32 Proceedings Summer 2014 www.uscg.mil/proceedings Since many of the tests are intrusive for passengers, tests that would directly affect passengers were conducted while the ship was in port. The vessel surveyors were extremely knowledgeable and took the time to explain each system in great depth to us, sharing priceless insight into their processes. As such, this opportunity greatly expanded our profciency and provided invaluable information. About the authors: LT Kevin Whalen is a 2009 graduate of the U.S. Coast Guard Academy. He works as a marine investigator at USCG Sector Miami and previously served as a marine inspector at USCG Sector New York, where he received his foreign passenger vessel examiner qualifcation. LT Whalen holds a B.S. in marine and environmental science and an M.A. in management and lead- ership. Chief Warrant Offcer Van Huysen is a senior marine inspector at USCG Sector New York and is a qualifed foreign passenger vessel examiner. He previously served on two aids to navigations teams at a Coast Guard small boat station and as engineering petty offcer aboard the Coast Guard cutter Crocodile. Authors' note: Special thanks to DNV-GL surveyors, Mr. Christos Aspiotis and Mr. Bharat Madan, and Lloyd's Register surveyors, Mr. C.K. Chan and Mr. E. Buoso. In-Depth Testing Transitional Power Test During our surveys, we witnessed the transitional power test that verifes that the emergency source of power is able main- tain electricity to critical systems during the time between loss of power and when the emergency generators come online. To test for a worst-case power scenario, surveyors purposely prevent the emergency generator from coming online. The Safety of Life at Sea Convention (SOLAS) requires certain systems to function under transitional power. Additionally, SOLAS mandates that the batteries conform to a maximum voltage drop of less than 12 percent. Surveyors walked through the ship to verify required systems such as water-tight doors operated, internal communications worked properly, navigation lights burned brightly, general alarms sounded, fre alarms activated, sprinkler section valves worked properly, and emergency lighting worked. Water-tight Door Test We also witnessed closing water-tight doors remotely via bridge control. This SOLAS requirement allows the crew to safely close water-tight doors remotely to secure the ship if an emergency arises. Remote Operating Valve Test Lastly, being able to witness testing remote operating valves provided a better understanding of all the systems and how they can be controlled. The system is so advanced that it lets the engineer know if the valve is closing, closed, open, or not fully closed due to an obstruction. It also features a safety redundancy that allows engineers to operate the valve locally during an emergency. (Pictured on previous page.) Views of transitional power battery banks.
