PSV icebreaker designed to be green
Building on recent ice classed OSV designs, Aker Arctic has produced a
new PSV for ice management.
I
n 2005, Aker Yards took the decision
to produce its own designs for
offshore support vessels (OSV),
including platform supply vessels (PSV),
dive support vessels, and remotely
operated vehicles, which have been
contracted to companies such as Olympic
Shipping and Geo Subsea.
In 2006 the company began to develop
Arctic OSVs, and based on recent ice
classed builds, such as Fesco Sakhalin
- which has a double acting concept
selected by Exxon, and Polar Pevek -
which assists tankers in the De-Kastri oil
loading terminal offshore Russia, Aker
has now introduced the ARC 105 PSV
concept.
The 105 PSV has an overall length of
99.2m, a beam of 21m, and a deadweight
of 4200dwt. It has 18,000kW of power,
and two azimuthing propulsors provide Aker’s ARC 105 PSV is flexible and environmentally friendly.
