The world’s first electric ferry will be launched in the year 2015 in Norway by Siemens and Norwegian shipyard Fjellstrand. The vessel will take only 10 minutes to recharge.
Earth fault is considered very critical on board a ship. Some ships which operate at 440 V do not have any trip devices attached for a single earth fault. However when the operating voltage exceeds 3000V, it is mandatory to have a protection system which isolates when a machinery suffers an earth fault.
With increase in modern technology and automation in ship’s machinery and operations, electronic circuits like printed circuit board or PCB along with signal transducer and transmission system are popularly used onboard. Since these are very small and vital circuits they require proper location and precaution for their installation.
With the increase in demand for alternate propulsion systems that not only improve the overall efficiency of the ship but also reduce the carbon footprints, innovators in the shipping industry are leaving no stone unturned to find a solution to this grave problem. With all the options presently available at hand, electric propulsion system [...]
The shipping industry has come a long way as far as R & D for reducing costs of propulsion without increasing marine pollution is concerned. The conventional propulsion system of the ship is efficient but requires high operating costs and increases the marine pollution. Among all the prospective alternate power sources, electrical propulsion system is [...]
Huge ships and tankers pollute the marine ecosystem considerably. The pollution caused includes acid rain because of sulphur oxide and smog because of nitrous oxide. In order to make sure that the levels of these pollutants do not increase further, there has emerged the concept of cold ironing or alternate marine power.
Apart from their small size, all electrical and electronic equipment or circuit on boards on ship play a vital role in operation of ship’s system and machinery. Different equipment onboard vessel utilizes alternating current, direct current or both depending upon the nature of operation. Some of the Very important circuits and setups are run through [...]
