History

Tyr was built at Voldnes Skipsverft in 1981 and was used as an offshore standby-ship in the North Sea under the name MS Standby Master, yard number 31. The Royal Norwegian Navy took her over in December 1993, and Tyr went through a comprehensive rebuilding and modernization program between 1994 and February 1995 at the Mjellem & Karlsen shipyard in Bergen. Under the rebuilding Tyr was equipped with new thrusters, the bridge was expanded and a mine hangar was built on the aft-deck, and new hydraulic equipment was installed on the work-deck. Tyr was fitted with tactical systems, and was equipped with a Scorpio ROV. The furnishings were also modernized.^{[citation needed]}
