UK-based sail power technology company Windship Technology Ltd. on Tuesday (3 March) announced the outcome of wind tunnel tests conducted to validate results of an earlier computational fluid dynamics (CFD) test of the technology.
Industry experts, prospective clients in the shipping, commodities and petrochemical sectors together with UK government officials gathered at the Mitchell – Wolfson Unit Wind Tunnel at the University of Southampton to view the testing of the most recent Windship Technology model in February 2020.
The patented UK designed Windship rig system will materially help the shipping industry closer towards achieving its 50% reduction in emissions by 2050, as required by the IMO- which has recently acknowledged wind propulsion as one of the solutions for the shipping industry to meet decarbonisation targets, as outlined in the MEPC_C75_Inf26.
The solution, known as the Windship Auxiliary Sail Propulsion System (WASPS), uses fixed wing sail technology, whereby three 35-metre high masts installed on the deck of a vessel will each have three aerodynamic wings fitted (pictured) to exploit the power of the wind.
The system allows reductions in engine power to be made in order to achieve the same speed and so maximise fuel saving and emissions reductions, saving a minimum of 30% of the CO2 emissions annually.
The Windship system combined with reduced engine revolutions and other ship optimisation could save up to 80% of fuel and emissions. This aspirational approach will bring closer possibility of a Carbon Neutral ship well in advance of 2050.
“We are delighted with the results of the wind tunnel testing and they further illustrate how we will help the shipping industry to make a significant reduction in CO2 emissions,” says Simon Rogers, Technical Director.
“We are in discussions with potential development partners to build and install the prototype system.”

The COVID-19 pandemic continues to evolve and MPA is working closely with other agencies to monitor the situation, both globally and in Singapore, the port authority tells Manifold Times.
Caroline Yang, President of SSA, addresses issues earlier raised by players; including PMC No. 04, the seven-day restriction, contactless bunkering, sampling point, hose connection, and more.
IBIA Asia, ABIS, sources from Singapore’s bunkering and surveying companies, and an industry veteran share with Manifold Times the issues expected from MPA’s latest Covid-19 measures.
The top three positive movers in the 2020 bunker supplier list are Hong Lam Fuels Pte Ltd (+13); Chevron Singapore Pte Ltd (+12); and SK Energy International (+8), according to MPA list.
‘We will operate in the Singapore bunkering market from the Tokyo, with support from local staff at Sumitomo Corporation Singapore,’ source tells Manifold Times.
Changes include abolishing advance declaration of bunkers as dangerous cargo, reducing pilotage fees on vessels receiving bunkers, and a ‘whitelist’ system for bunker tankers.
