Frames said on Monday that the subsea wells and valves would be used as part of a tie-back of the Merakes field to the existing Jangkrik floating production unit offshore East Kalimantan, Indonesia.

The gas from the field will be shipped through the existing pipelines from the Jangkrik FPU to the Bontang LNG processing facility.

The company said that it would supply a production HPU, a topside umbilical termination unit, and a subsea isolation valve control panel.

Together these systems will enable the control and operation of the subsea wells and subsea isolation valves for the Merakes field. The Frames’ production HPU is suitable for pressures up to 459 bar.

It will allow autonomous control of the PHPU while still enabling an operator to temporarily take control using a local interface during scheduled preventative maintenance.

Thomas de Wolf, product specialist well sites, HIPS, and hydraulics at Frames, said: “This is a fast-track project where close collaboration is essential. We have worked with TechnipFMC on many similar projects and so they know our extensive experience and capability with these systems.”

We should remind that TechnipFMC won a large integrated EPCI contract from Eni for the Merakes project in late March. The value of the deal is between $500 million and $1 billion and that it covers five deepwater wells and their 50-kilometer tie back to the existing Jangkrik FPU.

The company’s project scope includes engineering, procurement, installation and pre-commissioning of subsea equipment such as subsea trees, a manifold, large bore deepwater high-pressure flexible lines, umbilicals and distribution hardware, flexible risers, flowlines and jumpers.

The Merakes field, located in the East Sepinggan PSC in the Makassar Strait, is estimated to hold about 2 trillion cubic feet of lean gas in place.

Eni received an approval of the plan of development (POD) for the Merakes field from the Indonesian Minister of Energy in April 2018.

In December 2018, Eni’s investment plan for the Merakes field was authorized by the company’s board of directors.
