1 INTRODUCTION

1.1 General The present document describes the stability performances of Venus 2, following the rules and regulations issued by the Norwegian Maritime Authority, Regulations of 19 December 2014 No. 1853 on the construction and supervision of small cargo ships. The vessel has been assessed against cargo carrying operations, as well as lifting, towing and anchor handling operations. The stability assessment has been developed using Autohydro Pro 6.8.0, the stability package developed by Autoship Systems Corporation.

3 STABILITY CRITERIA

3.1 Cargo carrying operation The stability performances of Venus 2 have been assessed against the intact stability criteria set out by the

Norwegian Maritime Authority for small cargo ships. These requirements were issued together with the

Regulations of 19 December 2014, No. 1853 for closed ships, which state that the vessel should comply with the

following stability criteria:

a) The area below the righting arm curve (GZ curve) shall be at least 0.055 metre radians calculated up to an angle of heel of 30 degrees, and at least 0.09 metre radians calculated up to 40 degrees or the angle of flooding if that angle is less than 40 degrees. In addition, the area below the GZ curve between the heeling angles of 30 and 40 degrees, or between 30 degrees and the angle of flooding if that angle is less than 40 degrees, shall be at least 0.03 metre radians.

b) The righting arm (GZ) shall be at least 0.20 metres at an angle of heel of 30 degrees or more.

c) The angle of heel at which the righting arm (GZmax) is at its maximum value shall not be less than 25 degrees.

d) The initial metacentric height (GM) shall be at least 0.15 metres.

When the ship because of its shape fails to comply with the first paragraph subparagraph c, the first paragraph

subparagraphs a and c may be replaced by the following:

a) The area below the GZ curve shall be at least 0.07 m-rad calculated to an angle of heel of 15 degrees when the maximum righting arm (GZmax) occurs at 15 degrees, and 0.055 m-rad up to 30 degrees when GZmax occurs at 30 degrees or more. When GZmax occurs between 15 and 30 degrees, the area requirement below the GZ curve up to the angle where GZmax occurs shall be determined by this formula: Minimum area = 0.055 + 0.001 (30 degrees -θmax), where θmaxis the angle where GZmax occurs. In addition, the area below the GZ curve between 30 and 40 degrees, or between 30 degrees and the angle of flooding if the latter is less than 40 degrees, shall be not less than 0.03 m-rad.

b) The angle of heel where GZmax occurs shall not be less than 15 degrees.

11

3.2 Towing operations

Ships carrying out towing operations shall be closed ships.

When a ship carrying out towing operations is exposed to a transverse force giving the ship a transverse speed

through the water of 5 knots, the first intersection between the heeling arm curve and the righting arm curve (GZ

curve) shall occur at an angle which is less than the angle of flooding.

When a ship carrying out towing operations is exposed to a transverse force equal to the ship’s bollard pull

multiplied by 0.65, the area between the righting arm curve (GZ curve) and the heeling arm curve calculated from

the first point of intersection to the angle which occurs first of 40°, the angle of GZmax and the angle of flooding,

shall be equal to or greater than 0.010 m-rad. The vertical arm of the heeling moment shall be taken from the

centre of the propeller(s) to the fastening point of the hawser.

3.3 Lifting and anchor handling operations Ships which shall use deck crane, and ships which shall carry out anchor-handling operations, shall be closed

ships.

The maximum angle of heel due to heeling moment from the crane shall be 7 degrees, or the angle resulting in

parts of the freeboard deck being located 200 mm from the waterline, if this angle is smaller. The area between

the righting arm curve (GZ curve) and the heeling arm curve calculated from the first point of intersection to the

angle which occurs first of 40° and the angle of flooding, shall be equal to or greater than 0.090 m-rad.

The maximum angle of heel may be between 7 and 10 degrees if the following conditions are satisfied when the

crane or winch is operating at maximum loading moment:

a) The righting arm curve (GZ curve) has a positive extent of at least 20 degrees beyond the state of equilibrium. Flooding shall be assumed to take place through openings which do not have weathertight closing appliances.

b) The area requirement of the second paragraph is satisfied.

c) No parts of the freeboard deck are located less than 200 mm from the waterline.

Information from the manufacturer shall be available concerning the maximum angle of heel for which the cargo-

handling appliance is intended. The maximum permitted angle of heel of the second and third paragraphs shall

not exceed the maximum angle of heel from the manufacturer.

If, when lifting by crane, counter ballasting is used in order to counterbalance heeling moment due to weight in the

crane, the consequence of loss of crane load shall be considered.

