Performance Analysis Report (PAR)
To verify the condition of the propulsion system, Caterpillar has developed the Performance Analysis Report (PAR) for marine engines.A PAR is an in-vessel test procedure that is performed by a Caterpillar analyst under operating conditions. The test compares the performance of all marine engine systems to the original testing specifications.When a PAR is conducted at Sea Trial, an installation of high quality can be ensured. The PAR will confirm the matching of the following components for optimum performance and for fuel efficiency: hull, rudders, propeller, marine transmission, ventilation and cooling systems.Caterpillar recommends scheduling a PAR in order to maintain optimum performance.A periodic PAR can define deterioration of the propulsion system. A PAR can assist in repairs, in overhauls, and in maintenance schedules. This will help to provide the most economical, efficient cost of operation.
