Marine electric solutions

Marine electric solutions have been part of vessel design for many years in the form of diesel-electric propulsion or shaft generators, for example. The share of green energy – from renewable sources such as wind, water, and solar – in land-based electrical grids is on the increase. It makes sense for ships to take advantage of shore-based green energy. Depending on the vessel and its operating profile there are many ways to reduce its emission footprint. The key is optimisation: finding the right solution for each vessel.
