Today, Alfa Laval is a well known name within the key technology areas of heat transfer, separation and fluid handling. The company was founded on a single brilliant invention, and innovation remains at the heart of everything that they do. With more than 2000 patents, they provide worldwide solutions in areas that are vital to society.
Headquartered in Hamburg, Germany, Buss Shipping, the shipping arm of the worldwide maritime logistics service provider Buss Group, is a container ship operator with 20 feeder ships and a strong chartering business. To meet the requirements of today’s charter market, the company is focusing on the sustainable modernisation of its existing fleet.
Buss Shipping will soon install Alfa Laval PureSOx exhaust gas cleaning systems on two of its container vessels. The SOx scrubbers will secure valuable fuel economy in a competitive charter market. As a key step in this process, hybrid Alfa Laval PureSOx systems will be retrofitted on board the vessels Condor and Corsar. Both are container feeders of 1025 TEU that operate exclusively in Emission Control Areas (ECAs). Since they frequent the low-alkalinity waters between Rotterdam and St. Petersburg, as well as ports like Hamburg with zero-discharge requirements, a scrubber with closed-loop mode was a necessity.
“The hybrid PureSOx systems on the Condor and Corsar will provide emission compliance with maximum flexibility and fuel economy. This will uphold the competitiveness of our offer to charter customers,” says Torben Kölln, Managing Director, Buss Shipping.
The Condor and Corsar will each receive a hybrid PureSOx system with multiple inlets, connecting the main engine and two auxiliary engines to one U-design scrubber. In contrast to earlier systems with multiple inlets, the inlets will now lead into a single scrubber jet section – an advance in construction that will make the scrubber even more compact.
“The PureSOx solution was well engineered and allowed a sophisticated integration of the scrubber system into our container feeder ships. The custom construction let us avoid major modifications inside the vessel, which together with the pre-outfitting gave us a short installation time. All those factors contributed to a competitive price,” says Christoph Meier, Project Manager, Buss Shipping.
For the engineering of the PureSOx systems, Buss Shipping GmbH & Co. KG cooperated with SDC Ship Design & Consult GmbH. Detailed engineering was handled by the shipyard German Dry Docks GmbH & Co. KG, which will install the systems following deliveries by Alfa Laval in January and February 2016. “The work between Buss Shipping, Alfa Laval, the shipyard and the engineering consultant has been smooth and productive. Alfa Laval’s scrubber design and project management experience, together with the strong cooperation from the rest of the team, will ensure a reliable outcome for Buss Shipping,” says Mark Aarbodem, Project Manager at Alfa Laval.
“All parties have worked together to arrive at a compliant solution that will benefit our charter operations. Rather than paying for expensive fuel, our container vessels will be able to serve charter customers at a competitive price – while still retaining our margins,” says Kölln.
