Will the LNG engines directly drive the propellers or will they generate electricity to power electric engines that drive the propellers?
The LNG will be powering what is basically a power station. We have four generators and they’ll be producing electricity, which will be producing at around 6,600 volts. That power will then be distributed around the ship in different voltages. And part of that will go to the propulsion of the ship.
Can the ship use biofuel?
The ship will be able to use bio LNG and we’re hoping to source that wherever we can. LNG is not available in every place in the world where we’re going as not every country has the infrastructure. We have to use gas oil in some places, which we are prepared for. Our goal is to utilize bio LNG whenever possible as it becomes more readily available.
Will it be possible to replace the LNG engines with a more environmental solution in the future, perhaps a hydrogen fueled system?
Yes. That is part of the reason why we want a generator as a power station so that in the future, if the technology gets to the point where we can use fuel cells, then we can replace those engines with hydrogen fuel cells. Instead of carrying LNG, we would carry hydrogen.
Does the ship have the ability to use secondary substitute fuel?
The ship’s primary fuel is LNG but we also carry as the secondary fuel, ultra low sulfur marine gas oil. That will be used as a reserve in case of the LNG fuel system not working or LNG not being available.
