NOV has executed a contract to supply a second APL Submerged Swivel and Yoke (SSY) system for Southern Energy SA’s floating LNG (FLNG) project in the Gulf of San Matías, offshore Argentina.

This follow-up award builds on SESA’s ongoing FLNG development plans and reflects the company’s confidence in APL’s subsea mooring and transfer solutions. The project will utilize Golar’s MK II FLNG design with a capacity of 3.5 million tonnes per annum (MTPA). With two FLNG units, Argentina is expected to export up to 6MTPA of LNG.

This project builds on APL’s joint development with Golar to evolve the SSY system for harsher environments.

The APL SSY is designed to provide safe mooring and uninterrupted gas transfer via subsea pipeline. By removing the need for a jetty, the system aims to reduce topside infrastructure, lower project complexity, and enable SESA to deliver LNG to market more efficiently, addressing key customer challenges in offshore export developments.

NOV is well-positioned to supply proven technologies that improve efficiency and accelerate the execution of FLNG projects.
