According to Upstream, the selected PMC contractor will be required to oversee various works in line with the project scope onshore and offshore. This includes engineering services, project control services, construction services, sustainability and permitting services, as well as procurement services.

The PMC work, expected to be completed in 24 months, will be carried out in Jakarta, the Tangguh LNG plant, and other locations approved by BP.

Companies interested in submitting bids must have experience managing engineering, procurement, and construction for offshore and onshore oil and gas facilities. Additionally, Tangguh LNG operators must meet a local content requirement of 70%.

The development of Ubadari consists of two new offshore platforms, installed at depths of about 20-25 meters, along with a 4-kilometer-long corrosion-resistant alloy (CRA) subsea pipeline with a diameter of 12 inches to transport gas from the sea. This will be connected to a 72-kilometer-long, 24-inch CRA pipeline from the platform to the existing Train 3 Tangguh onshore receiving facility.

For the Vorwata field, an offshore EGR platform needs to be installed at a water depth of about 40 meters, which will receive CO2 via a 12-kilometer-long, 12-inch CRA pipeline from the shore. The scope of Vorwata also requires onshore collaboration with the existing Tangguh acid gas disposal unit.

Ubadari is targeting first gas in Q3-2026, while the Vorwata project is scheduled to start operations the following year.

As a note, in August 2021, the government approved the Tangguh project development plan, including the exploitation of the Ubadari gas field, EGR through CCUS in the Vorwata field, and onshore compression.

The Tangguh Block, which began operations in 2009, currently has a production capacity of 11.4 million tons per year, following the recent operation of the third train.

Last year, the government approved a 20-year extension until 2055 for the Tangguh Block, consisting of the Berau, Muturi, and Wiriagar contracts.
