Subsea system computers are essential to the speed and accuracy of underwater scanners. They deliver imagery for applications including wreckage surveying and underwater construction. Dependable computers support rapid response rates, allowing end-users to retrieve and analyse information almost instantly and support immediate decision making.
If a computer does not operate reliably, transmissions are at risk of both being delayed or misinterpreted by the user. It is essential that subsea computing platforms are designed and engineered towards satisfying application requirements over a sustained timeframe. Equipping computers with the latest generation processors and imaging technologies will ensure these platforms perform at optimum speeds and deliver the highest quality onscreen graphics for rapid and simplified analysis.
Subsea sonar surveyors are deployed across a wide range of tasks, ranging from oil and gas to decommissioning and salvage. The systems are operated for prolonged periods of time, making a constant and consistent provision of power crucial. Subsea computers can be specified with integrated power outputs. This means they act as a single point of connection between additional surveying peripherals, reducing subsystem power supplies as well as unnecessary cable runs.
Marine computers must operate in unclean and challenging environments and require specific levels of protection to ensure the safety of the product and the operative. Protection can be offered through application of design and engineering expertise to incorporate features such as dust filters, robust chassis and wide operating temperatures to counteract hostile conditions. In addition, long life component selection and carefully applied obsolescence management can assist in extending operational life.
While it is not a requirement to certify subsea computers to industry standards, testing for EMC and thermal emissions is a means to further ensure reliability throughout their lifecycle. This culminates in minimal interference with other systems, a reduced need for maintenance and minimal servicing.
