Accepted Answer

BMA technology is a maritime equipment manufacturer specializing in {'name': 'Direct Propulsion', 'description': "Direct Propulsion With direct propulsion, the drive power of the engine is transmitted directly to the propeller via a rigid shaft that is guided outboard through the so-called stern tube. This type of propulsion is usually used in so-called “slow-steaming” diesel engines with speeds between 60 rmp and 250 rmp. The direction of rotation of the propeller can e.g. for reversing, can only be changed here by reversing the motor. The engine must then be stopped while driving ahead, reversed by moving the camshaft and restarted for reversing. Another possibility for changing the speed and direction of travel is to use a controllable pitch propeller: to change the ship's speed as well as for the prerequisite or reverse travel, the angle of attack (pitch) of the individual propeller blades is changed. The motor rotates at a constant speed. The shaft is usually flanged directly to the crankshaft of the engine by means of a flexible coupling. So-called medium-speed 4-stroke diesel engines with a speed range of up to 1200 rmp are primarily used on small-bit medium-sized cargo ships, passenger ships and in naval shipbuilding. High-speed runners with speeds> 2000 rmp can be found in inland shipping and in sport and leisure shipping. These speed ranges often require a gear reduction, also in connection with controllable pitch propellers."}, {'name': 'Electric Motors', 'description': 'Electric Motors Electric ship propulsion systems consist of a power generation system and an ordinary electric traction motor located in the aft ship. Today, the traction motor is sometimes even attached outside the hull and at the same time used as a “rudder system”. These are encapsulated 360 ° rotatable propulsion drives (azimuth systems / Azipod), which not only further improve the smoothness of running, but also give the ships particularly good maneuvering properties. Today they are used in particular in ferry and ro / ro shipping as well as on cruise ships. If the power generation plant is driven by steam turbine generators, it is called a turbo-electric drive, if diesel engines are used, your diesel-electric drive is used. The main advantages of these coupled drive systems are: - the good controllability (in connection with a controllable pitch propeller almost continuously adjustable) - depending on the power requirement, individual traction motors and generator sets can be switched on or off so that power is generated at the most favorable operating point - freedom of arrangement for the power generation system - freedom of automation - high travel comfort due to low noise and vibration pollution Disadvantages of the electric ship propulsion are, in particular, the poorer efficiency of the system and the higher investment costs.'}, {'name': 'Shaft Generator', 'description': "Shaft Generator The shaft generaltor is used to transfer the rotary motion / rotary power of the propelling engine to the propeller and to absorb the propeller thrust and its transfer to the hull. The shaft position can consist of one or more parallel drive trains (multi-propelled vessels). If the propelled engine is not located very far aft, the shaft system is usually a system divided into several segments. The shaft system includes the propeller shaft, also known as the tail shaft, which is guided through the stern tube, the line or drive shaft, the pressure wave, the shaft coupling, the bearings and the stern tube with the stern tube seal. The ship's propeller sits on the propeller shaft, which is guided in the stern tube by means of a water-lubricated slide bearing. At least on the inside of the ship, the stern tube is provided with a seal to prevent water from penetrating the ship's interior. The drive or line shaft, mounted on bearing blocks in plain, ball or roller bearings, is flanged to the pressure shaft. This is provided with a pressure flange and initiates the propeller advance into the ship's hull via the pressure bearing. The pressure wave in turn is connected to the crankshaft of the prime mover. In the case of ships with a continuous shaft, the thrust bearing can also be integrated in the main engine or in an optionally available gear; then there is no pressure bearing. For maintenance and assembly reasons, long shaft systems are made up of several partial shafts. Correct alignment of the shaft generator is important to ensure optimal operating conditions for ship propulsion. Improper alignment of the shaft generator can cause the ship to vibrate and damage the shaft bearings. In the case of very long shaft systems, a walk-in wave tunnel surrounds the wave system when crossing cargo holds or other ship spaces. Gearboxes are often part of the shaft system. These are used to reduce the engine speed, since speeds below 200 rpm, if possible even below 100 rpm, are aimed for a favorable drive efficiency in large shipping. In addition, the gearboxes often have additional drives for operating auxiliary machines such as generators or pumps. In complex drive systems, the gearboxes of the shaft system play a central role, since several motors and possibly turbines with very different speeds have to be switched to one or more shafts."}, {'name': 'Thrusters', 'description': None} with 2 brands.
