Complying with International Maritime Organization Resolution MSC.337(91) Noise Level CodeOne of the best things a marine operator can do for its crew or passengers is prioritize their comfort by reducing shipboard noise. Commercial and military marine vessels can be subject to very high noise levels produced by everything from onboard activities to aircraft. At worst, this noise can be hazardous—disruptively noisy environments can lead to discomfort, sleep-deprivation, and even hearing loss, which can in turn lead to lower job performance, safety risks, and diminished quality of life.

Noise Control Engineering, LLC (NCE) recently completed an underwater radiated noise study for Washington State Ferries (WSF), a study which entailed measurement of nine vessels representing all seven operating classes of WSF vessels, quantifying noise, potential impacts to orcas and other marine life, and methods of reducing noise.“With the increasing awareness of underwater noise impacts on marine life, both globally and locally in the Northwest, WSF is interested in learning more about how their operations may impact marine life,” said Jesse Spence, President, NCE.

Noise Control Engineering awarded Navy SBIR grant for abrasive blaster with reduced noise Glosten subsidiary Noise Control Engineering, LLC said it has been awarded a Small Business Innovative Research (SBIR) contract to apply advance aeroacoustics principals to the design of an abrasive blasting nozzle, reducing noise from the nozzle while simultaneously improving the device’s productivity. According to Noise Control Engineering, the nozzle developed through this effort will provide industry with a device that represents an evolutionary step forward in safety and efficiency.

Glosten subsidiary Noise Control Engineering, LLC (NCE), a Massachusetts-based acoustical and structural engineering consultancy, said it has appointed Jesse Spence as its next president. As NCE president, Spence will have direct responsibility for organizational processes, market assessment and business development. He accepts this position after serving as NCE’s director of technology. Spence joined NCE in 2001, having led the firm’s efforts to develop and implement technologies and techniques to facilitate solutions to marine acoustic and vibration problems.

Glosten is an employee-owned full-service consulting firm of naval architects, marine engineers, electrical engineers, and ocean engineers. Founded in 1958, the firm specializes in commercial and public sector vessels including research vessels, passenger/car ferries, tugs, barges, dredges, and special purpose platforms. Consulting and design services include hull, structural, mechanical, and electrical systems design. Glosten has a staff of 77 associates, including 36 professionally licensed engineers, supported by other engineers, marine designers, and production staff.

ISO 17208-1:2016, a new international standard for the measurement of underwater noise from ships, has been published by ISO. The full title of this standard is “Underwater acoustics – Quantities and procedures for description and measurement of underwater sound from ships – Part 1: Requirements for precision measurements in deep water used for comparison purposes”. The standard specifies the general measurement system, procedures, and methodology used for the measurement of underwater sound from ships under a prescribed operating condition. It is available for purchase from the ISO ans ANSI webstores. Noise Control Engineering, LLC (NCE), a leader in the field of shipboard noise control, led the effort to develop this standard.

Seattle-based naval architecture and marine engineering consultancy Glosten, Inc. has acquired Noise Control Engineering LLC (NCE), a consulting firm specializing in ship noise and vibration control. NCE, now a wholly owned subsidiary of Glosten, will continue to operate from its Billerica, Mass. and Mobile, Ala. offices as an independent group within the Glosten organization and will retain its corporate name and staff. There will be no disruption to current projects or changes in staff at either firm. “For over 55 years, Glosten has grown carefully, responding to the unique and challenging needs of our clients,” said Glosten president, Jay Edgar. “Joining with NCE is an exciting next step.

U.S. Navy’s AGOR Research Vessels are built to be as operationally quiet as possible. That’s where Mascoat’s Sound Control-dB coatings come in. When the U.S. Navy began its design and build program for its newest generation of research vessels, it specified that the vessels had to be as quiet as possible. That’s because a large part of ocean research involves listening and excessive ship noise tends to negate that effort. Achieving the goal of an exceptionally quiet vessel, the vessel’s design team employed a variety of methods to meet the Navy’s exacting standards, choosing systems, defined equipment locations and designed special installation methods with acoustics as a priority. One of those methods involved Mascoat’s Sound Control-dB coatings.

Shipping may think they hear the sound of new regulations as they are slammed onto their desks. What is all the noise concerning noise at IMO? This may very well be the question from ship owners, operators and builders closely following activities at the International Maritime Organization (IMO). In 2013, IMO issued mandatory regulations for shipboard airborne noise and earlier this year IMO internal committees approved new draft guidelines for minimizing underwater noise. Even though the author advised the U.S.
