Performance Reliability Simplicity

DOEN 100G
Product Introduction:
Our aim was to provide boat builders and boat operators alike with a waterjet

DJ100G
option that has been specifically designed to optimally match with today’s
high-speed diesels. A waterjet that delivers superior all round performance
and better load carrying capability. To best achieve this, several key design
criteria had to be met.
 Larger capacity axial flow pump
 Dedicated impeller technology
 Correct engine to jet matching
The new Doen DJ100G delivers all of these criteria within a compact and
cost effective package.

The Doen DJ100G waterjet utilises a large diameter ten-inch (254mm) pump
incorporating our latest impeller technology to provide higher thrust with superior
cavitation resistance. This results in improved speed, better load carrying,
enhanced range and fuel efficiency and unsurpassed cavitation resistant
performance.

The integration of a gearbox allows the Doen DJ100G to be precisely and

simply matched with engines to simultaneously ensure proper engine loading
and optimal impeller speeds, for best efficiencies and highest cavitation
resistance. Stock ratios are available to suit today’s high-speed diesels with
power outputs up to 300hp continuous and 400hp sprint (by application).

This waterjet pump is built using a tough,

heavy-duty construction comprising only
stainless steel and aluminium with an anode
anti-corrosion system. The simplicity of the
design makes the Doen DJ100G very easy to
service and maintain.

Case Study 119: Thursday Island Reef Pilot

SPECIFICATIONS

Waterjets: DJ110 (Twin)

Engines: Cummins 6CTA 8.3M
430hp @ 2600 rpm
Gearboxes: N/A direct couple
Vessel: 12.6m L.O.A
10.2m L.W.L.
9.2 tonnes
Performance: 35 knots

Launched in 1998, this pilot vessel is still going strong on her second set of engines

Launched in 1998 this aluminium RHIB 12.6m pilot vessel, propelled by twin DOEN DJ110
waterjets, operates in the warm tropical waters around Thursday Island off the far North Australian
coast. During this time it has logged more than 15,000 hours and has provided exceptional reliability
at all times.

Originally launched with Volvo 420hp diesels these engines were subsequently replaced by twin
Cummins 6CTA 8.3M 430hp diesels after many years of hard work. The current engines are direct
coupled to the DOEN DJ110 11.0-inch (279.5mm) diameter high volume axial flow impellers. The
waterjet units provides excellent cruise capability and fuel economy with un-compromised top speed
under arduous sea and varying load conditions; all of which are extremely important for a pilot
vessel.

The DOEN balanced steering nozzle gives fast, precise response with minimal input force. This is
simply controlled using a conventional manual hydraulic steering system with inboard cylinder ,
which is mechanically connected to the waterjets inboard steering tiller. This provides the vessel with
exceptional easy control at all speeds and especially when maneuvering alongside a moving ship for
pilot transfer. both high and low speeds. A simple mechanical tie bar is used to connect the
waterjets providing synchronized steering at all times.

The DJ110 waterjets are fitted with DOEN’s Jogstick Reverse System (JRS); an electro hydraulic
control system that provides non-follow up jog lever control of the waterjets reverse buckets. An
analogue indicator is used to show the reverse bucket position. This robust, simple and cost
effective system remains very popular with operators in remote and rugged use applications.

Third in a series of hard working thrill ride boats from Australia’s Calibre Marine
The brief for this boat was full-throttle hard-turning operation, 7 days a week all year round, up to 45
knot performance with 12 passengers, Captain and a full load of fuel. This boat gets put through a
series of full throttle, hard turning, spin and crash stop maneuvers during every one of the many 20
minute rides it takes passengers on every day.
A pair of Doen DJ120 jets, coupled via ZF transmissions, to Yanmar 337hp engines are ideally
suited to the task. The 310mm diameter, high volume axial flow impellers, providing the immediate
high thrust that is needed even under extreme acceleration, white water and hard cornering
conditions.
The DOEN balanced steering nozzle gives fast, precise response with minimal input force allowing
simple light duty steering system to be used. An electric power steering system is used to provide
small turn ratio’s with little effort. The heart of the package is the microprocessor controlled pump
unit which senses loads and instantly delivers flow and pressure when loads are applied, reverting to
minimum current draw when no load is sensed. This provides the vessel with precise control for the
quick and aggressive maneuvers that this boat has to perform many times in daily operations

The DJ120 waterjets are fitted with DOEN’s Rotary Servo Control (RSC), which is an proportional
hydraulic control system providing simple and exact follow up control of the waterjets reverse
buckets, by conventional lever. This system has fully integrated hydraulics with in built cooling;

RUSSIAN COAST GUARD – 16.7m Multipurpose Fast Craft

This 16.7m fiberglass vessel has been built for the Russian Coast Guard. It is powered by twin MAN
R6-800 diesel engines direct coupled to DOEN DJ140HP waterjets. Designed for high-speed patrol
and sea rescue activities this vessel has fully enclosed cabin with forward accommodation and
sleeping for crew.

