“We save 3-4 hours on every discharge operation”, says Fredrik Farsén, Technical Manager at Ektank AB, who is very happy with the investment in Svanehøj’s automatic super stripping system.
If a product/chemical tanker is equipped with a conventional stripping system, up to 20 litres of liquid cargo is left when the tank is stripped. If, however, the ship is equipped with Svanehøj’s integrated super stripping system, less than half a litre will be left in the tank. This reduces cargo waste to a minimum and means that the ship’s crew can avoid having to spend valuable time wash-ing the cargo tanks to get the ship ready for the next job.
The prospect of improving efficiency, saving costs and minimising operation time in port was the reason why, in 2018, Ektank AB chose to invest in Svanehøj’s super stripping system for the construction of the two product/chemical tankers EK Stream and EK River.
The system is more expensive than a traditional strip-ping system, but according to Technical Manager Fredrik Farsén at Ektank, the investment is worth every penny.
“All cargo being stripped is dis-charged ashore prior to departure. There are almost no remains on board (ROB) following the stripping operation. The stripping system can be managed by just one person, and we save 3-4 hours on every discharge operation compared to a conventional system”.
This is the first time that Ektank has installed Svanehøj’s super stripping system, but probably not the last. The system has met all expectations – and more.
“Compared to other vessels in the fleet, we avoid 2-3 cbm of ROB for every discharge operation”, says Fredrik Farsén.
Svanehøj’s super stripping system is installed as independent units in every cargo tank. A small vacuum tank is mounted in the cargo tank directly on the pipe stack of the deepwell pump and connected via pipes to a control unit (manual or automatic) on deck. This avoids containment of cargo, unlike other solutions on the market where the cargo is sucked into a central vacuum tank on deck.
