Maria S. Merian

One of the world's most modern research vessels — named Maria S. Merian after the sci- entist born in 1647 — was delivered for scien- tific exploration on February 9, 2006. Maria S.

Merian is to support the Polarstern as a floating laboratory during work in Arctic circles.

Polarstern was also equipped with Hatlapa products. Seven special winches were supplied to the shipyard in December 2003 already, which are also used for moving the underwater equipment. Hatlapa has escorted this project for five years, during which time the design of the winches was formed in close cooperation with the order principal BAW (Bundesanstalt für Wasserbau) and the shipyard Krögerwerft in Rendsburg.

ROV Intervention Vessel

Sonsub entered into a long term charter with

Bourbon, for the provision of a new vessel to be dedicated to deepwater intervention in West

Africa. The vessel — to be delivered at the end of 2007 — will be named Bourbon Trieste, in honor of the famous bathyscaphe that holds the world record for the deepest dive. The ves- sel will be 85 m long by 18 m wide with a DP

Class 2 diesel-electric propulsion system. There will be a 100-ton AHC knuckle-boom crane and a 10-ton auxiliary crane.

Based on specific job requirements, Sonsub will install one or two Innovator Heavy Work

Class ROV systems with full 3,000 m water depth operating capacity.

The spread will be dedicated mainly to Light

Subsea Construction and IRM activities in deepwater

Cable Repair Boat

Paras Marine launched its new Cable Repair

Boat, which is the brainchild of Naval

Architect Alastair Hunter. The 7.6-m craft is designed as a fail safe platform for streamer in- water maintenance, to significantly reduce the number of accidents associated with the use of work boats in the Marine Seismic Industry. It is also designed to be used as a fast rescue craft.

The unique hull is designed to allow for cables to be accessed from below in a central well, immediately dispensing with the need for over- loading one side of the craft, or leaning out- board in order to make repairs. Despite being an inherently stable platform, the CRB is designed to survive inversion with automatic engine shut-offs and is fully able to re-start once righted.

Survey Vessel

SeaArk Marine delivered a 42-ft. Dauntless

Class Survey Vessel to the U.S. Army Corps of

Engineers, Navigation Survey Branch of the

Charleston District.

The vessel, The Evans, is tasked with con- ducting hydrographic surveys in Charleston,

Georgetown and Port Royal harbors, as well as other navigable waters throughout the

Charleston, SC District.

The craft will also be involved in

Environmental Management Program projects and regulatory inspections of harbors and waterways. The SeaArk 42-foot Dauntless is constructed of all-welded marine grade alu- minum. The state of the art design incorpo- rates a two-man climate controlled pilothouse and aft survey cabin. Vessel enhancements include a fully integrated

Furuno NavNet system and a comprehensive array of sur- vey equipment. Crew accommodations include hydraulic/suspension seating, marine head, potable water, stove, microwave and refrig- erator. The main propulsion engines are twin Cummins

QSC 8.3M diesels, each rated @ 490 HP with Twin Disc gears. For onboard electrical service, an 8.0 Kw Northern

Lights generator and 50 amp shore power are provided.

Fully operational, the boat achieves a maximum speed of 30 knots.

The Evans will be replacing the current survey vessel
