        该作业于4月启动，包括由OI2在特立尼达和美国墨西哥湾提供综合地球物理、岩土工程及自主水下调查服务，为期约6个月，并附有额外工作及延期的可选条款。

 

        在特立尼达，该船负责二维和三维地震数据采集、高分辨率和超高分辨率地震调查、海底测绘及岩土工程勘察，岩土作业包括使用箱式取样器和活塞取样器进行海底采样，以及在较深水区进行自主水下航行器（AUV）调查，并在浅水区使用拖曳式常规地球物理系统开展作业。作业预计持续约四个月。

 

        在美国墨西哥湾，OI2将进行岩土工程勘察、基于AUV的区块调查及管道检测活动，历时约两个月，并附有额外场地和区块调查的可选任务。

 

        “我们感谢客户对我们能力的信任，相信我们能够交付可靠、综合的调查作业，并针对其项目需求进行定制。通过将多项调查工作整合到单一船舶和船员团队上，OI2支持单次通过和同步作业，从而缩短作业周期、减少动员次数、缩短海上暴露时间——相比传统的多船调查方案，这提升了效率并降低了整体排放，”Oceaneering高级总监——调查、产品与服务业务负责人Peter Buchanan表示。

 

        Oceaneering于2025年对这艘2000年下水、长77米的研究船OI2进行了升级，以使其能够执行同步、多学科调查作业。升级内容包括调查系统改进、自主系统专用布放回收能力加装，以及数据基础设施现代化。

The program started in April and includes OI2 delivering integrated geophysical, geotechnical, and autonomous survey services offshore Trinidad and the U.S. Gulf for approximately 6 months, with options for additional work and extensions.

 

In Trinidad, the vessel is in charge of 2D and 3D seismic data acquisition, high-resolution and ultra-high-resolution seismic surveys, seabed mapping, and geotechnical investigations, geotechnical activities such as seabed sampling using box cores and piston cores, as well as autonomous underwater vehicle (AUV) surveys in deeper water areas and shallow-water surveys using towed conventional geophysical systems. Operations are expected to last approximately four months.

 

In the U.S. Gulf, OI2 will perform geotechnical investigations, AUV-based block surveys, and pipeline inspection activities, spanning approximately two months, with options for additional site and block surveys.

 

“We appreciate our customers’ trust in our ability to deliver reliable, integrated survey operations tailored to their project needs. By consolidating multiple survey scopes onto a single vessel and crew, OI2 supports single-pass and simultaneous operations that reduce campaign duration, minimize mobilizations, and shorten offshore exposure—improving efficiency and lowering overall emissions compared to traditional multi-vessel survey programs,” said Peter Buchanan, Oceaneering’s Senior Director – Survey, Products and Services.o

 

Oceaneering in 2025 upgraded the 77-meter-long research vessel OI2, launched in 2000, to perform simultaneous, multi-discipline survey operations. The enhancements included survey system upgrades, dedicated launch and recovery capability for autonomous systems, and modernized data infrastructure.
