At Mariner, we design, engineer, and manufacture high-performance marine equipment built to withstand the most demanding sea conditions across commercial fleets, naval vessels, offshore platforms, and commercial fishing operations worldwide.
Our advanced Rudder Systems and Steering Gear are hydrodynamically engineered to optimize vessel maneuverability and structural reliability. We offer high-lift flap type, spade type, and custom twisted rudders—with or without hydrodynamic bulbs—alongside made-to-order configurations tailored specifically for commercial fishing vessels. Built for seamless shipyard installation, Mariner rudder trunks feature integrated structural stiffeners, and we complement our maneuvering product line with bronze or synthetic neck bearing bosses, complete propeller shaft stern tube assemblies, and fully integrated steering gear systems.
For cargo handling and offshore operations, Mariner supplies a vast array of Marine Cranes designed for extreme ocean environments. Our heavy-duty above-deck machinery includes gantry, knuckle boom, service, provision, hose, davit, rescue, A-frame, and telescopic cranes, alongside specialized space-efficient below-deck bridge cranes for internal hold operations. To meet strict international safety standards, we also manufacture fully certified explosion-proof (Ex-proof) cranes tailored for hazardous commercial and naval applications.
Known globally for exceptional durability, Mariner’s Deck Winches and Capstans are engineered with either hydraulic or electric drive technology to endure severe marine loads over decades of operation. Our deck machinery range covers combined anchor and mooring winches, standalone anchor winches, self-tensioning mooring winches, towing winches, tugger winches, high-torque capstans, and specialized fishing winches built for intense operational wear.
To secure cargo integrity, our custom Hatch Covers deliver complete weather-tight protection above deck through multi-folding, double-folding, gantry-operated pontoon, external crane-operated pontoon, and piggy-back configurations. Below deck, we provide versatile tween-deck solutions and grain bulkheads designed to optimize hold space division and cargo safety according to shipowner requirements.
Finally, Mariner manufactures complete Ro-Ro Equipment and Marine Access Systems engineered to streamline vehicle, cargo, and crew access for commercial and military operations. Our heavy-duty access solutions include high-capacity stern, bow, side, and tilting marine ramps, as well as robust watertight shell doors encompassing side, stern, ROV, hangar, and pilot access doors built to precise vessel specifications.
