"Aleut" took over guarding, and St. Petersburg was given a 24-hour ecological patrol. The Rossmoreport fleet has been replenished at the Aleut Egg Water Collector. The vessel was built at the Okskaya Shipyard, and before the end of the year it will go on duty in the great port of St. Petersburg. Flood water is a liquid that accumulates right at the bottom of the ship's hull: flood water, condensation from machines and pipes, fuel residues and oils. So "Alaot" is a floating reception and treatment facility. It collects water containing oil from ships, settles and separates it: residual oil is sent to storage on board, and the ship transports the purified water to shore or releases it where permitted. The ship's hull is reinforced with ice, so it can operate all year round.
