Three more Pilot Boats from Docksta to Norway
DOCKSTAVARVET has now handed over the sixth Pilot Boat to the Norwegian Coastal Administration since deliveries started with LOS 115 in 2007. LOS 115 and 117 are single screw, 16.5 meter, 22 knot boats strengthened for navigation in ice while LOS 116 and 118 are twin screw, 17 meter, boats based on an existing hull design which was already proven in the Norwegian Pilotage Organisation. Number 119 has been reserved for a third unit of the ice-going type.
The three following boats, LOS 120 – LOS 122, have been redesigned with a modified hullform 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 8 l/NM; a very good figure for a heavy-duty vessel with a full load displacement of 32 tons. The boats are fitted with 2 x VOLVO-PENTA D16 engines with Twin Disc MGX-5145 Quick Shift gearboxes and FP propellers. At Rating 1 (2 x 480 kW at 1800 rpm) the engines are expected to reach 18.000 hours MTBO and the top speed is 26.5 knots. Fuel capacity is 3600 litres giving a range of 400 NM.
The specification includes all the state-of-the art features including 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 63 db(A) inside at full speed. The raised wheelhouse is fitted with a twin-station conning arrangement and seating for three Pilots. The saloon on main-deck level has a toilet room, pantry and sofa arrangement seating for up to 5 additional Pilots. The boats are fitted with a 10 kVA Perkins/Stamford diesel generator for the 3 x 220 V AC system supporting domestic loads and a SERVEX air-condition/ventilation/ defrost system. Each main engine drives a 140 A alternator for the 24 V DC systems which have separate banks for start-, service-, emergency- and radio batteries.
The navigation / communication equipment is delivered by PRONAV / JRC and includes JMA-5310 and JMA-5210 black-box radars, JHS-182 AIS, NCR-333 Navtex, FF-50 echosounder, CSI Vector PRO GPS compass, Northstar MX500 DGPS, SIMRAD AP-50 autopilot, Maris AEC-6910 chart system and three 19 inch interconnectable flat-screens from Hatteland. For the Pilots an additional 15 inch screen plus a Pilot-Plug is provided to give access to situation awareness before boarding. Two SAILOR RT- 5022 stations are included in the GMDSS A1 package.
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 July 2010.
In direct continuation of the last three boats for Norway DOCKSTAVARVET has already started production of 6 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 Iceclass E. Modifications of the design includes a slightly bigger deckhouse with a lay-out with 3 seats in the wheelhouse (2 crew and 1 pilot) and a spacious saloon with 6 pilot seats, pantry, mess and toilet-room.
The first boat for Germany will be delivered in December 2010 and all six boats are to be handed over before 31.12. 2011. The boats will be operated by Lotsbetreibsverein, Aussenstelle Kiel on behalf of Lotsenbrüderschaft Nord-Ostseekanal II / Kiel / Lübeck / Flensburg replacing 6 boats built in Norway around 1980. The technical requirements were quite demanding and the order was won in stiff competition with a number of other European shipyards.
