The Britannia P&I Club has highlighted the risks of hydraulic oil leaks in the marine industry, emphasizing the importance of proactive maintenance and risk mitigation. Hydraulic oil leaks can lead to environmental and commercial risks, particularly in port, with fines and cleanup costs posing a significant threat. Leaks from hydraulic hoses and lines near the ship’s side can be especially hazardous, as oil can spill into the sea, causing environmental damage and financial losses.
To minimize these risks, the club recommends regular visual inspections of flexible hydraulic piping and hoses, as well as prompt action to address any signs of rust, corrosion, or contamination. It is essential to replace hydraulic hoses in high-risk locations every 2.5 years and every 5 years for hoses exposed to weather. The club also recommends maintaining a record of hydraulic tank quantities to accurately determine the amount of oil spilled, should an accident occur.
In terms of design, the club suggests avoiding exposed outboard hydraulic piping and flexible hoses, and instead, considering alternative designs such as electric or pneumatic power sources, which pose lower pollution risks. For example, a shipowner replaced existing hydraulic actuators with pneumatically operated ones, while all-electric systems for cranes, hatch covers, ramps, and winches can be considered if the ship type allows.
In conclusion, the club emphasizes the importance of identifying and addressing potential pollution risks through alternative designs, proactive maintenance, and operational best practices. Failure to do so can result in environmental damage and significant commercial implications, including fines and cleanup costs. By following these best practices, shipowners and operators can reduce the risk of hydraulic oil leaks and protect the environment and their reputation.
