World’s largest specialty valves

Hydrocarbon Engineering,


McDermott has achieved a first of a kind in the valve industry; creating the world’s largest forged body specialty valve, in collaboration with a leading valve manufacturer. The valves are destined for the INPEX operated Ichthys LNG project.

Each valve measures approximately 9 m in length and 7 m in height, and weighs more than 100 t. The first valve has been successfully tried and tested. The second valve is currently undergoing factory acceptance testing and is expected to be ready shortly. Once all six valves have passed factory testing, two will be installed offshore in 270 m of water, while the remaining four will be installed onshore, one at the landfall block valve and three at the processing facility at Bladin Point.

Jonathan Parkes, McDermott Senior Project Director, commented: “The Ichthys Project umbilical, riser and flowline infrastructure – which will be installed at the Ichthys Field offshore Western Australia – requires connection of the subsea riser base to the 42 in. gas export pipeline going to the onshore LNG processing facility. This meant that six 42 in. valves had to be specially designed and fabricated to meet the 40 year design criteria. To our knowledge, these are the world’s largest, single piece forced, top entry ball valves”.

Tony Duncan, Executive Vice President, Subsea, said: “This is a great demonstration of client demand driving innovation, and through collaboration, team work and effective supply chain management, on a global scale, we have created a first in the industry”.
