The code’s final compliance deadline is 13 December 2026, introducing mandatory continuous whole-body vibration (WBV) monitoring and a formal Safety Management System (SMS) under Annex 8 for all UK workboat operators, including those serving offshore wind. The WBV requirement imposes real-time assessment against ISO thresholds during every voyage, obliging skippers to reduce speed, alter heading, change route, or document justification when exposure approaches the action value—a shift from periodic survey-based checks to data-driven, auditable operational decisions.
