INCREASED PROFITS FOR GAS TURBINE CONTAINERSHIPS BY UNIQUE APPLICATIONS OF COMBUSTION TECHNOLOGY AND HYDRODYNAMICS
The nearly five-fold increase in the marine fuel price structure over the past four years has created an unparalleled challenge to maintain healthy profit margins in all ship operations. Seatrain Lines' gas turbine powered, high-speed containerships have been uniquely and boldly converted to lower operational fuel costs. Modifications to the Euroclass's schedules, driving propellers and to the fuel and combustion systems have been analyzed, tank or lab tested and put into full-scale service. This paper provides theoretical data reporting on the techniques that have permitted the world's first successful program to burn blends of heavy (residual) marine diesel oil in aircraft-derivative engines, along with analtycial data from radical asymmetric propeller studies, model tests and from the full-scale configuration. When combined, these applications of combustion technology and hydrodynamics have produced economies that have saved up to 30 percent of potential annual fuel costs. The rationale that led up to the selection of these modifications is included.
