On board the Royal Navy Ton class coastal minesweeper Glasserton (1953) looking forward, to port and slightly up from the port side of the forecastle deck abaft the funnel while she is refuelling from the Royal Fleet Auxiliary tanker Grey Rover (1969) under way off Gibraltar in early 1980 during exercise Test Gate. The port derrick post of the Glasserton is in the centre and the port bridge wing is on the right. The men in charge of the refuelling are wearing wet weather gear, hard hats and life jackets. Only the bow of the Grey Rover (1969) is in the picture.
