Page 41 of 72 June 2017 / st 41 T here's a lot of discussion in the maritime industry about the Internet of Things (IoT), but we often hear an undercurrent of skepticism about what big data can really do for a vessel. Here's one scenario: Imagine you are the shore-based fleet operator for a dozen world- voyaging commercial vessels. One of your 1,000-ft. freighters is pulling away from the coast of Norway at the start of a jour- ney to Newfoundland, which is to say it will soon be in a vast ocean thousands of miles from port. An alarm pops up on your computer showing erratic ac- celerometer data on one of the vessel's systems, consistent with excessive vibration on a propel- ler. You immediately run a data analysis program, determine that the propeller is indeed within a few hundred rotations of failure, and put in a call to the vessel captain to return to port, just 50 nautical miles away, for a repair. Had the propeller failed on its own time, the vessel would have been crippled in the middle of the north Atlantic, prompting several hundred thousand dollars in emergency services, not to mention the cost of lost voyaging time. For exploration or research vessels, a similar dilemma could interrupt work at a crucial juncture, sacrificing valu- able time and dollars, and potentially forcing an expedition to be cancelled. What will it take to ensure that timely monitoring and alerts become part of a seagoing operation's everyday real- ity, no matter the size of the fleet or sophistication of the vessels? To make this type of service truly groundbreaking, it Developing a Maritime Internet of Things Service Big Data Analytics for Remote Vessel Monitoring, Operations By Bob Balog • Robert Hopkins • John Croy A pair of KVH satellite antenna domes is installed high up on a Seacat Services vessel that provides support for wind farms located off the coast of European countries, including Eng- land, Denmark and Germany. The two KVH systems used on this vessel are the TracPhone V3-IP, providing satellite Internet connectivity, and the TracVision M3, providing satellite televi- sion programming. This type of vessel can benefit from sensor- based analytics that alert ship operators and support techni- cians to potential issues with the vessel systems so equipment can be kept in optimal condition for maximum vessel avail- ability.
