Abstract

Efficient ship operation has always been a challenge of paramount importance to the ship owner, aiming to minimize operational expenditures and to maximize annual revenues. Nowadays, efficient ship operation is even more important due to the global warming phenomenon and the urgent need to reduce greenhouse gas emissions, next to the fuel cost. In the present chapter, we consider the possible retrofitting of two existing vessels, namely a bulk carrier and a container ship, on the basis of results of conducted hydrodynamic optimizations. For both vessels, bulbous bow and operational trim optimizations were carried out using advanced CFD tools. In addition, a weather routeing tool was developed and applied to the operation of both vessels, assuming realistic operational conditions and online weather data, while aiming at the reduction of fuel oil consumption.
