SPS – Class renewal survey


In 2014 Otech Marine Services was given the contract to perform a large amount of works during the 5 year class renewal of the Semi Submersible Rig Deepsea Atlantic.


Added in the mix was a challenge to perform all required works in 14 days including all 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 in Norway counting more than 20 000 minutes of bottom time during its short duration of 12 days.


For the project team the project was a real challenge and a test of how efficient it is possible to perform a diving operation and the importance of high standard equipment.
