New flue gas technology to be tested on DFDS ferry
DFDS ferry Tor Ficaria is being fitted with a scrubber in its funnel to remove sulphur-containing compounds from its flue gases
A rather special funnel will be sported by DFDS ferry Tor Ficaria as it starts plying the route between Gothenburg (Sweden) and Immingham (UK) this month. It might not look any different from the outside, but installed within it there will be a device called a scrubber, which is designed to remove sulphur-containing compounds from flue gases, reports professional journal Ingeniøren (The Engineer).
Basically a kind of shower cabin that streams water down through the upward flowing flue gases, the scrubber is reportedly the largest of its kind ever fitted to a ship and will be tested by experts from marine engine manufacturer MAN Diesel, Aalborg Industries, and DFDS itself.
The scrubber has the clever feature of being able to use either sea water or fresh water. The advantage of this double system is that when the ship is close to shore, it can switch to using fresh water which is recycled and not discharged, and when out at sea it can switch to using directly dischargeable sea water and at the same time clean and discharge the used fresh water.
Besides the environmental perspective, there is a commercial advantage in this DFDS initiative. In the North Sea and the Baltic Sea, ships can only use low-sulphur fuel oil, which is significantly more expensive than traditional fuel oil which contains about 4.5% sulphur.
If the tests on the scrubber-equipped Tor Ficaria show that there are no extra sulphur emissions from using the higher sulphur content fuel, there is a chance that the vessel could gain approval to use the cheaper fuel and thereby gain a significant economic advantage on its competitors.
