.
Still water shear forces and bending moments given in the ship's loading manual
and the corresponding calculations from onboard loading instruments are based on an
22
22
even distribution of cargo in a hold space, unless otherwise indicated.
Still water shear force and bending moments calculated with an onboard loading
instrument do not consider the torsional loads acting on the hull girder resulting from
asymmetrical cargo or ballast loading.
Water ballast should always be carried symmetrically in port and starboard tanks
with equal levels of filling. The final fill level of all water ballast tanks and holds must
satisfy the requirements specified in the ship's approved loading manual to avoid
damage to the internal structure due to sloshing effects.
Other potential problems may be appear as a effects of: the lack of effective ship/shore communication - may increase the risk of
inadvertent overloading of the ship's structure It is important that there is an agreed procedure between the ship's officers and the terminal operators to STOP cargo operations. The communication link established between the ship and the terminal should be maintained throughout the cargo operation.
exceeding the assigned load line marks - all ships engaged on international voyages are assigned with load line marks in accordance with the provisions of the International Load Line Convention 1966. The appropriate lines marked on the ship's side shall not be submerged at any time during the seagoing voyage To allow for the difference between the dock water density and the sea water density, the ship may be loaded beyond the appropriate mark by the dock water allowance. The dock water allowance is only applicable in a port environment. It is a statutory requirement that the ship is not to be loaded beyond the limits specified in the Load Line Certificate.
partially filled ballast holds or tanks - sailing with partially filled ballast holds is prohibited unless the approved loading manual approves of such a practice. Cargo holds designed for partially filled in harbour for the purpose of reducing the ship's air draught are not to contain any water ballast while at sea.
inadequate cargo weight measurement during loading - during cargo loading operations it is important to ascertain the cargo weight loaded into each individual cargo hold and the associated loading rate. Overloading the cargo hold will increase the stress levels in the ship's structure. At high loading rate ports, where there is no suitably positioned cargo weighing equipment, the ship's cargo officer should request that the terminal stops loading to allow draught surveys and displacement calculations to be performed to ensure compliance with the agreed loading plan. An appropriately positioned cargo weighing device, which can provide continuously, or at least at each step, an accurate indication of the weight of cargo that has been loaded into each individual hog is an important piece of equipment which can be used to avoid overloading of individual cargo holds.
structural damage - terminal operators should be aware of the damage that their cargo handling equipment can inflict on the ship's structure It is important that the protective coatings in cargo holds and water ballast tanks are maintained The cargo holds and deck areas should be inspected by the ship's deck officers upon completion of cargo discharge to identify any signs of physical damage, corrosion or coating damage to the ship's structure. Where hull damage is identified; which may affect the integrity of the hull structure and the seaworthiness of the ship, it should be reported accordingly to the classification
23
23
society.
4.2. Aspects regarding shear forces and bending moments
The shear forces and bending moments must be calculated before commnecement
of any of the following processes:
Planned loading and deballasting sequence.
Planned discharging and ballasting sequence.
Any change of ballast.
Any change in loading or discharching sequence.
Any instance when deballasting is delayed and becomes out of sequence with
loading.
Any instance when ballasting is delayed and becomes out of sequence with
discharching.
Taking of bunkers, steb by step (ie, tank by tank).
Consumption of bunkers, step by step (ie, tank by tank).
Dry docking.
If the allowable values are exceeded there is danger that the ship’s structure will be
permanently damaged – it is even possible for the ship to break into two. The
importance of completing the calculations and ensuring that the stresses are not
exceede cannot be started too strongly. The most likely reasons for failure to comply
with this requirement are the underlisted; they must be avoided:
Failure to understand the calculations.
Data provided in language which is not understood.
Computer breakdown.
Inability to make the manual calculation when the computer has broken down.
Stability data unreadable.
Change in loading/unloading programme.
Failure to follow loading/discharging programme.
Pessure of work.
Negligent practices.
Ommercial pressure.
Routine procedure undertaken without planning.

5. Establishing quantity of cargo loaded or discharged
5.1. Shorebased methods of weighing
The quantity of cargo loaded aboard a bulk carrier can be measured in a variety of
ways. The only method which directly involves the ship’s personnel is the draught
survey. Electronic weighining of cargo on conveyor belt. The most common method of
weighing used at modern loading terminals is the belt device. This device continuously
weighs the material on a selected length of the loading conveyor belt and multiplies this
instantaneous weight value by the belt speed. Electronic weighing of cargo in grab. Cargo beeing discharged or loaded by grab
can be weighed whilst in the grab by an electronic system. A computerised system can
then record and total the tonnage handled. Talling of number of grabloads. It is reported that eceivers have taken delivery of a
part cargo with the claim that each grabload discharged, filled to capacity, weighed two
tonnes. Weighing of trucks on weighbridge. For accuracy this metod depends upon all
trucks passing over the weighbridge with the results being accurately recorded and
upon the tare weight of each truck being accurately known. Automatic bulk grain weighers. These machines are suitable for weighing grain
and free-flowing materials fed from elevators, conveyor belts, storage hoppers or silos. Shorebased systems in general. At best, all the foregoing methods cand be only as
accurate as the design of the weighing equipment allows. At worst, if the equipment is
not regularly calibrated and if not ll cargo is weighed, the results may bear little
relationship to reality.
5.2. Draught survey
The ships’ method of determining the amount of cargo loaded is by means of draught
surveys taken before and after the loading is carried out. With the data so obtained the
ship’s displacement (the volume and therefore the weight of water displaced by the
ship) before and after loading can be calculated.
It is in Master interests to ensure that the results are as accurate as possible. In
special cases, the surveyor will have the benefit of equipment and instruments not
25
25
found aboard the normal bulk carrier, but in most instances the ship’s Master or officer
with careful attention to accuracy and procedure can obtain results quite as good as
those of the surveyor.
A complete displacement calculation, fully explained, is to be found at Annex 2.
Also, the United Nations draught survey code can be strongly recommended for the
clarity and detail with which it describes good procedures, and for well-designed survey
forms which it provides.
Conditions for the commencement of survey:
Vessel afloat.
No cargo being worked.
No ballast, fuel, fresh water, etc. being pumped or run.
No hatch covers being opened or closed.
No spares or stores being shipped or landed.
All ballast tanks full or empty.
Ship upright.
Little or no tide or current running, where possible.
Seas not unduly rough where possible.
Temperature difference between sea water and ship’s decks not excessive
where possible.
5.3. Possible sources of error
Occasionaly it will be found that the results obtained from a draught survey are
unexpected. The ship’s constant may be found to be much larger than the normal value
for that ship’s, or a negative constant may be calculated. The ship’s figure for the
tonnage of cargo lifted may differ from the shore figure by an unusually large amount. If
the ship’s officer and surveyor works independently, but compares figures at each stage
of the calculation, then calculation errors are minimised. Since the discrepancy may be
the result of a mistake in the draught readings or soundings, these shoud be rechecked,
if still possible.
If the result remains unchanged it will be necessary to look further for an explanation.
Where possible data should be rechecked by a different method. It is useful to consider
whether the discrepancy has occurred once only, or occurs every voyage.
Always, we must investigate any substantial changes in the calculated value of the
ship’s constant. Accurate and reliable draught surveys are more difficult to achieve
26
26
when a vessel has a large stern trim, such as may occur when a vessel has been partly
deballasted to permit a quick loading.
The interest of ship and terminal do not always coincide, and the Master should
ensure that an accurate draught survey is made, which will enable him to produce the
correct amount of cargo at the discharge port.
