Shearwater Geoservices has announced a deep-water ocean-bottom node (OBN) survey contract in West Africa, marking a significant milestone for offshore data collection in the region.
Scheduled to commence in Q4 2024, this one-month survey will be the first of its kind to leverage the SW Tasman vessel’s advanced seismic source and dual remotely operated vehicle node deployment capabilities in a single-vessel operation.

The survey will introduce to West Africa Shearwater’s proprietary Pearl node technology, a compact and high-endurance system renowned for its performance.
Since its launch last year, the Pearl node has been in continuous operation, demonstrating its reliability and effectiveness in offshore data acquisition.
Shearwater CEO Irene Waage Basili said: “This project demonstrates yet another operational advantage of our Pearl/Tasman OBN platform. Following its successful mobilisation in India in early 2024 and the recently announced Angola projects through late Q2 2025, this award showcases the platform’s growing impact in complex offshore environments.
“By combining the Pearl node and our unique multi-function SW Tasman vessel, we enhance survey efficiency and unlock the potential of deep-water OBN surveys in environments where cost barriers historically have been too high.”

By GlobalDataShearwater Geoservices also secured its second OBN survey project with TotalEnergies in Angola last month.
The three-month deep-water survey, set to focus on the Golfinho and Cameia fields, will commence in October and utilise the Pearl node technology.
The SW Tasman vessel, equipped with dual ROVs, will be deployed for this operation, showcasing its specialised capabilities in seismic node-laying.
TotalEnergies previously awarded Shearwater the first OBN survey contract for Block 32 in the Louro and Mostarda fields, with the deep-water survey due to start in January 2025.
This project, expected to last approximately two and a half months, follows Shearwater’s successful completion of a 4D streamer survey for TotalEnergies in the same area.
