5th generation semi submersible drilling rig

Born of the Friede & Goldman enhanced Pacesetter GVA design flotel Safe Supporter in 1999, advanced fourth generation semisubmersible drilling rig Scarabeo 7 is outfitted for operations in water depths down to 1,500 m. With main deck dimensions of 77.5 m x 61.3 m, variable deck load in drilling mode equal to 4,500 tons (m) and moon pool dimensions of 6.3 m x 24.6 m, Scarabeo 7 is a highly versatile drilling unit. In keeping with the highest environmental regulations, the Scarabeo 7 is ‘zero pollution’ and ‘zero discharge’. 

Propulsion and stationkeeping on this 19,000 tons (m) unit is controlled by four 2,400 kW Kamewa computer assisted azimuth thrusters with 40 tons (m) of thrust each and a combination chain/wireline mooring system, deployed via BLM winches with 250 tons (m) rated bollard pull and dressed with eight 15,000 kg Vryhof Stevpris anchors. Power to the unit is supplied by five Nebb 2,880 kva and two ABB HSK900 each driven by five Nohab F212v, 2,560 hp and two Caterpillar 3612v, 4,820 hp.

DRILLING EQUIPMENT

The Scarabeo 7’s drilling equipment is designed to reach a vertical depth of 25,000 ft and is outfitted with a 2 million lbs static load derrick (1.5 million lbs dynamic hook load) and a 650 tons (m) Hydralift top drive. Vessel motion is compensated by a Hydralift 600-25 crown mounted heave compensator rated for 750 tons (m). At the heart of the Scarabeo 7’s drilling equipment is a Wirth GH 3000 EG drawworks driven by 3,000 hp electric motors and fitted with a state-of theart regenerative disc braking system, combined with a Baylor braking system. In converting the Scarabeo 7’s working environment, great importance has been placed on using the latest generation equipment. Among the features designed to improve both the quality of the service and safety standards onboard are: a highly automated electronic controlled drilling cabin, computerised data acquisition system, automatic elevators integrated with the pipe handling system and automatic roughnecks. The unit has a 18.75 in 15 k blow out preventers controlled by the latest multiplex system for improved safety and reliability.

 

SYSTEM

Experience has led to the development of a system for the converted Scarabeo 7 that has a high degree of redundancy. The unit’s system can draw on power supplies from redundant subsystems or may be controlled from alternative control stations, greatly reducing the possibility of total blackout and improving operability in an emergency.

 

ACCOMMODATION

The accommodation module has been made in accordance with the fire protection rules provided for units involved in oil production. It is designed to accommodate 150 people with a high level of comfort: 2 Tv rooms, cinema, coffee shop, gymnasium and sauna.
