Subsea Monitoring
Monitor and Evaluate can be the correct choice. In situations where leaks have occurred, or there is damage/dehydration to subsea infrastructure, it is possible to monitor the situation and carry out ongoing evaluation as part of the remediation measures. EV has manufactured and supplied real time subsea monitoring systems that allow Clients to do this remotely.
EV's subsea monitoring system follows a standard outline design involving key components that can, if required, be tailored to suit the specific application and quickly rolled out. The 5 main components are:
- Subsea Camera and Lighting system
- Subsea Control Module
- Subsea Umbilical
- Autonomous Buoy with transmit / receive capability
- Remote Control Unit / Display
The subsea camera and lighting systems are designed to limit the onset of marine bio-fowling using UV lights and wipers to ensure that constant imaging is possible. The cameras are mounted to the existing subsea structure and fitted with variable focus and zoom.
The subsea control module that feeds the cameras and lights with power and receives the imaging data can be placed on the seabed and is connected to the surface by a two way umbilical that permits control signals to be passed to the Subsea Control Module and digital image data sent up to the Buoy. Powered by batteries recharged by wind or solar power (or both), the Buoy is fitted with a two way digital data transmission system that can send and receive data remotely over distances of up to 15km, or longer if required. Existing battery capability permits the remote system to operate for 15 days without solar or wind recharge.
Real time data can be received in a remote control room on a permanent installation. Operators also receive condition monitoring data from the Buoy and SCM. They can send commands to the SCM to vary cameras and light settings if required. The data received can be interpreted to determine whether there is deterioration with time.
The system can also be tied back to existing Subsea Control Modules in place as part of the subsea infrastructure.
EV can supply this system as part of an emergency response or ensure one is available as part of contingency planning.
