The word "helideck" refers to a landing area for helicopters on a ship or a heliport. Its spelling follows a combination of the Greek root "helio" for sun and the English word "deck". The word is pronounced as [ˈhɛlɪdɛk], with the stress on the first syllable. The first two letters "he" are pronounced as in "helicopter", while the next three letters "lid" are pronounced as in "lid". The last syllable "deck" is pronounced as in "deck of cards".
A helideck is a designated area on a platform, vessel, or structure specifically designed and constructed to accommodate the landing and takeoff of helicopters. It serves as a safe and secure landing platform for helicopter operations and allows for efficient transportation, transfer, and support services.
Typically located on offshore platforms, buildings, ships, or other elevated structures, a helideck consists of a flat or slightly inclined surface with designated markings, lighting, and safety equipment to ensure successful and safe helicopter operations. The surface is often made of non-slip materials such as steel, concrete, or composite materials to improve traction.
Helidecks are built in compliance with strict regulations and standards that govern their size, construction, and safety requirements. This includes factors such as size limitations, wind limitations, lighting specifications, firefighting equipment, and access to emergency systems. Fire suppression systems, like foam monitors or water sprays, are often installed to quickly extinguish any potential fires during helicopter operations.
To ensure the safety of personnel and equipment, helidecks are subject to regular inspections and maintenance checks to uphold their structural integrity and operational readiness. Strict operating protocols and procedures are in place to guide helicopter pilots, crew members, and ground personnel during helicopter landings, takeoffs, and other related activities.
Overall, helidecks are essential facilities that enable efficient air transportation, emergency response, and logistical support in diverse sectors, including offshore oil and gas industries, search and rescue operations, military deployments, and medical evacuations.
The word "helideck" is derived from two main components: "heli-" and "-deck".
1. "Heli-" is derived from the Greek word "helikos", meaning "spiral" or "twisted", which originated from the word "helix". In modern usage, "heli-" is associated with "helicopter" or "helical", usually denoting something related to or involving helicopters.
2. "-Deck" is derived from the Old English word "dæc", meaning "covering" or "that which covers". It has been historically used to reference a platform or level surface, often aboard a ship or aircraft, where people can stand or walk.
Combining these two elements, "helideck" refers to a specially designed platform or area, on a ship or offshore structure, that serves as a landing and takeoff site for helicopters.
