New MWH Valve Rotators

In LNG Ship

Prove Cost Effective

A field test to determine the abil- ity of Markisches Werk Halver's (MWH) valve rotators to correct ex- haust valve wear problems was re- cently performed on the LPG car- rier, MTV Sunny Lady, owned by

Olaf Pedersen's Rederi of Norway.

Studies revealed that the aver- age life for a seat coated exhaust valve was about 2,552 hours.

Turnomat valve rotators reportedly increase the time between engine overhauls and also allow even dis- tribution of heat on the seat area therefore reducing peak tempera- tures, thermal stress and corrosion sensitivity.

The MWH valve rotators were first installed in 1989 and the first inspection conducted a year later revealed that only two of the 12 standard exhaust valves reached 4,400 running hours and all 12

Nimonic valves were still in excel- lent condition and could be refitted.

The final results of the test showed that in comparison to the original valve/rotator combination used be- fore the test, the lifetime of the valves fitted with the combination of 12

Nimonic and 12 Turnomat valve ro- tators extended the lifetime of the exhaust valves from 31 percent to 130 percent. Even after 7,200 hours the Turnomat showed no noticeable signs of wear.

As a result of the tests, the

Pedersen shipping company has in- stalled Nimonic valves with

Turnomats on all of its ship's en- gine cylinders.

Strong Charter

Market Ensures Future

Of Older Boxships

According to a report on the liner markets by Clarkson Research

Studies, U.K., a strong charter market will allow older container vessels being displaced from the main east-west trade by a new gen- eration of ships to be reemployed in the north-south trade or in feeder services, rather than sold for scrap.

Clarkson's review of world ship- ping trends indicates that there was a strong demand for containerships during the last half of 1991. A 1,200 twenty-foot equivalent unit (TEU) containership on a year-long char- ter was going for $13,000 a day at the end of 1991, as opposed to a rate of $12,000 a day last summer.

A shortage of world tonnage and the rising price of new box ship construction will continue to main- tain solid charter rates, despite a weak start in early 1992 and a present slump in international freight rates, reported Clarkson.

This should ensure that both new and older containerships will be absorbed by the market.

The company reported that the rising world demand for tanker and dry bulk shipbuilding berths has almost doubled the cost of new large cellular container vessels, now be- ing quoted by Far East yards at $63 million for a 2,500 TEU ship.
