Assessing Noise Exposure on Offshore Support Vessels: Implications for Crew Health and Safety

Abstract

This study examines the impact of noise exposure on crew members aboard an offshore vessel supporting wind farm operations in the North Sea. Noise measurements were conducted during both navigation and dynamic positioning modes. The study focuses on noise levels in various compartments and their impact on crew health, especially the risk of hearing loss, sleep disturbances and fatigue. The results show that despite compliance with international standards (e.g., IMO MSC.337(91)), some crew members, especially those working in the Engine Department, are exposed to noise levels exceeding EU Directive 2003/10/EC limits. Voluntary notation classes focus primarily on accommodation spaces and fail to enforce the recommended 40 dB(A) limit for restful sleep. The study underscores the importance of addressing noise levels to improve safety and crew well-being, especially in areas such as cabins and workspaces.
