Canada-based Teekay Corporation has renewed its contract with Propulsion Dynamics for its hull and propeller performance monitoring system »Casper« Service. The Computerized Analysis of Ship PERfor-mance from Propulsion Dynamics is a turnkey subscription service that provides shipowners with decision support for technical and operational fuel efficiency programs. The two-year extension will cover 23 LNG carriers under the Teekay banner with a further seven ships to be included in the program as they are taken into Teekay management. As part of the Casper Service, the technical performance of individual vessels is used to evaluate realistic charter rates, review development of hull and propeller resistance, and determine economically optimal intervals for hull cleaning and propeller polishing. Comparisons between ships enable different hull coatings to be evaluated for fouling, and the effect on speed and fuel consumption. With Casper, the vessel's hull and propeller performance is regularly monitored and any anomaly is highlighted for corrective action.
