Jetty and Wharf Construction Safety in WA — Standby Rescue Vessel Requirements
Jetty and wharf construction is one of the highest-risk over-water activities in Western Australia. Workers are regularly positioned directly over water at varying heights — driving piles, installing decking, fixing structural steel, and carrying out marine civil works in environments where a fall into the water is a constant hazard.
For project managers and HSE teams planning jetty or wharf construction in WA, having the right standby rescue vessel arrangements in place is not just a compliance requirement — it is an essential part of keeping your crew safe.
Why jetty and wharf construction presents unique water safety challenges
Jetty and wharf construction environments create a specific set of water safety challenges that are different from other over-water work settings:
Workers are positioned at varying heights over the water throughout the project duration — from ground level at the water's edge to elevated positions on pile frames and decking structures
The confined space between pile clusters and structural elements makes it difficult for larger rescue vessels to operate effectively
Tidal movement and current can carry a casualty away from the work area quickly
Multiple workers may be in the water simultaneously in the event of a structural failure or scaffold collapse
Construction activity creates noise and visual obstructions that can delay the identification of a fall-into-water incident
What WA legislation requires
Under the WA Work Health and Safety Act 2020, PCBUs conducting jetty and wharf construction must have appropriate rescue arrangements in place for all over-water work. This includes a documented rescue plan specific to the site and the construction activities, appropriate rescue equipment, and qualified rescue personnel available for the duration of the works.
For jetty and wharf construction, a standby rescue vessel is the most effective and practical control measure for a fall-into-water emergency.
Why a PWC is the right vessel for jetty and wharf construction
A PWC rescue vessel is particularly well suited to jetty and wharf construction environments. It can manoeuvre quickly in the confined spaces between pile clusters and structural elements where larger vessels cannot operate, reach a casualty in the water within seconds of an incident, operate effectively in shallow nearshore and tidal environments, and be launched and retrieved quickly without crane infrastructure.
For projects where multiple workers are over water simultaneously — common during peak construction phases — having a dedicated PWC rescue vessel on standby provides the most reliable and responsive rescue capability available.
