UTEC Geomarine completes Caspian Sea projectProjects and Operations // June 26, 2015
UTEC Geomarine, the geotechnical service line of UTEC Survey, has completed the first phase of a geotechnical site investigation in the Caspian Sea for a major oil and gas operator.
The project was completed using a cost-effective, time-efficient suite of remotely operated vehicle (ROV) conveyed technology, comprising of UTEC’s patented geoROV seabed cone penetration test (CPT) and sampling system, geoREACT suction skid, and a specially developed rotary core drill.
geoROV technology is an ROV-compatible, CPT, T-bar and push sampling tool. Key benefits include portability, cost-effectiveness and productivity. The geoROV returns high quality soils data at any water depth (depending on ROV).
The geoROV drive unit mounts to all work class ROVs and after initial mobilisation takes less than one hour to fit or remove. It can be deployed alongside or in between other subsea ROV works, and provides realtime data transmission.
geoREACT, an ROV tool skid designed to provide additional stability and reaction force for seabed investigation, enabled testing and sampling to take place over the full range of seabed types on this project.
geoROV has a well-established track record in investigating drill cutting mounds beneath live platforms; establishing geotechnical parameters for design of subsea infrastructure in congested brownfield sites (adjacent to or beneath existing infrastructure); grid-style investigation to provide assurance of ground conditions for gravity base design; investigating geohazards; and conventional route surveys.
