PROJECT: DEEPSEA ATLANTIC – SPS CLASS RENEWAL

CLIENT: ODFJELL DRILLING

Otech Marine Services was contracted to perform a large amount of works during the 5 year class renewal of the Semi Submersible Rig Deepsea Atlantic.

The challenge was to affect the Rig with the minimum amount of downtime. All required works needed to be completed within the 14 days yard stay including inspections, overhaul of overboard valves, replacement of two azimuth thrusters and design and production of sea chest covers and double barriers.

The project was one of the most compact and intense inshore diving projects ever completed in Norway counting more than 20 000 minutes of bottom time during its short duration of 12 days, and a real test of how efficient it is possible to perform a diving operation and the importance of high standard equipment.

Our LDC vessel, designed for offshore operations, supported the crew during the operations, keeping our quality and safety standard.