5.5 Loading conditions for lifting operations

Venus 2 is equipped with the HS Marine AK 30 LHE2 crane with two hydraulic boom extensions as presented

below:

Figure 7 - HS Marine AK 30 LHE2

After computing the heeling moments with respect to vessel’s origin, it was found that the most severe boom

extension is 5.50m, for a safe working load of 3.935t.

The analysis was carried out for three boom orientations (sideways, 45degrees and aft) and the maximum vertical

extension, as showed below:

Figure 8 - Boom orientations considered

The crane load has been reduced from the safe working load of 3.935t to comply with stability criteria. The

maximum value for each boom orientation is presented below:

Table 4 - Reduced crane load for each orientation

During lifting operations, the amount of cargo on deck was reduced from 16t to 5t, to ensure positive stability and

a minimum freeboard of 200mm all around the vessel.

8 NOTES ON STABILITY

One of the main duties of the master is to ensure that the vessel is stable during all operations. The information in this chapter is meant as a guidance to the user, and a help to better understand and use the information contained in the stability manual.

8.1 Stability – definition A vessel with good stability will straighten itself quickly at moderate heeling angles and will sustain larger heeling angles without capsizing. The vessels stability is dependent on two factors:

- The vessels inherent stability due to the hull shape - The stability the crew imposes on the vessel

The inherent stability of the vessel is given and cannot be changed without changing the hull shape. Safe operation of the vessel is dependent on how the vessel is loaded, what weather conditions it is subject to, and how equipment onboard is used.

8.2 Buoyancy and center of gravity For calculating static stability only two forces are relevant, buoyancy and gravity. Buoyancy is the force that keeps the vessel afloat. It is acting upwards thought the center of the submerged volume of the hull. Gravity acts downwards through the vessels center of gravity.

The gravity force, G, acts through the centre of gravity of the vessel.

The buoyancy force B, acts throguh the centre of the underwater volume of the hull

The point/center through which the buoyancy acts depends on the hull shape. It is normally referred to as B. The point/center of gravity is referred to as G. The center of gravity of the vessel changes with the amount of cargo and consumables onboard and their location.

191

Cargo placed low yields an overall low centre of gravity

Cargo placed high yields an overall high centre of gravity

Weights (cargo and consumables) placed below the vessels center of gravity will move the center of gravity down. Weights placed above the vessels center of gravity will move the center of gravity up.

Center of buoyancy will move as the vessel heels.

Gravity will always act through the center of gravity.

Buoyancy is constant for a given displacement and will always be equal to the weight of the vessel. The point the buoyancy acts through will move when the vessel trims or heels, so that it always is situated at the center of the submerged volume of the hull. To find a simple relation to express stability, the points B (center of buoyancy) and G (center of gravity) is used. The horizontal distance from the center of gravity G to the center of buoyancy B gives a measure of the vessels ability to recover stability and is called metacentric height. The buoyancy and gravity create a moment that straightens the vessel. The arm of this moment is GZ.

192

The righting arm, GZ, is the horizontal distance between B and G.

K is the keel, and KG is thus the distance to the center of gravity.

8.3 The GZ-curve The GZ-curve is a key parameter in vessel stability theory. It is possible to calculate the size of the righting arm for different heeling angles. By plotting these values in a graph, one gets the GZ-curve. The GZ-curve serves as a tool for finding the righting arm at different heel angles and checking stability criteria to ensure class/authority compliance. There are mainly four dimensions that describe the stability: - Maximum righting arm (max GZ) trim - The span of the curve (range of stability) - Area below the curve - GM (metacentric height)

GZ curve

The righting arm (GZ) is a measure of the vessel’s ability to return to the upright position on its own when subject to wind, waves or other external forces. The range of stability is a measure of how much the vessel can heel before it capsizes.

193

The shape of the curve will vary from vessel to vessel depending on the hull shape and how it is loaded (center of gravity). Common for all vessels in all loading conditions is that they need to satisfy the same stability requirements. It is thus appropriate to look at the area below the GZ-curve. The area below the curve is a measure of the restoring energy of the vessel.

8.4 GM (the metacentric height)

GM is a measure of the vessels stability in upright position

GM (metacentric height) is the distance from G (centre of gravity) to M (metacenter) which is an imagined point. It is placed in the crossing between the VCG line (vertical centre of gravity) and the vertical line through B (centre of buoyancy). GM is a way of expressing the vessels stability at small heeling angles. GM can be determined by using the

slope of the GZ-curve at 0. The height of this slope at 57,3 (1 radian) is the vessels GM for the present loading condition. A high GM value is an expression for good stability and a stiff vessel. A low GM value results in slower roll motions and indicates poorer stability. GM is not a suitable measure of stability at large heel angels.

