The recent availability of regular parametric data on ship’s machinery and behaviour has opened up new possibilities to develop and apply active mathematical models of ship propulsion systems.
The BMT-led VTAS project has combined large publically-available metocean datasets with onboard ship performance data to build the best possible models for specific vessels and the seagoing conditions experienced. These models enable the fuel-saving benefit of energy saving technologies (EST) to be assessed and thus support a business case for their introduction.
This lecture presents the potential benefits of hydro-dynamic, wind and thermal based technologies for a 61,000 dwt ship. An assessment of the benefits of wind-based technologies such as Flettner rotors, Wingsails and Turbosails is presented alongside those for an Organic Rankine Cycle-based technology.
These studies provide the foundation for supporting a wider assessment of feasibility and economic viability of an EST installation. Adoption of EST would support the IMO’s target to reduce the carbon intensity of international shipping by at least 40% by 2030.
