Fincantieri Launches 'Scarabeo 5' Semisubmersible Drilling Rig
The semisubmersible drilling rig Scarabeo 5 was recently launched in Italy at the Sestri Ponente (Genoa) shipyard of Fincantieri-Cantieri Navali Italiani SpA. Construction on the rig started in May 1987, and delivery is forecast for 1990. Ordered by the Italian company of Saipem (ENI Group), Scarabeo 5 is a semisubmersible, column stabilized, dynamically positioned drilling unit based on a Maritime Engineering design. The unit has a length of about 364 feet, breadth of 237 feet and height of 143 feet. Scarabeo 5 is fitted with an Integrated Management System. It consists of a totally integrated, thoroughly distributed process control and data acquisition system, based on a proven hardware and LAN, with built-in simulation facilities and field configuration tool. Main functions are automatic power management; fluid management (including stability calculation); rig management such as drilling, logistics and survey; automatic thruster assistance to mooring, including EMP dual redundant hydroacoustic reference system.
Mooring system up to 900 meters will be assured by eight 15-ton anchors, while on depths from 900 to 1,800 meters, Scarabeo 5 will operate in "dynamic positioned mode" by means of eight thrusters based on eight 2,350-kw electric motors. Scarabeo 5 will be able to operate in severe environmental conditions: in operation, it will be able to resist winds up to 33 m/s, current up to 1.0 m/s and significant wave height up to 9.0 meters.
Scarabeo 5 has air-conditioned living quarters for 100 people. All working areas are protected, fully ventilated and air conditioned to allow maximum comfort and safety for the crew.
