their injuries sustained by the collision. From 2005 to 2006, the S-class ferries underwent major refits. In 2017, it was announced that the two S-class ferries would undergo a $140 million conversion to a dual-fuel system to allow the vessels to use liquefied natural gas as fuel in an effort to reduce greenhouse gas emissions. Further modifications during the conversion included the replacement of navigation and propulsion systems and a general overhaul. Passenger areas were modified as well. Spirit of British Columbia was the first to undergo the conversion at the Remontowa Ship Repair Yard in Gdańsk, Poland, between 2017 and 2018. Spirit of Vancouver Islands retrofit began in September 2018 and the vessel returned to service in April 2019. The conversion of Spirit of British Columbia earned BC Ferries the Shippax Retrofit Award, which identifies innovation in the ferry industry. References Ships built in British Columbia Ferry classes
