Newbuilding 441 “Serene” was named, launched and handed over to owners Serene Fishing Co Ltd, Whalsay, Shetland, UK on 25 August 2018 from Karstensen Shipyard.
The hull for “Serene” was built with Nauta Shipyard in Gdansk, Poland and arrived in Skagen end-February 2018.
The partnership of Serene fishing Co dates back to 1955, with the first newbuilding commissioned in 1969. After that another 3 newbuilt Serene’s has followed. Latest Serene was built in 2009, and was sold to Norwegian owners in spring 2017.
Owners in Serene Fishing Co Ltd are Robert J (Bobby) Polson, Tommy Eunson, David Shearer, Bryan Sutherland, George Polson, Gilbert Williamson and Leonard Polson.
Owners and Yard has a long standing relationship, with Owners having maintained and repaired previous vessels for a number of years in Skagen.
The vessel design, specification and arrangements is a result of an extensive and close cooperation between owners and yard. Main focus has been set on optimizing working, safety and comfort for the crew, optimizing catch handling- and storage facilities and optimizing of fuel consumption.
DESCRIPTION:
The hull is built in steel with three continuous decks: 1st-, 2nd and 3rd deck, and with long forecastle- and boat decks. Wheelhouse, boat decks and masts are to be built in aluminium.
Hull shape of round bilge construction with bulbous bow and stern skeg, flared stem and transom stern.
Below decks the hull is subdivided into the following watertight compartments: Forepeak, bow thruster-/sonar room, insulated RSW-tank section with central RSW pump- and manifold room, engine room with main engine connected to one reduction gearbox with one, ducted propeller and aftpeak with fuel- and lub oil tanks.
3rd deck is arranged with: Forepeak, stores, RSW-hold/trunk section with SB/PS corridors and central rooms for unloading (vacuum) system and RSW machinery. Abaft hold section SB engine control room with adjacent switchboard/converter room, PS workshop and stores/room for header tanks, abaft engine store. All aft hydraulic room with steering gear.
2nd deck is arranged with: Forepeak, harbour gen-set room, store room with central room for vacuum compressors, tank loading deck with loading pipes for RSW-tanks and central deckhouse. Abaft midship accommodation area with exhaust trunking/ventilation ducts PS. All aft large net store PS and SB net pounds.
Accommodation on 2nd deck is arranged with 7 single crew- and 3 officers cabins, all with en-suite toilet/shower facilities, laundry, trim room with steam-room and stairs and corridors. In order to create best possible design for low noise, the accommodation is located as far away from the propeller as possible. In addition a number of constructive steps are made, in order to create a low noise level.
1st deck is arranged with: Forecastle with anchor-/mooring winches and integrated roll damping tanks. Abaft forecastle, open deck with sheltered water separator and with forward deck house with sampling room. Abaft midship deckhouse with accommodation. Abaft deckhouse trawl deck with 2 net drums in waterfall arrangement. At transom hydraulic stern gate and hydraulic operated guiding pins. All aft PS fish pump deck, with fish pump and hydraulic hose reel. Integrated in aft ship construction and boat deck 01 is also trawl gallow, which accommodates 2 main towing blocks as well as tail-end and top line blocks. Net sounder winch is fitted on top of gallow.
Accommodation in deck house is: Day room/lounge, cinema, mess room, galley with provision room (and separate fridge-/freezer rooms), changing room, duty mess/coffee bar and stairways and corridors.
On boat deck abaft midship, deck house in centre. Abaft deck house 2 off trawl winches and 1 topline- and 1 tail-end winches.
Accommodation in deckhouse on boat deck contains: 4 officer cabins and hospital, all with en-suite toilet/shower facilities, instrument room and stairways and corridors. On PS of deckhouse MOB deck and –davit.
Wheelhouse on top of deck house, with 360° view. Funnel with deck PS.
All as shown on general arrangement.
Design principles for main engine / auxiliary arrangement are as follows:
On reduction gearbox, 1 Power-Take-Off, mounted with a shaft alternator, producing 3500 kWe.
To supply additional electric power, the vessel is fitted with 2 auxiliary engine / gen-set, 1 emergency/harbour gen-set and 1 harbour gen-set, producing 1254 respectively 250 and 125 kWe.
During heaving/shooting operations at fishing, when the winch system is in use, the gearbox PTO will be clutched in, and electric power will be supplied from the shaft alternator. When there is demand for full power on the winch(es), there will normally not be same demand for power on the main engine. Following the main engine will be power source for both propulsion and winch system.
During normal towing, the shaft alternator will/can be disengaged (from switchboard), and the electrical power will/can be supplied by either of the gen-sets.
The 2 main gen-sets will be able to connect into main switchboard, controlled by the vessels DEIF Power-Management-System. Further on bus-bar breaker is fitted in main switchboard, allowing aft thruster to be fed off shaft alternator and aft thruster and vessels hotel load off the diesel generator sets.
Electrical power system is fitted for sliding frequency (60-50 Hz), by means of frequency converters for 400/440 V and static frequency converter for 230 V. This will allow main engine and propeller rpm to be reduced with 17%. Further on, the vessel will be fitted with a 2-speed gearbox, giving 2 fixed propeller speed steps.
Further on a clutch will be incorporated between main engine and reduction gearbox, as well as a pony motor/starting transformer will be supplied and fitted. This equipment will facilitate declutching of main engine and the possibility of starting up the shaft alternator as an e-motor for propulsion. Propulsion can thus be run as diesel-electric at fixed rpm, used as a take-me-home facility (PTH). Maximum propulsion power for PTH will be 2000 kW.
Above designs and systems ensures an economical running profile of the vessel.
