BSEE requirements:

The other regulatory agency that share jurisdiction on OCS activities is BSEE, which has its own requirements.

BSEE requirements that are related to structures, mooring and foundation are covered under a platform veri? ca- tion program as de? ned in 30 CFR 250 sub-chapter I. The veri? cation program needs to be performed by a nominated

CVA (DNV GL has such authorization).

The CVAs responsibilities during design, fabrication and installation are de? ned in 250.915, 250.916, and 250.917.

Therefore, for these units with DNV GL and plant maintenance class including the US notation, most of the BSEE requirement for the structural integrity and stability inclusive of moor- ing, turret and hull interfaces will be satis- ? ed.
