Finnish firm DeltaLangh Ltd says its exhaust gas cleaning system, or scrubber, has been successfully installed on Bore Ltd's M/V Bore Song.

The system has received confirmation of full compliance with SECA and IMO regulations (approved by Lloyd's register and TRAFI, the Finnish Transport Safety Agency), and is now confirmed as meeting all present and forthcoming requirements. The delivery was supplied on a turnkey basis by Deltamarin Floating Construction.

The True Hybrid Scrubber system allows both close and open loop operation. When M/V Bore Song sailed from the repair yard after 14 days dry docking, the open loop operation of the scrubber was in immediate use to clean the exhaust gases of the 12-megawatt (MW) main engine. While the vessel was trading final installations were completed, and the system can now also be used continuously in closed loop mode without time limits.

"The DeltaLangh Hybrid Scrubber was a choice when looking for a sustainable solution for the future. It has lived up to our expectations: minimum sludge handling, very clean outgoing water and in that respect minimum impact on the environment. The project was handled as a turnkey project, and I am especially pleased with the short installation time, which enabled us to keep our promise to our customer," said Jörgen Mansnerus, VP, Marine Management at Bore Ltd.

The DeltaLangh scrubber is lightweight and its energy consumption low. Another benefit is that zero discharge can be arranged without additional tanks on board.

As a major advantage compared to other available technologies, the water content in the output sludge in closed loop operation is described by DeltaLangh as being extremely low. This means that the waste is highly concentrated, and the amount that needs to be handled ashore is minimal. Thanks to the light weight, small size and efficient water treatment, no cargo capacity is lost.

According to DeltaLangh, the total energy efficiency is among the highest in the market today. The scrubber can be installed within a period of 14 days, as was the case with the M/V Bore Song.
