PreambleThis Recommended Practice (RP) outlines the general best practices that lead to effective Testing andcommissioning of marine and industrial systems onboard mobile Offshore units in newbuilding Projects . Forconvenience, an extract of all DNV rules related to Testing and commissioning of marine and industrial systemshave been included in this document.

5 It should be noted that for more accurate applicable statutory and classrequirements related to Testing and commissioning , applicable versions of the statutory and class rules asspecified in the contract shall be referred to. System categorizations included in the appendix are general innature 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 drillingunits with the intention to include requirements related to other object types at a later stage. GeneralDNV has recognized that the technical complexity of modern Offshore Installations is increasing due tosystems becoming more complex, more automated and more tightly integrated.

6 This evolution providesdesigners, shipyards, owners and other involved parties challenges in the management of Testing andcommissioning equipment and systems onboard Offshore units ObjectiveThis RP outlines recommended work processes for the Testing and commissioning activities on offshorenewbuild units. This document shall be read as a guide to Testing and commissioning equipment ad systemsonboard Offshore Units. The document will help users in preparing or carrying out witnessing of Testing andcommissioning activities to satisfy the requirements of Classification and applicable statutory regulations whereDNV has delegation from such authorities. It should be noted that final acceptance of commissioning is theowner s Scope and ApplicationThis guide is applicable to Testing and commissioning activities onboard classed Mobile Offshore Units ,Drilling, Accommodation and FPSO Structure of this documentThis document contains a general overview of Testing and commissioning activities together with samples of typical contents oftesting and commissioning procedures including the ones for integration Testing and commissioning Extract of applicable DNV Service Specifications and DNV standards related to preparation, Testing andcommissioning of various marine, utility and industrial systems Categorization of marine.

7 Utility and industrial systems that can be used to decide on the extent ofinvolvement from various RP can be used as a check list for reviewing commissioning procedures to assist preparation ofrequirements related to class and applicable statutory How to use this documentThe main function of the RP is to ensure that the commissioning procedures contain all the relevant informationrequired by the applicable DNV Service Specifications and DNV Offshore the commissioning procedures are reviewed against this document, they should contain all the requiredinformation to ensure compliance with the various Offshore standards thus ensuring that Testing andcommissioning activities are fully in compliance with the required Classification ReferencesInformation and requirements provided in this RP are extracted from the following DNV ServiceSpecifications, Offshore Standards and Ship Rules.

10 March commissioning Process and Definition of Various Stages Page 72. commissioning Process and Definition of Various StagesCommissioning of an Offshore unit is a time consuming and complex process. A structured approach is anecessity for a successful commissioning phase of the newbuilding Projects . While the requirements for thetesting and commissioning are clearly specified in various applicable DNV standards, how exactly thecommissioning activities should be carried out is largely left to the Builder/Owners of the mobile offshoreunits. For instance, there will be dependencies between the different packages. It is, however, a DNVrequirement to see that the Testing requirements mentioned in our rules are carried out during is often required by DNV Offshore standards that the equipment is to be tested in as installed condition.
