There are three primary ways to haul a vessel out of the water. These include using a floating drydock, a graving dock, or a marine railway. Other methods are used to haul vessels such as travel lifts and synchrolifts.
Moving cranes on wing walls of drydocks and marine railway equipment (such as winches, carriage, and stiles) exposes workers to crushing and caught-between hazards. Assessments need to be conducted to protect employees from fall hazards.
