- SECTION 1 INTRODUCTION
1.1 PreambleThis class guideline (CG) outlines the general best
practices that lead to effective testing and commissioning of
marine and industrial systems onboard mobile offshore units in
newbuilding projects. For convenience, an extract of all DNV GL
rules related to testing and commissioning of marine and industrial
systems have been included in this document. It should be noted
that for more accurate applicable statutory and class requirements
related to testing and commissioning, applicable versions of the
statutory and class rules as specified in the contract shall be
referred to. System categorizations included in the appendix are
general in nature and may not include all applicable systems that
are specific to particular newbuilding projects and so, this
document should be used only as a guide. This document currently
includes requirements related to drilling units with the intention
to include requirements related to other object types at a later
stage.
1.2 GeneralDNV GL has recognized that the technical complexity
of modern Offshore Installations is increasing due to systems
becoming more complex, more automated and more tightly integrated.
This evolution provides designers, shipyards, owners and other
involved parties challenges in the management of testing and
commissioning equipment and systems onboard offshore units
successfully.
1.3 ObjectiveThis CG outlines recommended work processes for the
testing and commissioning activities on offshore newbuild units.
This document shall be read as a guide to testing and commissioning
equipment and systems onboard offshore Units. The document will
help users in preparing or carrying out witnessing of testing and
commissioning activities to satisfy the requirements of
classification and applicable statutory regulations where DNV GL
has delegation from such authorities.
It should be noted that final acceptance of commissioning is the
owner's responsibility. This CG only covers class and statutory
related activities.
1.4 Scope and applicationThis guide is applicable to testing and
commissioning activities onboard classed mobile offshore units
e.g., drilling, accommodation and FPSOs.
1.5 Structure of this documentThis document contains:
— A general overview of testing and commissioning activities
together with samples of typical contents of testing and
commissioning procedures including the ones for integration testing
and commissioning.
— Extract of applicable DNV GL rules for classification of
offshore units (rules for offshore units) and DNV GL offshore
standards related to preparation, testing and commissioning of
various marine, utility and industrial systems.
— Categorization of marine, utility and industrial systems that
can be used to decide on the extent of involvement from various
stakeholders.
This CG can be used as a check list for reviewing commissioning
procedures to assist preparation of requirements related to class
and applicable statutory regulations.
1.6 How to use this documentThe main function of this CG is to
ensure that the commissioning procedures contain all the relevant
information required by the applicable DNV GL rules for offshore
units and DNV GL offshore standards.
If the commissioning procedures are reviewed against this
document, they should contain all the required information to
ensure compliance with the various offshore standards thus ensuring
that testing and commissioning activities are fully in compliance
with the required classification requirements.

- SECTION 2 COMMISSIONING PROCESS AND DEFINITION OF
VARIOUS STAGES
2.1 Introduction
Commissioning of an offshore unit is a time consuming and
complex process. A structured approach is a necessity for a
successful commissioning phase of the newbuilding projects. While
the requirements for the testing and commissioning are clearly
specified in various applicable DNV GL standards, how exactly the
commissioning activities should be carried out is largely left to
the Builder/Owners of the mobile offshore units. For instance,
there will be dependencies between the different packages. It is,
however, a DNV GL requirement to see that the testing requirements
mentioned in our rules are carried out during commissioning. It is
often required by DNV GL offshore standards that the equipment is
to be tested in “as installed” condition. So, though similar tests
have already been carried out during a factory acceptance test
(FAT), a new test in installed condition would be required. A
typical example could be the offshore cranes. They will probably be
overload tested during FAT, but they will still be necessary to
overload test in installed condition.
Before commissioning starts the responsible DNV GL surveyor and
all stakeholders involved in preparing and carrying out the testing
and commissioning should also have an idea as to what activities
are considered most important to DNV GL and also what activities
are not within the DNV scope. During commissioning it is also
important to be aware that the owner’s and the yard’s viewpoint as
to what is DNV GL’s scope of work may not be in harmony with the
scope required by the DNV GL Offshore standards. It is also
important to recognize that owner/yard may have additional
requirements e.g., related to performance or additional
functionality, that may be over and above the classification
requirements of DNV GL.
2.2 Detailed designWhen entering into the final stages of any
project, the detailed design is expected to be fully completed,
reviewed and approved. Failure to complete the design in a
satisfactory manner may undermine already completed testing and
commissioning, especially comments that may result in redesigning
component or systems. Any duplication in redoing testing and
commissioning is not very efficient and will result in loss of
valuable time and additional cost. The preferred solution would be
to have the design engineers available during the commissioning
stages. The design engineer can then confirm completion of the
design activities and advise what needs to be rectified, redesigned
and followed up.
