NEW ORLEANS – Seabed Geosolutions has introduced FlexNode, a scalable node deployment solution, at the 2015 Society for Exploration Geophysicists Annual Meeting. An express seabed seismic service, FlexNode has completed two successful projects for different operators, with one located offshore West Africa and the other in the North Sea.
Through its transportable, modular solution, nodes can be deployed using existing support vessels already on site, which Seabed Geosolutions says helps keep clients within budget constraints while optimizing vessel usage. At the show, representatives from the CGG and Fugro joint venture told Offshore that the FlexNode service solution is designed for deepwater projects up to 3,000 m (9,842 ft) under tight time constraints, and projects where targets are obstructed by platforms and seafloor infrastructure.
While the number of nodes to be deployed can be flexible, Seabed Geosolutions said that between 200-500 nodes are typically needed, as FlexNode offers sparse node geometry with a high-density shot point coverage.
Currently, customers could employ Seabed Geosolutions' existing Trilobit in using FlexNode, a four-component broadband seabed node which already offered prolonged recording times and flexibility in deployment methods. However, the company representative explained, by 2H 2016, the company is planning for its new fully-autonomous Manta node to be available. This model could also be used in the FlexNode service.
