At about 10 pm on 2 August 2023, the sixth super typhoon Khanun made a strong landfall in Shengsi, setting off violent winds on the whole island, with the maximum wave height of 6 meters. However, under this severe weather, Drakoo wave energy generator developed by Hann-Ocean Energy demonstrated its strong wind resistance and stood tenaciously at the Fisherman's Wharf in Wulong Township, successfully passing the severe typhoon test.

Recently, Mr. Han Lei, General Manager of Hann-Ocean Energy (Zhoushan) Co., Ltd., was interviewed by Zhoushan Daily and introduced Drakoo wave energy generation technology and its development prospects, etc.

Hann-Ocean Energy’s Drakoo wave energy generator has been undergoing sea trials for nearly 11 months in Shengsi archipelago. The generator is now under the second round of sea trial after being modified technically and has so far achieved several impressive results.

On May 21, 2023, the "2023 East Cliff Forum-Innovative Development of Marine New Energy in Shengsi County" was successfully held in Sijiao Island, hosted by the People's Government of Shengsi County and organized by the Economic and Information Bureau of Shengsi County and Hann-Ocean Energy (Zhoushan) Co., Ltd.

On 5 May 2023, Hann-Ocean Technology successfully signed a contract with PanAust from Australia to design and build 17 units of RigiFloat containerized modular pontoons to be assembled into a modular ro-ro ferry for the transportation of mining equipment and vehicles.

On February 21, 2023, an exciting news came from Shengsi archipelago, that Hann-Ocean Energy's third-generation wave energy generator Drakoo had been successfully launched, officially starting the second round of six-month sea trial.
