Installation of Unloading Arms for Kochi LNG Project

Successfully installed critical LNG unloading arms despite challenging seabed conditions at Kochi LNG terminal.

Installation of Unloading Arms for Kochi LNG Project

Unloading arms (ULAs) is the most important and critical unit equipped in the LNG receiving terminal, requiring a high stability standard for its installation to avoid any potential damage or leakage during the unloading of LNG from ship. Usually these ULA’s are installed placing cranes on the jack-up barge. However, the sub-soil under seabed at Cochin LNG site could not hold the jack-up barge. At this stage, LOTS-India gave a solution for fixing the ULAs from a spudded tidal barge with 300-ton crane mounted on it. The novel and unique proposal was accepted both by EPC Contractors – CINDA Engg. & Construction Private Limited &Petronet LNG. LOTS-India and its associate Company – Master Shipyard Private Limited pioneered the spudded platform specific for this project requiring complex design, engineering, fabrication, erection on a 4000-ton dumb barge by fixing 8 spuds. The 4 ULAs were finally installed in place successfully on 15th November 2011.
