RASCAL and ROWDY tugboats delivered to Brusco Tug & Barge

April 2, 2025

Robert Allan Ltd. is pleased to announce the delivery of two very compact high bollard pull ship handling tugs. RASCAL and ROWDY were successfully delivered to Brusco Tug & Barge in September 2024. These newly completed RAscal 2000-D series tugs were constructed at Diversified Marine Inc. of Portland, Oregon and at over 40 short tons are the highest bollard pull tugs of this size designed to date by Robert Allan Ltd.

These compact tugs are well suited for harbours where smaller though still powerful ship assist tugs are needed, as well as being available for general harbour and coastal towing. The compact wheelhouse allows the tug to get under the flare of even smaller vessels with a folding mast allowing reduced air draft. Two double crew cabins are provided in the lower accommodation, along with a spacious mess and galley.

The top tier of bow fendering is a Schuyler laminated fender, which is ideal for resisting wear. Lower tiers at the bow, down to the waterline, are softer Schuyler SRD-D3 loop fender with additional loop fendering at the stern and aircraft tires fitted along the sheer.

Particulars of the tugs are:

  • Length overall: 65′
  • Beam, moulded: 32′
  • Depth, moulded: 11′-6″
  • Gross tonnage:
    • ITC: 159
    • US Regulatory: 98

The tugs were designed and constructed to comply with all applicable Rules and Regulations of USCG, 46CFR, Subchapter M and ABS Class.

The tugs feature two Caterpillar C32 main engines, rated at 1450 bhp at 2050 to 2150 rpm and meet EPA Tier 4 emissions requirements with use of an SCR diesel exhaust aftertreatment system. These engines power two Berg MTA 522 Z-drives fitted with 87″ fixed pitch propellers. The electrical plant consists of two identical diesel gensets, each with a power output of 99 ekW 480V, 3-Phase, 60 Hz.

Tank capacities are as follows:

  • Fuel oil: 6900 gallons
  • Potable water: 1100 gallons
  • Diesel exhaust fluid: 500 gallons

Sea trial results showed the RAscal 2000-Ds met all requirements of the design.

  • Bollard pull, ahead: 85,000 lbs
