Oslo-listed seismic specialist TGS has secured an ocean bottom node (OBN) contract offshore Namibia from an undisclosed repeat customer, adding a significant deepwater survey to its 2026–2027 work programme. The contract was awarded on an undisclosed basis, and no financial terms were disclosed. A deepwater crew is scheduled to mobilise in the fourth quarter of 2026, with the survey expected to run for approximately 120 days, extending crew employment into the second quarter of 2027.
Ocean bottom node technology is typically deployed in deepwater environments where conventional towed-streamer acquisition is constrained by existing infrastructure or complex seabed terrain. OBN surveys generate high-fidelity subsurface images that operators use to refine reservoir characterisation ahead of appraisal and development drilling decisions. The identity of the client has not been disclosed, though TGS described the customer as a repeat buyer, suggesting an established commercial relationship in the basin.
Namibia's offshore sedimentary basins — particularly the Orange Basin — have attracted substantial operator interest following a series of significant hydrocarbon discoveries in recent years. Multiple international majors and independents hold acreage, and ongoing appraisal activity has sustained demand for high-resolution subsurface data. The TGS contract reflects continued investment in pre-development data acquisition as licence holders advance their understanding of discovered resources and evaluate development concepts.
TGS, headquartered in Oslo and listed on the Oslo Stock Exchange, is one of the world's largest providers of multi-client and proprietary seismic data. Its OBN capability positions it to serve operators requiring premium acquisition solutions in technically demanding deepwater settings. The company did not disclose the specific block location or the survey area's dimensions in its announcement.
The 120-day survey duration indicates a programme of meaningful scale, consistent with the type of detailed appraisal or field-development imaging work that typically precedes final investment decisions in frontier deepwater plays. Completion in the second quarter of 2027 would align processed data delivery with what could be active development-planning windows for several operators active in Namibian waters. The contract reinforces Namibia's position as one of sub-Saharan Africa's most active frontier deepwater provinces for seismic and subsurface services.
