Seen through typical Greenock drizzle, the Canadian auxiliary oil replenishment ship PRESERVER was part of a four-strong Canadian contingent arriving on Friday to take part in Joint Warrior 092. Unlike the other three ships, PRESERVER went to anchor off Greenock before berthing alongside Ocean Terminal later in the day once commercial shipping had completed container operations and had sailed. PRESERVER, which was built by Saint John Shipping at Saint John in New Brunswick, was commissioned into the Canadian Navy in 1970. She is 172 metres long, and has a deadweight of 24,700 tonnes. She is due to undergo a major refit in 2010-11.
