Seabed Geosolutions to Perform Santos Basin Survey

Seabed Geosolutions has secured a letter of award to provide a 3D ocean bottom node (OBN) survey in 2,000 m of water in the Santos Basin, offshore Brazil.The 410-square-kilometer survey, which has a contract value of more than $50 million, will be performed for a prominent energy company using Seabed Geosolutions’ proprietary Manta OBN technology and remotely operated vehicles. The four-component (4C) project will begin in the second quarter of 2020 and will take around 4 months to complete.Stephan Midenet, CEO of Seabed Geosolutions, said, “We are excited to work with a pioneer in ocean-bot

A Seismic Shift Towards Quieter Surveys

, it’s use is highly regulated. Many countries use UK-based Joint Nature Conservation Committee guidance, which will see activity delayed if a marine mammal is detected within 500m. The Australian National Offshore Petroleum Safety and Environmental Management Authority has a 1-3km zone, while in Brazil and Ireland it’s 1km. There are also other bodies with their own guidance as well as country specific regulations. Most mean having onboard mammal observers and towed passive acoustic monitoring (with PAM onboard unmanned vessels also emerging). Some countries have even banned seismic exploration

Sonardyne Equips Brazilian Research Vessel

Science equipment and underwater vehicles deployed from Brazil’s flagship oceanographic research vessel, Alpha Crucis, are to be tracked using Ultra-Short BaseLine (USBL) positioning technology supplied by Sonardyne Brasil Ltda.The 64-meter-long vessel, which is operated by the University of São Paulo, undertakes research projects spanning global climate change to biodiversity in Brazilian waters. It will be equipped with a Sonardyne Ranger 2 USBL high precision acoustic positioning system to enable the Alpha Crucis’ 21-strong science team to precisely track their instruments and

This HB PIRARARA shallow-draft pusher tug and sister vessel HB PIRARUCU have a Robert allan RApide 4000-Z3 tug design and were constructed by Estaleiro Rio Maguari in Belem, Brazil.Computational Fluid Dynamics (CFD) simulations were used in the early phases of the design work to optimize the hull shapes and minimize total convoy resistance, and the Z-drives fitted in customized tunnels designed to optimize flow and propulsion efficiency while reducing draft. This resulted in

DOF Subsea Upgrades ROV Fleet

Subsea services provider DOF Subsea has equipped a further three of its Brazilian offshore vessel fleet with hybrid acoustic and inertial navigation technology from Sonardyne Brasil Ltda.Sonardyne’s SPRINT-Nav all-in-one subsea navigation instruments are now supporting five Forum Energy Technologies (FET) remotely operated vehicles (ROV) on board the three vessels. This latest order takes the total number of DOF Subsea’s Brazilian vessels equipped with SPRINT-Nav aided ROVs to six.SPRINT-Nav combines Sonardyne’s SPRINT sensor, Syrinx 600 kHz Doppler velocity log (DVL) and a pressure

Oil Price Controls Subsea Market Growth

through 2025 – close to 20% of spending in the subsea equipment and SURF segments is at risk, while around 10% of general oilfield services market spending is at risk should the oil price fall from our base case estimate to $50 per bbl.Examining the subsea spending risks more closely, we see that Brazil has several projects with breakeven prices around $50 per barrel.Spending at risk is largely dominated by floater projects globally, but in Norway is manifested in subsea tieback projects. No fewer than 16 projects with subsea expenditure between 2019 and 2025 are at risk on the Norwegian continental

The company also expanded its global reach with more than 17 locations and 10 shore bases around the world, including in the UK, US, Norway, Brazil, Asia Pacific, and Australia. In 2019, InterMoor continued the roll-out of the IM Release and successfully released the first set of the acoustic release connectors offshore Mexico. The IM Release is a new acoustic release mooring connector, that builds on their track record of designing and installing
