The Holstein field is located 200-miles (322-kilometers) south of New Orleans, La. in 4,300-feet of water (1,311-meters) on Green Canyon Block 645.

Devil’s Tower Spar supports 15 subsea wells with vertical access required for response. Thus the emergency response planning requires both operational and technical expertise.

Delmar’s experience in the field enabled them to apply a real world scenario for 3rd party access and well shut-in. The provided engineering and operational planning services for hull offset enabled the necessary direct vertical access for subsea well intervention.
