Structure planning of 13470 DWT capacity jetty on Liquid Berth II Caspian Sea, Turkmenistan

Abstract

Liquified Natural Gas is one of the products produced from refineries in the Caspian Sea. LNG production increases due to demand, causing the addition of new offshore platforms. To provide loading and unloading services for LNG, a special dock is needed, for this reason a special liquid bulk jetty with a capacity of 13470 DWT is planned. Structural planning using STAADPRO V8i Select Series 6 software, using British standards in planning. The jetty structure is expected to be strong against the loads that work due to environmental conditions and ship impacts. Structural analysis is carried out by comparing the structure’s Unity Check Ratio value with the Unity Check Ratio permitted based on applicable standards. The result is that the structure is able to withstand the working load with details of 4 Breasting Dolphin structures, 2 Mooring Dolphin structures, 1 Jetty Head Platform structure, and 1 Trestle structure.
