巴西石油公司租用的NS-42钻井平台于8月18日抵达阿马普海深水区FZA-M-59区块。该钻井平台将用于定于8月24日开始的作业前评估（APO）。作业前评估是FZA-M-59区块钻井环境许可程序的最后阶段，该区块位于阿马普海海岸175公里处，距离亚马逊河河口超过500公里。

演习期间，巴西环境与自然资源管理局 (Ibama) 将评估巴西石油公司对《野生动物保护与响应计划》和《应急计划》中概述的行动的遵守情况。通过模拟事故响应，该机构将评估设备效率、敏捷性、是否遵守预定的野生动物响应时间以及与当局和利益相关者的沟通等方面。

此次演习将有400多人参与，并将利用大型船舶、直升机以及停放在井场的NS-42钻井平台等后勤资源。通过APO，巴西石油公司将能够展示其快速行动的能力，并有资格获得该油井的钻井许可证。

这一程序与 2023 年在北里奥格兰德州近海地区实施的程序类似，当时正值 Pitu Oeste 和 Anhang谩 井钻探许可证发放之前。

The NS-42 drilling rig, chartered by Petrobras, arrived at block FZA-M-59 in the deep waters of Amapá on 18 August. The vessel will be used during a Pre-Operational Assessment (APO) scheduled to begin on 24 August. The APO is the final stage of the environmental licensing process for drilling in offshore block FZA-M-59, located 175 km off the coast of Amapá and more than 500 km from the mouth of the Amazon River.

During the exercise, Ibama will evaluate Petrobras’ compliance with the actions outlined in the Wildlife Protection and Response Plans and the Emergency Plan. Through a simulated accident response, the agency will evaluate aspects such as equipment efficiency, agility, compliance with scheduled wildlife response times and communication with authorities and stakeholders.

The exercise will involve more than 400 people and will rely on logistical resources such as large vessels, helicopters and the NS-42 drilling rig itself, which will be positioned at the well site. Through the APO, Petrobras will be able to demonstrate its ability to act promptly and will be eligible to receive a drilling license for the well.

This procedure is similar to the one carried out in 2023 in the offshore Rio Grande do Norte region, prior to the granting of drilling licenses for the Pitu Oeste and Anhangá wells.
