The industry leader: applying decades of experience and insight in the delivery of expert services.

Oil & Gas

We’re a partner to many of the world’s leading players in offshore oil & gas operations, with a long track record of support across our services portfolio.

We deploy our expertise on fixed platforms, mobile offshore drilling units, drill ships, FPSO assets and tankers as well as support and survey vessels.

We’re responsible for the inspection and certification of all helidecks on offshore vessels and installations operating in UK and Norwegian waters – over 700 in total – using the criteria in UK CAP437 or Norwegian Civil Aviation Regulations BSL D 5-1 as the basis for our inspections. We also inspect and certify helidecks on a global basis for clients using nationally recognised criteria such as CAP437 or the international standard for helidecks as laid out in International Civil Aviation Organisation (ICAO) publication Annex 14 Volume 2.


We’ve become established as a service provider to the burgeoning renewables sector, partnering with major players for several years to ensure they meet their regulatory obligations. Our long-standing clients include Ørsted A/S and its 108-turbine West of Duddon Sands Offshore Windfarm in the East Irish Sea.

Helicopter operations are often central to windfarm servicing and repair work, and we have a track record in the inspection and certification of both the central landing areas of developments and the hoisting platforms – helihoists – on individual wind turbines.

We also provide expert consultancy and advice on the design and layout of the landing and hoisting facilities.


HCA professionals advise, inspect and certify for clients in a variety of onshore locations, including hotels, hospital facilities, sporting venues and private sites.

For hospitals, we ensure helicopter landing sites – a critical element of their infrastructure – remain fit for purpose in terms of physical condition and adhere to safe operating practices. We routinely audit landing sites and advise on issues such as markings, clearance space and downdraft obstacles. We also focus on awareness training for ground support personnel who are responsible for ensuring the safety of nearby staff and visitors at the time of any helicopter activity. And we advise on potential obstacles that may impact flying operations in ever-changing urban landscapes – a new building adjacent to a hospital complex may present a hazard that will require the identification of a different landing and take-off route for helicopters.

Those same consultancy services are applied to private landing sites at hotels, country houses and sporting venues: we provide guidance on both temporary and permanent sites and offer ground support management for specific events.

Super Yachts

We advise, inspect and certify on behalf of a global network of super yacht clients, applying nationally recognised criteria or the applicable formal international safety standards.

Our inspectors travel worldwide to inspect and certify a current portfolio of approximately 100 super yachts, performing friction testing when required.

We regularly provide initial input on the design, layout and location of the helideck, liaising closely with naval architects and shipyards to offer advice and insights that can help avoid problems or costly alterations at a later date.

The siting of the helideck is often driven by aesthetics, but it’s critical that the potential hazards of turbulence and motion – as well as the issues of obstacle clearance and structure strengthening – are carefully factored into the design process.
