Seabed Surveys for EMEC

UK-based subsea services company Fathoms Ltd recently undertook two comprehensive surveys for the European Marine Renewable Energy Test Centre (EMEC) based in Orkney. The results of these surveys have enabled EMEC Ltd to extend its capabilities in the marine renewables sector, generating electricity from devices moored to the seabed.   Fathoms has recently expanded its operations to include work for clients such as Dounreay Site Restoration Ltd (to detect and recover radioactive particles from the seabed) and the Channel Coastal Observatory (National Oceanographic Centre, Southampton) collecting data to be used in a new coastal model being built to assist with...

Seabed Sampling Investigation System

In 2008, GC Rieber Shipping took a 40% strategic stake on a geotechnical survey company - Bluestone Offshore. From start-up to operational, the team based in Singapore has come a long way in the past two years between purchasing their first vessel, initiating the retrofitting work with ST Marine early November and hiring key staff with extensive experience in Health & Safety, drilling, geotechnical and laboratory analysis.     The conversion work is upgrading the Bluestone Topaz into a dedicated DP geotechnical vessel and is focused on three main areas: shift the moon pool to the center of the vessel,...

Seabed in Motion

How ripples and waves determine sand-grain movement
Despite its great practical importance, we still have much to learn about the transport of sand grains in the coastal environment. This mainly due to the complexity of sand transportation processes influenced by both waves and net currents like the tide. Here an overview of recently completed PhD research that yielded new insights into, and predictive models for, wave-induced sand transport over rippled beds. Coastal regions and shallow shelf seas like the North Sea are increasingly subjected to human activity. Cities, harbours and industry are situated near the coastline, and farther offshore the seabed is used for the construction of... (read more)

Autonomous Seabed Transponder Calibration

ASV’s C-Worker 6 successfully carried out a seabed transponder calibration in 1,300m-deep waters. The sea trials, which took place in the Gulf of Mexico, were conducted in rough conditions with 2.5m waves. ASV technical sales manager Brian Anderson said that this unmanned capability could save the oil and gas industry millions of dollars. The ability to conduct precise subsea positioning in challenging conditions broadens the possible applications for C-Worker. C-Worker is the world’s first unmanned oil and gas workboat. ASV designed and built the 6m vehicle at its waterside facility in Portchester, UK. ASV has completed the build of a... (read more)

Post-trawling Seabed Recovery

A voyage to find out what happens to seabed fauna in a deep-water trawling area if you leave it undisturbed several years got underway on 9th May 2011. The RRS James Cook set sail from Glasgow, Scotland (UK) in the direction of Rockall Trough, Rockall Bank and Hatton Basin, .     The deep-water banks and basins to the northwest of the UK are rich habitats for a variety of benthic species, including sponge reefs, cold-water coral mounds and sediment communities. At the same time, those areas form important fishing grounds for an international fishing fleet, including bottom fisheries such... (read more)

Solution for Seabed Seismic Acquisition

Five months after CGGVeritas, France, and Saudi Aramco, Saudi Arabia, signed a Memorandum of Understanding (MOU) for collaborative research and the development of geophysical acquisition, processing, analysis and interpretation technologies, the two companies have entered into a collaboration to conduct a major joint R&D project, known as SpiceRack, intended to herald a robotised solution for seabed seismic acquisition. Based on the deployment of self-propelled recording nodes, this solution is expected to lead to a step-change in the efficient delivery of reservoir quality seismic data. Both companies will draw on their seismic acquisition experience and allocate resources to the SpiceRack project.... (read more)

OSI Completes Seabed Characterization Projects

Ocean Specialists Inc (OSI), has announced the completion of a series of seabed characterization projects that involved geophysical and geotechnical surveys at selected locations in the Gulf of Mexico and Western Atlantic. OSI incorporated the survey resources of its sister company, CSA Ocean Sciences Inc (CSAOS), mobilizing a total of three separate missions under rapid planning and mobilization conditions. The Operations involved a 150ft DP-1 class vessel based in the Gulf of Mexico, as well as electronic seabed classification with the 8.5m purpose-built CSA Surveyor in the Atlantic locations.

Seabed Mapping and Inspection 2013

The annual Seabed Mapping and Inspection conference took place from 6 to 8 February 2013 in Geilo, Norway. The conference had more than 150 participants, and included people working with technology development, survey and inspection in the marine segment of the oil and gas industry. The conference was held in Geilo, a beautiful winter paradise with 39 downhill slopes and 550km cross country tracks, more or less as far away from the ocean as you can get in Norway. With generous lunch breaks allowing for skiing, or just soaking in the spa, the conference had an informal atmosphere combined with a... (read more)

Seabed Investigations off NW Australia

Fugro has been awarded a combined geophysical and geotechnical project by Hess Exploration Australia Pty Ltd (Hess) to assist in activities in the Northern Carnarvon Basin offshore Northwest Australia. Fugro’s work will comprise seabed and shallow geological investigations, including in areas of difficult terrain. For the first phase of the survey Fugro will utilise one of its Hugin 1000 AUVs to map the seabed. The data will be used to optimise planning for the subsequent sediment sampling phase where a variety of techniques will be used. Fugro’s geoconsultancy team will also deliver an integrated data model for input to Hess’s ongoing... (read more)
