Following the dual-fuel LNG ferry F.-A.-Gauthier, LR is classing two more LNG-fuelled ferries for Canada’s Société des traversiers du Québec (STQ).
he 92-metre dual-fuel ferries will
serve the vital Tadoussac – Baie Sainte
Catherine route across the mouth of
the Saguenay River, and will be powered
by Wärtsilä gas engines. They represent
new generation technology to support
STQ’s public service mandate and vision
to support society by offering effective
transport infrastructure in Québec.
The ferries are being constructed at Chantier Davie in Québec – Canada’s largest shipbuilding facility – and will have Wärtsilä 20DF units of varying sizes in arrangements that provide total redundancy under ‘safe return to port’ requirements. Other factors include ice protection to cope with the harsh winter conditions – the ferries have podded propulsion units with ice class IAS while the hull is ice class 1A.
We helped STQ complete a full risk assessment to decide on the ships’ dual fuel arrangement.
Transport Canada, the federal
authority for transportation, which
has the responsibility for making vital
regulatory framework decisions is also associated with this project. Lloyd’s
Register plays an active role in helping
develop risk management approaches
and providing clarity to help with the
regulatory process. One of the vital
steps being taken is to train the crews
and shore staff to ensure that they are
equipped to deal with LNG.
The needs of the local communities, visiting tourists and environment have been taken into account as well. The emissions from the ferries will be free of particulates and sulphur, and will have vastly reduced NOx. And noise and vibration has been addressed to help ensure the whales which visit the area are disturbed as little as possible.
Client testimonial - Benoit Cormier, Project Management Office Director for STQ
"We will operate these
vessels for many years – perhaps 35 to
40 – so we wanted to try and find the
most modern technology and to meet
the requirement for cleaner solutions."