Class guideline, DNVGL-CG-0170 – Edition July 2015 Page 9
DNV GL AS
- 2.3 Mechanical completion
For most offshore projects mechanical completion (MC) is
considered a natural and a logical step on the way towards proper
project completion. It is normal for the builder or system vendor
to create mechanical completion check lists for the actual
equipment or system. Only some parts of mechanical completion is
covered in the DNV Offshore standards and is thus formally DNV GL
scope of work. DNV GL generally maintain oversight of most of the
mechanical completion activities of the project through unscheduled
surveys. Where it is mandated by the quality survey plan (QSP), a
DNV GL surveyor may attend certain mechanical completion
activities. Some of the examples of such activities are:
— pressure testing of piping— installation of main
engines/alignment— cable installation / segregation of cables.
In this instruction, MC is completed when construction and
installation of equipment, piping, instrumentation, cabling,
electrical equipment, etc. have been demonstrated as physically
complete. Dynamic tests are limited to non-energised tests like
cold alignment of shafting for motors, engines and generators.
Further megger tests, flushing and drying of piping systems,
cleaning, etc. is included in this milestone. Typically, the MC
will result in a number of outstanding activities that must be
rectified before any actual pre-commissioning, testing and
commissioning can commence. Normal findings typically include
missing electrical equipment grounding, lack of proper shielding of
fuel pipes or hot surfaces, insufficient nozzle coverage for deluge
systems, etc. The evidence of the required certification of
equipment should be verified during mechanical completion stage so
that there are no surprises before commencing pre-commissioning,
testing and commissioning stages. Failure to do so may jeopardize
the safety of such activities.
Class guideline, DNVGL-CG-0170 – Edition July 2015 Page 10
DNV GL AS
- SECTION 3 PRE-COMMISSIONING
3.1 IntroductionPre-commissioning is the stage before
commissioning which involves the verification of functional
operability of the equipment part or full systems. This stage of
testing requires energising of equipment and introduction of fluids
in fluid piping systems. This is the stage where the vendor and/or
the yard are carrying out independent testing of the
equipment/system. This is a “trial and error” phase where class
normally do not attend. During review and approval of commissioning
procedures, it is important for the DNV GL surveyor to make sure
that tests required by the rules are carried out during the
commissioning phase. It may be a challenge when the tests required
by the rules are carried out during pre-commissioning but not
attended by a DNV GL surveyor. This should be highlighted during
the review of the commissioning procedures. Pre-commissioning would
typically include:
— Loop testing. — Motor no load runs. — Equipment final
alignments.
3.2 CommissioningThe phase after mechanical completion, pre
commissioning and testing is often referred to as the commissioning
phase. The “commissioning of an offshore unit” is a very wide term
and for the purpose of classification, it refers to final checks,
inspection and tests that every operational component or system
goes through to confirm operational readiness. Typically
equipment/system commissioning will consist of:
— Functional testing of systems by start-up priority.— Testing
of ESD/PSD and F&G.— Load tests and other equipment performance
testing.
In the commissioning phase it will be verified that the
installed equipment and system are working as intended and that the
rule requirements for the various equipment/system functionality
are met. The rules will have requirements for “performance”, e.g.
number of starts for starting air receivers and “functionality”,
e.g. safety functions of boilers and incinerators.
For effective commissioning, it is important that the testing
and commissioning of the different skids/packages are given the
right priority so that they happen in the right sequence/order.
Very little commissioning can be performed without the hydraulic
ring line, power system, cooling water, pneumatic systems and other
utilities being functional and working properly. Typically,
temporary arrangements should not be accepted for commissioning. It
should also be a general principle that commissioned equipment is
not dismantled or modified after testing and commissioning of the
equipment/system is completed. Once the equipment/system is tested
and commissioning is completed it is good practice to have a close
out meeting where the commissioning procedures are signed, by owner
and outstanding punch items are agreed.
3.3 Integration testingIntegration testing is a collective term
for testing and commissioning of more than one system (a collection
of systems, sub-systems and equipment packages) to ensure
compliance with project requirements. Many systems onboard are
integrated with other systems in one way or another. However, in
this context, integration testing is meant to cover the following
but not limited to:
— Complete functional testing of systems across equipment
boundaries. — Final adjustments of alarm-limits, measuring
instruments.— End to end testing of ESD/PSD and F&G.—
Integrated testing of PROD/DRILL plants.
Many of the system integration tests are often carried out
during the marine sea trial as all the relevant systems and
consumers may be required to be ready for such tests to be carried
out. The trials can also be organised e.g. with one drilling trial
and one marine sea trial.
