Reducing Operational Hours for Subsea7 with Unparalleled Real-Time Connectivity
Hydromea’s key customer, Subsea 7, a global leader in the delivery of offshore projects and services for the energy industry, has successfully deployed LUMA technology on several deep-water pre-commissioning campaigns. The result - reduced vessel time infield and improved overall project efficiency.
“Using Hydromea’s LUMA technology provided access to hydrotest data which would otherwise require recovery via ROVs – a time-consuming and thus costly exercise. During pre-commissioning campaigns, Subsea 7 continually seek project efficiencies and the LUMA modems offered significant reductions in operational time by allowing real-time evaluation of a hydrotest prior to depressurizing the system. We are planning further pre-commissioning works using LUMA 250LP technologies in 2024, and look forward to exploring further opportunities to improve subsea operations using optical communications.” MILTON HOOKS, Principal Pre-Commissioning Specialist, Subsea 7
AT A GLANCE
Hydromea’s LUMA systems provide users with a host of solutions for subsea data transfer challenges. Using cutting-edge optical technology which is designed to be easily integrated into existing equipment, it provides high-speed wireless communications delivering more productive projects for its customers.
THE SOLUTION
Subsea 7 paired LUMA 250LP modems with a subsea data logger to output the internal pressure and temperature readings recorded during pipeline pressurization testing. This information was captured and relayed to surface using ROV systems deployed at depths exceeding 1,500m. They transmitted critical test data in real-time to the surface, allowing immediate access to the information without the need to physically recover the data loggers.
BENEFITS
Enhanced Reliability
Data was previously obtained using short electrical flying leads to connect the ROV. This method proved unreliable due to either water ingress or ROV damage - LUMA technology reduced the risk of data retrieval issues.
Reduced Operational Time & Cost
Real Time Data
Founded in 2014, Hydromea is a Swiss-based technology company delivering solutions that allow customers to have near real-time high-speed and high-volume data access in the subsea environment. Hydromea’s unique expertise lies in three complimentary underwater technology areas: wireless communication networking, robotics and navigation.
