Engineering, procurement, construction, installation, and commissioning company Timas Suplindo has won the subsea umbilical, flowline, and riser (SURF) tender at Conrad Asia Energy’s (ASX:CRD) Mako gas field in Indonesia’s West Natuna Sea.
Timas will verify front-end engineering and design, as well as execute detailed engineering designs for the SURF system. This includes flowlines, export pipeline, risers, subsea structures, umbilical, and installation engineering.
Timas will also procure all contractor furnished materials. It will manage, store, and integrate line pipes, umbilical, subsea pipeline commissioning systems, subsea valves, and company furnished materials.
Along with these, the company will fabricate, assemble, coat, inspect, and test subsea structures and associated SURF components.
It will manage load-out, transport, and offshore installation of flowlines, export pipeline, subsea structures, risers, umbilical, and tie-ins.
Timas will also perform cleaning, gauging, hydrotesting, dewatering, and leak testing. It will likewise support Conrad subsidiary West Natuna Exploration during commissioning and start-up.
A formal contract signing ceremony was held at the Shangri-La Hotel in Jakarta on 7 May 2026.
“Securing this agreement is a major milestone for the Mako project and underscores our continued progress into the execution phase. We are very pleased to be working with Timas on this key element of the development,” Conrad Managing Director and CEO Miltos Xynogalas says.
The mobile offshore production unit has a design capacity of 172 million standard cubic feet per day. Sales gas will be transported via a 59km-long and 18-inch-wide pipeline to the keyframe fixed platform in the adjoining Kakap production sharing contract.
It will then pass through the West Natuna transportation system pipeline for the Indonesian domestic market.
Total capital expenditure to first gas is estimated to be US$320 million ($441.9 million). There is a US$35 million provision for owner-supplied equipment to be novated to the mobile offshore production unit provider, plus potential down payments.
Annual future operating and pipeline transportation costs are targeted to range between US$70 million and US$80 million.
Conrad Asia Energy is a natural gas explorer and producer with assets mainly off the shore of Indonesia.
