Minor UK Tsunami After Massive sub-Atlantic Slide

A minor tsunami occurred in the last week of June 2011 along the south coast of the United Kingdom. A network of coastal tidal and wave monitoring stations maintained by Southampton-based EMU Limited recorded the progress of the waves beleived to have been caused by a massive underwater landslide in the Atlantic, 200 hundred miles off the Cornish coast. Waves of between 0.5 and 0.8 metres resulted in abnormal tidal records at the Channel Coastal Observatory and Plymouth Coastal Station shore stations. A massive underwater landslide in the Atlantic 200 miles off the Cornish coast is believed to be the... (read more)

WHOI Ship 'Atlantis' Participates in Missing Argentinian Sub Search

The research vessel 'Atlantis', operated by Woods Hole Oceanographic Institution (WHOI), was diverted on 21 November 2017 to help search for the missing Argentinian submarine ARG 'San Juan' and has been participating in the search since then. 'Atlantis' was en route to a planned oceanographic mission in the South Atlantic when U.S. Navy officials directed it to head to the area where communications were last received from the sub. The advanced research vessel arrived in the area at 2 p.m. on 21 November and immediately began search operations using the ship’s multibeam sonar and underwater communications systems. The ship also... (read more)

Robotic Underwater Vehicle for Ocean Bottom Seismometers Positioning

The versatility of Hydro-Lek’s HyBIS robotic underwater vehicle has been further demonstrated in the deployment of Ocean Bottom Seismometers (OBS) and Ocean Bottom Electromagnetic Receivers (OBEM) on the seafloor in the Arctic Ocean. The expedition was conducted by members of the Marine Geology team from Southampton’s National Oceanographic Centre (NOC) to collect data from sites of methane gas and seafloor gas vents. HyBIS, a mnemonic for Hydraulic Benthic Interactive Sampler, is a 6,000m-rated, fully modular, electro-hydraulic platform designed to operate in conjunction with existing deck handling and cable systems. The vehicle comprises an upper command and power unit with a... (read more)

Seabed Geosolutions Wins Red Sea Ocean Bottom Node Contract

Seabed Geosolutions and its partner have been awarded a 3D ocean bottom node survey in the Red Sea. The S-79 project will require the acquisition and processing of high-quality 3D data over a large area in various water depths. Seabed’s highly efficient 4C Manta ocean bottom nodes will be used, in combination with its best-in-class ROV deployment system in deep waters and node-on-a-wire system in shallower areas. The surveys are scheduled to commence early 2019. Stephan Midenet, CEO of Seabed, said “We are very pleased to partner with ARGAS in order to provide services to Saudi Aramco on this high...

K.U.M. and the SEA-SEIS Ocean-bottom Seismometer Deployment Mission

Capturing the Earth’s Heartbeat
Scientists from the Dublin Institute for Advanced Studies (DIAS) have undertaken a 21-day marine science mission, deploying 18 ocean-bottom seismometers (OBSs) at a series of locations on the floor of the North Atlantic Ocean. The OBSs function as sensors and are to record the tiny vibrations of the Earth caused by seismic waves, generated by earthquakes and ocean waves, and will record these vibrations for the next 18 months. The intended outcome of this mission is to collect data that will enable the DIAS scientists to better understand the activity under and on the ocean floor along Ireland’s west coast,... (read more)

Fugro to Buy Seabird's Ocean Bottom Nodes Business

As outlined in a Letter of Intent, Fugro will acquire SeaBird Technologies AS, Norway, and Seabed Navigation Co Ltd. which collectively hold all of SeaBird's rights and assets related to the Ocean Bottom Node (OBN) business. The agreed acquisition price is USD125 million on a cash and debt-free basis.     As part of the contemplated transaction, Fugro has already acquired 11% of SeaBird Technologies AS and Seabed Navigation Co Ltd. Fugro will also charter source vessel capacity from Seabird to support the OBN operations. Currently SeaBird is mobilising for a USD40 million OBN contract for ONGC. The OBN method... (read more)

Fugro’s AUV Images Bring Search for Lost Sub AE1 to Successful Close

Fugro’s role in an expedition to find HMAS AE1 has helped to solve Australia’s oldest naval mystery, 103 years after the First World War Australian submarine vanished off Rabaul, Papua New Guinea. In waters over 300 metres deep, Fugro deployed its autonomous underwater vehicle (AUV) from Survey Vessel 'Fugro Equator'. On 19 December 2017 an object of interest was located, and further inspection confirmed that it was AE1. Using specialised survey technology, including a multibeam echosounder mounted on the hull of Fugro Equator and its AUV, Echo Surveyor 5, Fugro scanned the seafloor to collect detailed data. The AUV flew... (read more)

Seabed Geosolutions Secures 3D and 4D Ocean Bottom Node Contracts

Seabed Geosolutions has been awarded a 3D ocean bottom node (OBN) seismic acquisition project over the greater Angostura field in shallow waters offshore Trinidad for BHP, and a 4D OBN project for Shell Nigeria Exploration and Production Company. The combined awards are valued at around US60 million.  The 225 km2 Trinidad project will start in the first quarter of 2018 and will use Seabed Geosolutions’ latest node handling solutions deployed by ROV. These subsea systems were developed together with Fugro. BHP’s plans for development in the area require a step-change in seismic quality, which can only be provided by OBN data. Stephan...

2D and 3D Ocean Bottom Node Seismic Survey for Total

Seabed Geosolutions, headquartered in The Netherlands, has secured a two-year contract with Total E&P for its Ocean Bottom Node seismic data acquisition technology. The contract utilises a ‘call-out’ mechanism for each acquisition survey with the option to extend the contract for an additional 24 months. The initial work programme consists of approximately 5 months of 3D and 2D surveys and will commence in the UK Sector of the North Sea in the fourth quarter of 2013 upon completion of a current West Africa survey. The multiple survey areas will be acquired with Seabed Geosolutions’ deepwater Trilobit technology and robotic modularised... (read more)
