Catalog excerpts

Transverse Thrusters ► 50 kW to 1650 kW ► All major classifications ► Unrivalled durable gears ► 4000 thrusters in operation ► High-performance FP propellers 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 frequency-controlled 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 given thrust range in kN results from the calculation using the column ‘Max kW’ and is based on optimised tunnel, inlet cone and fore shapes. The range is influenced by the respective installation design.

Technical features: The propeller is mounted with a tight oil press fit which allows rapid mounting and dismounting during shaft seal changes. 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. Jastram transverse thrusters are made from high-grade certified materials and are designed individually according to the given installation conditions. Classification certificates for any classification society...
