Sea Shepherd - Aberdeen Harbour Scotland - 22/7/2018
Designed by Murray Cormack and derived from their longer NorthBay 17 design, SeaShepherd is a single chine displacement hullform custom adapted to operate stern-to the seas while transferring a pilot off the North Sea port of Aberdeen and also to achieve a continuous service speed of 11.25 knots and a bollard pull of 6 tonnes.
The steel displacement hulled vessel measures 15.25m LOA, beam 5.1m, draught 1.84m and was developed from larger Murray Cormack designed pilot launches for other ports in the north of Scotland.
The vessel will work year round up to three miles offshore and will also be used for general harbour duties including pushing/ pulling larger vessels within the harbour confines and to transport crew personnel to and from ships anchored in the approaches to the harbour. A sweeping sheerline was used to facilitate the boarding of low freeboard vessels midships.
The lines of the vessel were faired electronically by Maritime Lofting Services in Cramlington and the data transferred into kit form by the profiling division of Macduff Shipyards Limited.
Fabrication and fitting out were completed under cover at the firm's base in Macduff, Aberdeenshire.
The hull and superstructure was built under Lloyds Survey with scantlings in accordance with Lloyds Rules - 'Pilot', G2 service area, and a hull certificate provided. Code survey was undertaken by Pirie and Smith Ltd of Aberdeen, representing the Society of Consulting Marine Engineers and Ship Surveyors on behalf of the Maritime and Coastguard Agency, and the vessel was issued with a Pilot Boat Certificate for category 6.
Aberdeen Harbour's design brief included a low noise requirement both within and outside the vessel when underway.
Centa flexible drive shafts and thrust bearings were fitted between the propeller shafts and the resiliently mounted Scania DI12 41M engines. These each produce 355hp at 1,800rpm and are matched to Twin Disc MG5090A seven degree downdrive 2.43:1 ratio reverse reduction gearboxes. Fleetwood sterngear and Lips five bladed propellers are driven through Centa-Drive units with flexible couplings and thrust bearings.
An Onan MDKBD 13.5kW 240V generator is provided in a sound-proof box and a wet exhaust system uses Halyard silencers.
Dutch noise consultants Van Cappellen were employed to specify on-board acoustic noise reducing measures and provide noise level predictions in the wheelhouse and forward accommodation. On trials 65 dB(A) was achieved in the wheelhouse and forward cabin at full power.
The flattened bow profile is strengthened and heavily fendered for pushing and a 6 tonne towing hook with remote release, which was supplied by Britannia Marine Towing Equipment, is mounted aft.
A clutched hydraulic pump is arranged on a drive from the port gearbox powering a Kort KT45DD bow thruster, a Spencer Carter capstan, and MOB recovery derricks and winches manufactured by the yard.
The steel hull has four watertight bulkheads for subdivision and also incorporates four deck lifting lugs set inboard of the pilot / crew handrails for craning the vessel out of the water for servicing at Aberdeen.
Comfortable live-onboard accommodation is provided for two crew in the forward part of the vessel below decks including a two berth/settee cabin, toilet compartment and galley facility.
An Onan genset powers heaters and galley equipment at sea.
The aluminium wheelhouse has seating for up to eight persons.
The helm console forward is arranged with a steering position on centre together with controls to port and navigation aids all within reach of the helmsman.
A second set of engine controls is fitted to starboard to allow the helmsman improved visibility when using the MOB rescue boom over the starboard side.
Hydraulically powered gull-wing MOB rescue booms are fitted across the wheelhouse canopy aft, operable for either wing of the wheelhouse when recovering a person from the water. This system has been used on a number of Murray Cormack pilot boats operating in the north of Scotland where the arrangement was initially developed. Scramble nets are stowed in recesses formed in the wheelhouse sides below the windows. Aluminium luggage bins are provided on the aft deck for use when transporting anchored off ship's crews ashore.
Wheelhouse equipment supplied by Furuno (UK) Ltd includes M1833NT radar/plotter display unit, SC60 satellite compass, Ultrasonic wind sensor, FCV600L/MSD colour sounder, and Navnet station. Simrad Ltd's contribution to a comprehensive fit out includes Raytheon Ray 430 loudhailer c/w two speakers, Sailor RT4822 DSC VHF, Sailor RT 2048 VHF and LS80 internal loudspeaker for it, two Sailor N240 converters, and two Icom IC-M21 handheld VHF c/w chargers.
Sea Shepherd displaces 44 tonnes, has 3,100 litre fuel capacity, 450 litre fresh water capacity, and is crewed by two with a capacity for 10 passengers.
