Heli-Union Brand Guidelines: A 1961 Paris Operator, State Maintenance & Sabena technics

An oil-industry operator from the start.

Héli-Union, also written Heli-Union without the accent, is one of the older French helicopter operators. French Wikipedia dates its air-transport work to 1961: carrying people and equipment for oil and gas exploration and production, including crew changes on offshore platforms. The French company register lists a Héli-Union Investissements created in Paris in 1961, a company that has since ceased.

French Wikipedia says the company was created by a Mr Roussel, then chairman and chief executive of the laboratories that bore the same name. It describes how the business grew in three directions: air transport from 1961, helicopter maintenance in France and abroad, together with technical and logistics support for other operators, from 1985, and the training of helicopter pilots, with or without experience, from 2002.

The register records the companies behind those activities. Héli-Union Training Center was created in 2002 at Champniers, the commune of Angoulême’s airport, and an industrial company, Héli-Union Industrie, was created in 1986 at Châteaufort. Both are listed as active in 2026.

For much of its later history Héli-Union belonged to the Compagnie Nationale de Navigation (CNN), a French shipping group whose other subsidiaries include the Compagnie maritime nantaise and the Société d’armement de l’Ouest, according to French Wikipedia. Mer et Marine described Héli-Union as a CNN subsidiary in 2012, and Le Journal de l’Aviation named Patrick Molis, also listed by French Wikipedia among CNN’s leaders, as Héli-Union’s chairman and chief executive in 2022.

Offshore fleets and state contracts.

By the early 2020s Héli-Union flew a mixed civil fleet. Le Journal de l’Aviation reported in December 2020 that the operator had about forty helicopters, around twenty of them from Airbus Helicopters, among them Dauphins, the H145 family and the H225, and that it had ordered two Airbus H160s. In September 2022 the same publication listed types including the EC225, AW139, AS365 N3, S-76C++ and H145 D3, flown through subsidiaries around the world.

Engine support was contracted for the long term. In November 2021 Le Journal de l’Aviation reported a five-year extension, to 2029, of a Pratt & Whitney Canada fleet management programme covering 18 PT6C-67C engines on Héli-Union’s Leonardo AW139s, first signed in 2014. The same month it reported that Héli-Union Gabon had received its air operator’s certificate and operating licence, based at Port-Gentil for onshore freight and passenger flights with a Dauphin AS365 N3.

Maintenance and training made Héli-Union a supplier to the French state. In June 2012, Mer et Marine reported, Eurocopter and Héli-Union opened a Dauphin AS365 N3/N3+ flight simulator, built with Thales, at Héli-Union’s training centre in Angoulême, qualified as a level B full flight simulator and owned by Héli-Union Training Center. In November 2019 Air & Cosmos reported that Airbus Helicopters and Héli-Union had been notified of a global support contract for the Cougar, Caracal and EC225 helicopters of the French Army and Air Force, tied to France’s 2019–2025 military programming law.

Le Journal de l’Aviation wrote in 2022 that Héli-Union held a FRA 145 maintenance approval and carried out work for the French state on Dauphin, Panther, Cougar, Super Puma and Caracal helicopters.

Offshore helicopter operators.

Offshore helicopter operators sell a narrow service: moving crews and cargo between airports and installations at sea, and standing by for search and rescue. Their websites tend to follow the same plan. Bristow divides its work into offshore energy services, search and rescue, government services and advanced air mobility; CHC lists offshore transportation, search and rescue, emergency medical services, utility work and maintenance.

Colour carries much of the identity. Liveries vary from operator to operator, from navy to red and orange, and some choices carry history: when CHC came out of Chapter 11 in 2017 it changed its company colours to the orange of Okanagan Helicopters, one of its founding companies, Vertical reported. The photographs the companies publish tend to show helicopters over open sea or on helidecks, next to fleet pages arranged by type, from the Sikorsky S-92 to the Airbus H175 and the Leonardo AW139 and AW189.

Base maps are another constant. In the North Sea they run from Aberdeen, Norwich and Humberside to Stavanger and Den Helder; other networks reach the Gulf of Mexico, Brazil’s Santos Basin, West Africa, Australia and Southeast Asia. Contract news fills the press pages: crew-change deals with energy companies, coastguard search-and-rescue contracts such as those in the United Kingdom, Ireland and the Netherlands, and maintenance work, which CHC sells under its Heli-One name.

Many of these operators have also been reshaped by restructurings and mergers. CHC filed for Chapter 11 in 2016, Bristow’s US entities followed in 2019, and Bristow merged with Era Group in 2020, so investor pages, quarterly results and ticker symbols sit alongside the helicopters. This guide sets out what can be checked about each operator — who founded it, who owns it and where it flies — and marks clearly what rests only on the company’s own word.

A new owner in 2022.

In September 2022 Héli-Union changed hands. Le Journal de l’Aviation reported on 30 September that the French maintenance group Sabena technics, backed by its shareholders Sagard, Bpifrance and Towerbrook, had announced the purchase of 100 percent of the Héli-Union group. Le Monde du Droit reported in October 2022 on the lawyers who advised on the acquisition and put Héli-Union’s staff at 350, and Sabena technics’ own history lists 2022 as the year it acquired the Héli-Union group and created a helicopter division.

Under the new owner, Le Journal de l’Aviation reported, Patrick Molis was to join the Sabena technics board and Jonathan Cosson was to run Héli-Union, with the aim of bringing Sabena technics’ own helicopter work into it. Sabena technics said the combined group would support half of France’s military helicopter fleet and gain sites in six more countries. Aerobuzz noted that the purchase followed Sabena technics’ takeover of Aeromecanic in 2020.

The name stayed in use after the sale. In October 2023 Mer et Marine described Héli-Union as a subsidiary of Sabena technics, which it said had bought the company a year earlier, and reported that a new Airbus H160, leased from Héli-Union for up to eight years, was about to be delivered for the French customs service in the Antilles. Héli-Union had won that contract in 2022, through the defence ministry’s aeronautical maintenance directorate, and it was confirmed in February 2023, the magazine said. The French company register still lists Héli-Union Training Center at Champniers as active, with a Sabena technics company as its president.

For a design guide, Héli-Union shows how an operator’s name can outlast a change of owner when its flying, maintenance and training carry on. Compare Airbus, whose helicopters make up much of its fleet, and NHV, another European helicopter operator. For this guide we use a marine blue, a slate grey and a pale sky with a sans, an unofficial interpretation; no product or logo is reproduced.
