At 15:00 on January 30, 2026, ContiOceanEnvironment Tech Group Co.,Ltd.(“ ContiOcean”) proudly unveiled the ContiOceanPowerFoil suction sail system at the NK (Nippon Kaiji Kyokai) Quarterly Forumheld in Imabari, Japan，over 150 shipowners and shipyardrepresentatives from around the world jointly witnessed this historicbreakthrough. Simultaneously, the ContiOcean PowerFoil received the Approval inPrinciple (AIP) certificate from ClassNK, marking international authoritativerecognition of the innovative technology's safety, reliability, andenvironmental performance, and injecting strong momentum into the developmentof green shipping.
The ContiOcean PowerFoil is driven by adual-engine system combining Bernoulli's Principle with AI headingcollaborative control, constructing an all-condition, high-efficiency auxiliarypropulsion solution. Verified through wind tunnel testing and large-modelsimulation, the system enables vessels to achieve 15-30% fuel savings,delivering significant energy conservation and emission reduction results. Itscore innovation highlights include:
Active Suction Propulsion for EnhancedThrust
The sail incorporates a high-speed fan thatactively draws air through its porous surface, creating a stable pressuredifferential across the sail. This generates lift forces 6 to 7 times greaterthan rigid sails, significantly improving energy conversion efficiency.
Breaking Headwind Limitations forAll-Weather Operation
The ContiOcean PowerFoil substantiallyreduces the unusable wind angles encountered by conventional sails in headwindconditions, adapting to diverse wind scenarios and ensuring stable auxiliarypropulsion in all weather conditions.
AI Intelligent Management for OptimalEnergy Efficiency
Equipped with an AI-driven heading controlsystem, it collects real-time multidimensional data including wind speed,heading, and vessel attitude, accurately calculating optimal sail angles andsuction intensity to ensure the vessel maintains peak energy efficiencythroughout the entire voyage.
Dual Assurance: Safety, Compliance, andCommercial Value
In terms of safety and operations, thesystem features a hydraulic lifting mechanism enabling rapid sail deploymentand retraction, flexibly responding to port operations and severe weatherscenarios to ensure navigational safety. Its skid-mounted design significantlyreduces the number of moving parts, effectively lowering maintenance costs andfailure rates while improving operational efficiency.
Regarding compliance and authoritativeendorsement, ClassNK stands as one of the world's most stringent maritimesafety certification bodies. Its AIP certification represents high recognitionof the ContiOcean PowerFoil's technical feasibility and safety reliability.This milestone signifies the product's successful transition from conceptualdesign to engineering implementation, allowing it to be directly incorporatedinto compliance schemes for newbuildings or existing vessel retrofits, helpingshipowners mitigate regulatory risks.
Deepening Innovation: Empowering GreenShipping, Embracing a Decarbonized Future
The simultaneous achievement of theJapanese debut and ClassNK AIP certification marks a significant breakthroughfor ContiOcean Group in the field of green shipping technology. Moving forward,ContiOcean will continue to deepen its commitment to green shipping innovation,continuously iterating technologies and optimizing solutions to assist globalshipowners in efficiently achieving energy conservation and emission reductiongoals, driving the shipping industry toward a smarter, greener, and more sustainablefuture.
