[1] The float-on/float-off capability of the Donghai class is achieved via its semi-submersible hull design. [1] This ship has received NATO reporting name Modified Hansa Sonderberg class, [2] [3] [4] because it is derived from the Hans Sonderberg-class anchor handling tug supply vessel designed specifically for heavy-lifting and transporting large and heavy equipment such as oil rigs, and Donghai Island performs similar functions.
