Vacons control electric propulsion on M/S EVA 316
M/S EVA 316 CONVERTED INTO A VESSEL CAPABLE OF
OIL COLLECTION IN ICY CONDITIONS
M/S EVA 316 will be the world’s second vessel capable of oil collecting in icy conditions. Just like its sister
vessel M/S Seili, M/S EVA 136 has undergone a major re-modelling process, now equipped for ice breaking and
oil combatting. During the re-modelling process the vessel was also fitted with Vacon liquid-cooled
main propulsion drives.
D
ynamic positioning in icy conditions
requires a lot of power. Therefore,
diesel-electric propulsion as an energyefficient solution was an excellent choice
for EVA 316. In diesel-electric propulsion,
energy savings are achieved e.g. by AC
drives which control the speed of the
motors. Additionally, AC drives improve
reliability and enable optimum design of
propellers to secure an ideal output ef-
fect. Vacon’s configuration of the drives
also allows certain degree of redundancy.
Scandinavian Electric Systems* in Norway
was responsible for system integration and
delivery of cabinets.
Sea trial tests on M/S EVA 316 were
carried out in mid-February 2006 in the
Gulf of Finland, and the test results were
encouraging. With the Pärnu Bay as its
operation area, M/S EVA 316 will consider-
ably enhance oil spill response readiness in
the eastern Gulf of Finland.
REGENERATIVE LIQUID-COOLED
DRIVES SAVE SPACE AND ENERGY
The owner, Estonian Maritime Admistration, chose Vacon’s regenerative liquidcooled drives as they require only a small
space for assembly and no additional
filters are needed onboard to meet ap-
