Optimization of Rubber Fender of LNG Terminal

Optimization of Rubber Fender of LNG Terminal

LNG terminal could berth conventional membrane-type Moss LNG carriers with tank capacity of more than 16 times; 104 m3 ，but could not berth Moss LNG carriers with tank capacity of less than 16 × 104 m3 under extreme conditions． The reasons were analyzed． By comparing the design parameters of jetty rubber fenders at different LNG terminals，the optimization research of rubber fenders was carried out， and the optimization scheme of rubber fenders was put forward． The OPTMIOOR software was used to analyze the mooring before and after fender optimization，and the applicability of the optimization scheme was theoretically verified． After the optimization of the jetty fender，Zhoushan terminal safely berthed and unloaded 6 carriers with tank capacity of less than 16 times; 104 m3 ， which verified the applicability of the fender optimization scheme in practice．

The design unit has reviewed the hydraulic structure of the pier in accordance with Option 3, and the results show that the structural design can meet the modified force requirements. The results show that the structural design can meet the force requirements after modification. The mooring analysis was carried out for the Moss vessel type data provided by Osaka gas and "K" Line. The mooring analysis was carried out and the final decision was made to implement the rubber fenders according to Option 3. The rubber fender was optimized according to Option 3, and the vertical two drums and one plate of the inner fender was changed to a horizontal two drums and one plate. After the optimization, the height of the inner fender is 4.5 m, which is higher than that of the inner fender. After optimization, the height of inner fender is 4.5 m, which is 1.5 m higher than the original 3.0 m. The distance between the inner fenders was reduced from 74 m to 71 m, and the fender area was increased from 17.92 m2 to 22.4 m2. increased to 22.4 m2. The fender area was increased from 17.92 m2 to 22.4 m2. The fender area was increased from 17.92 m2 to 22.4 m2. The mooring compatibility between Moss vessel type and Zhoushan receiving station is greatly improved without affecting the matching of film vessel. The mooring compatibility of Moss vessel and Zhoushan receiving station was greatly improved without affecting the compatibility of the film vessel.
