As part of INSW\u2019s long-term sustainability strategy, the partners set out to explore how much extra savings and emission reductions ship design, in conjunction with Norsepower Rotor Sails\u2122 could provide to the concept. <\/strong><\/p>\n

When applied to newbuild vessels that are optimised for wind propulsion use, the results have so far been excellent, and this was no exception. The outcome is a resounding confirmation of the technology\u2019s potential with total savings of up to 876 kW of propulsion power on one representative INSW MR tanker route from San Francisco to South Korea \u2013 equating to around 597.2 MT of fuel per annum, and the additional fuel savings attributable to the design contributing up to 13.5% of those savings in certain conditions.<\/p>\n

NYSE-listed INSW embarked on the project with a clear goal: to assess whether wind propulsion could deliver meaningful benefits for the tankers of the future. \u201cWe focused on more than just energy savings and emissions reduction \u2014 our goal was a concept design that works in the real-world conditions of the MR trade.\u201d explained Michael LaGrassa, Director of Performance and New Construction at INSW. \u201cThat meant ensuring reasonable build costs, equivalent cargo capacity, and a design fit for purpose. Our approach was to test a wide range of scenarios across the MR trade, rather than rely on selectively favorable assumptions.\u201c<\/p>\n

With Norsepower Rotor Sails at its core, Bluetech\u2019s design modifications were demonstrated to extract signifanctly greater forward thrust. In one of the simulations, on a San Francisco\u2013South Korea route, two 35m x 5m Norsepower Rotor Sails delivered an average propulsion power of 876 kW \u2014 equivalent to 597.2 MT of fuel annually. Bluetech\u2019s Director of Energy Savings Solutions, Sam Robin, emphasised: \u201cWe set out to develop a ship that is entirely WASP-optimised while maintaining every essential operational feature and meeting trade-specific restrictions. The result is a vessel design that significantly enhances propulsion without compromising practicality.\u201d<\/p>\n

The SeaWasp project also investigated performance across less favourable wind conditions. On the South Korea\u2013Singapore route, for example, savings of 185.9 MT of fuel were still achievable. This balanced approach was important to ensure the commercial projections of the project remained realistic.<\/p>\n

Bluetech\u2019s naval architects incorporated a range of innovations to maximise efficiency. \u201cThe BT50 design is itself approximately 12% more efficient than the typical tanker performance profiles in the sample fleet. Our design modifications enhance that efficiency even further,\u201d said Robin.<\/p>\n

Above the waterline, the design includes an aero superstructure and semi-enclosed mooring stations to reduce wind disturbance. Beneath the waterline, a new fin system dubbed \u2018blueSURF\u2019 was shown by CFD analysis to significantly increase power saving potential. Juha Hanhinen, Bluetech\u2019s Head of Hydrodynamics, admitted: \u201cWe were surprised by how significant the fin effect was \u2014 it creates a powerful case for combining hydrodynamic improvements with wind propulsion.\u201d<\/p>\n

Norsepower also supported comparative studies of different Norsepower Rotor Sail\u2122 configurations. \u201cIn the simulations related to this specific case, four 24m x 4m sails were marginally better, but overall, the two 35m x 5m sails offered the highest potential savings at lower cost,\u201d explained Severi Sarsila, Sales Engineer at Norsepower.<\/p>\n

The collaboration has highlighted how carefully optimised vessel design, paired with proven wind-assisted propulsion, can unlock new levels of efficiency. As Bluetech\u2019s Robin concluded: \u201cThe SeaWasp concept shows that wind propulsion is not just an add-on \u2014 it can be central to the way ships of the future are designed.\u201d<\/p>\n

Ville Paakkari, Head of R&D at Norsepower, added: \u201cSeaWasp is an inspiring example of how naval architecture and advanced wind propulsion can be combined to unlock the full potential of our technology. By optimising the design around the Norsepower Rotor Sail\u2122, Bluetech and INSW have shown how newbuild projects can deliver both impressive fuel savings and practical fleet operations. Going forward, we will be able to show even bigger savings and emission reductions with the Norsepower Sentient Control, our data-driven control system\u201d<\/p>\n

William Nugent, Chief Technical and Sustainability Officer at INSW added: \u201cThe future certainly looks brighter for our next generation of tanker shipping. Creative problem solving following a thorough design process will be one of the keys to success.\u201d<\/p>\n
