Offshore & Marine

As Founder of Great Circle Offshore, Sanjai brings over 30 years of experience in the marine and offshore oil and gas industry, as a Master Mariner on a variety of merchant vessels including tankers, container ships and bulk carriers before transitioning to the offshore industry as Captain on dynamically positioned multi-support diving and construction vessels. He has worked in various offshore areas of the world, including GoM, Australia, New Zealand, India, South China Sea, Indonesia, West Africa and the Far East.

Sanjai has had considerable experience with the installation and repair of floating production units (Semis, FPSO’s, FSO’s, MODU’s) and subsea flexible and rigid pipelines during his tenure on offshore construction vessels. He was the project manager for various installations in the Zafiro Field off Equatorial Guinea including the FPSO Zafiro Producer, FSO Harrier and FSO Magnolia. Sanjai was the Installation Manager for Kerr McGee’s Red Hawk Cell Spar and Murphy Oil’s Kikeh Truss Spar in Malaysia during his tenure with Technip Offshore Inc.

In 2006, Sanjai rejoined Aker Solutions to help grow their marine contracting division in the US. Sanjai headed up the marine contracting division (Aker Marine Contractors US) for Aker Solutions in North America holding responsibility for operations, engineering and project management including operation of AMC chartered and owned construction vessels. During this time the major deep water projects completed were the installation of the Blind Faith semi-submersible for Chevron, Thunderhawk submersible for Murphy Oil and the Kwae Nkrumah FPSO in Ghana for Anadarko/Tullow Oils. Aker Solutions was awarded the Noble TAMAR project offshore Israel with AMC being responsible for delivery of all subsea equipment, umbilicals and installation of the same.

In 2011, Sanjai was part of the transition team when Aker Marine Contractors was acquired by EMAS Singapore. He was responsible for all projects and operations in the newly created EMAS AMC division in Houston and was also the project manager for the PSVM FPSO that was installed in the deep waters off Angola
