20 meter Boat for Lotsbetrieb GmbH, Germany
NB 575, LVS WARNEMUNDE, was delivered in Wilhelmshaven, Germany 19.12.2012 exactly 12 months after contract signing and two weeks ahead of schedule. The boat will be operated by Lotsbetreib GmbH of Rostock on behalf of Wasser- und Schifffahrtsdirektion Nordwest at JadeWeserPort, the new deep-water container terminal just outside Wilhelmshaven.
The design is based on a series of 17 meter boats delivered to Kielpilots during 2010 – 2011. The new hull design has a waterline length of 18,5 meter with a very fine entry to full fill a strict specification requirement to give “maximum 0,95 g at the steering position at 25 knots in 2,5 meter waves”. In addition the boat is also self-rightening in all loading conditions.
Main dimensions are 19.4 x 5.45 meter and the boat is built in aluminium with classification by Germanischer Lloyd. Two VOLVO-PENTA D16 main engines of 500 / 550 hp at 1800 rpm each drives fixed pitch propellers through 80 mm stainless steel shafts and Twin Disc MGX-5145 gearboxes giving a very sturdy propulsion package and long MTBO. Speed at 34 tons displacement is 25 knots giving a fuel consumption of around 7,5 l/NM.
The arrangement is laid out with a raised wheelhouse with round-the-horizon visibility for two crew and one pilot seated in Recaro chairs. Aft of the wheelhouse at deck level is the saloon with toilet-room, crew mess and seating for 7 pilots. The entire deckhouse is resiliently mounted to ensure a noise level inside of under 65 db(A) at 90 % MCR.
Heating is provided by a 45 kW Kabola boiler combined with waste heat from the fresh water circuits of the main engines. The system provides ample heating even in winter conditions not only for the interior but also for deck areas, external hand-rails and the boarding platforms.
The electrical system is based on 24 V DC for essential services supplied from 2 x 140 A generators on the main engines. The 400/230 V AC system is supplied by a 12 kW Perkins / Stamford dieselgenerator or shore connection and serves five big heated windows, the aircondition system, domestic services as well as back-up battery charging for the five battery-banks; 2 x Starter, Service, Emergency and GMDSS. The boat is fitted with ample deck lighting including a remote controlled 500 W searchlight and four fixed 200 W bowlights from Norselight.
The navigation and communication package is a system-delivery from FURUNO and comprises two 12 kW radars type FAR-2117B, one with 6 ½’ antenna and 19″ display and one with 4′ antenna and 15′ display, one FMD-3200 ECDIS plotter system with a 19″ display as well as GPS compass, dGPS receiver, autopilot, echosounder, AIS and camera systems.
In addition to the full GMDSS A1 installation there is one extra FURUNO FM-8900 VHF-DSC set. The pilot work-station is fitted with a pilot-plug and an internet connection.
The standard of detailed engineering reflects Docksta´s long standing experience in pilot boat construction with emphasis on safety, fuel economy and long service life with low maintenance costs.
