Abstract:
Abstract This paper details the evolution of reliable and cost-effective data buoy power systems used for environment monitoring applications in the Indian seas. A reliable power system is the key requirement for offshore moored buoys involved in meteorological and tsunami
monitoring missions, as unavailability of the operating power results in loss of time-critical data and can have serious impact on societal protection and, in addition, results in costly repairs and reinstallations. As a significant development and driven by stringent IEC 61508 Safety Integrity Level (SIL) standards, a Generation III power system was able to meet the required SIL 4 reliability requirements compared to the Generation I system that complied only with SIL 1. It is found that by using a suggested four slot annual maintenance plan, an operating Generation III hybrid power
system, and lead acid batteries powered by solar energy and backed by Lithium thionyl chloride batteries, in addition to meeting the required SIL 4 reliability levels, the energy cost of transmission is reduced to U.S. $1.7 per data set, compared to U.S. $2.7 in the Generation II systems. Ongoing efforts in increasing the green footprint in futuristic systems are detailed. The study provides confidence in the power system’s reliable, cost-effective and eco-friendly support to India’s Ocean Observation Network program.
