The American Bureau of Shipping (ABS) and the Maritime Research Institute Netherlands (MARIN) have launched the second phase of the Wind assisted Ship Propulsion joint industry project (JIP) to promote the use of wind propulsion.
In the second phase, known as WiSP 2, the project will make assessments from real operational conditions as well as within both the energy efficiency design index (EEDI) and energy efficiency existing ship index (EEXI).
MARIN transport and shipping team leader Patrick Hooijmans said: “This Wind assisted Ship Propulsion JIP picks up where the successful phase I project left off, with a wider scope and fed by additional insights gained from our earlier phase of analysis.”
The objective of the project is to provide shipowners with proof of the fuel savings they can expect while also meeting the upcoming carbon intensity indicator (CII) requirements, therefore allowing them to make more informed investment decisions.
The project will also focus on compliance with regulations, specifically regarding manoeuvring.
The project’s second phase will involve the development of a basic performance prediction tool, proposal for (in-service) speed trials with wind-assist technologies and application of new methods in cases, such as a validation case, over the course of two years.
The scope will also cover enhancement procedures for transparent performance prediction.
Compared to the earlier phase, the considered wind propulsors and propulsion line types will be extended in this phase.
In addition, the project will include regulatory perspective review, improvement recommendations, clarifications and evaluation of the impact of manoeuvring compliance.
ABS Copenhagen global sustainability centre director and co-initiator Jan Otto de Kat said: “These new findings from WiSP2 will be condensed in updated recommended methods for performance prediction and reported as submissions to Marine Environment Protection Committee (MEPC) and potentially other committees in International Maritime Organisation (IMO).”
This joint industry project was launched in Paris in May 2019.
