World's Biggest Ship Obtains SpeedCast SATCOM Support

[SatNews] SpeedCast International Limited (SpeedCast) has been awarded a satellite service contract by Allseas Group S.A. (Allseas).

The contract covers their flagship vessel, the Pieter Schelte, the world’s biggest ship, which took to the seas for the first time for sea trials in September.  The satellite service provides high-performance broadband connectivity for mission-critical communications between the vessel and the land-based operations.

The Allseas' Peter Schelte.

Allseas is known for their expertise in the execution of large and complex projects for the Oil & Gas (O&G) industry and provides worldwide support to its clients.  Allseas operates a versatile fleet of dynamically positioned pipelay and support vessels including the world’s largest pipelayer Solitaire.  In June 2010, Allseas awarded the contract for building its dynamically positioned platform installation/ decommissioning and pipelay vessel Pieter Schelte to the South Korean shipyard Daewoo. Delivery of the completed topsides lift and pipelay vessel is expected at the end of 2014, ready for offshore operations in the summer of 2015.  At 382 meters (1,253 ft) in length and 124 meters (384 ft) in width, it is the largest ship by area ever built. SpeedCast is already serving the rest of the Allseas fleet: Solitaire, Audacia, Lorelay Calamity Jane and Tog Mor.
The Pieter Schelte was designed to lift oil rigs out of the water and move them to shore for disposal.  The massive vessel can lift topsides, the upper section of an oil rig, weighing up to 48,000 tons, and can also lift jackets, the bottom section of rigs, weighing 25,000 tons.  It can then transport the top and bottom sections of the oil rig to shore.  The vessel is able to raise and lower itself in the water by 25 meters (82 ft) in order to manage the huge weight demands of moving an oil rig.  Pieter Schelte also boasts a pipelay tension capacity of 2,000 tons, making it the largest pipelay vessel in the world.  Top speed is 14 knots (25.9 km/h) and it can 571 crewmembers.  
SpeedCast designed a customized communications solution to meet the unique requirements of Allseas for the Pieter Schelte, which include operational and ship management applications, as well as crew communications.  SpeedCast’s advanced solution uses dual maritime VSAT systems, with frequency diversity, including C- and Ku-band, as well as an L-band backup, to provide Allseas with a highly reliable, highly resilient communication solution with world-wide coverage.  The solution provides full system and equipment redundancy for both data and voice services to deliver guaranteed reliability under all operational conditions.
