Service record
Operations:

Tidepool had a long and busy life in the fleet. The ship participated in both the Cod Wars and the Beira Patrol during the 1970s. In 1982 when the Falklands War broke out Tidepool was on its way to Chile to be disposed of. The ship was temporarily reclaimed by the United Kingdom and was finally handed over to the Chilean Navy on 13 August 1982 and renamed Almirante Jorge Montt.

Design and construction

edit

Tidepool had a normal complement consisting 110 Royal Fleet Auxiliary personnel with provision for up to 24 Royal Navy personnel. She was designed with abeam replenishment at sea rigs, which had automatic tensioning winches and she had an astern fuelling rig. Tidepool was also fitted with a single spot 50 x 70 ft helicopter deck, designed to be capable of handling the Royal Navy Westland Wessex helicopters used at the time. She had hangar facilities for a single helicopter and could support aviation refuelling. The ship was built to carry 9,500 tons of Furnace Fuel Oil, 5,500 tons of diesel oil and 2,000 tons of avcat and the forward hold could take dry cargo.[4]

The construction of Tidepool was carried out by the shipbuilder Hawthorn Leslie, at Hebburn. The ship was laid down on 4 December 1961 and launched twelve months later on 11 December 1962.[1] She displaced, fully loaded, 27,400 tons, was just under 584 ft in overall length and was capable of 17 knots.[3]

Along with air stores support ship Reliant and the armament support ship Resurgent,[6] Tidepool was deployed on the Beira Patrol in the Mozambique Channel in March 1966, to enforce United Nations sanctions against Rhodesia. The RFA provided support for initially a Royal Navy aircraft carrier and two frigates.[7] On this deployment Tidepool claimed the record for the longest time in the Mozambique Channel at fifty-three days,[8] and was continuously at sea for eighty-one days.[9]

On 25 January 1977 Tidepool left HMNB Devonport as part of Task Group 317.5, for an Atlantic deployment led by the Royal Navy’s converted helicopter cruiser Tiger,[1] in the company of the RFA’s small fleet tanker Green Rover and the fleet stores ship Tarbatness. She returned to the United Kingdom in May.[2]

On 5 September 1977, along with RFA’s small fleet tanker Grey Rover, the ammunition, explosives and stores supply ship Regent and the fleet stores ship Tarbatness, Tidepool departed HMNB Portsmouth involved in Task Group 317.7, again supporting the helicopter cruiser Tiger, the task group’s flagship,[1] and accompanied by the Royal Navy's Rothesay-class frigate Rhyl. The deployment was for seven and half months, and covered Australia and the Far East. She returned to the United Kingdom on 20 April 1978.[2]
