Dutch marine contractors Seacontractors presented the "Speed & Stability", a new multicat-type workboat with a movable centre hull at the Europort exhibition.
The new design measures 43m LOA, with a beam of 13m and a draft of 1m to 1.6m depending on the use of the centre hull. It is claimed to be up to 90% more economical or up to three times faster than similar vessels. The movable centre hull system has been patented worldwide.
"The extraordinary thing about this vessel is the combination of speed, stability, adaptable and effective buoyancy and high tractive power, said spokesman Jacco Wakker. "According to the desired use, any of these properties can be enhanced. During sailing the centre hull will be lifted, then once at the working site the buoyancy can be increased by inflating the special cushions, which are located between the two hulls, making it a fully stable workboat."
Provided with powerful cranes, the vessel is fully self supporting as a cable layer. It is equipped with DP, which in combination with two bow thrusters enables it to maintain precise positioning on work sites. As a transport vessel, the Speed & Stability features four 900 kW Hamilton water jets of Type 811 and can achieve a top speed of 33 knots. It can be used for transporting equipment, fuel, drinking water and personnel.
The Dutch company K & W Trans is responsible for the design and construction of the Speed & Stability. Its regular customers are local, regional and national authorities and national and international dredging and offshore companies.
