A printout of one cylinder data with an overlay from an adjacent cylinder. Such comparisons can isolate
problems and permit balancing the engine. Detection of cracked heads, clogged or malfunctioning
injectors, worn bearings and damaged valves is simple with the CARMA system.
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.
