BV to class large container ships built in China

The 16,000-TEU vessels will be the largest container ships built in China to date. One will be built at the Shanghai Waigaoqiao Shipbuilding (SWS) yard, and the other two at Shanghai Jiangnan Changxing Heavy Industry, part of which came under the management of SWS this year.
The design was developed by the Marine Design and Research Institute of China (MARIC) in cooperation with BV, which performed the drawing approval and conducted a thorough structural examination.
The vessels will have an overall length of 399m, a beam of 54m, and a draught of 16m. They will be able to operate at a maximum speed of over 23 knots with a single-screw propeller directly coupled to a 69 MW, two-stroke electronic engine.
According to the classification society, special consideration has been given to hydroelastic design (whipping and springing) issues. A hydroelastic examination was performed using BV’s Homer software in order to take into account extreme whipping loads due to slamming and additional fatigue damage due to springing, factoring in the elastic structural response of the ship.
The vessels will be granted BV’s VeriSTAR HULL DFL 25-year notation, which certifies various structural details, including hatch corners and coamings, for 25 years of fatigue life, following a spectral fatigue analysis with a 3D finite element analysis model. Furthermore, they will receive the class notations CLEANSHIP and FORS.
