SECTION 1GENERAL

Electronic binding versions

As of October 2010, we are introducing two new DNV service document types to be used for services that are

not limited to offshore and/or not to be considered as DNV Rules for classification of Ships or HSLC/NSC. Thedocuments have been named; DNV Service Specifications (DSS) and DNV Standards (DS).

Additionally, as of October 2010 all DNV service documents are primarily published electronically. The elec-tronic pdf versions of the documents found through http://www.dnv.com are the officially binding versions.

In order to initiate and ensure a practical transition from the OSS/OS to DSS/DS scheme for relevant documentsand “print” scheme to the “electronic” scheme the following has been done:,

All documents that should be transferred without further change in content to the new document types DSS or DS and those having incorporated amendments and corrections more recent than the date of the latest printedissue, have been renamed as relevant and given the date October 2010.

Except the already incorporated amendments and corrections, no other changes have been made to the documents.

The applicable documents are shown in the table below.

Update Scheme

The update scheme of the documents is as follows:

1) Whenever revised, or undergoing significant editorial changes, a document will be given a new edition dateand the main changes will be described on Page 3 of that document. The corresponding Adobe PDF filewill be made available through http://www.dnv.com/resources/rules_standards/ and the date of the “Cur-rent edition” column of Table 1 in Sec.2 will be updated.

2) If, at a later date, the need arises for insignificant editorial corrections to the document, the electronic filewill be updated, but the edition date will be retained. However, a new Adobe PDF file will be generatedand made available through http://www.dnv.com/resources/rules_standards/. The date of the PDF file willappear in the “Editorial corrections” column of Table 1 in Sec.2.

Discontinued updating of the “Amendments and Corrections” document

As a result of moving away from the “Print” scheme there is no longer need for a separate “Amendments andcorrections” document which intention was to supply buyers of printed documents with a detailed view of “amendments” to the documents applicable after issued in print.

The electronic PDF files are now the officially binding versions and will always be kept current and download-able.

Readers of documents are encouraged to regularly check for updates in order to ensure that they hold the cur-

rent updated versions.

SECTION 3SUMMARY OF CHANGES

A. Changes to DNV Service Specifications

DNV Service Specifications – Main changes Document number Document title Main changes

DNV-OSS-101 Rules for Classification

of Offshore Drilling

and Support Units

— Well Intervention Units:

The current DNV-OSS-101 does not take into account the needs of the indus-try. Well Intervention Unit service notation has therefore been split in two,and one of the service notations will be voluntary instead of mandatory as it istoday.

The WELL notation has been split in two - where the WELL-1 notation willnot require the owner to certify the sub sea equipment (RS1).

— ISDS:

New voluntary class notations for Independent Software Dependent SystemIntegration (ISDS-1 to 3) introduced.

— Hull PMS:

Hull PMS (planned maintenance system) introduced as an optional alternativesurvey arrangement- also for offshore units.

— In-service Inspection of structures:

The inspection scope for column-stabilised units has been updated with in-creased emphasis on renewal survey, and corresponding reduced externalscope for intermediate surveys.

— Provisions for Ageing Units:

Alternative to increased inspection due to age has been introduced, allowingfor inspection based on the actual condition rather than age in order to main-tain the required safety level.

DNV-OSS-102 Rules for Classification

of Floating Production,

Storage and Loading Units

— ISDS:

New voluntary class notations for Independent Software Dependent SystemIntegration (ISDS -1 to 3) have been introduced.

— Hull PMS:Hull PMS (Planned Maintenance System) has been introduced as an optionalalternative survey arrangement also for offshore units.

— In-service Inspection of structures:

— The inspection scope for column-stabilised units has been updated withincreased emphasis on renewal survey, and corresponding reduced exter-nal scope for intermediate surveys.

— Revised scope for boiler survey: Aligned with new IACS unified require-ments

— General update of references and editorial improvements: Based on expe-rience feed-back from users.

DNV-DSS-314 Verification of Hydrocar- bon Refining and Petro-chemical Facilities

This service specification; DSS-314: “Verification of Hydrocarbon Refining andPetrochemical Facilities” replaces the previous version of the document with shortname; DNV-OSS-314. There are no changes in content, only how the document isreferred to, as OSS now will be used for Service Specifications intended for Off-shore use.

DNV-DSS-315 Verification of OnshoreLNG and Gas Facilities

This service specification; DSS-315: “Verification of Onshore LNG and Gas Facil-ities” replaces the previous version of the document with short name; DNV-OSS-315. There are no changes in content, only how the document is referred to, as OSSnow will be used for Service Specifications intended for Offshore use.

requirements to long term mooring and. mobile mooring. The scope of testingfor mobile mooring is brought in line with ISO 18962, whilst for long termmoorings the principle of application of specific mooring systems perform-ance is reinforced.

— Rules for hardware (thimbles) have been clarified. — Testing methods, which are subject to approval, have been removed from Ch.2Sec.3.

— The previous Appendixes A, B, C and D on ‘Fibre rope stretch and stiffness’,‘Measuring and Expressing the Rope Change-in-Length Properties’, ‘Change-in-length test methods for long-term mooring’ and ‘Quality review report’have been removed.

— The term ‘soil barrier’ is replaced by ‘filter’, as this is the commonly used termin other standards.

— Added a new Appendix A containing ‘scope of survey’ for fibre-rope production.
