Liquid-dominated reservoirs (LDRs) are more common with temperatures greater than 200 °C (392 °F) and are found near young volcanoes surrounding the Pacific Ocean and in rift zones and hot spots.
Liquid-metal batteries are used for industrial power backup, special electric vehicles and for grid energy storage, to balance out intermittent renewable power sources such as solar panels and wind turbines. The electrode and electrolyte layers are heated until they are liquid and self-segregate due to density and immiscibility.
If the centerline plane of a ship is not vertical, as when there is more weight at one side than at the other, she is said to list, or to heel.
Lights visible from the deck showing that a ship is listing.
Lithification is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock.
A Li-ion battery is a type of rechargeable battery.
The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples, or with low magnification microscopy.
Lithostratigraphy is a sub-discipline of stratigraphy, the geological science associated with the study of strata or rock layers.
Live-line working, also known as hotline maintenance, is the maintenance of electrical equipment, often operating at high voltage, while the equipment is energised.
Vessels designed to carry live animals. Ventilation and drain systems are of crucial concern. They are usually converted second-hand ships used to carry live sheep from Australia to the Gulf.
LNG has three major characteristics as a seaborne trade cargo: the super low temperature (-160°C), a low specific gravity (0.43 to 0.50) and flammability.
GDF SUEZ NEPTUNE was built by Samsung Heavy Industries (SHI), Korea, and delivered to her operator Hoeg LNG, on 30th November 2009. The vessel has a transport capacity of some 145,000 m3 and a contract price of about $290M.
LNG carriers have, up to 2006, mainly been driven by steam turbines. The boil-off gas (BOG) from the LNG cargo has so far been used as fuel.
A new type of LNG tanker provided with re-gasification facilities. A tanker having loaded a LNG cargo in the conventional way regasifies the cargo on board and discharges the high-pressure gas at an offshore buoy or floating terminal.
A highly-sophisticated gas carrier with very specialized LNG cargo containment system built for transportation of natural gases in bulk. As it is usual with LNG tankers, the cargo is transported at a temperature of -160°C.
Built by Hyundai Heavy Industries in Ulsan, the BRITISH EMERALD is the LNG tanker with dual-fuel diesel-electric propulsion. At 155,000 cubic metres she is one of the largest LNG carriers to date.
Although steam turbine propulsion has served LNG tankers well for a couple of decades, this type of propulsion is relatively inefficient and expensive to operate.
A shipping terminal designed specifically to handle LNG ships the LNG product.
Load balancing, load matching, or daily peak demand reserve refers to the use of various techniques by electrical power stations to store excess electrical power during low demand periods for release as demand rises. The aim is for the power supply system to have a load factor of 1.
Used in electric power generation to illustrate the relationship between generating capacity requirements and capacity utilization. The demand data is ordered in descending order of magnitude
