The marine environment creates a set of challenges for hydraulic hose and fittings that don’t exist to the same degree in land-based applications.

Salt water and salt air are highly corrosive to standard steel hydraulic fittings and end connections. In a marine environment, standard carbon steel fittings that would last for years in an industrial application can deteriorate rapidly, leading to fitting failures, hydraulic oil leaks, and the safety and environmental risks that come with them. Using the right materials from the outset is not optional in marine hydraulic installations. It is the difference between a system that performs reliably for years and one that requires constant attention and early replacement.

UV exposure is another significant factor for hoses and external components on vessels operating in Queensland’s climate. Prolonged UV exposure degrades the outer cover of standard hydraulic hose over time, leading to surface cracking that, while initially cosmetic, eventually compromises the structural integrity of the hose assembly.

Vessel movement introduces dynamic loading conditions that differ from stationary industrial applications. Hose assemblies on vessels need to be routed and supported to accommodate the movement of the vessel without creating stress concentrations at end fittings or chafe points against vessel structure.

Access is also a practical challenge in marine hydraulic work. Hydraulic components on vessels are often installed in confined bilge spaces, engine rooms, and machinery compartments where access is restricted and working conditions are cramped. Experience with marine hydraulic installations and the patience to work carefully in confined spaces matters enormously in delivering a quality result on a vessel.

Hydraulink Brisbane North carries the right materials for marine hydraulic applications and our technicians understand the specific requirements of working on vessels and marine equipment in the Brisbane North region.
