DNV gave AiP (Approval in Principle) for the three-wing rig created to offer wind power to big ocean-going ships. According to Windship Technology of the United Kingdom, the patented concept can generate enough power to sail 80,000 dwt ship on major long transoceanic routes.

Unique rig design was created by fine-tuning the wings utilizing computational fluid dynamics (CFD) and extensive wind tunnel testing. Each rig comprises a three-foil set that stands between 115 and 150 feet (35 and 45 meters) high based on the ship’s scale. According to the company’s analysis, the rigs yield the best power density of each and every current wind-powered solution because every wing possesses trailing edge flaps that enhance the motive force generated for a wide range of incident wind angles.

These wings would be installed on vessels with a steel cruciform base that provides the ship’s junction and also houses the rig’s lifting and lowering mechanism. The rigs may be lowered fore and aft or even over ship’s side as needed for unloading and loading operations to allow port access as well as bridge height clearance. The rigs are autonomously controlled and rotate to get the most out of the available wind energy when the ship is in motion.

The rigs are included in Windship Technology’s design as part of a complete zero-emission shipping system. The rigs are made of composite materials to save weight and have a diesel-electric drive with a comprehensive carbon capture system that minimizes fossil fuel usage while removing SOx, NOx, and particulate matter emissions and emitting zero CO2.

In reviewing the technology before giving the AiP, DNV used verified data and models depending on the long-standing and universally acknowledged criteria. Following DNV’s approval, Windship Technology’s CEO, Graham Harvey, stated that the firm is currently in a position to try the lots of discussions it has been able to have with charterers and owners who have all been looking for long-term alternatives.

“Fleet owners and charterers possess a zero-emissions alternative with Windship Technology’s whole-ship architecture, which is set to revamp the industry,” stated Simon Rogers, who works as the Technical Director at the Windship Technology. The maritime sector is racing against the clock as Energy Efficiency Existing Ship Index takes effect on January 1, 2023. We are pleased to get DNV’s Approval in Principle, with whom we have collaborated to achieve this classification.”
