SAAM Smit Canada has taken delivery of its first IMO Tier III-compliant escort tug as it prepares to service a new gas export terminal.
Uzmar Shipyard has delivered Tsimshian Warrior, a tug with 13 knots top speed, which will support ships berthing at an LNG export terminal in British Colombia, Canada. It is the largest escort-rated, multi-mission tug to operate along the entire west coast of Canada.
SAAM Smit Canada, a joint venture partnership between Dutch group Boskalis and Chile-headquartered SAAM, ordered this powerful tug in Q1 2018.
Tsimshian Warrior was built to a Robert Allan RAstar 3200W design. It has 83.5 tonnes of bollard pull ahead and was modified to suit extreme local conditions with upgraded systems.
Its main propulsion includes two Caterpillar Cat 3516E engines and Rolls Royce US255 controlled-pitch azimuth thrusters. The engines develop 2,525 kW of power and have selective catalytic reduction systems to comply with IMO Tier III emission requirements.
Tsimshian Warrior can perform all ship-handling duties, including emergency duties, berthing, unberthing and escorting LNG carriers in all weather conditions. It has multiple safety features that are only required on tugs dedicated to LNG terminal operations. These include gas detection and explosion-proof deck equipment.
This tug is fully equipped for LNG terminal stand-by roles with a FiFi1 external fire-fighting system and heavy-duty escort towing equipment suitable for rescue towing missions.
SAAM Smit Canada and Robert Allan collaborated with British Columbia Coast Pilots, Pacific Maritime Institute, Towing Solutions Inc and Lantec Marine Inc in developing the design and performance characteristics of Tsimshian Warrior.
This was developed and tested before construction begun to meet a stringent set of performance requirements. The partners used multiple real-time full mission bridge simulations at Pacific Maritime Institute to verify the design. These requirements include a bollard pull of more than 80 tones and indirect escort forces of up to 120 tonnes at speeds of 10 knots.
Uzmar delivered Tsimshian Warrior on 22 February 2019.
Vessel emissions and compliance with IMO Tier III requirements will be discussed at Riviera Maritime Media's Americas Sulphur Cap 2020 Conference, in Houston, on 5-6 March
