The Maine-headquartered shipyard has built an azimuth stern drive tug to assist ships into harbours and manoeuvre ice in the Great Lakes and St Lawrence Seaway, reports Riviera Maritime Media.
Ice-strengthened tug completed
Seaway Trident was constructed to Glosten’s HT-60 design. By mid-June, it was seen at the shipyard after being painted in the SLSDC colours. Washburn & Doughty launched the tug mid-September and it was completed on the quayside. It will undergo sea trials and sail to the Great Lakes Q4 2022.
With this vessel, SLSDC sought to balance versatility and a compact size with an extra degree of toughness for performing ice management duties during the winter months.
Washburn & Doughty is also building two escort tugs for McAllister Towing. The first of these newbuildings, Jane McAllister, is set to be delivered end-2022 or Q1 2023 and will be followed closely by sister tug Grace McAllister.
Once finished, these mighty tractor tug additions will each have 5,050 kW of power and bollard pull of 85 tonnes coming from two Cat 3516E main engines and Schottel SRP 490 Z-drive units.
