Ship Underwater Radiated Noise – Course Instructors
Dr. Lorenzo Moro (Module: Fundamentals of Ship Noise)
Dr. Lorenzo Moro is an Associate Professor and Department Head (acting) in the Department of Ocean and Naval Architectural Engineering at Memorial University of Newfoundland. In 2007, he graduated in Naval Architecture and Marine Engineering at the University of Trieste, Italy. After graduation, he started his research in ship structural dynamics and ship noise and vibration at the Ship Noise and Vibration Laboratory. He collaborated closely with industry partners, such as Fincantieri S.p.A. and Wärtsilä. After completing his doctoral studies in Trieste in 2015, he moved to Canada and joined the ONAE Department as an Assistant Professor. Since then, he has worked on noise exposures of fish harvesters and performed extensive research to understand noise propagation on fishing vessels and provide effective and feasible solutions to mitigate any hazardous noise levels. He has also worked on methods to measure underwater noise from ships, including using autonomous underwater gliders and methods to characterize ships as sources of underwater noise to identify any sources of noise pollution and develop design solutions to mitigate them. Dr. Moro is a Chartered Engineer in the UK (CEng) and a member of SNAME and RINA. He has been a member of technical committees of the International Ships and Offshore Structures Congress since 2012.
Layton Gilroy (Modules: Propeller and Appendage Noise, Sources and Transmission of Vibrations)
Layton Gilroy is a Senior Defence Scientist with Defence Research and Development Canada (DRDC) with expertise in the fields of underwater acoustics, ship noise, and ship signature management. Mr. Gilroy has been with DRDC for over 34 years and has led research programs in ship signatures, signature management, and composite ship propellers. He has been involved in international collaborations and led several sea trials to measure ship noise and vibrations and has been advising Transport Canada under their Quiet Vessel Initiative for the last several years.
Daniel Alvarez (Module: Underwater Radiated Noise Modelling and Prediction)
Daniel Alvarez holds a Master of Science in Engineering Acoustics from the Technical University of Denmark and 20 years of experience in advisory roles in maritime and offshore sectors. In Lloyd’s Register (LR) from 2006, Daniel successfully managed numerous projects related to noise and vibration assessments, predictions, and control. Daniel currently leads the LR advisory operations regarding noise and vibration with a particular focus on the environment, namely underwater noise and the contamination caused by vessels when operating in the vicinity of ports and terminals. Moreover, Daniel supervises several vessel projects where underwater noise predictions are included as part of the design.
Michael Bahtiarian (Modules: Underwater Radiated Noise Measurements, Underwater Radiated Noise Reduction Strategies)
Michael Bahtiarian, is a Principal with Acentech, Inc. In Cambridge, MA. Mr. Bahtiarian is a board-certified noise control engineer by INCE-USA with over 25 years of experience in designing and testing quiet ships. These have included the first quiet research vessels in the United States; the NOAA Fishery Research Vessels (FRVs), U.S. Navy AGOR-24 Class oceanographic research vessels (R/V Neil Armstrong and R/V Sally Ride), and the University of Delaware R/V SHARP. Mr. Bahtiarian was the technical facilitator for the Underwater Vessel Noise Reduction Targets (UVNRT) initiative supported and coordinated by Transport Canada to develop underwater radiated noise limits for individual ships. He was also the chair of two different standard committees that produced the first two standards for the measurement of underwater noise from ships; ANSI/ASA S12.64 and ISO-17208-1. Mr. Bahtiarian is a principal with Acentech, Inc., a multi-disciplinary acoustics, noise, vibration and technology consulting firm in Cambridge, Massachusetts. He is the 2018 Distinguished Noise Control Engineer, former president, and fellow of the Institute of Noise Control Engineering (INCE-USA).
