Scarabeo 9 is one of the largest offshore drilling rigs in the world. It is the first Frigstad Engineering developed Frigstad D90 design rig ever built. The rig is able to operate at the water depth up to, which is classified by the oil industry as "ultra-deepwater", and its drilling depth is. The water depth still suitable for its operations is twice as much as for Deepwater Horizon. The drilling equipment was provided by the Norwegian engineering company Aker Solutions. Scarabeo 9 has a length of and a breadth of. Its gross tonnage is 36,863, dead weight tonnage 23,965, and net tonnage 11,059 tonnes. The vessel is powered by eight Wärtsilä 12V32 diesel engines. It is equipped with two cranes. The rig includes quarters for up to 200 workers. There is also a helicopter deck suitable for MI8, S61, and EH101 helicopters. The rig has been described by the industry sources as "the latest technology for deepwater drilling operations."
Construction and delivery
Scarabeo 9 was ordered by Frigstad Offshore, a Singapore based offshore drilling rigs management service company. For this purpose, a special project company Frigstad Discoverer was established in 2006. The original name of the vessel was decided to be Frigstad Oslo. In 2007, the project company was acquired by Italian engineering and offshore services provider company Saipem and it was decided to rename the rig Scarabeo 9. The rig cost US$750 million to build. It was constructed at the Yantai Raffles Shipyard in Yantai, China. The contract was signed on 5 April 2006, the keel was laid on 1 April 2008, and originally the construction was to be completed in September 2009. After several delays at the Yantai Raffles shipyard it was shipped to the Keppel FELS shipyard in Singapore for the final completion in 2010. The reason of delays was related to a number of orders which were carried out simultaneously at the Yantai Raffles shipyard. Changing shipyards caused additional cost of between US$70 and 100 million. Beside of the Keppel FELS shipyard also the SembCorp Marine's Jurong Shipyard in Singapore was considered for the completion works. On its way to Singapore, a water leak occurred due to "water raining into the tanks from the top that was not been drained out." The incident caused an extensive inspection to assure its seaworthiness. The main part of Keppel's work involved the completion and commissioning of marine and drilling systems on board. The rig was delivered to Saipem on 25 August 2011. On her maiden voyage to Cuba, Scarabeo 9 was escorted around the Cape of Good Hope by the Fairmount Marine owned tugboatFairmount Glacier.
