NO. 3. 2010. SAFETY & SUPPORT AT SEA
FRB 15C adapted to the sea windmills Sea windmills are an increasing energy resource so ESVAGT has developed the FRB’s so that they are now available in a special version suitable for windmills. The development has been carried out together with Vestas.

This can happen in this part of the world as well where the FRB 15C in versions 65 and 66 have got a new profile. - Boat landings at the platforms of the sea windmills must be done safely, says Ole Andersen, one of the founders of ESVAGT: - We have cooperated with Vestas on the construction of a new bow which enables the boat to slide up and down while people are embarking and disembarking on the platform. The bow is made of soft foam stuffed into a strong cover made of rubber. According to Service Manager Bjarne Mikkelsen it is to
be considered as a crown that is put on a tooth. - It is fitted on the outside of the existing bow, but it was exciting for us to see if we had made it strong enough and satisfactory fitted to the boat with the heavy loads it is exposed to from the sea. Fortunately we succeeded and it has already been tested and SOLAS approved, he says. New engines The new bow is not the only thing that has been changed in the FRBs. The 5-cylinder Volvo diesel engines now have increased HP covering a span from 140 to 220 HP, where they used to cover a span from 130 to 190 HP.
This gives a better acceleration. At the same time the navigating handle is now electronically controlled and built into a water proof steel box: - In this way we avoid corrosion of the cables as the material no longer is exposed to salt water. Servicing will be easier, and we must say that Volvo has done all we have asked from them in their continued development of the engines, says Bjarne Mikkelsen. Other changes include new led-search lamps and an aluminium bottom frame meant for 300 kg heavy tool boxes – something that was asked for and developed in cooperation with Vestas. n
