Marine Works Safety Awareness Overview
Marine construction takes place in and around tidal waters, rivers, harbours, and coastal environments. Workers face unique hazards including drowning, tidal forces, vessel movements, cold water shock, and the additional challenge of working from floating plant on unstable platforms. Weather and tidal conditions dictate the working window and can change rapidly. Every operative on a marine construction site must be trained in water safety and understand the specific emergency procedures for the marine environment.
- Wear an approved personal flotation device at all times when working near or over water.
- Check tidal predictions daily and plan all work within the safe tidal working window.
- Ensure rescue equipment including throw lines and lifebuoys is positioned at all water-side work areas.
- Provide water safety induction training covering drowning prevention and cold water shock awareness.
- Brief all workers on the man overboard procedure and the location of rescue equipment.
- Use barriers and edge protection on all quays, jetties, and floating platforms.
- Monitor weather and sea state conditions continuously and stop work if conditions deteriorate.
- Ensure vessel movements are coordinated by a competent marine coordinator during all operations.
- Maintain communication with the harbour master or port authority as required for the location.
If someone falls into the water, shout 'man overboard', throw a lifebuoy immediately, and call 999 and the coastguard on VHF channel 16. Do not enter the water unless trained and equipped for water rescue.
- Drowning is the primary fatal risk on marine construction sites and prevention starts with PFDs.
- Cold water shock can incapacitate a person in under 60 seconds regardless of swimming ability.
- Tidal conditions change constantly and working windows must be strictly followed.
- Never position yourself between a vessel and a fixed structure where crushing injuries occur.
- Man overboard procedures must be briefed and practised regularly before any marine work begins.
- Weather deterioration at sea is rapid and unpredictable — monitor conditions continuously.
