As part of Seahorse Standard's duties while based at Stirling, she was tasked as the submarine escape and rescue support vessel. With the rescue ship MV Besant becoming operational in July 2015 and the planned completion of MV Stoker in early 2016, Seahorse Standard will no longer be needed for the role, and will likely be reassigned to eastern Australia.
