Abstract : This report presents the results of emissions testing conducted on board the M/V KINGS POINTER in May 1995. The objective of this testing was to conduct baseline instrumentation, monitoring, and evaluation of the engine exhaust emissions as part of joint U.S. Coast Guard/Maritime Administration cooperative research on controlling air pollution from ships. The U.S. Coast Guard's interest in emissions testing arises from both its desire to meet all federal and state air quality regulations and the fact that in the future it may be called upon to enforce regulations in the marine environment. The U.S. Maritime Administration's interest in this and related research is based on its efforts to assure that its vessels and those of the privately-owned U.S. Flag Merchant Marine can comply with future air pollution control requirements. Underway tests were conducted of the 224-foot M/V KINGS POINTER in which two of its four diesel-electric generators were sampled for NO, NO2, CO, and SO2 in the exhaust. Additional data on fuel flow and power output were collected at five speeds over the full range of vessel operating ranges. NOx values were calculated and compared with standards proposed by the Environmental Protection Agency (EPA) and the International Maritime Organization (IMO). Results showed that average NOx values were 9.4 g/kWh which is slightly below the 10.9 g/kWh upper limit or cap that is being proposed by the IMO for a diesel engine with a rated speed of 1200 RPM. Additional conclusions and recommendations on the technique of portable emissions monitoring instrumentation are made. p4
