Marine Gear Units
RENK offers a comprehensive range of marine gear units from reversing gear units starting at 1,000 kW to complex gear units arrangements for naval vessels with 40,000 kW and more of transmitted power, including all requisite control and monitoring systems.
Many of today’s ships are equipped with CODAD (COmbined Diesel And Diesel) and CODOG (COmbined Diesel Or Gas turbine), CODAG (COmbined Diesel And Gas turbine) or COGAG (Combined Gas turbine And Gas turbine) propulsion plants. Special Cross Connect gears and CODELAG (COmbined Diesel ELectric And Gas turbine) units, for propulsion plants with electric motor and gasturbine propulsion complete the product range.
The T2RECS is a single-stage modular marine gear unit for single or twin screw vessels intended for offshore work (OSV, AHTS, PSV, etc.), commercial duties (MPV, container feeders, etc.), and the fishing industry.
Modular design: The modular gearboxes come in 7 sizes with center distances of 400-710 mm, ratings of 500-5000 kW, torque transmission ratios of 2:1 to 7.7:1 and engine speeds of 500 – 2.200 rpm.
* Power Take –Off (PTO): For driving a generator for onboard power
* Power Take-Inn (PTI): For additional booster power from a generator/electric motor
* Power Take-Home (PTH): Redundant propeller drive system via a generator/electric motor
Easy maintenance: The T2RECS is easy to maintain due to split housing. Quick access to the pinion shaft and multiple disc clutch is an added benefit when servicing in addition to the fact that the thrust bearing can be replaced without opening the housing. Easy dismantling of all the hydraulic components during maintenance is a final touch.
Robust design: Each gear unit is computed twice: according to the requirements of the classification society and according to RENK’s own regulations.
High quality: RENK’s own in-house standards ensures high-quality macro- and micro-geometries for the case-hardened helical gearing to ensure quiet, smooth running and extended longevity.
* Reduction of the main engine speed to the optimum propeller speed
* Power take-off (PTO) or power take-in (PTI) for or from auxiliary drives
Double Marine Gearbox
* Combination of individual power of several main engines.
* Reduction of the main engine speed to the optimum propeller speed.
* Power Take-Off (PTO) or Power Take-In (PTI) for or from auxiliary drives.

Maritime Hybrid Drive
MARHY® is used for economical and environmentally friendly propulsion for slow steaming and maneuvering through its Power-Take-Home (PTH) function. The system also offers Power-Take-Off (PTO) and Power-Take-In (PTI/Booster).
MARHY® can be used on any type of vessel with Fixed Pitch or Controllable Pitch Propeller (FPP or CPP), with a propulsion power of up to 60 MW. PTO/PTH/PTI power will be adapted in accordance to each specific project requirement.
The MARHY® package consists of RENK Propeller Shaft Clutch (PSC), RENK tunnel gearbox, Highly flexible couplings and Electric package (Electrical motor/generator, Frequency converter with harmonic filters as well as digital control & monitoring system).
Integrated Front-end Power System (IFPS)

Developed for front-end mounting it can be applied where there
is no space for other PTO solutions arranged between the main
engine and the propeller. As the space on the front-end is in most
cases also limited, the system features a flat gear unit design and
specially designed short generators.
The gear unit is connected to the crankshaft via an intermediate
central shaft and a highly elastic coupling. The angle encoder of
the main engine is mounted to the coupling cover.
