West Natuna Exploration Limited has awarded Timas Suplindo an engineering, procurement, construction and installation contract covering the subsea umbilical, flowline and riser scope for the Mako gas project offshore Indonesia.
West Natuna Exploration Limited, a majority-owned subsidiary of Conrad Asia Energy, operates the Duyung production sharing contract with a 76.5% interest. Project partners are Empyrean Energy with 8.5% and Coro Energy with 15%. The companies reached a final investment decision for the Natuna Sea development in March.
The initial phase of the Mako project will include six development wells tied back to a leased mobile offshore production unit with a design capacity of 172 mmscfd. Gas production will be transported through an approximately 59 km, 18-inch export pipeline to the KF platform in the adjacent Kakap PSC before entering the WNTS pipeline network for delivery to Indonesia’s domestic market.
Under the agreement, Timas Suplindo will carry out FEED verification and detailed engineering work for the SURF system. The scope includes flowlines, the export pipeline, risers, subsea structures, umbilicals and installation engineering.
The Indonesian contractor will also oversee procurement of contractor-supplied materials together with the management, storage and integration of line pipes, umbilicals, SPCS equipment and subsea valves.
The contract also covers fabrication and assembly activities for subsea structures and SURF components, followed by inspection and testing before offshore installation. In addition, Timas Suplindo will manage load-out, transportation and offshore installation work for flowlines, risers, subsea structures, umbilicals and tie-ins.
Pre-commissioning activities include cleaning, gauging, hydrotesting, dewatering and leak testing. The contractor will also support West Natuna Exploration Limited during commissioning and start-up operations.
Conrad Asia Energy Managing Director and Chief Executive Officer Miltos Xynogalas described the agreement as an important milestone for the Mako project as it advances into the execution stage and said the company looks forward to working with Timas Suplindo on the development.
