The OOS PROMETHEUS was delivered by China’s Yantai CIMC Raffles Shipyard Limited (CIMC Raffles) on Nov. 25.
These semisubmersible drilling rigs were designed and built by the company, which reserves the complete intellectual property. The semisub OOS Prometheus measures 387 feet (118 meters) in length, width 229 feet (70 meters) and depth 124 feet (38 meters).
It has a maximum variable load 5,000 tones and can accommodate 500 people. The ABS-classed semisub can operate at a maximum depth of 3,281 feet (1,000 meters). It is equipped with a set of 1,100 ton deck crane and has clear space of 32,291 square feet (3,000 square meters), which provide plenty of storage room for large sized offshore equipments.
Both vessels were designed and constructed by CIMC Raffles in-house, from basic design, detail design to shop design. CSIC 702 institute and Harbin Engineering University participated into the basic design, for seakeeping test, towing basin test and wind tunnel experiments. Brazil is rich in oil and gas resources in deep sea, which is the main market for deepwater drilling rigs to operate.
At present, over 25 percent drilling rigs of the world are serving in Brazil. CIMC Raffles delivered two deepwater semisubmersibles – SS Pantanal and SS Amazonia – in October 2010 and April 2011, respectively. Now the SS Pantanal is wildcatting the 14th oil well in Campos Basin, and the SS Amazonia, the 4th in Santos Basin, both of them working for Petrobras, and so will the OOS Prometheus.
