6 SECTION 1 INTRODUCTION 1.1 Preamble This 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 General DNV 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 and systems onboard offshore units successfully. 1.3 Objective This 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 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 application This guide is applicable to testing and commissioning activities onboard classed mobile offshore units e.g., drilling, accommodation and FPSOs. 1.5 Structure of this document This 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 document The 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.

9 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 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 design When 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

10 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 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, piping, instrumentation, cabling, electrical, 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 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 should be verified during mechanical completion stage so that there are no surprises before commencing precommissioning, 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

11 SECTION 3 PRE-COMMISSIONING 3.1 Introduction Pre-commissioning is the stage before commissioning which involves the verification of functional operability of the part or full systems. This stage of testing requires energising of 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 /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. Precommissioning would typically include: Loop testing. Motor no load runs. Equipment final alignments. 3.2 Commissioning The 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 /system commissioning will consist of: Functional testing of systems by start-up priority. Testing of ESD/PSD and F&G. Load tests and other performance testing. In the commissioning phase it will be verified that the installed and system are working as intended and that the rule requirements for the various /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 is not dismantled or modified after testing and commissioning of the /system is completed. Once the /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 testing Integration testing is a collective term for testing and commissioning of more than one system (a collection of systems, sub-systems and 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 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

12 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, lifesaving 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, 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 Delivery Depending 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 up Hook 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 Operation Once 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.

15 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 Sub System List).

16 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 associated with commissioning is adequate; there is adequate control of temporary commissioning aids e.g. E&I hardwired links, isolations, spades in process lines.
