Carnival and Wärtsilä partner to develop environmentally friendly diesel
Common rail fuel injection and direct water injection will be used in a new generation of environmentally-friendly cruise ship diesels. Carnival Corporation has entered into a working partnership with the Finnish engine manufacturer, Wärtsilä NSD, to develop a smokeless diesel-electric propulsion system for cruise ships.

Prototypes of the new "project enviroengine,"engine are expected to be available later this year for laboratory testing..They are expected to be available commercially in 2001. Following successful completion of testing,
Carnival plans to utilize those engines on its future newbuilds.

According to Captain Jim Drager, Carnival's vice president of corporate shipbuilding, when complete, the enviroengine,installed in a diesel-electric propulsion system, will be one of the most environmentally friendly power plants available for ships.

"We have studied the attributes of gas turbines, which we are considering installing on several Carnival Corporation newbuilds now under contract, but still believe that eventually our current diesel- electric systems can be as environmentally friendly as gas turbine alternatives," he said.

Drager pointed out that because of efficiency, diesel-electric systems are far less taxing on precious fossil fuel assets and also emit substantially less carbon dioxide to the atmosphere.

According to Daniel Paro, Wärtsilä's group vice president - technology, the enviroengine is being created by combining "common rail technology" with a direct water injection system. Common rail technology uses an electronically controlled method to inject the precise amount of fuel at exactly the right time, resulting in greater engine operating efficiency and virtually eliminating smoke emissions.

Direct water injection reduces nitrous oxide (NOx) emissions by spraying water into the combustion chamber to cool it down immediately prior to injecting the fuel. Cooling down the chamber reduces NOx formation, which occurs at high temperatures. This method reduces NOx emission value to the same level as gas turbine NOx emissions.

Paro said, "The cruise industry has made its desire to have the most environmentally friendly ships sailing the seas well-known to its suppliers, and we are happy to have Carnival working with us on this exciting development. Since the mid-1980s, Wärtsilä NSD has spent more than $100 million (U.S.) on emission reduction research." He added that Wärtsilä will have spent more than $10 million (U.S.) on the enviroengine development before the prototype testing models are even built.

Drager said that in addition to being utilized on future newbuild orders, power plants on several vessels currently under construction, including Carnival Cruise Lines' "Spirit-class" ships and the Costa Atlantica, could be converted to the enviroengines. Additionally, Carnival plans environmental conversions on several of its existing vessels, including Holland America's Alaska-based ships.

"Direct water injection technology, and the smokeless feature of the new enviroengine, once perfected, will provide substantial environmental advantages," Drager said.


Liberian Senate suspends chairman of maritime committee
The Liberian senate has suspended its committee Chairman on Ways, Means, Finance and Maritime, reports Star Radio in Monrovia . (The station is staffed by Liberian journalists and managed by the Swiss NGO Fondation Hirondelle with financing from the U.S. Agency for International Development through the International Foundation for Election Systems. Additional funding is provided by the government of The Netherlands and the Swedish International Development Cooperation Agency).

Senator Mohamed Dukuly of Bomi County was suspended along with two finance officials of the Senate. They are the Senate's comptroller, Hector Frank and the Procurement Officer, Reginald Gerring. The Senate also requested the three men to submit themselves to an ad hoc committee for investigation.

Nimba County Senator George Koukou chairs the ad-hoc committee. It is to investigate financial transactions at the Senate for the past two years. Senator Koukou was also appointed to act as Ways, Means, Finance and Maritime Chairman.

The plenary decision followed the rejection of a motion for reconsideration filed by Senate's Majority leader, John Gray of Cape Mount. Senator Gray last Tuesday filed a notice for a motion of reconsideration. He filed the motion after the Senate decided on the suspension of the Ways, Means, Finance and Maritime Committee chairman.

TotalFina commissions ROV survey of Erika wreck
CSO International, a French unit of the Coflexip Stena Offshore Group (Nasdaq: CXIPY; French Reglement Mensuel: CFI FP), headquartered in Paris announced today that Totalfina has awarded it with a contract for a detailed surveyon the two portions of the wreck of the tanker Erika

The contract is part of ongoing operations undertaken during January 2000 by the Triton(R) XL 18, aboard the "Abeille Supporter", for the Maritime Prefecture of Brest. The Triton(R) XL 18 had patched leaks on the two portions of the wreck.

For this new investigative mission, Totalfina chose the dynamically positioned vessel CSO Marianos, one of the 15 vessels of the CSO Groupsubsea construction and installation fleet . The Marianos is a subsea intervention vessel for diving support able to work in all conditions, in any latitude, for construction works and saturation diving on offshore oil fields.

The CSO Marianos, which has been on site since February 5, will operate two Triton(R) XL work class, remotely operated vehicles (ROVs), the XL 18 and the XL 34, and a Tiger survey class ROV.

The Triton(R) XL is manufactured and distributed by Perry Tritech, an American company based in Florida and one of the world-leading manufacturers of subsea remotely operated vehicles. Perry Tritech is a 100% owned company of the Coflexip Stena Offshore Group.

Jean-Michel Dumay, Chief Executive Officer of Coflexip Stena Offshore International, commented: "This mission demonstrates the intervention capabilities of the Triton(R) XL as well as the CSO operational teams, whose performance during the investigation and repair work in January were exceptional given the very low visibility and difficult conditions on the site of the wreck."
