DNV DNVGL-RU-NAVAL PART 1 CHAPTER 2 PDF

The Rules for Classification and Surveys of Naval Shipscover the classification of naval surface ships and naval submarines as defined in [2] and in Ch.3 Sec.3 and Ch.3 Sec.4.

Classification covers the ship's hull and machinery including electrical installations as well as special equipment and installations as far as agreed in the building specification between the naval administration and the shipyard. Classification aims primarily at ensuring reliability of the hull structure and machinery systems on board resulting in an adequate level of safety of personnel and environmental protection.

However, Classification is not intended to ensure the effectiveness of the intended missions. Structures, machinery and equipment determining the type of ship are subject to examination within the scope of Classification, in accordance with the character of classification and affixed notations.

Other systems and components may be included in the Classification and/or certification procedure upon request of the naval administration.

Particular systems and components for military use (esp. weapons and their sensors) are normally exempted from Classification, depending also on the indication of the naval administration and on legal or contractual restrictions. However, influences from such systems possibly affecting safety of the ship as their platform (e.g. static and dynamic loads, explosion or fire hazards, power supply, etc.) shall be taken into account in the design appraisal for classification.

Design appraisal within the classification procedure will normally include the review or recalculation of stability investigations. This requires the relevant information, on (e.g. combat-related) damages to be taken into account, to be submitted by the naval administration.

It is assumed that all parties involved in the planning and design, materials and components production and installation have the professional qualifications required and/or suitable facilities/equipment for fabrication. This will normally be established or confirmed by means of a certified quality assurance management system in accordance with ISO 9000 series, AQAP or equivalent.
