These residues result in some cargo loss, so cleaning guns are fitted within the tanks. During discharge, about 10% of the cargo is recirculated under pressure through these rotating guns to wash down the clingage (residue of text/html 2025-01-20T10:00:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://mauricepointner.at/dokuwiki/doku.php?id=0_public:environmental_and_safety:stripping:eductor&rev=1737367253&do=diff Eductor * used on tankers of all types and sizes.Tanker Chartering The use of eductors is another method of cargo tank stripping.

Priming and capacity regulating systems convert any centrifugal pump into a self-primed unit. As the system is capable of emptying the cargo tanks entirely, no separate stripping pump is needed. text/html 2025-01-20T10:00:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://mauricepointner.at/dokuwiki/doku.php?id=0_public:environmental_and_safety:stripping:pumps&rev=1737367253&do=diff Vessel Pumps Cargo pumps are placed at the bottom of a ship because the height that a pump can push a liquid is limited only by the power of the pump.Tanker Chartering A tanker uses its own pumps for discharging cargo and loading and discharging ballast, while cargo loading is carried out using shore pumps. text/html 2025-01-20T10:00:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://mauricepointner.at/dokuwiki/doku.php?id=0_public:environmental_and_safety:stripping:stripping&rev=1737367253&do=diff Cargo Stripping text/html 2025-01-20T10:00:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://mauricepointner.at/dokuwiki/doku.php?id=0_public:environmental_and_safety:stripping:vac-strip&rev=1737367253&do=diff Vac-Strip Some vessels are íìtted with Vac-Strip, a proprietary system that allows the large centrifugal pump to drain a cargo tank completely.
