Description

Scarabeo 9 is one of the largest offshore drilling rigs in the world.[3][4] It is the first (and as of 2012 the only) Frigstad Engineering developed Frigstad D90 design rig ever built.[5] The rig is able to operate at the water depth up to 11,811 feet (3,600 m), which is classified by the oil industry as "ultra-deepwater", and its drilling depth is 15,200 metres (49,900 ft).[6][7][8] The water depth still suitable for its operations is twice as much as for Deepwater Horizon.[9] The drilling equipment was provided by the Norwegian engineering company Aker Solutions.[10]

Scarabeo 9 has a length of 115 metres (377 ft) and a breadth of 78 metres (256 ft). Its gross tonnage is 36,863, dead weight tonnage 23,965, and net tonnage 11,059 tonnes.[1] The vessel is powered by eight Wärtsilä 12V32 diesel engines.[1] It is equipped with two cranes.[6]

The rig includes quarters for up to 200 workers. There is also a helicopter deck suitable for MI8, S61, and EH101 helicopters.[6] The rig has been described by the industry sources as "the latest technology for deepwater drilling operations."[9]

Construction and delivery
Taisun crane at the Yantai Raffles Shipyard holds the 17,100 metric ton deck box of Scarabeo 9 in the air as the barge is moved out from underneath.

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.[11]

The rig cost US$750 million to build.[12] 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.[1][13] After several delays at the Yantai Raffles shipyard it was shipped to the Keppel FELS shipyard in Singapore for the final completion in 2010.[7] The reason of delays was related to a number of orders which were carried out simultaneously at the Yantai Raffles shipyard.[5] Changing shipyards caused additional cost of between US$70 and 100 million.[14] Beside of the Keppel FELS shipyard also the SembCorp Marine's Jurong Shipyard in Singapore was considered for the completion works.[10]

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."[13] The incident caused an extensive inspection to assure its seaworthiness.[7] The main part of Keppel's work involved the completion and commissioning of marine and drilling systems on board.[2]

The rig was delivered to Saipem on 25 August 2011.[11] On her maiden voyage to Cuba, Scarabeo 9 was escorted around the Cape of Good Hope by the Fairmount Marine owned tugboat Fairmount Glacier.[15]

Compliance with the embargo against Cuba

The rig was specifically built for drilling in the waters of Cuba. It is compliant with the United States embargo against Cuba, which limits the amount of American technology that can be used in equipment used there, as less than 10% of its parts are American-made.[16][17][18] The news agency Reuters has reported that only the blowout preventer of Scarabeo 9 is manufactured in the United States.[3][16] This is one of the most critical devices for well control during the offshore drilling as malfunctioning of the blowout preventer was one of the reasons of the Deepwater Horizon explosion.[3] However, due to the United States embargo, the original equipment manufacturer is not allowed to provide spare parts or repair items for the blowout preventer.[18][19]

On its way to Cuba, in Trinidad it was inspected by the United States Coast Guard and Interior Department (Bureau of Safety and Environmental Enforcement).[20] According to the statement by the Bureau of Safety and Environmental Enforcement, the vessel is generally compliant with existing international and U.S. standards.[3][21]

Operation

Scarabeo 9 drilled its first well on the Jagüey prospect in the North Cuba Basin for Repsol in the beginning of 2012.[12][22] Provider of immediate well intervention and other well-related subsea services was Helix Energy Solutions Group.[19] After drilling for Repsol, Scarabeo 9 was contracted to drill for Petronas and Gazprom Neft on the Catoche field off the north coast of Pinar del Río Province, and for Petróleos de Venezuela on the Cabo de San Antonio prospect off the west coast of Cuba.[17][23][24] Repsol has also contracted the rig for drilling in Brazil.[17]

gollark: Look, the main code is all right here, other stuff is... well, it's spread across a lot of files, but you can see it, check the `local files = whatever` bit and my pastebin account.

gollark: I'm not saying much about the *other* exploit, because that would provide clues about it.
gollark: There are issues I know of in GPS (pretty obvious, hard to exploit, hard to patch), rednet repeaters (not useful to exploit, easy to patch, not too obvious), rednet itself (obvious, easily exploitable, but most people making serious programs are already aware), potatOS (very non-obvious, not a huge issue as accidental RCE still isn't possible, easy to exploit if you know how).
gollark: We should make CVEs for useless CC bugs!
