Steerprop Propulsors to Improve Oil Pollution Control
in Gulf of Finland
(5
February 2003)
|
|
|
The Finnish Environment Institute together with
the Finnish Maritime Administration recently
ordered a renovation, extension and modification
of the buoy-tender vessel Seili, to be
carried out at the shipyard of Aslemetal in
|
| Olkiluoto,
close to Rauma in Finland. The work includes a
basic renovation - including prime movers and
propulsors - an extension of the hull of almost
8 m (to a new loa of 50.7 m) as
well as modifications to enable efficient oil
response work in both open and ice-covered waters.

Combating oil pollution from the sea surface
(or ice) requires a lot of the vessel and thus
the current propulsion system will be exchanged
to a twin installation of diesel-electric driven
Steerprop SP 25 units according to DnV Ice 1A.
The use of azimuth propulsors provides the vessel
with the position keeping, manoeuvrability and
agility required. Furthermore the propulsors
can be used to improve the oil collecting procedure,
utilizing the propeller stream to prevent the
spreading of the oil film during collection.
Due to the heavy ice class and to improve the
performance in deep ice-rubble, the Steerprop
units will have open propellers, with diameter
of 2.2 m. The propulsion motor power will be
2 x 1100 kW.
|
Seili was originally built in 1979 and has the
following main particulars: |
LOA 42.9 m (new LOA 50.7 m)
Beam 12.6 m
Draft 3.8 m
