Brazilian state-owned operator Petroleo Brasileiro (Petrobras) has started decommissioning works on the P-12 platform in the Campos Basin offshore Brazil.

The company started P-12 decommissioning after approval from the Brazilian National Agency for Petroleum, the Brazilian Institute for the Environment and Renewable Natural Resources, and the Brazilian Navy.

The P-12 platform is located at the Linguado field, 83km from Cabo de São Tomé in a water depth of 100m.

As per the company’s strategic plan for 2020-24, a total of 18 production platforms will be decommissioned by the year 2024.

The P-07 and P-15 platforms in the Campos Basin are also scheduled for decommissioning in this year.

Built in 1977, the P-07 platform was last upgraded in 2002. It is located 120km off the coast from Macaé at the Bicudo field, in water depths of 210m.

The P-15 semi-submersible was built in 1983. It is located at the Pirauna field, 127km off the coast of Macaé, 243m deep.

In a press statement, Petrobras said: “The decommissioning of the platforms will be carried out in accordance with the best global practices.

“In partnership with other companies and with the scientific community, methodologies that allow the identification of the alternative that best balances safety, environment, technical, social and economic aspects were developed.”

The bidding session for the P-07, P-12 and P-15 platforms is scheduled to commence this month.

Last month, Petrobras started oil and gas production at the Atapu shared deposit in the eastern portion of the country’s Santos basin.

In May this year, Petrobras released its Q1 financial results, showing its worth fell by $13.4bn as part of a cash impairment charge.

In April, Petrobras revised its debt reduction plans due to the ongoing fall in crude prices as a result of the Covid-19 pandemic.
