VIKING Norsafe has developed the E-GES free-fall lifeboat in close co-operation with DNV GL and NMA (Norwegian Maritime Authority). The objective was to assess the feasibility of an electrically powered free-fall lifeboat concept and to determine reductions in operation and maintenance efforts. The basis of the study was the VIKING Norsafe’s E-GES 45 free-fall lifeboat, already built in compliance with DNVGLST-E406. All diesel related propulsion equipment was removed and replaced with an electrically driven system. The study involved a full design and testing programme as DNVGL-ST-E406 and included CFD simulations, scale model and prototype testing. After a two year program it has been demonstrated that electrical propulsion is a realistic alternative for free-fall lifeboats. VIKING Norsafe E-GES lifeboats are already available for offshore customers. n Significant reduction in OPEX cost, hundreds of hours reduced in maintenance intervention n Remote monitoring of equipment from bridge and onshore locations n The driveline can be remotely started and stopped, and performance recorded, without personnel entering the lifeboat n 90% reduction in air bottle capacity, saving weight and lowering maintenance effort n Environmentally friendly with no emissions or fluid spills n No need for diesel fuel reducing problems of supply and contamination n Redundancy is given by a battery management system (BMS) meaning that, in case of failure or damage, the lifeboat is still functional even with one battery - so there is full redundancy n Increased safety during sail away because of higher top speed n High level of personnel comfort when at sea due to climate controlled environment as well as reduced noise and vibration FOR FURTHER INFORMATION WWW.VIKING-LIFE.COM Fully electric drive-line VIKING LIFE-SAVING EQUIPMENT Protecting people and business
