The Tui Project oil field, located off the coast of New Zealand, has entered its third and final phase of decommissioning. The project, which began in 2007, has been a joint venture between four companies: Tamarind Taranaki Ltd, Cue Taranaki Pty Ltd, NZOG Taranaki Ltd, and Pan Pacific Petroleum. The oil field has been in operation since 2007 and has produced over 40 million barrels of oil.
Phase 1 of the decommissioning process involved the removal of all production equipment from the Tui oil field. This included the removal of the FPSO Umuroa, which was used to store and process the oil produced from the field. The FPSO was towed to Singapore for recycling.
Phase 2 of the decommissioning process involved the plugging and abandonment of all wells in the Tui oil field. This was completed in 2019 and involved the use of a drilling rig to plug and abandon each well. The wells were then capped with cement to prevent any leakage of oil or gas.
Phase 3 of the decommissioning process involves the removal of all subsea infrastructure from the Tui oil field. This includes pipelines, umbilicals, and other equipment that was used to transport oil and gas from the wells to the FPSO. The removal of this infrastructure is expected to take several months and will involve the use of a specialized vessel equipped with cutting tools and cranes.
The decommissioning of the Tui oil field is an important step in ensuring the safety and environmental sustainability of the area. The removal of all production equipment and subsea infrastructure will eliminate any potential hazards associated with the operation of the oil field. It will also allow for the restoration of the area to its natural state.
The Tui Project oil field decommissioning is a complex process that requires careful planning and execution. The joint venture partners have worked closely with the New Zealand government and regulatory authorities to ensure that the decommissioning is carried out in a safe and environmentally responsible manner.
In conclusion, the Tui Project oil field decommissioning entering Phase 3 is a significant milestone in the process of decommissioning the oil field. The removal of all subsea infrastructure will ensure the safety and environmental sustainability of the area, and allow for the restoration of the area to its natural state. The joint venture partners have worked closely with the New Zealand government and regulatory authorities to ensure that the decommissioning is carried out in a safe and environmentally responsible manner.
