NEW ORLEANS – Fairfield Nodal is working with Shell to develop the Zlof ocean bottom node.
It is planned to be a life-of-field node, with officials from Fairfield Nodal saying that the node could operate on the seafloor for up to five years and will be able to record for up to 300 days.
A key enabling technology behind the node is Fairfield’s own high-speed optical data link. As such, darkness is necessary for the node to operate, making it ideal for deepwater.
It is sparse receiver solution, suitable for areas with large amounts of subsea infrastructure, simultaneous operations, including fields with subsea tiebacks and tension leg platforms.
An official with Fairfield Nodal that discussed the product with Offshore said that 10 Zlof prototypes will be tested by the end of next month in the Gulf of Mexico, in water depths of around 1,500-1,600 m (4,921-5,249 ft).
