巴西石油公司与 Allseas 公司签订合同，为位于巴西里约热内卢近海 230 公里处的超深水 Ataptu-2 盐下油田开发项目提供基于刚性立管的海底解决方案。

该合同涵盖在水深超过2000米的海域设计、采购、建造和安装143公里长的刚性立管和输油管线。该海底管网将通过采用“波浪形”配置的钢制悬链式立管，把18口油井连接到一座新建的FPSO（浮式生产储卸油装置）。合同范围还包括用于完成连接的关键部件，例如柔性接头、管道末端接头和跨接线。海上作业计划于2029年第一季度开始，将由Allseas公司的铺管船“Audacia”号执行。

Petrobras contracted Allseas to deliver a rigid riser-based subsea solution for the ultra-deepwater Ataptu-2 pre-salt field development, 230 km offshore Rio de Janeiro, Brazil.

The contract covers design, procurement, construction and installation of 143 km of rigid risers and flowlines in water depths exceeding 2000 m. The subsea network will connect 18 wells to a new FPSO via steel catenary risers in a “lazy wave” configuration. The scope also includes critical components such as flex joints, pipeline end terminations and jumpers to complete the connections. Offshore work is scheduled to begin in Q1 2029 and will be executed by Allseas’ pipelay vessel Audacia.
