Objectives

The objectives of this standard are to:

— provide an internationally acceptable standard for design of ship-shaped Drilling and Well Service Units

— serve as a technical reference document in contractual matters between purchaser and manufacturer

— serve as a guideline for designers, purchaser, contractors and regulators

— specify procedures and requirements for units subject to DNV classification services

— base the design of the hull and topside on the same principles and methodology for all transit and operational scenarios

— provide, as far as possible, consistent loads for both top-side and hull design.

The hull strength may be assessed according to DNV Rules for Classification of Ships Pt.3 Ch.1 for all transit and operational conditions.