194

8.5 Loading conditions It is necessary to carry out a table of loads to determine the displacement and the centre of gravity for a loading condition. One is able to determine which pre-calculated loading condition is most representative for the current loading condition by use of a set of loading conditions and an empty example.



FUEL OIL 9.74 100.00


This method may be used to obtain the position of the centre of gravity and thereby the stability of the vessel. The weight and centre of gravity for all tanks, loads and equipment are required to be known. Use the vessels stability manual as reference for such calculations. These values can be put into to the KG-curves when the vessels displacement and centre of gravity are calculated by use of this method. See example of usage of VCG curve in the stability manual.

195

8.6 Relationships which have impact on the vessels stability

8.6.1 The centre of gravity of the loads

A high centre of gravity will result in a degraded stability. When loading the vessel, the centre of gravity is moved. The vessels vertical centre will move up if the load is put for example on deck or somewhere else high in vessel. The centre of gravity will be lowered if the load is placed somewhere low in the vessel.

A load placed low in the vessel will result in a lowered VCG and thereby an increased GM

A load placed high in the vessel will result in a raised centre of gravity and thereby a decreased GM

196

Any consumption of fuel or fresh water will have an impact on vessel’s stability. By removing a weight placed low in the vessel, the centre of gravity will rise.

8.6.2 Use of cranes and lifting beams

Loading operations may have significant impact on the vessels stability. The vertical centre of gravity will rise and be displaced in the direction of the crane. An important issue with respect to stability during loading operations is the position of the crane. The load will affect the stability with a moment arm equal the distance from VCG and to the top of the crane where the wire is suspended. The effect on the stability when the crane carries the full load of an item will be same as if the item is hanging at the top of the crane. This means that the vertical position of the item is irrelevant as long as the crane carries the full weight. Below is a vessels GZ-curve during a crane lifting operations shown.

Before lifting starts, the vessel has good stability with a large area below the GZ-curve.

The figure shows the situation when the crane carries the full load while it is positioned at the ship’s side.

Notice that the maximum righting arm is significantly reduced.

197

This is almost the same situations as shown above. The crane is now positioned at the ships centre line. There is no heeling present. However, the ships righting arm is still reduced due to the high centre of gravity.

The weight of the load is now carried by the ship structure approximately at the ships centre of gravity.

The GZ-curve is now back to where we started.

The centre of gravity will be lowered if the load is positioned below the previous centre of gravity and vice versa if the load is placed above the centre of gravity.

8.6.3 Free surface effect

The unfavourable effects that partly filled tanks have on the ships stability is called the free surface effect. All loads with liquid properties will to some degree displace to the side which the vessel is heeling. The loads’ centre of gravity (which could be fuel, fresh water, ballast etc.) moves with the vessels motions. To simplify this, the free surface effect is treated as an elevation of the centre of gravity. The most important parameter, when assessing the free surface effect is the breadth of the tank or the space where the liquid is located.

198

The vessels cargo space and bunker tanks are completely full.

This results in a low centre of gravity and thereby a large area under the GZ-curve. The range of the stability and the maximum righting arm is satisfying.

Now there is a free surface present in the cargo space. The common centre of gravity of the vessel is still elevated though the centre of gravity of the load is lower.

This is due to the free surface effect.

The centre of gravity of the vessel will always be raised when the vessel starts to consume fuel from full bunkers tank, no matter where the tanks are placed in the vessel. This is due to the free surface effect.

8.6.4 Roll reduction tank

The purpose of the roll reduction tank is to make it more comfortable to be onboard the vessel by reducing the vessels stiffness. As explained earlier, reduced stiffness will always result in a degraded stability. The roll reduction tank has a large free surface which creates a corresponding free surface effect and thereby gives the contribution to degrading stability. It's therefore misleading to speak of the roll reduction tank as a "stability tank".

199

8.6.5 Icing

The effect of icing is normally that the centre of gravity is moved up and sideways, in addition to decreased freeboard. Stability calculations for vessel with icing has to be carried out if the vessel likely will operate in waters where icing conditions may occur. The calculations may result in various loading limitations as for example: required drainage of roll reduction tank, extra water ballast or reduced loading capability under icing conditions. However, the crew should always show attention to all signs which may indicate increased likelihood of ice formation and strive to prevent icing to occur.

As a general rule, icing may occur if the air temperature is below -2C. Low temperatures, high wind velocity and sea spray are all factors which contributes to increasing risk of ice formation. A change of speed and course may reduce or even avoid ice formations. Ice does not form on smooth surfaces. It's therefore recommend to cover ship equipment on deck with tarpaulin.

