What products does SEAM AS manufacture?

Accepted Answer

SEAM AS is a maritime equipment manufacturer specializing in {'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': 'Hybrid Drives', 'description': 'Hybrid Drives The reverse process of electrolysis takes place in the fuel cell. The fuel cell reverses this process and generates electrical energy from the reaction of oxygen and hydrogen to form water. The actual cell consists of two electrodes in an electrolyte (e.g. potassium hydroxide). In the two electrodes (anode and cathode) the so-called reactants hydrogen (on the anode side) and oxygen (on the cathode side) are continuously fed from storage tanks in the boat as long as the process is running. Depending on the type of fuel cell, methane, methanol or glucose solutions can also be used as fuel. On the cathode side, hydrogen peroxide or potassium thiocyanate can also be used as the oxidizing agent. The two electrodes of a cell consist of a substance with catalytic properties, e.g. Platinum. This means that this substance favors the reactions to take place. In the electrolyte, the positively charged hydrogen ions migrate to the cathode and combine with the oxygen to form water. A positive potential is created at the cathode. The electron balance takes place via the circuit via a connected consumer under workload Long-term shipbuilding research already deals intensively with the topic of fuel cells. Companies in the shipbuilding industry and universities work in the “National Innovation Program for Hydrogen and Fuel Cell Technology” (NIP) on the fuel and drive technology of tomorrow. With the joint project “e4ships - fuel cells in maritime use”, the emission-free ship operation of the future is being prepared on the one hand, but practical, modular solutions for on-board power supply and port operation of the present are also being developed. Building on the success of the demo projects “PA-X-ell” (passenger ships) and “SchiBZ” (cargo ships), hybrid drives, consisting of a gas combustion engine, fuel cell, solar cells and energy storage system, are now being developed for river cruise ships in the new “Rivercell” project.'}, {'name': 'Hydrogen Propulsion', 'description': 'Hydrogen Propulsion Hydrogen reacts both in fuel cells and in direct combustion with oxygen to form pure water, releasing high levels of usable energy without releasing carbon dioxide (CO2), as is the case with fossil fuels. Hydrogen - bound in water - is theoretically available in unlimited quantities and should be produced with the help of regenerative energy (electrolysis). However, the storage of the fuel is a major problem. As a gas, hydrogen is extremely volatile and has only a very low density. In order to be able to use hydrogen sensibly as a fuel on board a vehicle, it is necessary to achieve a high energy density in the smallest possible space (high storage density) in order not only to have sufficient cargo space capacity (volume / load capacity) for commercial use, but also ensure an adequate range of the vehicle. To do this, however, the hydrogen must be liquefied using additional energy and cooled to -253 ° C. This makes it clear that hydrogen tanks require complex insulation in order to minimize unwanted evaporation. For this purpose, vacuum-insulated pressure tanks are used, which are constructed according to the concept of a thermos flask. But even then the hydrogen needs 4 - 5 times the volume compared to mineral oil. Even if there are engine types with the possibility of direct combustion of hydrogen, the development of fuel cells is currently in the foreground. With this technology it is possible to convert the energy generated by a chemical reaction directly into electrical energy. Compared to combustion engines, fuel cells achieve an above-average high degree of efficiency. However, it will be some time before such fuel cells are used on board merchant ships, since the effort required for this technology is very high, especially when it comes to making high outputs of up to 80,000 kW available. But there are already ships that use and test hydrogen propulsion.'}. View full product details on TrustedDocks.
