BASARAN manufacture and supply 3 pcs OUTBOARD PROPULSION UNITS to work boats the owner is Marmara Pilotaj and Romorkaj Ltd. Company.
Outboard propulsion units are self-contained thruster packages for main propulsion and positioning of barges, platforms and river craft. They are available with diesel or electric hydraulic drives with power ratings from 15 hp to 1,000 hp. Conversion from a simple barge or unpowered vessel can be done in as little as a few hours to less than a week without modifying the hull. The hydraulic drive is especially suited for shallow, brown water applications where debris in the water or shallow bottoms can be a problem.
The hydraulic drive provides fully proportional propeller speed control in forward and reverse while the engine runs at constant speed. Many options are available, including hydraulic kick-up of the out-driver, hydraulic propeller depth adjustment, remote control panels, choice of engines, etc.
Model OP outboard drive assembly includes the steering motor, drive and stem rotation mechanisms, outboard stem, propeller hydraulic motor, propeller, nozzle, and the outboard tilt mechanism, if fitted.
Hydraulic Power Tilt System (Optional)
The Model OP series propulsion unit for transom mounting can be provided with an optional hydraulic power tilt system capable of elevating the outboard drive assembly through an arc of 90 degrees. Hydraulic oil supply for the power tilt mechanism is supplied by a steering and tilt hydraulic pump. Power tilt hydraulic cylinders and piston rods are constructed of suitable alloys to prevent marine atmospheric corrosion. The cylinders are of sufficient volume and stroke to provide the full 90 degree arc of the outboard drive while subjected to full propeller thrust loading. The hydraulic power tilt system incorporates cross-port relief valves that allow the outdrive assembly to kick up in the event it encounters a subsurface obstruction or in the case of grounding.
The Model OP propulsion unit is equipped with a manganese-bronze, four-blade, high-thrust, Kaplan accelerator-series mono block propeller contained in a Kort Type 19A thrust nozzle. The nominal diameter, blade pitch and disk area ratio of the propeller is selected to provide either maximum static bollard thrust or maximum thrust at design vessel speed.
