Local private firm to deliver SURF EPCI for Indonesian gas project
What happened
WNEL and partners reached FID for the Mako gas project and contracted a local private firm to deliver SURF (subsea umbilicals, risers and flowlines) and EPCI work for six development wells tied to a leased MOPU. The scope includes fabrication, coating, testing and offshore installation plus an export pipeline to tie into existing infrastructure, making this a moving‑forward execution package rather than a high‑level plan. Watch supplier mobilisation terms, yard load‑out timing and charter availability as the next operational triggers
Buyer takeaway
Treat the Mako award as an active procurement trigger: SURF fabrication, load‑out and installation slots will be the buying levers to control cost and schedule risk
Cost / money
Cost exposure will shift toward pass‑through mobilisation items (yard berths, heavy‑lift, charters and export pipeline install) unless contracts explicitly allocate these costs
Supplier / commercial
Local EPCI providers will have leverage on timing and conditional holds during load‑out; expect requests for short quote validity and mobilisation deposits
Safety / operations
Tied‑back wells and subsea install raise HSE interface risk; insist on documented pre‑mobilisation readiness gates and supplier competency evidence before mobilisation
What to watch
Watch supplier terms on deposit triggers and any notes that conditionalise availability during load‑out and installation windows
Key facts
- Six development wells tied back to a leased MOPU
- Design capacity of 172 mmscfd for the MOPU
- Approximately 59‑kilometre export pipeline to the KF platform
