However, due to the differences in voltage & frequency between shore based and ship based electrical networks this is not always possible. In fact many ship repair yards have to supply dedicated containerised diesel gensets specifically for supply of shore power. These are expensive to run, noisy and require regular servicing & maintenance.
Rotary converters (M-G) sets can be used but are large, expensive and inflexible.
MJR can provide a range of solid state voltage & frequency converters that enable any shore based power supply to be converted to the correct voltage & frequency to enable the ship’s electrical network to be supplied via the shore supply.
The converters can be either permanently shore based, portable (containerised) or installed on the ship and are fully electronic and maintenance free.
We can also provide a range of constant frequency converters that convert the main engine shaft alternator output (variable) to constant frequency & voltage output to enable…
This can bring many benefits to the owner in terms of improved redundancy, lower operating costs, reduction in running hours of auxiliary machinery and increased flexibility.
