Low fuel consumption on SOVs

Low fuel consumption on SOVs

Although both the ‘Esvagt Froude’ and the ‘Esvagt Faraday’ have been painted in the familiar orange-red ESVAGT colour, their design is entirely green. The goal is low fuel consumption.

The vessels are equipped with Siemens Blue Drive Plus system; an innovative and fuel-saving DC direct current system. With Siemens Blue Drive Plus system, the rotation speed of the vessel’s diesel return current/power varies according to load instead of running at a constant revolution speed, which reduces fuel consumption.

“Our expectations of low fuel consumption have so far been met to the full,” says Kristian Ole Jakobsen, Chief Operating Officer at ESVAGT.

Our environmental approach has been extended beyond the direct current system. The hull has been energy optimised to such a degree that we have installed LED lights, propulsion units with counter-rotating propellers, control of all thrusters and larger consumers with current converters, recycling of waste heat from the diesel engines for heating in the accommodation areas – and more.

The feedback we have received from the vessels tells us that these systems are working optimally.

Another expected benefit in choosing the direct current system was the reduction in noise and vibration in the vessel – expectations that have been fulfilled.

“The vessel is very comfortable and the noise and vibration levels from the vessel’s diesel engine system are significantly lower,” says Kristian Ole Jakobsen.
