Russia and the Black Sea, which will be analyzed and presented during the two leading Shipping Exhibitions in these areas throughout the next 18 months.

Regarding Russia, St. Petersburg leads the expansion with more than 160 ves- sels scheduled to port this year. The local market also plans to grow exten- sively while also planning the eventual introduction of turnaround and home port operations. These developments will be instrumental in the formation of the exhibition, conference and seminar programs at the fifth NEVA maritime exhibition at St. Petersburg from Sep- tember 25-28, 2001.

Meanwhile, Dolphin Exhibitions will present Dolphin Capital Cruise for the

Black Sea at its fourth international maritime show Odessa 2000 in the

Ukraine, which will occur from October 17-20, 2000.

Mackay Attains Raytheon's

Field Service

Mackay Communications has acquired Raytheon Marine Company's seven U.S. field service locations. The addition, which includes four Raytheon locations on the East Coast and three on the West, expands Mackay's presence into all major U.S. ports. The new locales will be run as part of Mackay

Marine.

Marquette Expands Fleet

Marquette Transportation, Paducah,

Ky., has added a pair of 8,000-hp vessels to its inland waterways towing opera- tion. Currently being built at Quality

Shipyard in Houma, La., the 180 ft. (54.9 m) sisterships of John Paul Eck- stein were designed by CT Marine,

Rowayton, Conn. Named Kay A. Eck- stein and Ray A. Eckstein, the vessels will commence operation this month, and in August, respectively.

Powered by twin CAT 3612 marine engines, each rated at 4,000-bhp at 900- rpm, driving Bollinger propellers, the new vessels' propulsion package will be identical to John Paul Eckstein, except

Appeal Favors Comsat

Under the terms of the contract with a maximum value of $111.9 million over a five-year period, the U.S. Court of

Appeals for the Federal Circuit reversed and vacated a ruling by the U.S. Court of Federal Claims, thereby validating this contract awarded by the U.S. Navy to Comsat. The court of claims decision had effectively blocked implementation of the company's contract beyond Janu- ary 2001 to provide worldwide satellite services to the Navy via the Inmarsat satellite system. Litigation began when

Stratos LLC challenged the award of the

Navy contract to Comsat in a federal court of claims. Originally awarded to

Comsat in June 1999, the contract is an

Willard Marine, MetalCraft

Sign Teaming Agreement

Fiberglass marine defense contractor,

Willard Marine, agreed with Canadian aluminum boat manufacturer Metal-

Craft Marine to provide Willard with an extensive line of aluminum boat designs adding to its already successful fiber- glass line of small boats and RIBs. Met- alCraft, who is a major supplier to the

Canadian Federal Government, will rep- resent Willard's line in Canada.

Lubricant Technology Proven Tough Under Fire (Continued from page 43) engine with 4 percent HFO contami- nation before and after the use of Taro 40 XL 40.

Undercrown deposits

Due to the continuous increase in output, the piston cooling space tem- peratures have been increasing. The piston undercrown temperature is typ- ically about 250°C. In the latest engines, temperatures of 300°C have been measured. This can cause carbon deposits on the piston undercrown due to thermal carbonisation of the lubri- cant. The carbon deposit layer forms an insulating layer upsetting the piston cooling increasing the piston tempera- ture. Temperature increases of around 100°C have been measured.

A second deposit formation mecha- nism is the adhering of the asphalt par- ticles that originate from HFO conta- mination. The build up of such a car- bon layer in the piston coolant cham- ber is illustrated in Figure 5.

To cope with the extreme tempera- ture conditions, especially in highly loaded engines, the thermal stability and oxidation stability of lubricant had to be substantially increased. FAMM has found that the thermal stability and oxidation stability of Taro 40 XL 40 has matched and even exceeded a number of synthetic commercial oils.

Figure 6 shows a similar piston cool- ing space of an engine lubricated with

Taro 40 XL 40. No carbon was formed in spite of very high cooling space temperature (300°C) and HFO conta- mination of 4 percent. This was due to a combination of thermal stability and asphaltene dispersion technology.

Piston Head Corrosion

Undercrown deposits in combina- tion with high load operations can lead to piston head corrosion. Undercrown piston deposits inhibit cooling, result- ing, as already mentioned, in an increase of about 100°C in piston tem- peratures. Above 450°C, some sodi- um/vanadium salts form a melt with the piston crown material, causing hot corrosion on top of the piston. In case of high load operations and reduced piston cooling, the critical temperature is easily reached at the top of the pis- ton. As a result, material melt and material removal by hot corrosion is occurring. This means earlier replace- ment of the piston crowns and, in severe cases, hole formation in the pis- tons, a problem which could endanger the safety of a ship.

Field inspections of a number engines lubricated with Taro 40 XL 40 indicate that in nearly all cases the pis- ton undercrown deposit problems were eliminated. Very severe applica- tions, such as power plants in the trop- ics running constantly at 100 percent load, were included in the study.

Looking back at the experience of the last three years, Roger Stubbs,

FAMM's General Manager Lubricants

Europe, sees Taro's success as further evidence that marine lubricants cannot be regarded as just another commodi- ty. He said the lubricant had shown 'outstanding' levels of cylinder and crankcase protection at a time when high output engines with high internal temperatures and pressures and reduced oil consumption had become the norm.
