| Abstract: |
| The 45000t Con-Ro ship is specially designed without lashing and hatch cover, but there is an ultra-high guide frame in a maximum length of 30m to keep the position of containers. In order to make the ultra-high guide frame installed precisely and in compliance with the rules and regulations, the traditional installation technique and precision control are compared and analyzed according to the special structure and function of the ultra-high guide frame, and new installation procedures are proposed to enhance the precision control at different stages. This paper introduces the structure characteristics of ultra-high guide frame for the type of ship, elaborates the difficulties and the precision planning of the installation, explains the pre-assembly technique of the block, and describes in detail the key points of precision control at different stages of the installation. The procedures are validated feasible in the container lifting test and the result shows that the proposed method can effectively guarantee the construction precision of the ultra-high guide frame without losing production efficiency. The study could provide reference for the subsequent products which need to improve construction quality and efficiency. |
