UTEC Survey, an Acteon company and one of the world’s largest independent offshore and onshore survey providers, has successfully completed a significant ROV navigation and seismic node positioning project in deepwater Gulf of Mexico.
The project, carried out for seismic nodal technology leader FairfieldNodal and undertaken in 2425 metres of water, involved use of the latest software and navigation technologies available to simplify operations, increase cost savings on an original scope of work, provide greater precision, increase efficiencies and thereby reduce job time.
UTEC conducted the project using a combination of acoustics and inertial positioning technology. A key element was the creation of an improved navigation software package incorporating the latest NavView technology from data and positioning analysis expert 4D Nav. The system provided enhanced and precise positioning awareness along with the management of inertial sensors and a bespoke link to FairfieldNodal’s data acquisition system.
The innovative, real-time software enabled UTEC to integrate three separate positioning modules into one comprehensive package to increase efficiency and streamline user operations. It also provided enhanced graphics capabilities, following the replacement of existing online navigation, inertial navigation and node management software.
UTEC Regional Manager (Americas) Dave Ross says, “The successful completion of this project underlines the value in applying innovative solutions to increase operational efficiency and address costs, which is critical in the modern industry. Our excellent relationship with 4DNav meant that we were able to provide a bespoke solution to FairfieldNodal, which exceeded expectations, eliminated the need for multiple computers, streamlined activities and created a much more efficient operation. We are delighted at the successful outcome achieved by this exciting solution.”
