TRV Trevally (802)

TRV Trevally (802) was one of three Torpedo Recovery Vessels operated by the Royal Australian Navy (RAN) and Defence Maritime Services (DMS). Ordered in 1969, the vessel, originally identified as TRV 254, was completed in 1970 and assigned to the naval base HMAS Waterhen (naval base) in Sydney. The ship received a name and the pennant number "TRV 802" in 1983. In 1988, the three vessels were sold to DMS. Trevally remained at Waterhen under DMS control. Trevally was active in DMS service as of 2007.

Design and construction
The class was ordered in 1969 as replacements for World War II-era torpedo recovery vessels.

The vessels each have a full load displacement of 94 LT, a length of 26.8 m, a beam of 6.1 m, and a draught of 1.1 m. Propulsion machinery consists of three GM V8 diesels, which supply 890 hp to the three propeller shafts. Top speed is 9.5 kn, and the vessels have an endurance of 63 hours at 8 kn. Each Fish-class vessel can recover up to eight torpedoes via a watertight stern gate. They are unarmed, and their sensor suite is limited to an I-band navigational radar. Nine personnel make up the crew.

Three vessels were built at Williamstown Dockyard for the Royal Australian Navy, with TRV 254 completed in September 1970.

Operational history
On entering service, TRV 254 was assigned to the naval base HMAS Waterhen (naval base) in Sydney. In addition to torpedo recovery, the vessels were used as dive tenders and as training vessels for the Royal Australian Naval Reserve.

In 1983, the boats were named and redesignated, with TRV 254 become Trevally, with the pennant number "TRV 802".

In 1988, the three vessels were sold to DMS. As part of the company's role in providing maritime support for the RAN, Trevally was assigned as a tender to Waterhen. Trevally was still active with DMS as of 2007, but was no longer listed as active by 2012.
