Maritime Gear Systemsand Components

Innovative Power Transmission

The ideal solution for any drive.

RENK gear solutions combine several gas

turbines, diesel engines and electric motors,

thus enabling intelligent power management

and the implementation of a variety of

requirement profiles.

Our product range spans single reduction

(single-in/single-out) gears, as well as combined

diesel and diesel (CODAD) and combined gas

turbine (COGAG) designs. It also includes complex

combinations of several diesel, electric and/or

gas units (CODAG/CODOG/CODELAG). Our

main reduction gears also comprise multistage

gears for pure gas-turbine use and planetary

gears with coaxial power train and transmission.

RENKWE DEFINE WHAT

IS TECHNICALLYPOSSIBLE.

Our Passion: Marine Engineering.

Shipbuilding is dependent on the enormous levels

of propulsive force and transmission power of its

engines. This is the field in which RENK has always

been known for reliable, powerful, and extremely

efficient gear engineering, ever since its first marine

propulsion system in 1934. Today, our works in

Augsburg, Rheine and Hannover develop and

produce gear systems and drive components,

with great passion and expertise, which continue

to set standards in many new ways. Whatever

the type of vessel our gear systems are built for,

from naval ships to mega yachts and fast ferries,

marine ships to LNG tankers, RENK will get it

moving with the greatest of competence.

RENK WORKS IN AUGSBURG –

Special gear systems for power outputs

of 3,000 kW to over 40 MW.

At its main works in Augsburg, RENK designs,

engineers and builds special gears for naval ships,

mega yachts, fast ferries and boats for customs

and coastguards. As many as 3 nations trust

RENK to provide the gears for their naval vessels.

The largest gear system currently produced

by RENK transmits 40 MW to each propeller;

however in principle there is no limit to power

output.

Quiet gears – a must for naval and cruise shipping.

RENK has decades of experience in producing

quiet gear systems. Our expertise has made us

the most sought-after partner for international

naval applications. Today, quiet gears are a central

feature of surface combatants, where these

represent a considerable enhancement in low

noise operation.

The use of double helical gears in combination

with a precisely manufactured, load-corrected

tooth form guarantees extremely quiet operation

under full and partial load. To prevent resonation,

the design of RENK gearbox casings incorporates

the latest engineering. A further considerable

reduction in noise levels comes from specific gear

system foundations, using hard-elastic single

or double support elements of RENK patented

designs.

Outstanding features:

• Complex combining gear systems for drive

by electric motors, gas turbines and/or

diesel engines; connecting gears between

port and starboard propellers for high-output

• Weight optimised due to specific designs

• Shock resistant according to naval standards

• Low maintenance as per perfect adjustment

of components

• Unrestricted service life

• Integrated electronic control and monitoring

systems using the latest technology

Special gears for special ships such as frigates,

corvettes or coastguard vessels.

RENKAT HOME

ON THE WORLD'SOCEANS.

Our objective – no compromises on quality.

The RENK quality philosophy is applied

consistently throughout all of its works and

is the central maxim that guides all of the

company's activities, from project planning and

development to production, control, installation

and commissioning, and also including user

training and after-sales services. We use

the latest production facilities and a consistent

inspection system is in place to verify and

document product quality throughout all

stages of the production process. All finished

components are required to pass a load test

before they leave the works. The final result is

the legendary RENK reliability.

RENK WORKS IN RHEINE –

single in and double in single out gear systems

for power outputs of 1,500 kW to 35 MW.

The RENK works in Rheine designs, engineers and

produces gears for a wide range of commercial

ship types. Gears manufactured for worldwide

cargo shipping demand high levels of robustness,

reliability, safety and economy. RENK systems

fulfil these criteria in LNG carriers, container ships,

Ro-Pax ferries, tugs and supply boats and have

proven their reliability over many decades on

all oceans.

Reliability and efficiency – the success formula

for container feeder ships and LNG carriers.

Even the largest and most modern LNG carriers

in the world employ gears, propeller shaft gear

couplings and sliding bearings made by RENK.

Whether used in single or double propeller

systems, our gear units guarantee the highest

levels of reliability and economy, in all sailing

conditions and in combination with electric

motors or diesel engines alike. For constant

safe transportation across all oceans.

RENK Hannover Works –

Thrust bearings and radial bearings for shaft lines.

RENK Hannover Works designs, manufactures

and supplies bearing components for marine

applications, including thrust bearings to take

the propeller thrust and radial bearings for the

propeller shaft lines. In addition to its extensive

standard series, RENK also supplies custom-

designed bearings, particularly for marine ships,

in flood proof, shockproof as well as non-magnetic

design. All thrust bearings undergo a test run

under nominal operating conditions on the RENK

test rig. Furthermore, RENK Han over Works

supplies disconnecting devices for high power

outputs to separate the propeller shaft from the

Diesel engine.

A drive shaft's mounting is optimised to improve

the efficiency and running smoothness of the

propulsion system as a whole. RENK supplies

shaft line components to satisfy the needs of the

shipping elite – from modern, high-performance

ferries, luxurious cruise ships and ultra-fast mega

yachts to even submarines – with low noise,

reliability and at highest efficiency.

RENK and the Blue Ribbon.

Record breaking requires sophisticated and

reliable engineering. Winning the Blue Ribbon

award for the fastest Atlantic crossing between

Europe and North America with a passenger like

ship demands power, efficiency and reliability in

equal measures. The following vessels, equipped

with RENK gear systems, won the coveted

trophy: the Italian monohull mega yacht Destriero

in 1992, the Danish catamaran ferry Cat Link V

in 1998, and another Danish catamaran ferry, the

Villum Clausen, in 2000. The latter took no more

than 24 hours to cover the 1063 nautical mile

route. We are suitably proud of these successes,

which serve as proof of RENK gear systems'

extraordinary power potential.
