On 28 December 2016 a Sikorsky S-92 helicopter (registration G-WNSR, serial number 920250) operated by CHC Helicopter experienced "unexpected control responses" whilst in mid-air on a routine shuttle flight between two oil installations in the North Sea. The pilots conducted an emergency landing on the West Franklin platform. The helicopter is reported to have spun on the helideck during the landing, damaging the helicopter wheels and rotor blades. The helideck also sustained damage during the emergency landing.

|
For the interception of fast speedboats (which after all are faster than the OPV), two so-called FRISCs (small vessels) are transported, which reach a speed of more than 40 knots. One of them is carried in davits, the other in a small dock (a slipway) on the stern (below the helideck). The ships will receive a Combat Management System (CMS) from CAMS-Force Vision.

Project 21900 icebreakers are long overall and have a moulded beam of . Fully laden, the icebreakers draw of water. While Project 21900M icebreakers are slightly longer at , they have the same beam, design draught and displacement. The general layout of both designs is somewhat similar with the largest external difference being the helideck: Project 21900 icebreakers have a slightly smaller landing area located behind the superstructure while in Project 21900M and 21900M2 icebreakers the helideck has been moved to the forecastle and increased in size. Both Project 21900 and 21900M icebreakers have a fully integrated diesel-electric propulsion system with four main diesel generators supplying power for both main propulsion as well as the ship's service loads while underway. In the first two vessels, the main power plant consists of two 9-cylinder Wärtsilä 9L32 and two 12-cylinder Wärtsilä 12V32 medium-speed diesel engines. In the three following vessels, all four main engines are identical 12-cylinder Wärtsilä 12V32E units rated at each. In addition, all icebreakers have two Wärtsilä 4L20 auxiliary diesel generators for use when the vessel is at port.

There are berths for 18 crew members and 16 supernumeraries; 34 in total. When operating as a supply vessel, Vladimir Ignatyuk can carry 100 tonnes of bulk cargo in silos, 800 tonnes of deck cargo on the aft deck, and 200 tonnes of drilling water. The towing gear consists of an 80-ton winch holding of wire and a separate 200-ton double-drum anchor-handling winch. Although initially built without one, Vladimir Ignatyuk was later fitted with a helideck above the foredeck.

The heavy military ramp was replaced with a new stern door and the helideck was removed. Following this, she arrived in Douglas on 11 May 2009. An open day took place at each of the company's ports and at a renaming ceremony, she was renamed after Manannán mac Lir, the Celtic god of the Irish sea. Manannan made her maiden service voyage with the Steam Packet Company on Friday 22 May 2009 on the 07:30 sailing from Douglas to Liverpool.

The Smalls Lighthouse from several miles away The first stone of the new lighthouse tower was laid on 26 June 1857, Trinity House having bought out the previous leaseholders in 1836. The tower was completed in 1861. In 1978 a helideck was erected above the lantern and in 1987 the lighthouse was automated. It is the first wind- and Solar-powered lighthouse in the U.K. Although it has only a 35-watt bulb, with the aid of lenses, this can be seen up to away.

The influence of the various Civil Aviation Authorities around the world has had a huge effect on the efficiency and safety of working in this position. The safety of all personnel traveling to a ship or offshore location is in the hands of these specialists, whilst moving to and from the helicopter. The HLO commands a team, which again, is usually made up of members of the ship or installation crew, known as HDA's (Helideck Assistants). The assistants themselves are also trained in passenger and freight handling, helicopter safety and fire and rescue.

It is served by a 35-ton main crane and three 10-ton general cargo cranes, all of which can also be used to lower scientific equipment and vehicles on ice. When heavy loads are being lifted, a heeling tank is used to balance the vessel. S. A. Agulhas II is the first ship of her kind to be allowed to carry both passengers and fuel, such as polar diesel, Jet A helicopter fuel and petrol, as cargo. S. A. Agulhas II has a hangar and helideck capable of serving two Atlas Oryx or Aérospatiale SA 330 Puma helicopters.

In April 2015, Arctia Shipping announced that Otso had been chartered to an unnamed client to support seismic surveys in the Arctic for two years with an option of two additional years. The vessel was upgraded for service in the northern latitudes by increasing her ice strengthening, previously adequate only for icebreaking in the Baltic Sea, to Polar Class 4 (PC 4) which is intended for vessels operating year-round in thick first-year ice which may include old ice inclusions. Furthermore, a anti-rolling tank was installed to improve her open water characteristics. Other additions included lifeboats to allow unrestricted worldwide service as well as a new helideck.

Work to safely remove the West Atlas drilling rig from the Montara well head platform (WHP) in the Timor Sea started in August 2010. The offshore construction vessel Jascon 25 equipped with an 800-tonne crane was mobilised for the salvage operations. This work was expected to take about three months and involve cleaning and removal of debris from the rig as well as the cantilever drill floor which was left extended over the WHP helideck after the fire in November 2009. After the debris removal work was completed, this was followed by the jacking down of the West Atlas rig to be towed to Singapore.

While Project 21900M vessels were still sometimes referred to as "16-megawatt icebreakers", their propulsion power was increased to 18 megawatts. Externally, the most apparent difference is the helideck which has been moved to the foredeck and enlarged for the bigger Mil Mi-8 helicopter. The construction of the first Project 21900M icebreaker began at Vyborg Shipyard on 20 August 2012, a month ahead of schedule, and the keel laying ceremony was held on 17 October. Initially, the completed hull blocks were stored in the open while the shipyard was finalizing the construction of a semi-submersible barge Atlant that would be used for hull assembly and launching of the new icebreakers.

Although the 6,000-ton Ilya Muromets is the largest icebreaker ever built for the Russian Navy, she is somewhat smaller than the civilian icebreakers operated by Atomflot, Rosmorport and Sovcomflot. In terms of size and general layout, the vessel is comparable to the civilian Project MPSV06 multi-purpose salvage vessels with a working deck aft, deckhouse amidships and a helideck rated for Kamov Ka-27 helicopter. Like her civilian counterparts, Ilya Muromets is also equipped with a towing winch and stern notch for escorting other ships in ice conditions. She is served by a crew of 32 but can carry up to 50 marines in full combat gear.Russian Navy’s brand new icebreaker Ilya Muromets floats off (PHOTOS, VIDEO). Russia Today, 10 June 2016.

The Helicopter Landing Officer, also known as HLO is the most vital part of the operating team for offshore helidecks. (A helideck is a purpose built helicopter landing area, usually on a ship or offshore oil/gas installation.) Over the years the offshore oil exploration and production business has relied upon helicopters as the main method of transferring personnel to and from their workplace. Traditionally, and legally these days, the appointment of an HLO is the responsibility of the ship or installation operator. In the early days of offshore helicopter work, the basic requirements of safety were met by persons who would have a primary task (Deck supervisor, Crane supervisor etc.) and would take responsibility for the helicopter crew change as a secondary task.

In the aft, there is a helideck and a hangar for single Kamov Ka-32 helicopter. Being an escort icebreaker, Taymyr is equipped with a standard towing winch and a stern notch for close towing in difficult conditions. Taymyr is classified by the Russian Maritime Register of Shipping with the Russian ice class LL2, which means that she is intended for icebreaking operations on Arctic coastal routes in level ice up to thick during winter and spring.. The shallow draught of the icebreaker allows it to operate in rivers, estuaries and other locations where the water is not deep enough for bigger Arktika-class icebreakers and the ice conditions are so severe that refueling of diesel-powered icebreakers would be difficult, even impossible. When the Taymyr-class icebreakers were designed, considerable effort was put into improving the safety of these nuclear-powered ships.
