Anglian Princess - Maritime and Coastguard Agency
Source: www.maritimejournal.com/archive101/2002/november/vessel_l...
Anglian Princess is the first of a pair of sister-ships intended to fulfil a vital role in a prestigious contract with the Maritime and Coastguard Agency as Emergency Towing Vessels (ETVs) under a contract awarded in February 2001. Klyne Tugs provide four powerful tugs to assist in protecting the British coastline against marine accidents and any resulting pollution
Anglian Princess was constructed to a Rolls Royce Ulstein UT 719-T design for an anchor handling tug/supply vessel in 2001 (?). The 67m ship is intended primarily for towage and salvage in its present role but is fully equipped to carry out the normal duties of an offshore anchor-handler. Operating under the British flag, the vessel is classed Lloyds Class +100 +LMC, UMS.
The hull follows the well-established UT 700 series configuration and has a length overall of 67.4m, a breadth of 15.5m, a maximum draft of 6.2m and a gross tonnage of 2258 tons.
In common with all UT 700 vessels, sea-keeping qualities are enhanced with a high forecastle and ample freeboard. The clear working deck aft has an area of 344sq/m and a maximum cargo capacity of 700 tonnes.
Substantial guard-rails are fitted, as per normal offshore practice, and the open stern incorporates a 2.5m diameter roller with a safe working load of 500 tonnes.
Two Wartsila 16V 32LND diesels rated at 16,500bhp/ 12,000kW (total) running at 750rev/min MCR supply power for the vessel's main propulsion system. The main engines run at constant speed and transmit power through Rolls Royce Ulstein gearboxes to controllable pitch propellers, rotating within fixed nozzles. Twin 'high lift' flap rudders are operated by Tenfjord SR 662 steering gear and can be controlled independently or in unison.
This propulsion system gives the vessel a bollard pull of over 180 tonnes and a maximum free running speed of 17 knots.
Representative fuel consumption figures are quoted as 45 tonnes per day at 17 knots and 24 tonnes per day at 12 knots. For a vessel of its size Anglian Princess is extremely manoeuvrable, a feature aided by two electrically powered bow thrusters of 588kW and a similar stern thruster of 660kW.
Electrical power aboard a vessel of this type is an extremely important factor. Two AVK shaft generators, coupled to the propulsion gearboxes each have an output of 2,800kVA, at 440V, 60Hz. Two Cummins powered auxiliary generators are also installed. One for general use rated at 300kW and a smaller unit of 70kW for emergency and standby use. Electrical power is controlled and distributed through large switchboards located in the engine control room. The control room, situated forward of the engine room houses controls, monitoring and alarm systems for main propulsion, power generation, tank capacities and auxiliary machinery.
The towing winch installed in Anglian Princess is a massive Brattvag, triple drum, hydraulically powered, machine with a line pull on each drum of 300 tonnes and brake holding capacity of 450 tonnes. Each drum is capable of holding 1500m of 76mm diameter steel wire rope. Non-declutchable cable lifters are fitted, on the port and starboard ends, to handle 3.25in chain. Also provided are hydraulically powered reels for spare towlines, anchor-handling wires and pennants. Line handling equipment includes a set of Karm forks and towing pins with a safe working load of 500 tonnes, located forward of the stern roller.
Other deck equipment includes two 10 tonne hydraulic tugger winches, two 10 tonne capstans, and an ROV approved deck crane. Supplied by 'Crane Power', the latter has a capacity of 3 tonnes at 15m radius.
Stowed beneath it's own single arm davit is a Viking fast rescue boat. On the foredeck, a Brattvag windlass is equipped with two cable lifters to handle a pair of Spek anchors each with 460m of 38mm chain. The windlass is also fitted with two mooring drums and two warping heads.
Anglian Princess is equipped for fire fighting with two Skum 'Fire Chief' combined water /foam monitors located at the after end of the bridge deck.
Water is supplied to the monitors by two Skum SFP250X350 pumps each with a capacity of 1200cu/m/hr. The pumps are driven from the front of each main engine via Norgear 'step-up' gearboxes.
The spacious, well glazed, wheelhouse is divided into three distinct areas - the main console and forward control position, the after control position with windows overlooking the afterdeck and winches, and the radio and communications desk.
Located on the main console are the main propulsion controls and all of the equipment needed to navigate the vessel at sea.
An Anschultz Nautopilot NP 2010 autopilot is fitted, takes inputs from a Standard 20 plus gyro-compass from the same manufacturer. An extensive Furuno 'bridge electronics package' includes Furuno S-band FAR 2835 S and X-band FAR 2825 radars, two Furuno GPS 80 global positioning systems, an FE 700 echo-sounder (with a repeater at the aft station), a DS80 speedlog, and Furuno GD 380 ECDIS display and video plotter.
When manoeuvring the vessel can be controlled using the Rolls Royce 'Poscon' P450, single joystick control system that fully integrates the functions of main propulsion, rudders and bow and stern thrusters. The system enables the vessel to be moved in any direction while a predetermined heading is maintained. A neat 'joystick' controller is provided in three locations, the bridge wings and aft control position. The aft control position, as with all modern vessels of this type, has an exceptional view aft and is the natural location from which to control the vessel whilst manoeuvring to pick up a tow, anchor-handling and many similar operations. All of the major propulsion and winch controls, and many essential navigational and communications systems are duplicated on three consoles adjacent to a pair of fully adjustable chairs.
The radio desk and main console carry an extensive outfit of communication equipment.
A Furuno SSB Transceiver FS-1562-25 and Furuno DSC-60 radios are installed along with FM 850 and FM 8700. A Furuno Felcom 82a satellite communications system is installed with facilities for phone, fax, data and telex. A Telular Corporation SX4e GSM system also provides facilities for phone, fax and data. Navtex is handled by a Furuno NX 50 set and Weather fax by a Furuno FAX 214. An onboard telephone network covers the entire vessel and is controlled by a fully automatic Vingtor ASA-101 exchange. McMurdo R2 handheld VHF radios are provided for GMDSS use and UHM sets are carried for general local communication.
The accommodation aboard Anglian Princess is extensive, fitted out to a good standard, and can be fully air-conditioned.
Fourteen single and three double cabins all have en-suite facilities.
A well equipped ships office, a reception and conference room, and crew lounge are also provided, along with a hospital and a normal galley and laundry.
Storage facilities throughout the vessel are more than adequate for both, domestic, engineering and marine equipment and a small but well equipped workshop is situated aft of the main engine room.
