RIVE Private Investment acquires a four-helicopter portfolio from Milestone Aviation, supporting offshore wind and oil sectors in the North Sea.
This article is based on an official press release from RIVE Private Investment.
RIVE Private Investment, a European investment firm focused on transportation and energy transition assets, has announced the acquisition of a four-helicopter portfolio from Milestone Aviation Group. The transaction, which was finalized in late 2025 and announced in January 2026, underscores the growing intersection between aviation finance and renewable energy infrastructure.
According to the company’s official announcement, the deal involves three Leonardo AW139s and one Leonardo AW169. These assets are currently leased to specialized operators supporting critical offshore industries. The acquisition aligns with RIVE’s broader strategy to invest in assets that contribute to decarbonization and essential services.
The agreement between RIVE Private Investment, acting through its RIVE Transportation Assets Income Fund, and Milestone Aviation Group (an AerCap company) was signed on November 6, 2025. The portfolio consists of four twin-engine helicopters manufactured by Leonardo, a leading aerospace company.
The specific assets acquired include:
RIVE confirmed that the acquisition was supported by senior debt financing provided by Investec, a South African bank described as a repeat partner for the investment firm. The deal structure involves acquiring the aircraft with existing lease contracts already in place, ensuring immediate revenue generation.
“The transaction… involves three Leonardo AW139s and one Leonardo AW169.”

The portfolio is heavily weighted toward the renewable energy sector, reflecting the operational demands of the North-America Sea region. According to the release, the helicopters are leased to two primary operators: HeliService and Uni Fly.
Three of the four helicopters are dedicated to the offshore wind industry. These aircraft are equipped with hoists to transfer technicians and equipment to wind turbine nacelles off the coasts of the United Kingdom and Germany. This deployment highlights the critical role of vertical lift in maintaining offshore wind farms, which are moving further out to sea where crew transfer vessels are less efficient. The press release highlights the expertise of the lessees:
The fourth helicopter in the portfolio is currently deployed for offshore oil and gas operations, providing a diversified revenue stream while the majority of the assets support the energy transition.
This transaction illustrates a maturing trend in aviation finance where specialized investment funds are increasingly acquiring assets from major lessors like Milestone to target specific ESG (Environmental, Social, and Governance) niches. By focusing on helicopters that support offshore wind, RIVE is effectively categorizing these aircraft as “energy transition assets” rather than just transportation hardware.
For Milestone Aviation, the sale represents an opportunity to recycle capital while maintaining a relationship with the assets through a financial partner. For the broader market, it signals continued confidence in the Leonardo AW139 and AW169 as the workhorses of the North Sea energy sector.
