48 Maritime Reporter & Engineering News ? January 2013 NEWSOSVsIsland Offshore Opts for Ulstein SX121 Ulstein entered into a contract with Island Offshore and its partner Edison Chouest Off- shore (ECO) for delivery of a multifunctional offshore vessel based on Ulstein?s SX121 design, with an op- tion for an additional vessel. The ves- sel is prepared and tailored for the well intervention, IMR and SURF segments, and meets the latest requirements for both well intervention and offshore con- struction work. This newbuild is sched- uled for delivery in May 2014. The ship will be based on the SX121 design, a platform on which Ulstein has previously built Þ ve ships. It will be cus- tomized to meet Island Offshore?s func- tional requirements and wishes. The 130 x 25 m ship will be outÞ tted to dynamic positioning (DP3) standards, and will be equipped to perform subsea operations at depths down to 3000m. The vessel can be rigged for well inter- vention and is prepared for the laying of ß exible pipes and cables on the seabed through a VLS tower (vertical lay sys- tem). It also has room for a rotating car- ousel below deck with a capacity to load 2500 tons. An active heave compensated (AHC) offshore crane with a 250-ton capacity at 14m outreach and a below-deck winch will be installed on board. The vessel will carry two deep-sea work ROVs (remotely operated vehicle), one to be launched from the starboard side and one through the vessel?s moon pool. The ship is designed with a large car- go deck for transport of equipment for a multitude of operations, and it will be equipped with diesel electric propulsion and three azimuth main thrusters pow-ered by six large generator sets. The ves- sel has a crew capacity of 130. Island Offshore currently has four ves- sels delivered by ULSTEIN in their ß eet: The well stimulation vessel Island Patri-ot, the subsea construction vessel Island Pioneer, and the two subsea construc- tion and intervention vessels of SX121 design, Island Constructor and Island Intervention.Naval architect Vripack has designed a 43 ft. supply vessel together with Ribbon Yachts in the Netherlands. And by looking at the propor- tions between line and surface, one can easily see that the design of the agile and modern Ribbon 45 SC is the foundation for the sturdy Ribbon Offshore. Vripack?s challenge was to Þ t all their practi- cal knowledge into this design without having to make any concessions. To accomplish this task, close collaboration with Ribbon Yachts tool place. The Ribbon Offshore is designed to be a compact fast supply vessel. The design is suit- able for multiple purposes such as transporting crew and small supplies to and from container- ships in anchor zones, offshore wind farms and offshore multi tasking. Besides that, it can also be used as a pilot-boat, survey vessel, coast guard or salvage and rescue vessel. The strong vacuum injected composite hull is designed to give the Ribbon Offshore a high- tech and stiff structure, suitable for heavy seas. Apart from that this 43 footer is carried out with a solid workboat construction and a sub frame in order to protect her crew. The super- structure is provided with a widened hip and a huge amount of glass, creating a spacious feel-ing and the dominating and powerful look she needs for the job. The Ribbon Offshore is equipped with a ß at 360 degree deck including anti slip and live rail allowing anyone to get on and off board safely at any desired position. The Ribbon Offshore uses the same under- water body as the Ribbon 45 SC, which has very suitable sea going characteristics and makes this bruiser fast, easy manoeuvrable and extremely comfortable at sea.Like the Ribbon 45 SC the Ribbon Offshore has a fully equipped helm and navigation cock-pit which is located in the middle of the yacht, leaving enough space for 10 passengers be-sides the captain and the navigator. In order to maximize comfort, the complete steering and passenger area is placed on shock absorbers in order to minimize the impact of waves.Inside, the Ribbon Offshore is provided with a large storage area in the front. On the lower deck the Ribbon Offshore comes with a private toilet, large lockers and a serviceable seating area. The Ribbon Offshore is water jet powered by two Cummins 600 HP engines, which are con- trolled by the vector stick control system pro-viding easy docking and maneuverability with very tight turning circles and super Þ ne control in narrow quarters.The Ribbon Offshore is Þ tted for the job and is considered an ultimate work boat that ticks like a Swiss watch while being work man proof.Email: [email protected] Designs Heavy Duty Ribbon Offshore MR #1 (42-50).indd 48MR #1 (42-50).indd 481/3/2013 11:36:42 AM1/3/2013 11:36:42 AM
