Motor Yacht Matsko: Quiet, inexpensive energy

SNIPPET:

Design brief: Quiet energy onboard with fuel savings

The aim of Matsko’s investment company (Fuego Ltd.) was to have an AC power supply on-board, without using a generator or shore supply. The project was assisted by the fact that Fuego had all the necessary skills to wire the installation. Based on this information SCHRACK TECHNIK were able to develop a solution and supply the system components. All of the new essential components were manufactured and supplied by Victron Energy.

Originally the vessel’s electricity was supplied by the on-board generators or shore supply. This resulted in the generators having to be used in quiet places in nature when anchored, as obviously no shore supply was available. This was particularly unwelcome at night when trying to enjoy a peaceful evening in some quiet hidden bay. Whilst no air conditioning was required throughout the evening and night, the generator was required to cover refrigerators and some lighting. Although electricity consumption was relatively small, there was always the irritation of the generator ‘muttering’ all night. Furthermore it is known that when a generator is operating in this way it is substantially under loaded, i.e. well below rated load, so unfortunately it is not running in a fuel efficient way.

Generator fuel consumption was around 4 l/h at idle, i.e. with a light load, and 6 l/h at full load. The idea was therefore to completely shut down the generator in the evening and the morning and use ‘quiet energy’ to power the refrigerator and lighting. Then if the vessel were to sail during the day, the main engines would run, with both generators working which you can then load for any additional battery charging.

This can achieve two objectives: when the generators are operating, they are working in the area of higher loads, so the better efficiency in terms of the number of litres of fuel with energy being produced more efficiently. Now any persons on-board can enjoy a peaceful sleep with ‘quiet energy’ being supplied for the night maintenance of the vessel, when at anchor. But it is also clear that by paying attention to the energy consumption at sea and when berthing in a marina connected to the shore supply, that instead of using the generators such an approach can reduce overall power consumption even further by using the silent low-cost shore energy to charge batteries, in order to be ready for sailing the following day.

All of these goals can be achieved by adding a suitable battery bank to store energy which can then be used later. This desire for tranquility on-board also decreases the overall operating costs of the system too.
