The shipping industry faces growing pressure to decarbonise and the use of wind assist technology has been hailed by some as the answer, but there remains a great deal of uncertainty over the true performance expected.

It can be claimed that wind assist technologies might provide significant proportions of the total propulsive power demand for a given vessel. However they may only do this in ideal environmental and operational conditions and this scenario may never actually be realised during the lifecycle of the ship

To understand the value in this technology we must first understand how to assess it. This paper identifies some of the issues involved. The sensitivity of technology sizing, operational area, voyage modelling and environmental conditions are all considered. The performance is modelled using WASPP: a performance prediction tool for wind assisted ships, and the results examined using a case study vessel and VLM: a voyage level modelling tool.
