Sweden's Dockstavarvet has now
handed over its sixth pilot boat to the
Norwegian Coastal Administration
since deliveries started with 'LOS 115'
'LOS 115' and '117' are single-screw,
16.5-metre, 22-knot boats strengthened
for navigation in ice while 'LOS 116' and
'118' are twin-screw, 17-metre boats based
on an existing hull design which has
already been proved in the Norwegian
Pilotage Organisation. Number '119'
has been reserved for a third unit of the
The three following boats, 'LOS 120',
'LOS 121' and 'LOS 122', have been
redesigned with a modified hull-form
aimed at giving both a softer ride in head
seas and a further reduction of fuel
consumption. At a service speed of 25
knots the consumption is now down to a
mere eight litres per nautical mile; a very
good figure for a heavy-duty vessel with a
full load displacement of 32 tonnes.
The boats are fitted with twin Volvo-
Penta D16 engines with Twin Disc MGX-
5145 Quick Shift gearboxes and fixed
pitch propellers. At Rating 1 (2 x 480kW
at 1,800rpm) the engines are expected to
reach 18,000 hours MTBO and the top
speed is 26.5 knots. Fuel capacity is 3,600
litres, giving a range of 400nm.
Specifications include all state-of-the
art features such as heated decks, boarding
platforms and hand rails, a heavy duty
fender system and the Docksta trade
mark -- a resiliently mounted deckhouse
with a noise level of around 63db(A)
inside at full speed.
The raised wheelhouse is fitted with a
twin-station conning arrangement and
seating for three pilots. The saloon on the
main-deck level has amenities and sofa
seating for up to five additional Pilots.
The boats are fitted with a 10kVA
Perkins/Stamford diesel generator for the
(3 x 220V) AC system supporting domestic
loads and a Servex air-conditioning/
ventilation/defrost system. In addition to
the standard safety equipment the boats
are also fitted with a rescue platform with
davit at the transom.
'LOS 120' is stationed in Kristiansund,
'LOS 121' in Tromsö and 'LOS 122'
will be delivered to Sandnessjöen in
In direct continuation of the last three
boats for Norway Dockstavarvet has
already started production of six similar
boats ordered by the German Government
through Fachstelle Maschinenwesen Nord
in Rendsburg. The boats will be built in
aluminium with classification by
Germanischer Lloyd including Ice-class E.
Modifications of the design include a
slightly bigger deckhouse with a lay-out
with three seats in the wheelhouse (two
crew and one pilot) and a spacious saloon
with six pilot seats, pantry, mess and
The first boat for Germany will be
delivered in December 2010 and all six
boats are to be handed over before
The Swedish Coast Guard is to install
Volvo Penta's Inboard Performance
System (IPS) in an entirely new
type of vessel for sea rescue and
Using the IPS system, the Coast Guard
will reduce the fuel consumption of the
new vessels by about 30 percent.
Since the launch in 2005, Volvo
Penta has sold more than 10,000 units of
the revolutionary IPS system, with
forward-facing propellers. The system
reduces fuel consumption by about 30
percent for planing vessels, compared
with traditional straight shaft and water
jet vessels, while significantly increasing
performance and manoeuvrability.
These factors were key when the
Swedish Coast Guard was making its
decision about the type of drive system to
be selected for the five new 'KBV 312'
vessels that will be used for surveillance,
border control, fishing control, sea rescue
and safety at sea activities.
The order to Volvo Penta consists of a
total of 15 complete IPS systems. Each
vessel will be operated by three Volvo
Penta D13 engines, with IPS drive system
(3 x IPS1050), which will generate
propulsion corresponding to a shaft
installation of 2,349kW per vessel.
The vessels, which will be built at
Baltic Workboats in Estonia, will be 26.5
metres long and 6.2 metres wide and have
a top speed of more than 30 knots. The
'KBV 312' is semi-planing and built of
aluminium and will be equipped with
state-of-the-art technology, with respect to
navigation and propulsion.
The first 'KBV 312' vessel is scheduled
for completion during autumn 2011.
