Investment in Design

Immingham Dock, on the U.K. east coast, and the design is distinguished by the efficiency of cargo access and cargo working to the four freight decks. It is also unusual, in a shortsea RoRo context, for the adoption of a single-screw, single main engine installa- tion, using a two-stroke 9L60MC-C diesel from MAN

B&W.

The quartet of Turkish newbuilds on order at

Flensburg have each been dimensioned for total freight stowage on four decks corresponding to 255 trailers of 13.6-m length, and will strengthen UN RoRo's servic- es between Istanbul and the north Adriatic, an impor- tant conduit for Turkish hauliers and shippers. FSG delivered six ro-ros to the Turkish operator during 2000-2002, and the latest series will provide an advance in linear capacity on similar dimensions to the 3,256 lane-metre UND Ege type. Unlike the single dri- veline and low-speed diesel plant employed in the new

DFDS generation, the Turkish ships have been speci- fied with two medium-speed diesels driving control- lable pitch propellers through reduction gearboxes.

Global Scope to Enviro Rules

At long last. Annex VI to IMO's Marpol Convention has been ratified by the requisite number of countries representing at least 50% of world tonnage, opening a new chapter in environmental regulation. Samoa's rat- ification took the number of accepting states to the 15 needed to trigger implementation, such that interna- tional limits on nitrogen oxide and sulfur oxide emis- sions from shipboard machinery will enter force on

May 19, 2005.

Annex VI also prohibits deliberate emissions of ozone-depleting substances, including halons and chlorofluorocarbons(CFCs).

Many have welcomed the prospect of a firm date for the introduction of international regulation on air pol- lution from ships, fearing a proliferation of local or national rules, a process that is already well in train.

Nonetheless, the criteria laid down under the engine speed-related nitrogen oxide (NOx) emissions curve formulated by IMO established a common basis for the design optimization process needed to improve the environmental standing of marine diesel engines.

Moreover, the parameters laid down under Annex VI provide just a starting point for the industry, as pro- gressively tougher international limits can be expected to be mandated in the years to come.

The regulations include a global cap of 4.5-percent sulfur content of fuel oil, and contains provisions for special 'SOx Emission Control Areas'(SECAs), in which the sulfur content must not exceed 1.5-percent.

Alternatively, ships must fit an exhaust gas cleaning system, or use other technological means to restrict

SOx emissions. The first SECA will be the Baltic Sea, with effect from 2006. It is anticipated that the North

Sea and parts of the English Channel will be designat- ed as SECAs in 2007.

Renewing the R&D Base

One hundred years on from the opening of the

Felling site on Tyneside for the production of special- ist marine paints. International Coatings' parent group has ploughed Euro 4-million into the creation of a new, purpose-built research and development laboratory at the U.K. premises. The project forms part of an ongo- ing program entailing expenditure of over Euro 10-
