Norsafe announced the results of the study on its all electric lifeboat, which are powered by ZEM's battery solutions. "The study involved a full design and testing programme as DNVGL-ST-E406 and included CFD simulations, scale model and prototype testing. It has been demonstrated that electrical propulsion is a realistic alternative for free-fall lifeboats.
According to Norsafe, the benefits of the electric lifeboat are:
Significant reduction in OPEX cost
Remote monitoring of equipment from bridge and onshore locations
The driveline can be remotely started and stopped, and performance recorded, without personnel entering the lifeboat
Environmentally friendly with no emissions or fluid spills
Reduced requirement for on-board checks and inspections
90% reduction in air bottle capacity, saving weight and maintenance
No need for diesel fuel reducing problems of supply and contamination
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
Increased safety during sail away because of higher top speed
High level of personnel comfort when at sea due to climate controlled environment as well as reduced noise and vibration
Electric installation has been designed as DNV-GL and NMA requirements
