Question

Is there a permanent or site-specific approval from DNV with regard to waves in deck for survival and operation condition?​

Answer

A permanent approval is verified by class DNVGL. This is captured by, Design Criteria Operational Limitations, doc no L4-MODU-DSY-E-MA-302, rev3, dated 15.11.2021.​

The procedure captures any limitations issued related to DNVGL-OTG-13 and 14.​
