Propulsion Drive Systems - Speed Drive Systems
Bakker Sliedrecht Electro Industrie B.V. at home in all facets of electrical engineering
Electric drive systems and energy supply for propulsion and sidethrusters invariably means that there are special high requirements for: noise and vibration levels, safety, redundancy, fuel consumption, environment, flexible installation possibilities, maintenance, etc.
There has been a sharp increase in the application of electric drive systems for main and aux. propulsion, bow and stern propellers in recent years, even more so with the advance of low maintenance systems in the form of AC motors with frequency control.
Bakker Sliedrecht has carried out several projects over the last 25 years, for main, auxiliary and emergency propulsion and side thrusters. In several cases a combination of these is used, including power and ship management systems, control by Dynamic Position (DP) systems, etc.
Various possible applications
The choice of an electric drive and energy system mainly depends on the purpose of the application and its requirements. Applications include: research vessels, ferries, naval survey vessels, lighthouse (buoy) tenders, dredgers, offshore vessels, trawler, long-liners, crane vessels.

Propulsion drive systems generally consist of several AC or DC motors with static converters for continuous speed control, possibly combined with a number of side thrusters and in some cases connected to a DP system. An important factor is whether the propeller is fixed or controllable (FT or CT). It goes without saying that fixed propellers give: higher efficiency, smaller diameter, low noise and lower maintenance.
Power generation comprises a number of diesel generator sets, often in combination with a power/ship management system. Our reliable systems require little maintenance. In case of low noise requirement generator sets are mounted vibration free, as groups or individually positioned, in a sound proof environment. The most commonly used system is the low maintenance AC system, however when there is a special requirement for very low noise and vibration levels, a DC direct drive system is favourable. Bakker Sliedrecht can offer or advise you in well thought-out AC and DC systems.
