[Almost as ironic and telling a story about the end of the fossil carbon
fuel era as the Kentucky coal mine museum switching to photovoltaics to
lower their energy costs compared to local grid electricity powered by
burning coal. In this case, a production oil & gas rig is deploying
electric life boats to reduce maintenance and operating costs.

The world’s first electric free-fall lifeboat has been launched and is
set to go into service.
The boat, built by Dutch boat-builder Verhoef will be deployed at the
AkerBP offshore oil and gas rig in Norway.
Power is delivered by an emissions-free 50kW inboard electric motor,
developed by German marine electric engine company Torqeedo, and
generates an equivalent to 80 horsepower. The Deep Blue inboard electric
motor is powered by three 30.5kWh Deep Blue batteries, sufficient for
the boat to be used in rescue missions as well as ferrying services, and
capable of running for 30 minutes at full speed, and a further
ten-and-a-half hours at half-speed.
A free-fall lifeboat has to withstand the heavy forces experienced when
dropped from a rig, directly into turbulent waters, whilst ensuring the
safety of the crew onboard.
The boat features seating for 32 passengers, but none of the diesel
fumes or engine noise which so capably compliment seasickness. Verhoef
estimates that the electric propulsion system will reduce operating costs.
