WiSP 2

WIND-ASSISTED SHIP PROPULSION

Initiative

WiSP 2 will focus on making evaluations within EEDI and EEXI and from real operational conditions. The aim is to prove what kind of fuel savings shipowners can achieve, enabling them to make informed investment decisions, whilst also keeping the upcoming CII requirements in mind.

Background

In recent years, there has been a resurgence of research on wind-assisted ship propulsion. The slow uptake of wind propulsion is partially due to marginal profitability and finance options with the present low oil prices and the poor market. However, a recent study by CE Delft [1] on the market potential for wind propulsion found that another major barrier is the shortage of transparent and independently verified information and methods to predict the performance of wind propulsors. Other barriers identified are lack of sufficient practical examples and tailor-made work to demonstrate compliance with statutory and class rules and regulations.

Objectives

  • Improve methods for transparent performance prediction;
  • Use the improved methods to provide ship owners/operators with fast low-cost predictions for their fleet;
  • Further review of the regulatory perspective, recommend improvements and clarifications, and provide examples to establish compliance;
  • Development of basic performance prediction tool, to be used by participants '
  • Proposal for (in-service) speed trials with wind assist;
  • Assess the influence of manoeuvring compliance and seakeeping operability on performance.

organisation

WiSP 2 is initiated by MARIN, in cooperation with American Bureau of Shipping (ABS) and together with a large number of participants, to investigate ways to overcome barriers to wind propulsion uptake. To this end, we are pleased to present the research activities as outlined in the leaflet. The detailed research proposal is under development with current WiSP participants and potential WiSP 2 participants to reflect their research interests and expertise. This proposal will be further adapted when new
participants join and additional research funds become available.
The aim is to cover the majority of marketed wind-assisted ship propulsors in this precompetitive project, thereby extending systems considered in the previous WiSP. The
project will not go into the details of company-specific design solutions.
