DNV joins International Wind Ship Association

2022-11-16 10:42

 

According to the latest news: the DNV has recently joined the International Windship Association (IWSA) to further support and accelerate the adoption of wind-assisted propulsion systems in the global shipping fleet.

 

The use of wind-assisted propulsion systems by merchant ships has increased dramatically in recent years. It is reported that 21 large merchant ships equipped with wind-assisted propulsion systems are currently in operation, and it is expected that in the next 12 months, that figure is set to double. As the price of fossil fuels rises, the technology will become more cost-effective. So the growing membership of IWSA, a non-profit group that promotes the adoption of wind propulsion in global commercial shipping, reflects this trend. And, according to DNV, the IWSA is a key convener of key players in the field of sail-powered ships and has made significant progress in promoting the adoption of wind acceleration. After becoming a full member of the IWSA, the DNV will provide a new classification symbol for ships using wind-assisted propulsion systems (WAPS) . To date, DNV has issued in-principle approvals for many WAPS on the market and provides custom consulting services to guide customers in assessing the security and suitability of WAPS and which systems are suitable for their business.

In addition, DNV has issued an updated wind-assisted propulsion system technical standard ST-0511, the main update of which is the introduction of a new method to assess the fatigue strength of wind-assisted propulsion systems, and the performance of the system under extreme conditions.

 

ST-0511 technical standard is a complement to the DNV wind-assisted propulsion system classification symbol, focusing on the integration of ship systems, including new shipbuilding and refitting ships. The ST-0511 standard provides a framework for the verification and certification of wind-assisted propulsion systems, which can be used to obtain approval of principles, design or type, which can be obtained separately, also available as part of integration into the ship.

 

In addition to the fleet of large merchant ships equipped with wind propulsion technology, there are currently 10 small cruise ships using traditional soft sail technology with a total registered tonnage (GRT) of 50,000 tons. 

 

Of course, there is also a growing number of small ships (less than 400 gross tonnage) using wind propulsion technology, and the number of small ship retrofits is likely to grow further next year.

 

In addition, according to Gavin Allwright, secretary general of the IWSA, "Wind propulsion technology has been shown to reduce fuel use and associated emissions by 5-20 per cent when used as a wind assist. The energy-saving potential is even higher for ships that use primary wind technology to achieve higher levels of wind-powered propulsion energy. This makes wind energy a valuable way to reduce emissions from international shipping, both now and in the long term, and offers the potential to significantly reduce the overall carbon intensity of shipping, at present, the marine auxiliary propulsion system, especially the sailing industry, has become the preferred choice for energy saving and emission reduction in the navigation industry.

 

Dealfeng new energy technology (Tianjin) Co. , Ltd. , has long been committed to the development of drum sail system and other energy-saving emission reduction technologies. Stack wind is also a member of IWSA, an international organization that promotes and helps promote the adoption of wind propulsion programs in the commercial shipping industry worldwide. We welcome another classification society to join the IWSA family. At present, wind stack new energy has completed its own design and development for 10 × 2 meters under 10,000 tons and for 24 × 4 meters installed on ships above 10,000 tons, the two kinds of spinneret sail have finished the prototype manufacture and the roadbed experiment, and have also signed the order of the real ship. The company also has 20 to 24 meters wind-assisted propulsion of wind power operations, maintenance ships, transport ships, the whole ship design and manufacturing capacity, the ship has good mobility and comfort in navigation, at the same time can maintain a lower energy consumption, is an excellent energy-saving performance of the ship.
