At 28 metres in length, with approximately 70 tonnes bollard pull and 5240 kWh of battery capacity each, the first-of-class ElectRA 2800 battery-electric harbour tugs will perform the majority of their ship-berthing and unberthing missions on battery power. Bollard pull is primarily used for measuring the strength of tugboats, with most commercial harbour tugs having around 60 to 65 tonnes-force.

With ample clean hydroelectric power available in Kitimat, the harbour tugs will be able to recharge from dedicated shore charging facilities at their berths between jobs, effectively reducing emissions to near-zero. Because of their battery propulsion, they are also expected to be exceptionally quiet, both onboard and underwater.

The larger RAstar 4000 DF vessels will be the most powerful Azimuth Stern Drive (ASD) escort tugs on Canada’s west coast, and will rank among the world’s highest-performing escort tugs.

At 40 metres in length (roughly half the length of a football field) and with over 95 tonnes of bollard pull, they will generate indirect forces of approximately 200 tonnes. ASD tugs are equipped with two stern engines capable of generating a 360°, all-directional propulsion force.

The RAstar 4000 DF escort tugs will perform the majority of their missions using natural gas as their primary fuel. This allows major emissions reductions compared to conventional diesel tugs of the same power, in compliance with the most stringent emissions standards in the international marine industry. In addition to these environmental benchmarks, the escort tugs will be capable of pollution response/oil spill recovery, fire fighting of marine terminal fires, person overboard response, and emergency towage of vessels.

As a fleet, the new escort and harbour tugs are expected to reduce carbon dioxide emissions by up to 10,000 tonnes per annum compared to diesel-powered alternatives, with major reductions of nitrogen oxides, sulphur oxides, carbon monoxide, and particulate matter as well. In addition, all of the new tugs will be equipped with the external fire-fighting capability of 2,400 m³/hr (pumping enough water to fill one Olympic-sized swimming pool every hour).

“As majority owner of HaiSea Marine, we’re excited about the opportunities Haisla members will have working locally in the marine industry,” says Crystal Smith, Chief Councillor of the Haisla Nation. “It’s extremely important to us that aside from being one of the most powerful tug fleets on the west coast, it will also be one of the greenest ever assembled, anywhere.”

HaiSea’s Senior Project Manager, Captain Jordan Pechie, says the new partnership is a perfect fit. “Seaspan and the Haisla have hundreds of years of combined experience in these waterways,” he notes. “Our mandate is to operate at the highest level of safety and environmental standards, which will allow this legacy to thrive for generations to come.”

RAL President and CEO Mike Fitzpatrick also welcomes the opportunity to work with the Haisla Nation, noting that his firm already has a long-standing relationship with Seaspan. “We value highly the many quality shipyards with whom we have forged close working relationships over many years, and who have helped immeasurably to demonstrate the quality of our brand,” he says.

The new tugs will arrive well in time for LNG Canada’s first cargo at mid-decade.

“The ElectRA 2800 and RAstar 4000 DF tugboats will be a welcome sight in Kitimat Harbour and Douglas Channel,” says Captain Mark Turner, LNG Canada’s Marine Superintendent. “They represent our commitment to federal and provincial authorities, First Nations, communities and joint venture partners, and demonstrate our operational safety philosophy, environmental stewardship with respect to zero emissions and underwater noise mitigation.”