8.6.6 Flooding

The vessel design determines whether the vessel in loaded condition will have sufficient area below the GZ-curve, and thereby good stability capabilities or not. However, these properties may be irrelevant if the vessel starts to take in water. A vessel with an open side hatch is flooded as soon as the hatch reaches sea level. The shape of the GZ-curve will be the same, but it is ended at heel angle which the hatch reaches sea level. The stability will be lost for all other heel angles after flooding has occurred. A large area under the GZ-curve may be of no use if flooding already has started.

Heeling of approximately 35, the righting arm is 0.57, and the vessel will recover immediately

200

The vessel has no righting arm since the side hatch is left open.

There is a great risk of capsizing which may ultimately lead to a total loss.

It is important to keep hatches and doors which can lead to flooding weathertightly closed, especially in harsh weather. If there’s a rule to keep the vessel watertight, the vessel’s safety may be increased significantly.

8.6.7 Reserve of buoyancy

A closed superstructure will lead to a large increase in stability performances. The area below the GZ-curve, the range of the stability and the maximum righting arm are increased.

A large watertight deck house contributes to good stability

201

The same vessel is here shown without a deck house. The range of stability is reduced and the vessel’s stability at large angles is reduced.

8.6.8 Change in draught

A vessel will often roll slower when it floats at a larger draught. Somebody may think that slow rolling indicates good stability, while in reality it’s a sign of the opposite. Increased draught may be interpreted as something which increase the stability of the vessel if the centre of gravity remains at the same position. However, this is not the situation. A reduction in draught will result in reductions of all the four important stability parameters (max GZ, width of the GZ-curve, area below the GZ-curve and the GM). The effect of overloading of the vessel is comparable to effect of lost reserve buoyancy.

Large freeboard implies good stability

202

Increased draught and reduced freeboard reduce stability. Righting arm is reduced and therefore the area below the curve is reduced.

8.6.9 Change in trim

A small heel which normally isn't any problem can be dangerous if the vessel is loaded more aft than normal, or if the only fuel and fresh water left is positioned astern in the vessel. A trim too large will increase the risk of flooding through hatches or other openings in the hull. A trim forward can also be dangerous for a vessel with a flat-bottomed stern region, low bow height or with little or none rake of keel. The vessels stability may suffer a sudden reduction if the stern of a flat-bottomed vessel is lifted above the sea, as may happen in following waves. Low bow height increases the risk of getting large amounts of water on deck. This water will have a high centre of gravity and as a result the vessel may trim forward with its nose down into a wave. The sum of these events lead to reduced stability. The vessel may be hard to manoeuvre if the vessel’s forward trim is combined with little rake of keel. The area below the GZ-curve will be reduced to some extent if the vessel is trimmed astern due to reduction of max GZ. The stability range is slightly increased, though total stability is reduced.

203

The vessel has no trim and thereby good stability

If the vessel is trimmed astern, the righting arm may be reduced over the stability range and therefore reduce the area below the curve.

8.6.10 Water on deck

Accumulation of water on deck should always be avoided during normal operation of the vessel.

The vessel is in even condition with good overall stability

204

Water on deck. The vessels centre of gravity is raised and the draught is increased. The free surface effect which occurs will contribute to additional degraded stability.

The result is a significantly reduced righting arm (max GZ), small range of stability and a corresponding reduced area below the curve. The vessel will have a reduced ability to withstand wind and waves. Heeling angles larger

than 40 degree will result in capsizing if the water isn't drained. Measures to avoid water on deck is to reduce trim, decrease draught, increase the area of the drainage ports or change speed and course.

8.6.11 Following seas

High speeds in following seas can lead to "burying" the stern in waves and therefore reducing the vessel’s stability. In the case of vessels with marginal stability, this can lead to capsizing.

Vessel with good stability in calm sea

205

A large part of the hull which normally is submerged will be kept out of the water if the wave length (distance for one wave top to the next) is twice as long as the vessel itself and has the same speed as the vessel. Under these circumstances only a fraction of the hull will maintain its stability. The result will be a major reduction in the area under the GZ-curve. The situation will escalate if the vessel has a forward trim.

The vessel surfs on a wave. You may notice the reduction of area below the GZ, max GZ and the stability range. The reduction is dependent on hull geometry.

The speed may be reduced, or the course changed to avoid problems with following waves.

8.6.12 Towing

The vessel which is towing may experience heeling if the towing object is drifting out to a side. The heel will be dependent of the following variables.

• Direct transverse force from object being towed.

• The angle of towing line with respect to the longitudinal direction.

