DNV DNVGL-OS-C102 PDF

Scope and applications

This standard covers the following ship-shaped units constructed in steel:

— production and storage (FPSO/FLNG/FSO)

— drilling

— well intervention

for the following structural items:

— material selection and inspection principles

— design conditions and design loads

— hull strength assessment

— fatigue requirements

— topside structure

— topside and turret interface to hull structure

— unit specific requirements

— procedures and requirements for units subject to DNV GL classification services.

Serviceability (SLS) condition is not covered in this standard.

Strength requirements are given for restricted and non-restricted transit and operation. Units without any restrictions may operate world wide, except in Polar areas. For operation in Polar areas additional requirements associated with such operation shall be complied with.

For novel designs or unproven applications where limited experience is available, global FE-analyses and model tests may be required to demonstrate the overall strength and fatigue capacity.

In case of conflicts between requirements given in this standard and other DNV GL documents, the requirements given in this standard prevail.

For application of this standard as technical basis for classification see Ch.3 Sec.1.

Flag and shelf state requirements are not covered by this standard.

Guidance note:

Governmental regulations may include requirements in excess of the provisions of this standard depending on the type, location and intended service of the offshore unit or installation.
