Maintenance and Operational Excellence
NHV’s maintenance
procedures exceed EASA’s regulatory
requirements,
leveraging advanced technology and best practices to ensure aircraft safety and reliability. Operational protocols are regularly updated to meet the
latest
safety standards. Steve McNeil, NHV’s chief of maintenance in Denmark, previously led maintenance in
Africa for progressive 10 years. At
Esbjerg Airport, NHV follows a
maintenance
schedule based on flight hours and calendar time, covering inspections up to 800 hours. Engineers hold B1.3, B2, and C licenses, allowing them to oversee conformity to regulatory requirements and handle turbine engines, instrumentation, and electronics. The maintenance schedule includes checks at 10, 50, 100, 150, 200, 280, 400, 600 and 800 flight hours. Despite operating up to seven days a week, the availability of helicopters for operational deployment
remains above
85% thanks to rigorous maintenance and repairs.

Strategic Growth
In May 2023, NHV A/S secured a significant contract with TotalEnergies EP Denmark to support offshore operations in the Danish sector of the North Sea. From Esbjerg Airport, NHV deployed a dedicated H175 helicopter to transport personnel and equipment to TotalEnergies’ installations in the Dan and Tyra fields. This marked a key step in NHV’s growth in the offshore oil and gas sector.
In July 2024, NHV further expanded its portfolio by securing a 3+2-year contract renewal with INEOS, with potential extensions. As Base Manager Eriksen explained, NHV is responsible for daily crew changes, flying personnel offshore every day to the rigs. “Sometimes they need additional flights, especially during severe weather, and we ensure we support them,” she noted.

Each day, NHV typically operates two to four flights for both INEOS and TotalEnergies. However when weather delays such as high waves or lightning occur, the company coordinates additional flights to catch up. “Each flight takes between two- and-a-half hours to four hours, and we need to plan carefully to ensure everything is operational. Our engineers also perform checks between flights,” Eriksen added, emphasizing the daily coordination required.
On any given day, NHV transports between two and 16 passengers per flight, with 12 to 16 passengers being typical. In some cases, if a single passenger’s transport is essential, NHV accommodates the request. However, weather is the most significant factor influencing operations. Bad weather such as storms or high waves can lead to delays of one or two days before flights resume.
