Oceaneering Launches Comprehensive Offshore Survey Campaign
Oceaneering International, a pivotal player in the subsea services sector, has embarked on an extensive multi-discipline offshore survey campaign using its upgraded vessel, Ocean Intervention II (OI2). This initiative, executed on behalf of a “large international operator,” spans the dynamic waters of offshore Trinidad and the U.S. Gulf. With operations commencing in April, the campaign is set to run for approximately six months, featuring integrated geophysical, geotechnical, and autonomous survey services.
The Role of Ocean Intervention II
The OI2, a 77-meter-long research vessel originally launched in 2000, has undergone significant enhancements in 2025 to facilitate simultaneous and multi-discipline survey operations. These upgrades include advanced survey systems, dedicated launch and recovery capabilities for autonomous systems, and modernized data infrastructure. This means the vessel is not only equipped to collect a wealth of data but is also capable of doing so in a more efficient manner compared to traditional survey methods.
Operations in Trinidad
In Trinidad, OI2 is primarily tasked with a variety of essential operations. These include:
- 2D and 3D Seismic Data Acquisition: Vital for understanding subsurface geological structures.
- High-Resolution Seismic Surveys: These offer enhanced detail for better planning and decision-making.
- Seabed Mapping and Geotechnical Investigations: Critical for infrastructure development and environmental assessments.
The operational activities will involve seabed sampling via box cores and piston cores, in addition to employing autonomous underwater vehicles (AUVs) for surveys in deeper waters. Towed conventional geophysical systems will be utilized in shallower areas, collectively reinforcing the thoroughness of the exploration. The timeline for these operations is expected to last approximately four months.
Expansive Efforts in the U.S. Gulf
Transitioning from Trinidad to the U.S. Gulf, OI2’s scope of work will shift slightly. Here, it will focus on:
- Geotechnical Investigations: Essential for evaluating conditions for potential offshore developments.
- AUV-Based Block Surveys: These facilitate detailed inspections and mapping of specific areas.
- Pipeline Inspection Activities: Ensuring the safety and integrity of existing pipelines in a high-traffic region.
The expected duration for these campaigns is around two months, with the possibility for additional site and block surveys being offered based on needs.
Efficiency and Environmental Considerations
Oceaneering has emphasized its commitment to operational efficiency and environmental sustainability. As Peter Buchanan, Oceaneering’s Senior Director of Survey, Products, and Services, noted, the focus on consolidating multiple survey scopes onto a single vessel means reduced campaign durations, minimized vessel mobilizations, and less offshore exposure. This approach is not only cost-effective but significantly lowers overall emissions compared to conventional multi-vessel survey programs, marking a step toward greener practices in the offshore sector.
The Future of Offshore Surveys
With OI2 at the forefront, this offshore survey campaign sets a precedent for future operations, integrating advanced technologies while addressing the ever-evolving needs of the energy sector. The simultaneous operations facilitated by the enhanced vessel are a testament to the innovations driving the industry toward more efficient and sustainable practices.
As Oceaneering continues to build trust with its international clients, the successful execution of this comprehensive survey campaign could lay the groundwork for similar projects around the globe, amplifying the company’s reputation as a leader in subsea exploration and services.
