.... The system is capable of detecting small leaks of production or hydraulic fluid (ppm levels) over distances of 4–5m in a subsea environment. Ideally, systems designed for such applications should be capable of working at depths of up to 3000m unattended for periods of 20-plus years. The system uses advanced...

.... To address this, this paper reviews the case for secure, high reliability acoustic signalling through water, with applicability to communication requirements for the subsea industry. Nautronix Acoustic Subsea Communication (NASCoM) NASCoM is the name given to the family of products discussed in this paper...

... it differs from conventional tone based acoustics and how it provides improved performance and cost-savings in existing subsea acoustic control, monitoring and positioning applications. Drawing upon Sonardyne's real-world experience, it provides examples of data from some recent offshore projects...

... for most applications. This creates component compatibility problems, because the melting points are higher than for lead/tin solder, and reliability issues, as contamination between processes results in poor solder bond strength. The implications for obsolescence management is that suppliers are making...
