Its task is to make sure that the electrical system is safe and efficient. If the power consumption is larger than the power production capacity, load shedding is used to avoid blackout. Other features could be to automatic start and stop consumers (e.g., diesel generators) as the load varies. [1]
Shore power or shore supply is the provision of shoreside electrical power to a ship at berth while its main and auxiliary engines are shut down. [1] While the term denotes shore as opposed to off-shore, it is sometimes applied to aircraft or land-based vehicles (such as campers, heavy trucks with sleeping compartments and tour buses), which may plug into grid power when parked for idle reduction.
This was enacted to make modern Electrical Engineers competent to understand the more complex and sophisticated electrical systems that are emerging. [ 7 ] On larger vessels such as cruise ships or specialized offshore DP vessels, [ 4 ] Electro-Technical Officers can have ranks within their profession, such position names include, lead ETO ...
The reduced weight and footprint of the installed electrical equipment will vary depending on the ship type and application. One comparison using the DC distribution system instead of the traditional AC system for a Platform Supply Vessel (PSV), reduced the weight of the electrical system components from 115,520 kilograms (254,680 lb) to 85,360 ...
Marine construction is the process of building structures in or adjacent to large bodies of water, usually the sea. These structures can be built for a variety of purposes, including transportation, energy production, and recreation. Marine construction can involve the use of a variety of building materials, predominantly steel and concrete ...
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
Cold ironing mitigates harmful emissions from diesel engines by connecting a ship's load to a more environmentally friendly, shore-based source of electrical power. An alternative is to run auxiliary diesels either on gas (LNG or LPG) or extra low sulphur distillate fuels, however if noise pollution is a problem, then cold ironing becomes the ...
Graphs by hour of California's total electric load, the total load less solar and wind power (known as the duck curve) and solar power output. Data is for October 22, 2016, a day when the wind power output was low and steady throughout the day. In electrical engineering, a load profile is a graph of the variation in the electrical load versus ...
