TGS Kicks Off Second Phase of Equatorial Margin Survey off Brazil
within the Pará-Maranhao Basin, one of the world’s largest, most unexplored, and highly prospective basins.PAMA Phase II extends coverage by approximately 11,500 square kilometers, including blocks currently under nomination for upcoming license rounds scheduled for 2026 and 2027.A Ramform Titan-class vessel started data acquisition early June and is expected to complete the survey early March 2026. The vessel is equipped with TGS GeoStreamer technology, ensuring high-quality 3D seismic acquisition and data delivery. The project is supported by industry funding.The Pará-Maranhao Basin
US Coast Guard Displayed Ingenuity and Resourcefulness in Titan Response
The catastrophic implosion of the Titan submersible that killed five people in 2023 could have been prevented, a US Coast Guard investigative board found on Tuesday, calling the vessel’s safety culture and manager OceanGate's operational practices “critically flawed.”The Titan vanished during a descent to the Titanic wreck on a tourist expedition, losing contact with its support ship. After a tense four-day search, its shattered remains were discovered strewn across the seabed 1,600 feet (488 meters) from the bow of the wreck.The report includes information on the US Coast Guard
Inadequate Design, Certification and Maintenance Led to Titan Disaster

Teledyne Valeport Water Announces Shallow Water Hyperion32
for users who don’t require deep-sea capability. Its 32 mm diameter housing also offers a lighter, more compact form factor, making it ideal for a broad range of water quality monitoring applications where space, ease of deployment are key considerations.The Hyperion range, named after the Titan god of light, is an industry leading suite of optical sensors, packaged in Teledyne Valeport’s signature Titanium housings, offering precise measurement of a number of parameters. With the Hyperion32, Teledyne Valeport Water delivers the same trusted optical performance found in the original
Bayesian Yacht Disaster: How Specialist Search and Rescue Teams Work Underwater
migrants on unseaworthy boats. Then there are issues related to mechanical difficulties, such as the Argentinian San Juan submarine in 2017, and plane crashes such as the still-missing Maylasian Airlines MH370 plane in 2013.Finally, there are searches for missing divers or underwater craft like the Titan submersible which imploded during a dive to the Atlantic wreck site of the Titanic in 2023.Diver cautionThe search for the missing in the sunken Bayesian yacht – the cause of which is currently uncertain – should have been relatively straightforward. Helicopters, likely equipped with
Two PGS Vessels Kick-Start Surveys Offshore Norway
Norwegian seismic company PGS has started seismic survey operations in the northern hemisphere, using two Titan-class Ramform vessels and an ultra-high-res 3D spread.PGS’ Ramform Tethys has picked up the reins on the 2024 Norwegian Sea GeoStreamer X survey, adding new coverage and a new layer of understanding in this exploration hotspot.Acquisition design includes wide-towed sources and dense streamers for improved near-offset distribution, and also long streamer tails for accurate velocity model building.By the end of the season the PGS data library will offer around 20 000 sq. km of GeoStreamer
PGS Secures 3D Contract in South Atlantic
Marine seismic data company PGS has received a letter of award for a large 3D contract offshore South Atlantic margin from a multiclient company.A Ramform Titan-class vessel is scheduled for mobilization in June, with a forecast acquisition duration of up to 300 days.The value of the contract has not been disclosed, but PGS announces contract awards with a value of $10 million or more, multiclient projects with a duration of 2 months or more, and strategically important contracts.“Seismic activity offshore South Atlantic margin is increasing as a result of recent exploration success, and we are
PGS Hooks Northern Europe Seismic Deal
Northern Europe summer season for the Ramform Tethys. By combining the Ramform acquisition platform with our proprietary multi-sensor GeoStreamer technology we will quickly provide the client with high-quality 4D seismic data,” said Rune Olav Pedersen, President & CEO in PGS.Ramform Tethys is a Titan-class ship as 24 streamer reels, 16 abreast with a further 8 in a second row.This allows the vessel to take full advantage of our GeoStreamer technology and perform acquisition of high-volume exploration 3D, or high-density 3D or 4D seismic data
Glamox to Light Up PGS’ Seismic Vessels
of the eight vessels.PGS’s switch to energy-efficient LED lighting is being driven by its desire to comply with emission reduction targets, new regulations, and its own sustainability targets.The LED luminaires will be fitted into eight vessels that operate worldwide: Ramform Vanguard, Atlas, Titan, Hyperion, Tethys, Victory, Sovereign, and PGS Apollo.The vessels undertake seismic surveys to gather geophysical data to create detailed maps of sub-surface conditions. This information is used by offshore energy and mineral companies, and increasingly by offshore wind farm developers to determine
