(LONDON) — The application of wind-assisted propulsion systems (WAPS) across a variety of vessel types is nearing a tipping point with deployment likely to increase rapidly, but the lack of standardization for verifying fuel savings and concerns about equipment availability must be addressed, says Lloyd’s Register’s new report on applying wind-assisted propulsion to ships.
With the industry close to achieving 100 installations and the order book reflecting the diversity of vessel types employing WAPS, along with increasingly substantial deployments as technologies move beyond prototype and pilot phases, the absence of a standard for verifying potential fuel savings is creating uncertainty for operators looking to select solutions.
With WAPS deployment likely to increase rapidly, driven by growing shipyard and operator familiarity with solutions, scaling up the supply chain to meet expected demand is a potential challenge. With several suppliers delivering very few units today – but with more suppliers set to enter the market in the near future – shipowners and operators will need confidence that WAPS suppliers can remain competitive and deliver increasing numbers of units without jeopardizing project time frames.
The report also points to the need for a wider base of shipyards with installation capabilities to meet expected demand, with only around 16 yards to date having carried out WAPS retrofits. While installations are not unfeasibly complex, they may be best implemented over multiple time periods, so project planning is a key consideration. Coordinating installations with scheduled maintenance and component lead times, while working out the best time to install, safeguard compliance and minimize carbon cost exposure can prove challenging, the report says.
“Wind-assisted propulsion systems are increasingly being used by ship operators to reduce fuel consumption, meet energy efficiency regulations and minimize exposure to carbon costs,” said Dr. Santiago Suarez de la Fuente, Lloyd’s Register’s ship performance manager. “With 29 installations between 2018-2023 and 72 in the order book, LR’s new research report demonstrates that there is growing confidence in the available solutions.”
“There is a perfect storm brewing when it comes to reducing (greenhouse gas) emissions in shipping,” said Gavin Allwright, secretary, International Windship Association. “New regulations, price challenges for existing and new fuels, along with the growing pressure from cargo owners to reduce scope three emissions. These are driving the deployment of wind propulsion technologies, both as wind-assist and primary wind, retrofit and newbuild, however these systems need to be robust, safe and validated in order to build trust in the market and lay the foundation for scaling these across the fleet.”
The report collates technology insights from LR and industry experts. It includes an in-depth analysis of the current market, cost and compliance drivers, regulatory issues and technical challenges.
