involve a whole chapter, section or sub-section, normally only the title will be in red colour.

Main changes July 2015• GeneralThe revision of this document is part of the DNV GL merger, updating the previous DNV recommended practice into a DNV GL format including updated nomenclature and document reference numbering, e.g.:

— DNV replaced by DNV GL.— DNV-RP-A204 to DNVGL-CG-0169 etc.

A complete listing with updated reference numbers can be found on DNV GL's homepage on internet.

To complete your understanding, observe that the entire DNV GL update process will be implemented sequentially. Hence, for some of the references, still the legacy DNV documents apply and are explicitly indicated as such, e.g.: Rules for Ships has become DNV Rules for Ships.

In addition to the above stated main changes, editorial corrections may have been made.

SECTION 1 GENERAL
1.1 Preamble This is a classification guide only for a typical drillship and should be used no more than as an example to prepare a project specific quality survey plan (QSP) that addresses all the requirements related to a specific project. A project specific quality survey plan with agreed extent of participation from DNV GL shall be submitted by the builder/owner (as applicable) for approval by DNV GL prior to commencement of activities.

This classification guide contains requirements obtained from IACS unified requirements, Z23 Hull Survey for New Constructions. For the convenience of users, various cross references to relevant rules and guidelines are provided in addition to IACS documents.

IACS unified requirements; Z23 Hull Survey for New Constructions is available from www.IACS.co.uk. This guide also incorporates relevant requirements of IACS UI SC234, UI LL76 and UI MPC96 regarding initial statutory surveys at new construction. Updates to IACS Z23 are also incorporated.

1.2 Objective The objectives of this guide are to ascertain various activities that are necessary for the classification of a unit, to identify Customer’s, DNV GL’s and various standards and procedures that are applicable to those activities, and to define the extent of involvement by the customer and DNV GL.

1.3 ScopeThe scope is defined in the contract between the customer and DNV GL but typically covers the requirements of applicable rules related to main class, statutory and additional class notation. The scope of the typical quality survey plan should include all the activities of the new building project as much as possible, but the contents of QSP shall not be considered as covering the detailed scope as specified in the contract.

Description of principles and procedures for DNV GL’s services related to newbuilding projects are described in the applicable DNV GL rules for classification: Offshore units e.g., DNVGL-RU-OU-0101 Offshore drilling and support units, DNVGL-RU-OU-0102 Floating production, storage and loading units, etc.

SECTION 2 APPLICATIONS
2.1 GeneralUsing this as a model document, a project specific quality survey plan (QSP) that clearly identifies the agreed level of participation by the Society shall be prepared by the Customer and accepted by the Society for use in all new building classification projects.

2.2 Certification of equipment and materialsThis document does not cover the certification of equipment and materials.

Evidence of acceptance for such items shall be provided by the client by way of accompanying documentation from a class surveyor at manufacturer’s or other applicable location and verified at the Customer’s location.

2.3 Locations of construction This document applies to the offshore construction activities at any of the following:

i) customer’s construction facilitiesii) subcontractors at the customer’s construction facilitiesiii) subcontractors at their own facilities or at other remote locations.


DNV GL AS

SECTION 3 REVIEW OF THE CONSTRUCTION FACILITY
DNV GL is to familiarize itself with the Customer’s production facilities, management processes, and safety procedures for consideration in determining the contents and application of Table 4-1. This familiarization shall take place prior to starting any fabrication or construction. Such familiarization will take place under the following circumstances:

i) where DNV GL has no recent experience at the construction facility (typically after a lapse of one year)or when a significant new infrastructure to the facility has been added

ii) where there has been a significant management or personnel restructuring, having an impact on theship or offshore construction processes or,

iii) where the builder contracts to construct a vessel of a different type or substantially different in design.

In order to assess compliance with specified rules, standards and regulations, the Society may require additional documentation and carry out an assessment of yard’s processes, systems, and personnel related to the classification projects. The results of the assessment should be used as a basis to decide on the extent of the involvement of surveyors of the Society. The extent of the classification Society’s involvement for the site survey activities shall be clearly reflected in Table 4-1 in this document.

Where DNV GL has no recent experience with new building activities at the builder’s construction facility or its subcontractors and/or when significant new infrastructure has been added, DNV GL may initiate an MPQA and evaluate the Customer’s QA/QC-performance and set the initial survey scope on basis of the MPQA rating methodology.


DNV GL AS

SECTION 4 NEW BUILDING SURVEY PLANNING
4.1 Kick-off meeting Prior to commencement of any new building project, the Customer and DNV GL are to discuss at a kick-off meeting the survey activity items listed in Table 4-1. The purpose is to agree how the list of specific activities shown in the table is sufficiently comprehensive, to be adjusted, if necessary and to be addressed.

A record of the meeting is to be made, based upon the contents of the Table, (the table can be used as the record with comments made inserted in the appropriate column). The Customer may be asked to agree to undertake ad hoc investigations during construction where areas of concern arise. DNV GL is to be kept informed of the progress of any investigation. Whenever an investigation is undertaken and, if warranted by the severity of the problem, the Customer should suspend relevant construction activities until counteractive measures are satisfactorily implemented, reviewed and accepted by the Society.

4.2 Quality standardsConstruction quality standards for the hull structure, piping, electrical, HVAC and other disciplines during new building project are to be properly listed in this document, reviewed and agreed during the kick-off meeting.

4.3 Survey extent It shall be underscored that the QSP table is not exhaustive, and in cases where the QSP is incomplete and/or not necessarily covering all survey aspects, it shall be the prerogative of DNV GL to require such activities/items added.

The QSP only covers survey activities and does not cover the technical interpretations of the statutory requirements or approval of plans, designs and manuals required by the regulations.
