VIKING
AVANT which was delivered from Aker Langsten AS, Tomrefjord to Eidesvik Shipping
AS, Bømlo in November, was presented with Skipsrevyen's Ship of the Year
award for 2004. The vessel is built with bridge and engine aft, contrary to (probably)
all previously built PSVs. The hull was built at Aker Tulcea in Romania. When
designing this vessel Vik-Sandvik put emphasis on important criteria such as reduced
motions and noise in the superstructure due to location of the bridge, improved
quality of onboard working hours for the crew, better quality on off duty time
onboard and better light conditions in living and working areas, as all of these
are located above main deck. The new design means that the vessel can operate
with her bow facing the weather at all times. The
noise level is reduced as the thrusters are located far from the accommodation
section. The construction with engine and accommodation aft has given the naval
architects more freedom to optimize the foreship to a more fuel effective shape.
Naturally commercial
aspects such as a deadweight and ample tank capacities, as well as good speed
and satisfactory fuel economy, were also an integral part of the design. Less
hull resistance was an important factor in achieving the speed/consumption criteria.
With a dwt of about 5,850 tons and a deck load of about 4,200 tons the VIKING
AVANT can carry significantly more cargo than most of the tonnage available on
the market today. By avoiding the shaft and cable gates the capacity is improved,
and there is a safe-haven with covered discharging manifold under the forecastle.
The design means
that only one manoeuvering position is necessary. The bridge solution is in accordance
with DNV's Naut Bridge. The electronic bridge installations have been done by
Kongsberg Maritime.
VIKING
AVANT's stern slip system is a state-of-the-art rescue contingency system, always
carrying the daughter craft in the stern slip. The vessel can therefore at all
times be ready for action as a rescue ship. Her mode of operation as a rescue
vessel, the stern slip, provides an increased operating window for rescue services
in extreme waters like the Barents. Access to and exit from the daughter craft
is sheltered in the superstructure tunnel providing excellent working conditions.
On delivery from
the yard the vessel entered a five years charter to Statoil for operation in the
Barents Sea. In addition the Charterers have options for further periods of 2x1
years. The area of operation will be for the Snøhvit development where
the vessel will perform supply, standby and emergency towing services.
As
per Statoil's criteria a de-ice classification is essential. This covers the ability
to heat the forecastle, bow area, rescue facilities, railing and gangway. Other
requirements include Clean class, Comfort class, Redundancy of equipment and Oil-recovery
equipment, which is stored in a covered hangar.
The
vessel has a diesel electric propulsion system supplied by ABB which incorporates
four generators each of 1,825 kW, two Compact Azipod propellers each of 3,000
kw, two frequency converters for the main propulsion and two water-cooled transformers
for the main propulsion each producing 4,000 kVA. The vessel's maximum speed is
16 knots.
The
power station consists of four CAT 3516B diesel engines, each with an output of
1,800 ekW, supplied by Pay & Brinck Motor, who also delivered the emergency generator
type CAT C9 of 250 ekW and Aargilon SCR for cleaning of the exhaust gases thereby
reducing the NOx emissions. The Owners have calculated the NOx savings per year
to be about 77 tons.
The
vessel is equipped with two Brunvoll bow thrusters for easier manoeuvering, each
of 1,000 kW, and one retractable azimuth type AR-63 of 880 kW. The Brunvoll Retractable
Azimuth Thrusters installed are used for dynamic positioning. The water mist fire
protection system in the engine room is supplied by Koppernæs.
Hydrakraft
is the supplier of the deck machinery like a towing winch with 75 tons pull, capstans,
tugger winches, windlass mooring winches, a reception system for the workboat
at the stern and a tractions winch drive system for the cargo deck cover. The
cement handling system is from Randaberg Industrier. The MOB-boat is a Norsafe
delivery, and Vestdavit has supplied a single point telescopic davit to the vessel.
The vessel sails
with a complement of 12 persons, but can accommodate 250 persons in an emergency
situation. The electrical installations were taken care of by ABB.
