MPS - Marine Propulsipon Sliprings Manufactured by Cavotec Specimas

Specimas Marine Propulsion Sliprings Who we are Cavotec is a multi-national group of companies serving the following industries: mining and tunnelling, ports and maritime, steel and aluminium, energy and offshore, airports, general industry and automation. In the early 1960’s our main focus was the design and production of motorised cable reels primarily for manufacturers of tower cranes, harbour cranes and mining equipment. Today, Cavotec is connecting mobile equipment around the world in many diverse applications. The Cavotec Group consists of 7 manufacturing “Centres of Excellence”...

A revolutionary propulsion system Since the early 1950's, Asea Brown Boveri (ABB) has been supplying electrical propulsion and power plants for half of the world's icebreakers and many special purpose vessels built by Kvaerner Masa Yard (KMY) in Finland. AC/DC power plants and the Cyclo propulsion systems were introduced by ABB and KMY as a new technology early in 1983. New propulsion systems have been developed by other large companies like Schottel-Siemens from Germany and Alstom from France operating under different names as: Azipod (registred trade name of ABB), SSP Propulsor...

ABB azipod propulsion Installed on top of the ABB Azipod system, the MPS slipring system allows the pod and propeller to rotate the total 360 degrees. It’s function is to: • Transfer power (example 3600 Amps, 1,5 KV) from the diesel generators to the revolving outboard electrical motor and propeller through brushes and rings • Transfer auxiliary power, control signals and data signals or optical signals from the pod to the control Siemens-schottel SSP propulsion Installed on the top of the SiemensSchottel SSP System, the MPS slipring system allows the pod and propeller to rotate the total...

Specimas Cavotec's contribution to a revolutionary propulsion system In the early 90's, ABB Marine and Kvaerner Masa Yard of Finland approached Specimas for a R & D study concerning the power, data and hydraulic transmission for a revolutionary ship propulsion system using an outboard electrical motor instead of the traditional on line shaft inboard diesel powered propulsion. The 360 degrees manoeuvrability requires the installation of a slipring unit able to transmit up to 4000 Amps at 3 kV, data - control through optical fibers, or conventional rings and a special multi chanel swivel for...

Marine Propulsion Sliprings

The MPS sliprings are installed at the stern of the ship and according to the application can be single or twin, centrally located , or port and starboard side. Marine Propulsion Sliprings Designed , manufactured and tested to resist to forces of 5 G or more and strong vibrations, the MPS slipring is a vital component to the ship reliability.

In this photo of the main electrical control room, the “brain “ of the ship , we can see how the MPS slipring system is integrated in the propulsion system of the ship in order to insure 100% reliability on a ship carrying around 2500 passengers and crew. Marine Propulsion Sliprings
