YSR - Sludge Removal Barge

YSR is a non-self-propelled sludge removal barge 110 foot long by 34 foot beam, designed for use in cleaning fuel oil or other tanks or compartments of any type of vessel of oil, sludge, water and miscellaneous foreign matter. It may operate in combination with an oil storage type barge (YOS) or independently.

The sludge removal system utilizes hot salt water discharged through a hose and nozzle from the wash down pump for tank cleaning, and is supplemented by a steam hose for preliminary steaming out and use in conjunction with scrapers or brushes to loosen heavy viscous deposits. Oil, water sludge, etc., is then picked from the ship's tanks and deposited into one of four vacuum tanks by a vacuum process utilizing the vacuum pump and associated hose and nozzle. The foreign material is then discharged by compressed air into the sludge settling tanks within the barge or to a separate oil stowage barge such as a YOS. In the event the sludge settling tanks are used, a sludge pump is provided for use in discharging the sludge from the sludge settling tanks overboard at a suitable dumping site.

The barge is capable of being towed on an ocean voyage for delivery to an overseas base.

No galley or berths are provided. Normal working complement consist of ten personnel (eight tank cleaners, one fireman, one engineer).
