Subsea Oilfield Communications

Robust and highly reliable subsea communication systems are required to safely and efficiently control a wide range of subsea applications from Blow Out Preventer (BOP) controls to subsea processing and well-head instrumentation. Long subsea tie-backs and networked links to adjacent fields, coupled with the introduction of more sophisticated and data-intensive sensors, are driving the need for higher speed communication solutions with advanced data traffic management and diagnostics.

For the past 30 years, Focal has committed to developing and supplying advanced technologies for our customers in the marine market. Leveraging our expertise with field proven communication and networking technologies from the ROV market, we design, test, and manufacture a wide range of ISO 13628-6 qualified subsea control products including fiber optic modems, Ethernet switches, sensor data interfaces, and condition monitoring. Reliability and availability are optimized with robust designs, redundancy options, extensive diagnostics, fault tolerant protocols, and extensive qualification. We provide both standard and customized systems for critical subsea applications with options for card-level and packaged solutions.

Focal’s experienced engineering staff will work closely with customer’s Engineers to provide requirements and standards compliance, specialized documentation, obsolescence management, and firmware maintenance.
