Nowadays, a variety of technical solutions to improve energy efficiency and reduce emissions is available to the shipping industry, offering a wide range of possible solutions to ship builders and operators. However, the selection of the best performing option is subject to the individual specifications of the vessel, its trade route, lifetime expectancy and many other factors. Furthermore, the decision-making process usually accounts for multiple objectives, such as energy efficiency, environmental impact, reliability and safety, which in various cases may be conflicting. This chapter demonstrates how Model Based Systems Engineering methods and associated tools can support the assessment and quantification of ship machinery system performance at concept design and in retrofit applications, aiding decision makers. Two typical application cases of the HOLISHIP project are presented: the energy efficiency and reliability assessment of a hybrid Offshore Supply Vessel; and the retrofitting of a bulk carrier with a fuel recovery from a sludge unit. |
