Simulation and Erection Scheme for Large Section of a Ship without Ground Support
The main hull of one 1600-ton wind power engineering ship with deep submersible bottoming multi-functions is 56 m high(137 m on the top of the crane).The main hull is divided into upper and lower layers,the tween part is supported by floating box column and truss of about 40 meters high,and the superstructure needs integral hoisting for erection.The weight of the large section is more than 200 t,and the erection needs to be implemented at an altitude of more than 40 meters,involving above 3 000 meters erection welding,the section of which objectively needs to be hoisted for assembly without ground support and with no margin.Therefore,it is of practical significance to carry out construction method research and ergonomic improvement research for this type of general section erection.
