Scope of Classification

New Constructions

Classification covers the mobile offshore unit's or the fixed offshore installation's hull/structure and machinery including electrical installations as well as special equipment and installations as far as agreed in the building specification between the prospective owner and the building yard. 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 use on purpose.

Hull/structures, machinery and equipment determining the type of mobile offshore unit or fixed offshore installation are subject to examination within the scope of Classification, in accordance with the Character of Classification and affixed Class Notations. Other systems and components may be included in the Classification and/or Certification procedure upon request of the prospective mobile offshore unit's Owner or the fixed offshore installation's Owner, the building yard or other subcontractors.

Upon completion of construction and trials, the Class Certificate(s) will be issued and will be kept on board, unless another location is agreed. The Certificates have a defined period of validity (Class Period), and may be renewed after prescribed thorough surveys, see Sections 3 and 5.
