Underwater Radiated Noise and Ocean Health

URNAchieving significant reductions in URN requires a multi-faceted approach. Beyond technological innovations, there is a need for stronger incentives. Ports and harbor authorities, as highlighted by the IMO, can play a crucial role in encouraging ship owners to adopt quieter technologies. The International Association of Ports and Harbors (IAPH) is already taking steps to include URN reduction in its Environmental Ship Index (ESI), rewarding vessels that minimize their environmental footprint.Local initiatives, such as Vancouver’s proactive noise-reduction schemes, demonstrate the potential for

New Wave Data Underpins Ship Structural Integrity

fatigue and the forces imposed on the hull as a result of the weather conditions.Survey requirements for some vessel types have since been tightened, but even before this tragedy, work was underway to evaluate the wave data used to determine ship structural integrity requirements. In 2016, the International Association of Classification Societies (IACS) began a re-evaluation of the scatter diagram and wave spectra that define the environmental conditions used for its wave load, fatigue, and seakeeping calculations.The resulting Version 2 of IACS Recommendation No. 34 is based on several sources of wave

One was as chairman of a Commission on Sea Level and Tides for the International Association of Physical Sciences of the Oceans. In addition, he was chairman of a body for international data called the Federation of Astronomical and Geophysical Data Analysis Services, now part of the World Data System. For all of this work, national and international, he was appointed an Officer

;Together, these allow minute changes in deep water pressure at the seafloor that indicate a tsunami to be reliably detected, triggering a direct alert to national emergency organisations via acoustic and satellite communications, all within seconds.The tsunami early warning system is fully International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) compliant and can be deployed in areas of up to 7,000 m water depth.Through the teaming agreement, MSM Ocean and Sonardyne have also agreed to explore further possibilities for combining their technologies in support of remotely
