Oceaneering lines up six months of offshore survey work
Oceaneering's Ocean Intervention II wins multi-discipline survey contracts offshore Trinidad and in the US Gulf of Mexico.
Houston-based Oceaneering International has secured multi-discipline offshore survey contracts for its Ocean Intervention II vessel to support offshore development programs for an undisclosed international operator.
Under the contract, the company will deliver integrated geophysical, geotechnical and autonomous survey services offshore Trinidad and in the US part of the Gulf of Mexico. The program is expected to span approximately six months, with options for additional work and extensions.
Offshore Trinidad, the work scope includes 2D and 3D seismic data acquisition, high-resolution and ultra-high-resolution seismic surveys, seabed mapping and geotechnical investigations. Geotechnical activities include seabed sampling using box cores and piston cores, while the scope also encompasses AUV surveys in deeper water areas and shallow-water surveys using towed conventional geophysical systems. Operations in Trinidad are expected to last approximately four months.
In the Gulf of Mexico, Ocean Intervention II will conduct geotechnical investigations, AUV-based block surveys and pipeline inspections. Pipeline inspections will incorporate non-contact cathodic protection measurement technology integrated with the AUV. These operations are expected to span approximately two months, with options for additional site and block surveys.
"By consolidating multiple survey scopes onto a single vessel and crew, Ocean Intervention II supports single-pass and simultaneous operations that reduce campaign duration, minimise mobilisations, and shorten offshore exposure, improving efficiency and lowering overall emissions compared to traditional multi-vessel survey programs," said Peter Buchanan, Oceaneering's senior director for surveys, products and services. Owned by Oceaneering, Ocean Intervention II was purpose-built for geophysical and geotechnical surveys and underwent significant upgrades in early 2025 to support simultaneous, multi-discipline survey operations.
