One recent customer is Mare Safety AS, established in 2000 by Elin Helland and Reidar Vâgeskar, which has delivered a new aluminium daughter class rescue craft named 'MARE MSDC 12' to shipowner Simon Møkster Rederi, which will be fitted to ‘Stril Hercules’ at the Flekkefjord Shipyard.

This follows a collaboration agreement between Mare Safety and shipowner Simon Møkster Rederi to build an innovative class of daughter craft, two of which will be fitted to each of the new 55.2m Area Standby Vessels that he has on order which will operate in the Tampen Oilfield in the North Sea.

Mare Safety in Ulksteinvik is well known as a supplier of rescue craft and man overboard boats. The MARE MSDC 12m rescue vessel is the first of its kind and was designed by  Mare Safety AS to meet the stringent requirements of StatoilHydro’s specification for a rescue craft capable of reaching high speeds and yet have a high bollard pull to enable it to tow lifeboats as well as carry out general operations from the mother vessel.  

The deep 'V' hull features a steep 24 degree deadrise at the transom that increases to a very fine entry forward. A flat chine and spray rails provide an efficient running surface and deflect spray away from the collar to produce a dryer ride. It is easily launched and recovered with a single point suspension and Henriksen off load release hook.

Powered by twin Volvo Penta D6 marine engines rated 435 hp at 3,500 rpm which drive twin UltraJet UJ410 water jets fitted with UltraJet hydromechanical reverse control systems, MSDC 12 achieved a top speed of 36 knots and a 32 knot loaded cruising speed. With a fuel capacity of 800 litres, the craft can operate for up to two days away from its mother vessel.

The test programme, which took place in Ulsteinvik, covered self righting and self bailing, jet and engine performance, shaft torque, power and thrust, during which the UltraJet 410s achieved a bollard pull of 4.0 tons. Sea trials were completed with all systems performing perfectly and exceeding Mare Safety’s expectations. The speed of up to 36 knots were achieved with 8,500 kg deadweight onboard.

The UltraJet 410 was introduced to the UltraJet range early last year and all its benchmarks were met when it was put through sea trials. It was also observed that the improvements made to the steering system resulted in increased speeds during hard turns and lower noise levels.

The inside of the Mare MSDC 12 wheelhouse is fitted with a Kobelt helm pump, Marol servo assist pump, Kobelt control system, Navman 8120 chart, radar and GPS, Raymarine wind instrument, Taiyo VHF finder, Furuno fluxgate compass, Steiner binoculars, Night Jaguar vision binoculars, Furuno Loud Hailer, Navman VHF, Tron Sart radar transponder and 3 piece Møve seats.
