McDermott completes EPCI contract in India
McDermott International has successfully completed installation works as part of an engineering, procurement, construction and installation (EPCI) contract for subsea infrastructure in India.
McDermott completed the engineering, supply and installation works with consortium partner, Larsen & Toubro subsidiary, LTHE for the S1 and Vashishta fields, which are approximately 26 km and 35 km from Indian coastal town Amalapuram, respectively.
The consortium completed pipeline end terminations, inline tee structures, a pipeline end manifold structure, rigid jumpers and approximately 50 km of umbilicals on the 93 km, 14 inch (356 mm) diameter dual pipeline, which extends from the shallow shore line to a maximum water depth of 700 m.
During the installation, McDermott had to overcome a number of challenges, including a four-month per year time restriction imposed by monsoon season.
“Engineering design for the Vashishta project was no easy feat due to the iterative nature of the design process which had to reconcile many factors such as soil conditions, jumper/spool loads, connector capacities, in-place environmental loads, pipeline expansion loads, installation weather limitations, vessel envelope constraints and mission equipment constraints,” McDermott Vashishta Project Director Ben Delves said.
The fields’ gas resources are being developed by India’s multinational oil and gas company Oil and Natural Gas Corporation Ltd (ONGC), and has now achieved first gas.
The Vashishta field estimated produce 9.56 billion m3 over 9 years and the S1 field expected to deliver 6.22 billion m3 over 8 years.
“I’d like to take this opportunity to congratulate ONGC in achieving this important first gas milestone,” McDermott’s VP for Asia Ian Prescott said.
“The success of this project confirmed that our consortium with LTHE has performed well in delivering the best in-market solution for our client.
“We look forward to building on this strategic collaboration for future projects in India.”
