Testing MARIN tests
deepest TLP Scale model tests have begun on the world’s deepest tension leg platform (TLP) at Maritime Research Institute Netherlands (MARIN) for Chevron USA Inc and Floatec.
the platform in Gulf of Mexico hurricane conditions. The large water depth required the use of the deep pit (30m) in the MARIN Offshore Basin. Together with its dedicated wave generators, wind fans and special current generation system, this basin offers unique possibilities for the modelling of realistic current, waves and wind at scale. The two milestones were celebrated with
representatives of the two clients involved: Ming-Yao Lee, team manager for offshore and marine structures of Chevron, and Edward Huang, director of engineering of FloaTEC. Together they baptised the Big Foot model 9000 in the presence of Arne Hubregtse, the president of MARIN and Bas Buchner the vice president and manager offshore.
Contract Cargotec inks
subsea contract Cargotec has signed a €20 million (US$26 million) contract for MacGregor subsea load and module handling systems to be installed on Hallin Marine Subsea International PLC’s ‘ground-breaking’ design of compact semisubmersible (CSS) offshore vessel. The equipment will be delivered during the second half of 2011. Cargotec’s senior vice president responsible for

The 1581m (5187ft) Big Foot TLP represents
MARIN’s 9000th test model since the Institute started in 1932. Chevron is considering this extended tension
leg platform (ETLP), designed by FloaTEC, for the Big Foot field development in Gulf of Mexico. Te platform will be a local host with dry trees and the associated top tensioned risers (TTRs), with full drilling, workover and sidetrack capability on the topsides. Te field is located in Walker Ridge Block 29 in the Gulf of Mexico. Chevron is the operator of Big Foot and the other co-owners are Statoil USA E&P and Marubeni Oil & Gas (USA) Inc. The model tests are focused on the behaviour of

offshore load handling, Henrik Vildenfeldt, said: “We focus on delivering integrated solutions that will optimise the functions, and thus the overall functionality, of a specific ship type. Contracts such as this are testimony to our customers’ confidence in both the superior technology and reliability of MacGregor equipment, and our ability to provide complete integrated solutions that will ensure sustainable, function-intended operations.” Hallin Marine says the 84m loa by 32m beam
twin-hulled compact semisubmersible (CSS) will be named CSS Derwent, and is the culmination of a five-year project designed to deliver ‘large boat capability’ at the price of a much smaller vessel, with a primary focus on light well intervention. CSS Derwent was designed by STX Canada Marine Inc. MacGregor systems comprise a 150tonnes subsea
active heave-compensated knuckle-jib crane with a 3000m wire capacity, an offshore service crane, several remotely operated underwater vehicle (ROV) launch and recovery systems including moonpool-based and deck-mounted versions with umbilical winches, a module-handling system with a tower, moonpool system and a fully integrated deck-skid system.
