Recently delivered by the ASL Shipyard, Singapore, the Robert Allan Ltd. designed RAstar 3000-W series ASD tug Svitzer North has been built to a design developed in close co-operation with Svitzer’s operations team, to meet the unique demands of the Port of Geraldton, Western Australia.

With over 400 ship visits per year, the port’s primary cargo is iron ore, with over 10 MTPA exported. The port is located in a sensitive environmental area, requiring the tug to be at the forefront of safety and reliability, and to ensure the safety of all ships entering and leaving the port.

The tug is diesel powered, fitted with twin azimuthing thrusters, and is designed for maximum efficiency and value in the performance of escort and ship handling duties of large tankers, bulk carriers, and containerships.

Particulars of Svitzer North are:

  • Length overall: 30.0 meters
  • Beam, molded: 13.2 meters
  • Depth, molded: 5.63 meters
  • Maximum navigational draft: 5.50 meters
  • Gross tonnage: < 500

Tank capacities are:

  • Fuel oil: 155 cu.m
  • Potable water: 20 cu.m

The tug is designed and constructed to satisfy all applicable Rules and Regulations of Lloyd’s Register of Shipping (LR) and the Australian NSCV for an escort tug with the following notation:

LR ✠ 100 A1, Escort Tug, ✠ LMC, UMS, IWS, Unrestricted Navigation

Robert Allan Ltd. reports that, on trials, the Svitzer North met or exceeded all performance expectations, with the following results:

  • Bollard pull, ahead: 71 tonnes
  • Bollard pull, astern: 68 tonnes
  • Free running speed, ahead: 13.6 knots

The vessel has been designed for an operating crew of up to ten. The Master and Chief Engineer’s cabins along with the galley and mess are located on the main deck. There are four double crew cabins on the lower accommodation deck, as well as a laundry room.

Deck machinery comprises an Ibercisa hydraulic double drum escort winch and two hydraulic vertical anchor windlasses on the bow. The escort winch is spooled with a high-performance soft line on each drum. In addition, a towing hook is provided on aft deck.

Main propulsion for the tug is provided by a pair of Caterpillar 3516C, IMO Tier II 2 certified diesel engines, each rated 2,240 bkW at 1,800 rpm, and driving a Schottel SRP 460FP Z-drive unit.

The electrical plant consists of two identical Caterpillar C4.4 ship service generators, each with a power output of 86 ekW at 50Hz.

Ship-handling fenders at the bow consist of one tier of cylindrical fender at the forecastle deck level and W-block fenders below main deck level. The same type W fender is used at the stern and D-fender along the sheer lines of the main deck.
