Since September, Tidesurge has covered over 13,500 miles—equivalent to sailing halfway around the world—delivering essential fuel to Royal Navy and Allied vessels on the front line.
The ship has transferred enough fuel during this period to fill an Olympic-sized swimming pool or more than 40,000 family cars, ensuring that the ships remain on task without needing to return to port.

Despite the routine nature of these operations, the process of Replenishment at Sea (RAS) is a complex and hazardous task. As Tidesurge’s Third Officer Josh Sylvester explained, “A replenishment at sea is a dangerous and challenging evolution for all involved… Pumping a volatile commodity through a replenishment rig suspended across a span of thrashing sea… takes skill, concentration, and experience.”
The RAS manoeuvres require careful coordination between the tanker and the warship, with both vessels separated by about 42 metres, travelling parallel at the same speed. These operations often last several hours and can take place at any time, in any weather, to ensure the warships can continue their missions.
In addition to fuel, Tidesurge delivered dry stores, such as food and essential supplies, either through jackstay transfers or vertical replenishments carried out by NH-90 helicopters.
The crew of Tidesurge also had the chance to experience the Arctic, with some members crossing the Arctic Circle for the first time, participating in the traditional ceremony led by ‘King Neptune’. The voyage also provided the crew with breathtaking views of the Northern Lights, marine wildlife, and icebergs, as described by Sylvester: “Cruising over 12,500 nautical miles… has provided the ships’ company with some outstanding displays of natural beauty, including the Northern Lights… and a remarkable vantage point for spotting icebergs.”
Tidesurge will soon return to Portland for maintenance and a crew change before continuing her duties at sea.