The DJ140HP is a 380mm diameter single stage compact high performance waterjet that uses
Doen’s latest impeller technology that delivers mixed flow type, high-speed performance, within an
axial build. This approach combines the key benefits of excellent high-speed efficiency with superior
cavitation margins and efficiency at lower speeds and cruise conditions. This waterjet model
incorporates many innovative features that enhance its application into high-speed craft such as the
lightweight fabricated intake tunnel, providing scope for design customization and efficiency
optimisation

Each waterjet has its own fully integrated hydraulic system to operate the waterjet reverse and
steering functions. Jet driven hydraulic pumps supply fluid power to the jet mounted hydraulic valve
bank. All of the hydraulic equipment including reverse cylinders, steering cylinders and hydraulic
lines are mounted inboard.

The vessel is fitted with Doen’s ECS-100 Control System with eDOCK joystick control. This
electronic control system provides primary control of engine throttle and the waterjet steering and
reverse functions. A single joystick lever provides combined bucket and throttle control with steering
by conventional helm wheel in cruise mode and in docking mode this same joystick provides a full
vectored control of the waterjets steering, reverse and engine throttle function for precise and
intuitive low speed maneuvering control.

A high speed Aluminium monohull operating in the Red Sea off Saudi Arabia
DOEN DJ170HP waterjets propels this aluminium 15.1m monohull designed and built to BV Class
Rules by NGV Tech in Malaysia. This vessel is one of five built for use by a Saudi Arabian Security
Company that provides harbour patrol and surveillance activities for oil company asset protection.
Power is provided by twin CAT 747kW diesel engines, which are coupled to the DOEN waterjets
through ZF marine transmissions. A reduction ratio is used to optimise the waterjet impeller selection
and the gearbox also provides the vessel with disengagement and a back flushing capability.
The DOEN 17.0-inch (432mm) diameter high volume axial flow impellers provide excellent cruise
capability allowing long range patrol at reduced fuel consumption whilst delivering an un-
compromised top speed of 45 knots.
The DOEN balanced steering nozzle gives fast and precise response. These are controlled using a
conventional helm power assisted hydraulic steering system. Inboard cylinders are mechanically
connected to the waterjets inboard steering tiller. This provides the vessel with exceptional easy
control at all speeds and especially when maneuvering around rigs and alongside other vessels. A
simple mechanical tie bar is used to connect the waterjets providing synchronized steering at all
times.
The DJ170HP waterjets are fitted with an electronic control system. This fully electronic control
provides single lever function, which combines control of the engine throttle and waterjet reverse
bucket into one simple and reliable system. The reverse function provides full follow up control of
the reverse bucket by way of the jet mounted hydraulic system incorporating a proportional solenoid
valve. Control of the marine transmission is by way of separate, simple to use, touch pad.

Five Nigel Gee 18.5m Water Taxis for service in Nigeria

Estaleiros Navais de Peniche yard on Portugal’s Atlantic Coast built five of these BMT Nigel Gee
designed 18.5m catamarans ordered for a Rivers State Water Taxi Service in Nigeria to carry up to
70 passengers. The vessels are used to provide transport to remote riverine regions where low draft
was required. In these regions there is extensive oil and gas industry but little or poorly developed
road infrastructure exists to provide access.
Power is provided by twin CAT 533kW diesel engines, which are coupled to the DOEN waterjets
through ZF marine transmissions. A reduction ratio is used to optimise the waterjet impeller selection
and the gearbox also provides the vessel with disengagement and a back flushing capability.
The DOEN 17.0-inch (432mm) diameter high volume axial flow impellers provide highly efficient
propulsion that delivers excellent cruise performance and extended range in this application under
all load conditions.
The DOEN balanced steering nozzles are controlled using a conventional helm power assisted
hydraulic steering system. Inboard cylinders are mechanically connected to the waterjets inboard
steering tiller. This provides the vessel with simple and easy control at all speeds and especially
when docking. A simple mechanical tie bar is used to connect the waterjets providing synchronized
steering at all times.
The DJ170HP waterjets are fitted with DOEN’s Rotary Servo Control (RSC), which is a proportional
hydraulic control system providing simple and exact follow up control of the waterjets reverse
buckets, by conventional lever. This system has fully integrated hydraulics with in built cooling;
bulkhead mounted steering and reverse cylinders and all connections inboard and protected from
corrosion. Conventional control levers using push pull cables operate this system.
