Breakthrough order for Hamworthy Krystallon

Italian shipowner Ignazio Messina & C. has selected Hamworthy Krystallon seawater exhaust gas scrubbers so that four new 45,000 dwt RO/RO ships burning residual fuel oil can meet EU regulations demanding sulfur emissions equivalent to just 0.1 percent fuel sulfur content.

Hamworthy says this is the first commercial order for technology enabling owners to meet new EU regulations on emissions without switching to high cost distillate fuels.

The ships, under construction at Daewoo Shipbuilding and Marine Engineering, South Korea, will be available to trade worldwide, although their principle area of operation will be in the Mediterranean Sea.

EU directive EC 2005/33, introduced in January this year, imposes a 0.1 percent limit on sulfur emitted by ships in EU ports, achievable through burning low sulfur content fuel (MGO) or fitting abatement technology.

"These ships are being built with the highest environmental standards in mind," said Dott. Ing. Enrico Allieri, Technical Director, Ignazio Messina. "This is demonstrated by the fact that they are the first ships of their type to feature RINA's Green Plus notation. The installation of seawater scrubbers to control emissions is critical to our overall environmental objectives. In addition it makes great economical sense."

Each ship will feature five scrubbers, consisting of four units for the auxiliary engines (each 2 MW) and one unit for the auxiliary boiler (2.5 tons steam per hour). All scrubbers will be housed within the casings of the ship's exhaust stack. Equipment will also include a control system, combined wash-water treatment plant and a new range of super duplex stainless steel pumps supplied by Hamworthy's Singapore plant. All emissions will be continuously monitored.

Burning fuel with a sulfur content of up to 4.5 percent, the ships will nonetheless be able to meet the 0.1 percent EU's in-port emissions requirement. Seawater scrubbing will also have a substantial impact on particulates emissions.

As part of the build project, provision is also being made for the future installation of scrubbers to cut emissions from the ships' main engines, in line with operation in the Emissions Control Areas defined by IMO, where maximum sulfur content in ship fuels is capped at 1 percent from July 1, 2010, falling to 0.1 percent from 2015.

Sigurd Jenssen, Managing Director, Hamworthy Krystallon Ltd, said: "This is an important milestone for Hamworthy Krystallon, but also for exhaust gas scrubbing in the marine industry in general. Messina, DSME and Hamworthy are all leading names in the shipping industry, demonstrating our collective view that seawater scrubbing will become a mainstream marine technology."

To date, Hamworthy Krystallon seawater scrubbers have been successfully trialled on the P&O Ferries ship Pride of Kent and on the Holland America Lines cruise ship Zaandam. They have also been installed in land-based facilities in Greece and Japan.

Hamworthy beat off a number of suppliers to secure the breakthrough deal. "Our choice was based on the track record of the Hamworthy Krystallon system, but also on the support available from a global marine group like Hamworthy in committing to technology that is new to us as a shipowner," said Dr. Allieri.

"Of course, we take pride in securing an industry first," said Mr Jenssen. "However, we also know that viable competing technologies will be critical to the wider uptake of seawater scrubbing by other forward looking shipowners."