• The towing vessel will experience a heeling moment if the vessel is dragged transversely because of towing. This is due to drag forces along the hull.

• All use of thrusters or conventional propellers with rudders to align the drag, introduces the risk of a heeling moment in the same direction as the transverse force from the drag.

All deck load onboard the towing vessel has to be adequately secured against displacement during towing. All loads are to be positioned in such a way that does not conflict with the towing arrangement and the crew’s safety. The towing line should not be allowed to displace. The towing arrangement should be equipped with a quick release mechanism which can be operated from different positions. The mechanism is to be designed not to compromise the crew’s safety in case of rupture of towing line or quick release. The towing gear should be mounted as low as possible to improve the vessels stability during towing operations. However, the vessel which performs the towing operation will always reduce its manoeuvring capabilities.

206

8.6.13 Anchor handling

A vessel which is performing anchor handling operations may experience large aft trim angles and low freeboard on the stern. Typical factors influencing the trim and stability are:

• Weight of anchor

• Amount of consumables and fuel oil on board

• Amount of ballast

• Weight and position of deck cargo

• Use of propulsion Care should be taken in order to avoid the chain from slipping over to the side, which can cause capsizing. The chain should therefore be secured with towing pins or other arrangements in order to avoid such incidents. It is important to ensure that the winch emergency release function is operative.

207

9 SAMPLE STABILITY CONDITION

9.1 Obtaining draught and trim

Using hydrostatic data for zero trim, one can interpolate for a specific displacement and obtain values for draught, LCB and MCT. For calculation of trim and draught based on a loading condition calculation, the following data are required:

• Longitudinal centre of gravity of the vessel, LCG;

• Longitudinal centre of buoyancy, LCB;

• Displacement, DISP;

• Moment to change trim, MCT

• Longitudinal centre of flotation, LCF

LCB, LCF, and MCT are taken from the hydrostatic tables (for trim = 0m) corresponding to the actual displacement. Trim is calculated as below. If the LCB is forward of the LCG the trim is by the stern and if the LCB is aft of the LCG the trim is by the head (bow). It is to be noted that the reference length used to calculate the trim is the length between perpendiculars (LBP).

𝑇𝑅𝐼𝑀 =𝐷𝑖𝑠𝑝𝑙𝑎𝑐𝑒𝑚𝑒𝑛𝑡 ∙ (𝐿𝐶𝐵 − 𝐿𝐶𝐺)

𝑀𝑇𝑐𝑚 ∙ 100 [𝑚]

Figure 9 - Trim calculation

If the resulted trim exceeds the steps set out in the hydrostatics tables (e.g. 0.5 m aft or 0.5 m fwd), the nearest hydrostatics table should be used.

208

From the above figure, the draught at the aft and forward perpendiculars can be calculated with the following formulae:

𝑇aft = 𝑇 − (𝑑𝐴𝑓𝑡 + 𝐿𝐶𝐹) ∙ tan(𝜑)

𝑇fwd = 𝑇 + (𝑑𝐹𝑤𝑑 − 𝐿𝐶𝐹) ∙ tan(𝜑)

Where 𝑇aft and 𝑇fwd are the draughts at the aft and forward perpendiculars and φ is the angle of trim.

9.2 Example for use of the maximum VCG curve This example shows how to carry out calculations for a specific loading condition. The example also shows how the user can verify the stability in every loading condition with the help of the VCG Max Curves.

Notes on calculations:

• To obtain the values of vertical moment (V-MNT) in Column 3 you multiply the values of column 1 and

column 4.

• To obtain the values of longitudinal moment (L-MNT) in Column 5 you multiply the values of column 1 and column 4.

• To obtain the values of transverse moment (T-MNT) in Column 7 you multiply the values of column 1 and column 6.

• All values in Column 1 are then added to obtain “Total (no FSCorr.)”. This procedure is repeated for Columns 3, 5, 7 and 8.

• Dividing the sum in Column 3 with sum in Column 1 you will get VCG total before correction for free surface moment (FSM).

• Dividing the sum in Column 5 with sum in Column 1 you will get the LCG total.

• Dividing the sum in Column 7 with sum in Column 1 you will get the TCG total.

• Correction for free surface moment is obtained by dividing the sum of Column 8 with the vessel’s actual displacement from Column 1. This value is added to the VCG total to find the overall VCG pertinent to this loading condition.

A quick stability assessment can be performed by determining the displacement and VCG of a given loadcase and plotting it on the Max. VCG curve. For positive stability the point should be positioned below the curve corresponding to a certain trim.

The point is under the Max. VCG curve, therefore stability is satisfactory for all trim values.
