The EM-85 'Orca' class is large size, multi-purpose fleet replenishment ship that can transfer stores and liquids to ships at sea. With the advanced transfer equipment the ship can either resupply vessels abeam whil at sea, at a port facility as well as using vertical replenishment with its helicopters.
The four dual-purpose replenishment rigs fitted amidships enable the EM-85 to replenish two warships with both fuel and stores simultaneously. Fuel transfer is accomplished by suspending a hose from a tensioned cable, the jackstay, which runs from the supply ship to the receiving warship. The hose is fitted with a quick-coupling probe to mate with the receiving point on the warship. Once the hose has been connected,the EM-85 is able to pump fuel across to the receiving ship. During a stores transfer the jackstay supports a 'traveller', a travelling hoist to which loads of up to 2t may be coupled.
As well as the main replenishment rigs, teh ship is also fitted with an additional refuelling rig, called a Hudson Reel, at the stern. Stern refuelling is not as efficient as beam replenishment, but it is safer in severe weather conditions as the ships are less likely to collide.
The EM-85 class is also fitted with a two-spot flight deck, a hangar and maintenance facilities for five EA-24 (http://www.nationstates.net/forum/viewtopic.php?t=40824) sized helicopters. This gives the ship an enhanced capability to re-supply warships in a task group by a technique called vertical replenishment (VERTREP) which involves using helicopters to ferry supplies from ship to ship. VERTREP may be used re-store a vessel that does not need to take fuel onboard. In addition the helicopters can provide an ASW and ASuW capability to the ship which increases its organic self-defence.
The EM-85 is equipped with the full set of navigation and communications equipment, powerful diesel power plants, air-conditioning and ventilation systems to provide efficient operation in any climatic conditions and NBC chemical protection systems as well as a radiation de-contamination facility. It can be operated in sea conditions up to Sea State 10.
