Harbour Energy, through its subsidiary Premier Oil Natuna Sea, is advancing its operational plans for the Natuna Sea Block A production sharing contract offshore Indonesia by initiating a contractor prequalification process for the charter of anchor handling tug supply (AHTS) vessels. These vessels are required to support drilling activities scheduled for 2026 on this producing asset.

Vessel Specifications and Contract Details

The AHTS vessels must possess a minimum bollard pull of 100 tonnes and be equipped with DP2 dynamic positioning capability. Both Indonesian and foreign-flagged vessels are eligible for consideration. The estimated contract term is one year, with a projected start date in June or July of the following year. A significant local content (TKDN) requirement of 85% is mandated, and bids will be accepted from domestic and national companies or consortia.

Prequalification Process and Deadlines

Prospective bidders must register by submitting a statement of interest and collecting the prequalification documents via email before the deadline of 15.00 local time (08.00 GMT) on 2 December. The final submission deadline for the prequalification documents is 10 December. Interested companies are required to be registered with the Indonesian upstream regulator SKK Migas' CIVD (Centralised & Integrated Vendor Database) for Oil and Gas and must possess a valid SPDA (Certificate in Lieu of Administrative Documents) at the time of document submission.

Asset Overview and Production Context

The Natuna Sea Block A PSC, where Harbour Energy holds a 28.7% operated interest, contains several fields, including Anoa and Pelikan, as well as the Bison, Iguana and Gajah Puteri (BIGP) project, which commenced production in November 2019. The company successfully amended its gas sales agreements with Singaporean buyers last year, implementing a tiered pricing structure that increased the take-or-pay commitment and facilitated higher production levels in the second half of 2024. Harbour's Indonesian output averaged 5000 barrels of oil equivalent per day last year. Gas from the block is exported to Singapore via the West Natuna Transportation System, while the produced oil is sold to Indonesia's domestic market. The other partners in the block are Kufpec, Petronas, and Pertamina.