Class guideline, DNVGL-CG-0170 – Edition July 2015 Page 11
DNV GL AS
- 3.4 Marine sea trial
The marine sea trials typically focuses on propulsion, steering
and utility systems functioning under normal operating conditions.
A prerequisite for sea trials is that the major safety systems like
fire fighting, life-saving appliances, PA/GA, HVAC, etc. are
satisfactorily commissioned ahead of sea trials. In addition, the
inclining test should be completed prior to taking the unit out on
sea trial.
Sea trials are conducted to test a vessels performance and
general seaworthiness. Testing of a vessels speed, manoeuvrability,
equipment and safety features are usually conducted during sea
trial. However, this demonstration of speed and manoeuvrability,
etc. is normally more important for a merchant vessel than an
offshore unit. A merchant vessel will typically have a contract
speed as part of the contract between the builder and the owner.
That is seldom the case for an offshore unit. The marine sea trial
will typically consist of but not limited to:
— testing of Dynamic Positioning System
— final commissioning of Ballast systems, Cooling water, Lube
oil, Fuel Oil, HVAC, Thrusters, etc.
— speed test
— crash stop
— turning test
— E0 test (Unmanned machinery space alarms)
— endurance test.
The marine sea trial is normally not relevant for fixed units or
units without propulsion.
3.5 DeliveryDepending on type of unit, the successful completion
of all testing and commissioning activities will trigger the
delivery of the unit. The level of completion will however vary
from project to project. Typically a project with a contract in
place and a long transit to the operation area, the owner may
prefer an early delivery with the intention to close some of the
outstanding items in transit. If a unit does not have a project in
place, the owner will typically aim for a higher level of
completion before they will accept the unit. Equipment subject to
class approval that is not readily commissioned in accordance with
approved testing and commissioning procedures should be identified
in the delivery documentation by issuance of relevant conditions of
class. It should be evaluated prior to delivery whether the
outstanding class and statutory systems are minor in nature and
does not affect the safety and integrity of the unit that will
allow the Class Society to issue appropriate Class and Statutory
Certificates. If critical systems e.g., fire fighting/detection,
propulsion and steering, life-saving appliances, navigational aids,
etc. are not commissioned, Class and Statutory Certificates are not
typically issued.
3.6 Hook upHook up is mostly relevant for fixed units like FPSOs
and other units that will stay on the same location for a number of
years, however some drilling units may require some testing of
systems on first location. Typically it means the hook up of risers
to the unit and preparations required prior to first oil. Many of
the vital commissioning activities for such units will have to take
place at location and cannot be completed during the construction
of the unit. Hook up is not typically included in the class scope
but if safety and integrity of the vessel is in question, Class
Society typically evaluates the status of such operation.
3.7 OperationOnce the unit is in operation, there should not be
any major outstanding class and statutory items carried over from
the newbuilding phase and procedures related to “units in
operation” requirements should be followed.

- SECTION 5 DNV GL INVOLVEMENT IN COMMISSIONING
DNV GL’s involvement in testing and commissioning is limited to
the requirements of statutory and class rules. DNV GL surveyor will
attend testing and commissioning to the extent specified in
applicable quality survey program (QSP).
Survey scope shall be categorized as follows:
— Survey Category 1 - Statutory and Essential Systems for Safety
(normally increased attendance by DNV GL).
— Survey Category 2 - Main Systems / Functionally Important (For
Main and Additional Class Notations, extent is based on the yard’s
experience and the effectiveness of Yard’s QA/QC system).
— Survey Category 3 – Normally limited or no attendance required
by surveyor.
The tables attached in the following appendices detail the
“survey categorization during Mechanical Completion and
Commissioning of Marine and Drilling Systems” (based on Project
System / Sub System List).

- SECTION 6 SAFETY, HEALTH AND ENVIRONMENT
It is important to note that commissioning activities may
introduce additional hazards to the process that may not have been
considered in the design phase i.e. the use of alternative media
for testing in the absence of hydrocarbons. When evaluating extent
of checks and tests the philosophy of Primum non nocere or first do
no harm should be considered.
It should also be noted that the commissioning activities
themselves may also introduce additional risks and hazards into the
workplace. Prior to start of any commissioning the relevant safe
job analysis should be performed where relevant dangers are
highlighted and sufficient efforts are taken to minimize the
risks.
It is important to ensure responsibilities are clearly defined
and recognised; that there are suitable and sufficient instructions
e.g. procedures, method statements, workpacks; whether control and
supervision of staff and contractors is adequate; whether
arrangements for calibration of any test equipment associated with
commissioning is adequate; there is adequate control of temporary
commissioning aids e.g. E&I hardwired links, isolations, spades
in process lines.
