Sludge Buoy

Sludge Buoy™ System (SBS) is installed onboard a ship inside the sludge oil tank or bilge water tank. Sludge Buoy (SB) is a variable height oil skimmer which means it will follow the liquid surface up and down. Maximum working length is 2.0 meters.

Inside the tank SB will always stay at the immediate surface. SB takes suction 15 - 20 mm from the top liquid layer. SB will follow all motions of the ship and will always be at a 90° angle to the content inside the tank, thanks to the Cardan type fastening device. SB is easy to install and the installation is done by the ships own crew while the tank is anyway open for normal inspection and cleaning. If it is not possible to weld inside the tank a special clamp is fitted without any welding. Existing piping systems are also recommended to be used as far as possible. There is no special maintenance on SB beyond cleaning it when regular tank cleaning is conducted. The suction hose is recommended to be changed annually or semi annually depending on the temperature inside the tank.
