Ultra deepwater 6th generation semi submersible drilling rig

The Scarabeo 9 is a last generation semisubmersible unit equipped with a dual RamRig and a Dynamic Positioning (DP3) system. The Mobile Offshore Drilling Unit (MODU) is an ultra-deepwater drilling unit, designed to operate in water depth up to 12,000 ft, and with a drilling depth capacity up to 50,000 ft below the rotary table. The MODU consists of two pontoons and four columns connected to the upper hull (deckbox). The pontoons are connected with four transverse braces attached at the lower part of the columns. The upper hull (deckbox) accommodates the drilling package and general utilities and it is equipped with a permanent accommodation module for 200 people. 

The helicopter deck suitable for the use of a M18, EH101 or 61 helicopter. Fluids in bilges and drains are collected in dedicated tanks. The properties of drain and bilge water is controlled prior to discharge into the sea (max 15 ppm oil). Contents of collection tanks can be pumped to vessels alongside via the loading stations or transferred to portable tanks for transfer to shore.
