Oslo-listed seismic data company TGS has secured a high-end 4D streamer contract offshore Angola.

The survey programme is scheduled to begin acquisition activities in early July 2026. The contract is expected to run for approximately eight months.

According to TGS, the award improves the company’s strategic position in the Africa region and provides visibility for one vessel into the first quarter of 2027.

The Angola contract follows two offshore survey awards in the Norwegian North Sea announced by TGS last week.

One of the contracts covers 4D streamer operations using a Ramform Titan-class vessel. That campaign is scheduled to start in late July and continue for around 45 days.

The second contract is for ocean bottom node (OBN) work, with mobilisation planned for June and an expected duration of about 25 days.
