Wärtsilä has received a major order from Swedish shipowner Laurin The contract, signed in March 2008, calls for six Wärtsilä Senitec M1000 oily water separation units to be delivered in mid April 2008.
The units will be retrofitted to six of the company's vessels and will replace existing systems, thus upgrading their oily water treatment performance to market-leading standards. The order also includes six SolidPac units to handle solid residues.
Wärtsilä earned this order on the basis of the separators' discharge performance, the sustainability of this performance over time, their simplicity of operation, and the very short payback time of less than one year. Approval of the separators by the US Coast Guard was a prerequisite, as most of the ships to be retrofitted are based in the .
Wärtsilä Senitec oily water separators, with a discharge of less than 1 ppm (parts per million) of oil in the water, offer the best performance available anywhere today. With environmental considerations becoming an increasingly critical factor, they are well qualified to serve a wide and growing market. The separators can be installed, with equal convenience, either in newbuilds or as retrofits. Their performance has been well verified, for instance, in the Finnlines fleet.
The Wärtsilä Senitec M1000 unit fulfils all local and global environmental requirements, and US Coast Guard tests verified an oil-in-water discharge content of less than 1 ppm consistently over prolonged operation. The unit is designed and built for continuous operation, and is capable of cleaning 1 m3/h, or 24 m3/day, of sludge and bilge water. The optional SolidPac accessory enables removed solids to be treated and de-watered for easy, separate disposal rather than merely returning them to the sludge tank.
Where larger volumes of sludge and bilge water are in question, the Senitec M-series includes the M2500 unit capable of cleaning 2.5 m3/h. More information and full details on the full range of Wärtsilä oily water separation equipment can be obtained by visiting www.wartsila.com/senitec
