Audacious delivery from Macduff
Macduff Shipyards have delivered the new Audacious BF-83, to Whitehills owners David Gatt and Barry Reid.
Audacious represents new developments in the yard’s fishing vessel design, and the new trawler is arranged for both single and pair trawl and is expected work mainly in Scottish waters targeting white fish. Work began on this new model in early 2016 with close collaboration between the owners and the yard to design a suitable layout of trawler to combine a spacious working deck, streamlined catch management system, good hold capacity and also be economical to run.
With the design finalised, the first steel for the hull was cut in the spring of 2017 in Szczecin and the hull was completed five months later to be towed to Scotland for fitting out, a process that took place over the subsequent year as systems from a long list of suppliers were installed. Audacious was then taken to Fraserburgh in October last year for the final coats of paint and for the fishing gear to be taken on board.
Fishing trials took place out of Fraserburgh at the beginning of November with both single trawl and pair trawl arrangements put to the test.
Audacious measures 27.80 metres overall, with a beam of 8.60 metres and a 6.40 metre depth to the trawl deck. Tank capacities are for 48,000 litres of fuel and 32,000 litres of fresh water, plus Audacious has a fishroom with space for 55 tonnes of boxed fish.
As with all Macduff newbuilds, the hull was developed in co-operation with Macduff Ship Design and CFD technology was used to optimise the hull form for fuel efficiency. Macduff Ship Design then created a full set of hull construction plans which were approved by DNV classification and produced the vessel’s stability booklet upon completion. Audacious has a hull with typical modern construction, built in steel and with the wheelhouse finished in aluminium to DNV approval.
The arrangement has a main deck, trawl deck and partial shelter deck. At shelter deck level the prominent feature is the wheelhouse which immediately forward of midships. At this deck level, aft of the wheelhouse most of the deck is open to the trawl deck below, although a passage is provided at the starboard side giving access from the wheelhouse to the aft area where two bagging drums and the gilson winch are fitted along with a heavy gantry supporting three fixed trawl blocks. On the port side a continuous slew EKM624 12t/10m knuckle boom crane is fitted for landing and general duties. Forward of the wheelhouse there is a spacious fore deck where the windlass and also mooring equipment are located.
At trawl deck level, the deck is open from midships to the stern with two large split net drums fitted as far forward as practical, leaving a large working deck area. At the transom the hopper hatch is fitted on the centreline and flanking this is a pair of hydraulically operated stern gates that can be lowered during hauling and shooting. Two hydraulically operated shooting poles are recessed into the deck, and these are used to guiding trawl gear onto the main drums. Immediately forward of the working deck is an accommodation casing which houses a skipper’s cabin with en suite, a two-man cabin, switchboard room and a deck store where various gear spares and trawl sensors are kept. Forward of this accommodation casing is the winch room occupied by three separate split trawl winches.
The extensive hydraulics package on board Audacious was supplied by Bopp and installed by the yard, with JC Hydraulics assisting in the commissioning and setup.
The heavy-duty trawl winch located on the centreline for pair trawling operations has a 24 tonne core pull and is designed to hold a combination of 1000 metres of 24mm wire, 380 metres of 28mm wire and 880 metres of 50mm rope. The two trawl winches intended for single rig trawling have an 18 tonne pull and capacity for 1650 metres or 24mm warp.
Also part of the package are a pair of 16.70m3 split net drums with a 15 tonne pull, two 6.50 tonne bagging winches, a 10 tonne gilson and a hold winch. Bopp also supplied the anchor windlass and mooring winch, the 150kW bow thruster and the 2000 litre hydraulic tank, as well as all of the hydraulic pumps
Below the trawl deck is the main deck split into three different areas. Aft there is a large refrigerated hopper on the centreline which is flanked by an engineer’s workshop to port and a dry locker to starboard. Forward of this is the processing deck where a sophisticated fish handling system including elevator, conveyor bins, main washer, gutting machine washers, chutes, hold bin system, scales and catch management system was designed, supplied and installed by VCU. The fish handling setup includes a pair of KM Fish Machinery KM5 electrically operated gutting machines.
Also within this area is a dedicated ice room where two ice machines, each with a 4.50t/day capacity are fitted. Forward of the processing area is the main accommodation where a large galley/mess is fitted to port and four two-man cabins and a WC is fitted to starboard.
Below the deck working from the transom forward there is an aft peak store followed by the engine room and then a large refrigerated hold which is arranged with a hopper and scales system fitted close to the aft bulkhead and fish box storage forward of this. In the bow are three large fresh water storage tanks for domestic and ice making duty and a bow thruster access compartment. The hopper and hold cooling systems, ice machines and plant were supplied by Norkoel.
Finning Power Systems supplied the 775hp CAT 3508C main engine fitted by a flexible coupling to a Heimdal HGH595F gearbox with reduction of 9.438:1, which in turn drives a 2800mm diameter controllable pitch propeller inside a modern profile nozzle to provide maximum thrust. Main hydraulic power is driven from a PTO fitted to the gearbox.
Also supplied by Finning Power Systems were a pair of CAT C7.1 generator sets, each rated at 150 ekW.
As is becoming fairly standard on Macduff’s newbuilds, a triple rudder system is fitted with the vessel being easily manoeuvrable in port during trials and is expected to keep the required helm to a minimum during trawling. The steering gear system was supplied in full by Scan Steering.
The electronics package fitted in the wheelhouse was supplied by Woodsons Marine Electronics, UK and Furuno, UK.
