Ice house

energy

An Ice house, or icehouse, is a building used to store ice throughout the year, commonly used prior to the invention of the refrigerator. Some were underground chambers, usually man-made, close to natural sources of winter ice such as freshwater lakes, but many were buildings with various types of insulation.

Ice storage air conditioning

energy

Ice storage air conditioning is the process of using ice for thermal energy storage.

Ice strengthening

marine

Ships intended for navigation in ice conditions are specially reinforced. Ice strengthening concerns the side shell structure, stem, stern frame steering gear, propeller and shafting.

Ice thickness

marine

Temperature in the Baltic, typically –15°C. Temperature in the Artic, down to –40°C.

Icebreaker

marine

A vessel used for keeping a navigable passage open through ice. Icebreakers are grouped in ice classes according to the thickness of the ice to be broken.

Icebreaker/offshore vessel BOTNICA

marine

Finland is entirely dependent on icebreakers to keep its trade routes open in winter. Icebreakers are normally in operation from mid November until the end of May.

Icebreaking PSV VITUS BERING

marine

VITUS BERING is the icebreaking platform supply and emergency rescue vessel built by Arctech shipyard at Helsinki.

ICEPOD

marine

An azimuthing, pulling thruster developed by Wärtsilä and designed to 1A Super Ice Class or higher standards.

Icing

marine

Icing caused by freezing sea spray or snow forming a layer of ice on deck and superstructure when operating in low temperatures may have major impact on the safety and general operation of a vessel.

Icon

marine

I-core panels

marine

Laser-welded sandwich panels, developed by Macor Neptun and Meyer Werft, used as a deck construction material.

Ideal gas

energy

An ideal gas is a theoretical gas composed of many randomly moving point particles that are not subject to interparticle interactions.

Ideal gas law

energy

The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas.

IEC 61400

energy

IEC 61400 is an International Standard published by the International Electrotechnical Commission regarding wind turbines.
