Astern Reel Refueling at Sea

Kongsberg Maritime produce refueling at sea astern reels to provide an additional dimension to underway replenishment for modern navies. Mounted on the aft of the vessel it gives unsurpassed refueling capability in rough or stormy seas when the abeam method is not possible. By removing the requirement for the vessels to be in close proximity to each other, the refueling process is made safer under these otherwise dangerous conditions.

Capable of supporting multiple hoses, the astern reel gives the added benefit of being able to provide a range of different liquid mediums to the reception vessel, whilst being contained in a relatively compact deck machinery envelope.

To enable the layflat hoses to stow correctly, the astern reel assembly is provided with an air pressure driven pig launcher and blow down system. This ensures the hoses are left empty and clean during storage on the drum.

A manually controlled oscillating hose spooling carriage is fitted to ensure that the hoses are paid out and recovered smoothly and without damage. The hose carriage is driven mechanically by a separate motor. Only one of the two hoses may be deployed at a time so the spooling carriage can be used on any of the hoses fitted to the drum. An associated electrical starter panel is also supplied which is mounted in an enclosed compartment position.
