propulsion control system, and all shaft seals and bearings. The contract also includes the supply of an integrated automation system for not only the machinery spaces, but the entire ship. With an overall length of 110m and an18m


beam, the single screw tanker will be equipped with a propulsion arrangement capable of delivering a ship speed of up to 13.4knots, at design draught condition. Willy Perng, Wärtsilä’s sales manager in Taiwan,


said that Wärtsilä had a long-standing relationship with CPC, which already has 12 sets of Wärtsilä two-stroke engines installed in its fleet. “The contract marks a significant milestone for


Wärtsilä in that it is the first time we have dealt with the Jong Shyn shipyard. It is also the first time we have supplied CPC with new four-stroke main engines, and the first ever ship design we have sold in Taiwan,” said Mr Perng. Wärtsilä said the the acquisition of CWA


demonstrated the group’s commitment to becoming the leading provider of ship design services in specialised areas, including offshore and special vessels, as well as selected merchant vessels.


Business Hamworthy snaps


up Greenship Hamworthy has acquired Greenship B.V., of The Netherlands, the developer of the Sedinox ballast water treatment technology. The initial deal, worth €2 million, will be augmented with a further €5 million once the system receives formal regulatory approval, anticipated later in 2009. The acquisition is being funded entirely from Hamworthy’s own cash reserves. Based in Groningen, Greenship is a privately


owned business specialising in the emerging ballast water treatment for ships market, which is being driven by international environmental regulations. Its system involves a combination of separation and electrolysis. Sedinox involves no ‘active’ chemical process and has no moving parts, and is installed in a ship’s engineroom, with power consumption being no more than. 2kW per 100m3


of water. The system, which is scalable from capacities


of 100tonnes per hour to 5000tonnes per hour, has been specified in a 200tonne per hour configuration for use onboard two ships operated by Dutch owner Chemgas, for delivery in the first half of 2009. Four patrol vessels operated by the Royal Dutch Navy will also feature Sedinox.

For the year ended 31 December 2008 Greenship


reported turnover of approximately €500,000. Backed by Hamworthy, the technology is expected to develop quickly as a commercial proposition. Hamworthy chief executive, Joe Oatley, said:


“Ballast water treatment is an exciting global opportunity underpinned by strict international environmental regulations. The acquisition of Greenship complements our existing water systems business and is consistent with our strategy of expanding the Group’s technological base in long-term growth markets.”


Coatings Savings drive


GNV conversions Cruise ferry operator Grandi Navi Veloci (GNV) reckons to be saving a substantial amount of money after applying silicone-based foul release coatings to the hulls of its ships. Starting from 2005, the Mediterranean operator


has progressively converted all of its vessels at maintenance and repair dry docking to the biocide free, foul release system, Intersleek. Intersleek 700 was first applied to the 32,700gt,


23knot cruise ferry Majestic, and has subsequently been applied to Fantastic, Splendid, Excellent and Excelsior. In January 2009, after 40 months service in one


of the world’s most severe fouling environments, Majestic drydocked at the Ente Bacini Shipyard, Genoa. The hull was described as being “in excellent condition, smooth, glossy and with minimal mechanical damage”. Only 30 litres of Intersleek was required for touch-up on the bow before the vessel returned to service. Bruno Dionisi, GNV technical consultant, said:


“On average this product provides undisputed advantages which, in our case, are represented by a bunker saving of around 6%-7%, a significant reduction in time spent in drydock and hull washing costs and, most of all, an overall saving on the complete economic paint scheme which can be evaluated at around €100.000”. Even before Majestic returned to drydock,


fleet fuel savings had already influenced GNV’s decision to coat two further ships (La Superba and La Suprema) with Intersleek 900 - International’s latest fluoropolymer-based foul release technology. La Superba, completed in March 2007 is the largest cruise ferry in the world and was the first vessel in Italy to be coated with Intersleek 900. Intersleek 900 has now been applied on over 50 passenger vessels worldwide.
