Manoeuvring Competence 1889 Carl Jastram, along with Nikolaus Otto and Rudolf Diesel was one of the pioneers in the development of combustion engines. After founding the first engine manufacturing company in Hamburg Jastram began supplying the growing port industry with hundreds of diesel engines, pumps and small barges.

Since 1889

1928 Hans Jastram continued the work of his father and started developing and producing bow thrusters in the fifties. With his genius and numerous technical publications he established the basis for the enduring success of Jastram transverse thrusters. 1965 Peter and Claus Jastram founded the ‘Jastram Forschung’ research and development department to provide a scientific background for new products. A range of active and passive manoeuvring systems such as rudder propellers, rotor rudders, flap rudders, azimuth grid thrusters and noise reduction systems extended Jastram’s capabilities. 2003 With Nils Jastram at its head, Jastram GmbH & Co KG is now in its fourth generation of family ownership. The company continuously strives to improve the product range, quality and service to maintain and expand it’s good reputation in the international maritime industry.

The stainless steel ring in the propeller tip region protects the tunnel against cavitation damage. The oil lubrication system with oil level sensor (to be installed by the shipyard above waterline) protects the seals against water ingress. Galvanic cathodic protection (CP) is calculated and installed to protect the system for up to 5 years. Options: Impressed current cathodic protection (ICCP) instead of anodes for longer life and reduced resistance in the tunnel.

Jastram have been developing and producing transverse thrusters since 1950. Reliable gears, worldwide service, direct contact to our service department and detailed archived data for each delivered system are well accepted by the maritime industry and international shipping companies. Jastram are specialised in fixed pitch propeller (FPP) thrusters which require minimal servicing due to their solidity and durability. To improve performance the propeller design is continuously modified according to the latest developments. With electric drive systems ranging from the low-cost 3-step control for onshore manoeuvring to the frequencycontrolled drive for offshore dynamic positioning Jastram offer transverse thrusters for a wide variety of vessel types. The following table of Jastram thruster types indicates the maximum speed and power based on a 50Hz / 60Hz power supply and the German Lloyd type approval. ‘Max kW’ may differ for special applications and requirements of other classification societies.

The Jastram azimuth grid thruster is capable of providing highly accurate dynamic positioning, responsive steering and emergency propulsion.

Mounted flush to the bottom of the vessel, it has no protruding parts which could be damaged in shallow water. A removable grid protects the horizontally mounted propeller. Smaller parts and sand are washed through the large-volume housing. A special propeller generates effective thrust with a high volume at a low pressure.

With the solid Jastram thruster gear, the water is pumped through the 360° rotating steering grid.

Turning the grid by up to 180° in 8 seconds, the thruster provides immediate thrust in all directions. The prime mover can be moved by 180° around the propeller according to the given installation conditions in the hull structure.

The given thrust range is based on experience as well as calculations using the column ‘Max kW’ and is about 70% of the thrust of transverse thrusters. ‘Max kW’ may differ for requirements of classification societies. Type

Drawing on experience in thruster drive and control systems since 1950 Jastram offer a wide range of applications: 3-step drive systems with resistor units and slip ring motors have been the most popular drives over the last few years. Dynamic drive, a multistep drive system with resistor unit, slip ring motor and reduced starting current, is the cost-competitive alternative to controllable pitch propeller (CPP) thrusters with the advantages of the robust fixed pitch propeller (FPP).

3-step master and slave panels with customised colours. New design with two additional spaces for lamps and buttons for special functions such as restricted power management.

Frequency-controlled (FC) drives accommodate the increasing demand for stepless control. Interfaces to joysticks and dynamic positioning systems as well as any other customised application can be realised by Jastram. Control systems including operator panels for hydraulic and diesel engines as well as other drive systems are designed and interfaced in close cooperation with the supplier of the prime mover.

Operator panels for dynamic and frequency-controlled (FC) drives.

Operator panels for bridges, wings, afts, flybridges and portable stations are available in standard or customised designs. The alarm system displays alarms and faults on the operator panels and switch cabinet. Interfaces to any alarm monitoring system (AMS) can be achieved. Technical features:

Noise-reduced manoeuvring systems from Jastram meet the international mega-yacht industry’s demand for the ultimate comfort. Active and passive low-noise thrusters from Jastram offer sophisticated technologies for silent manoeuvring in ports and during offshore dynamic positioning.

Active noise reduction In the mid-fifties, when the first transverse thrusters were being delivered, Jastram were already working on technologies for noise reduction. Jastram applied for their first patent for a method for noise reduction in 1964. Scientific research was performed by ‘Jastram Forschung’ in the eighties in an in-house test basin and on board several vessels. These experimental series and measurements established the basis for the calculation of the Jastram noise reduction systems.

dB (A)

110

Cavitation is one of the main sources of noise in tunnel thrusters and can be effectively reduced to 15dB(A) through active noise reduction. The mixture of air and water reduces the noise both inside and outside the vessel.

100

90

Passive noise reduction Structure-borne noise and ambient noise generated by mechanical vibrations can be diminished only by resiliently mounted gear, propeller and motor.

80

The resilient mounts were developed with both full-pipe and half-pipe tunnels to meet the requirements of varying installations for all hull designs.

70

The combination of active and passive noise reduction offers optimised results and is being used worldwide in workboats, commercial vessels, cruisers and yachts.
