Regular Engine Analysis

Can Reduce Maintenance

And Fuel Costs

Mesa, California-based MCA

Engineers, Inc., and German &

Milne, Vancouver, British Colum- bia, Canada, recently jointly con- ducted diesel engine diagnostic tests onboard containerships in

Long Beach and Oakland Harbors.

The diagnostic tests were con- ducted using the Computer Assisted

Machinery Analysis (CARMA) sys- tem. CARMA is a real-time analysis system that allows the operator to "see" inside the engine while it is operating, preferably between 60 and 80 percent of full load.

The four-stroke diesel engines tested were the drivers of 2,500-kw generator sets, developing 3,500 bhp. The data taken at the correct crank angle, and accumulated for analysis included: cylinder pres- sures at peak and injection; indi- cated mean effective pressure (IMEP); and the indicated horse- power of each cylinder at the cur- rent rpm and generator load.

The vibration and ultrasonic amplitudes can be measured in re- lationship to the crank angle at vari- ous locations and can indicate worn valves, springs, piston rings, exces- sive clearance in cylinder liners, wrist pin bearings, main or bottom end bearings and faults with the fuel systems including pump and injectors.

According to MCA Engineers,

Inc., the data is captured and dis- played in real time on the monitor screen and stored for later review.

Selected printouts can be made of the stored data on-site for a more detailed review. Using the data, engines can be precisely balanced.

Regular monitoring with engine analyzers allows one to predict fail- ures and detect most faults that plague reciprocating machinery. A major Gulf Coast company reports that replacement of components showing abnormal performance has reduced maintenance costs by 40 percent and additionally fuel costs have been reduced by 20 percent.

IMO Issues New Rules

For Tanker Design And

Oil Discharge Control

The Marine Environment Pro- tection Committee (MEPC) of the

International Maritime Organiza- tion (IMO) has adopted require- ments for the design of new oil tank- ers and revised arrangements for existing vessels in MARPOL Regu- lations 13F and 13G respectively.

The new regulations will become effective on July 6, 1993.

Reflecting the opinion of the In- ternational Association of Indepen- dent Tanker Owners (Intertanko) that owners should be able to choose from several designs which offer an equivalent level of environmental protection, Regulation 13F (new tankers) provides for either double- hull or mid-deck designs. For exist- ing ships, Regulation 13G states that these vessels should be subject to a stricter regime of surveys and inspections.

The MEPC session also modified

MARPOL provision Annex 1, Regu- lation 9 governing permissible rates of oily discharge from tankers. The instantaneous rate of oil content in discharge must now be no more than 30 liters per nautical mile.

An additional clause states that vessels delivered by July 6, 1993 must have oily water separating equipment for 15 ppm oil content.
