HMS Enterprise Completes Five-Year Maintenance Period

HMS Enterprise has emerged from dry dock sporting a new paint job after a major five-yearly upgrade. The Plymouth–based survey ship’s docking maintenance period in Falmouth included improvements to the hull, engines, living conditions and the multi-beam hydrographic sonar.

The new ‘Sealion’ hull coating (which feels rubbery and slimy to the touch even when dry) reduces marine growth and the risk of mechanical damage, both of which ensures a smooth hull surface that reduces drag and hence lower carbon emissions as fuel savings are made.

At the same time a 30,000 hour overhaul of main generators ensured they are in prime condition to carry out operations anywhere in the world including the coldest seas. Another engineering feat was the 10-yearly overhaul, the first since the ship was built, of the Azipods.

Satellite communications capability has also been refreshed with voice and data given an increased sea-going bandwidth.

The upgraded multi-beam echo sounder now provides up to 4,000 soundings per second, giving minute level of detail when updating charting and improving navigational safety for the Royal Naval and merchant marine fleets alike. The improved sonar places HMS Enterprise at the forefront of global hydrographic capability.

All of the above will be put to the test during the next six months, with ongoing trials, Joint Warrior exercises in the Atlantic and basic operational sea training, pushing the ship to it’s operational limits in the training environment before deploying in 2014.
