Hamworthy Krystallon lines up yard partners

05 Aug 2010

Following the first commercial order for exhaust abatement technology, Hamworthy Krystallon is finding shipyards eager to accelerate uptake of technology proven to cut sulphur emissions.

The decision by Italian owner Ignazio Messina to place first commercial orders for seawater scrubbers has prompted leading shipyards to align themselves with Hamworthy Krystallon.

The auxiliary engines and boilers on board four new 45,000 dwt ro-ro ships, to be built by Daewoo Shipbuilding and Marine Engineering will burn residual fuel oil in port but still meet EU directive EC 2005/33 port rules demanding sulphur emissions equivalent to just 0.1% fuel-sulphur content. The alternative is a switch to costly low sulphur content fuel.

Meanwhile, the Emissions Control Areas (ECAs) defined by IMO see maximum sulphur content in ship fuels capped in July this year at 1.0% and then 0.1% from 2015, or demand that owners burning heavy fuel oil commit to exhaust gas cleaning. Already, the Baltic Sea and the North Sea/English Channel are ECAs. U.S. and Canadian waters will follow in August 2012.

Weighing up the alternatives, the International Petroleum Industry Environmental Conservation Association said recently that producing enough low sulphur content distillates to meet the IMO 2015 target on main engines would be “difficult” and “significantly more expensive”. Meeting later targets would need “major refinery investment” and may “not be economically feasible”.

“On that basis the question is not why fit a scrubber on auxiliaries and main engines, but when,” said Hamworthy Krystallon managing director Sigurd Jenssen. Trials have shown that the company’s seawater scrubber cuts emissions from plant burning residual oil by up to 98%.

To date, Hamworthy Krystallon seawater scrubbers have been trialled on the P&O Ferries vessel 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.

Among those with experience of the technology is the UK’s A&P Group. A&P Falmouth managing director Peter Child said: “We worked on Pride of Kent and have a good idea of the work and costs involved. This places the A&P Group in a commanding position as the first choice for retrofit installations of the Hamworthy Krystallon exhaust scrubber. We look forward to the challenging times ahead and working with Hamworthy Krystallon in assisting the shipping industry to take the steps to comply with pending emissions regulations in the build up to 2015.”

Also alive to the opportunity is Sembawang Shipyard (SSPL), Singapore. SSPL technical director, Roy Varghese, said: “We are in the midst of discussions with Hamworthy Krystallon for a potential retrofit project on seawater scrubbers. Although the SWS system from Hamworthy Krystallon is new, the retrofit works involved are not something new for SSPL.”

Jenssen said that Hamworthy Krystallon was bringing expertise drawn from the wider Hamworthy group to bear on developing partnerships. Hamworthy Baltic Design Centre (HBDC) has developed installation lay-outs specific to ferries, car carriers, tankers and containerships. Using their knowledge of water systems, they can also help integrate ballast treatment, pumps, seawater scrubbers, waste water treatment and, in the case of tankers, inert gas IG systems.
