CLASS SURVEY VESSELS
order placed with Vosper Thorneycroft in 2000 for two new Hydrographic
Vessels resulted in a 'through life contract' covering support for 25 years. The ships will work
with the fleet worldwide, supporting mine warfare and amphibious tasks besides
carrying out specialist hydrographic activities.
with HMS Scott, the ships are planned to work over 300 days
per year at sea.
The Royal Navy's Surveying Service has been
operating throughout the world since the formation of the Hydrographic
Department in 1795 and the information from oceanographic surveys is used for
producing Admiralty charts and nautical publications which have a world-wide
sale and are used by ships of many nations.
The Surveying Flotilla consists of ocean-going
ships, coastal vessels and inshore craft. In addition to surveying in overseas
areas, many of the flotilla are constantly engaged in updating the charts
covering the waters around the United Kingdom.
To carry out these wide-ranging tasks the latest
surveying techniques are employed, including digitised echo sounders, side scan
sonar, automated plotting and recording of position, depth, gravity and magnetic
parameters. Satellite and inertial navigation systems are used when out of range
of shore-based position fixing systems.
