Acteon

Offshore energy equipment and services provider

Overview

Acteon provides equipment and services for offshore energy projects across the full field lifecycle, from foundations and moorings to surveys and ongoing maintenance, via a globally integrated group of specialist companies. It grows by acquiring firms with complementary skills to build an end-to-end offering, using its fleet, survey and support capabilities, and engineering expertise to handle projects. The company stands out by delivering a single, multi-disciplinary service across a wide geographic footprint rather than a single-product vendor. Its goal is to become a stable, leading offshore energy provider by expanding capabilities and footprint through selective acquisitions and private-equity backing.

Cadeler acquires Menck for $578m to expand offshore wind operations.

Cadeler acquires Menck for $578m to expand offshore wind operations. The acquisition is financed through Cadeler's available funds and a €380m facility from DNB Bank and Coöperatieve Rabobank. Danish offshore wind installation contractor Cadeler has acquired Menck, a German provider of equipment and technology for offshore foundation installation, for €501m ($578.1m). Following the completion of all required regulatory approvals, the agreement allows Menck to continue operating as an independent business within the Cadeler Group. Cadeler acquired Menck from Acteon, an offshore energy services firm based in the UK that delivers engineering and operational solutions for offshore assets throughout their lifecycle. Funding for the deal includes both Cadeler's existing liquidity and a €380m acquisition facility jointly arranged by DNB Bank and Coöperatieve Rabobank. Cadeler intends to replace the acquisition facility with longer-term financing and future operational cash flow. Menck offers hydraulic impact hammers, noise mitigation solutions, drilling, grouting, and lifting services for fixed-bottom offshore foundations. The company's equipment and expertise have been used on various projects, including supplying a 4,400kJ impact hammer for Cadeler's ongoing work at the Hornsea 3 offshore wind project. According to Cadeler, keeping Menck as a standalone business is a central part of the acquisition, ensuring the preservation of Menck's organisational structure, market relationships, and operational approach. Cadeler CEO Mikkel Gleerup said: "Offshore wind projects continue to increase in scale and technical complexity, making reliable execution more important than ever. Menck has built an outstanding reputation over more than 150 years as a trusted provider of mission-critical foundation installation equipment and engineering expertise. "Bringing together Menck's specialist engineering capabilities with Cadeler's offshore installation proficiency, we are combining highly complementary strengths that will enhance our support to customers across the full installation value chain." Menck will continue to supply equipment and services to other contractors across the offshore wind industry, retaining its market identity. Cadeler operates one of the largest fleets of jack-up wind installation vessels and has positioned itself for large-scale, complex offshore projects. The company indicated that bringing Menck's engineering expertise and technical solutions alongside its own fleet will allow it to offer a more integrated approach to the transportation and installation (T&I) of wind foundations. Both companies share a model focused on leveraging technical and operational know-how to maximise the value and utilisation of their asset bases. Cadeler expects the acquisition to enable more efficient project delivery, reduce dependency on subcontractors, and increase project flexibility, while maintaining Menck's access to the wider market. In June 2026, Cadeler completed the installation of 100 Siemens Gamesa wind turbines at RWE's 1.4GW Sofia offshore wind farm in the UK North Sea.

Searénité consortium to advance marine noise mitigation.

Searénité consortium to advance marine noise mitigation. Tuesday, April 7 2026 General - noise mitigation. Chantiers de l'Atlantique, EDF power solutions, Heerema Marine Contractors, Menck, RTE, Sealence and Smulders have formed a consortium to develop a cutting-edge noise mitigation system for offshore wind operations. The growth of offshore renewable energy presents an important opportunity to further strengthen our commitment to responsible operations. Understanding and managing underwater noise becomes increasingly essential to protecting marine ecosystems. Activities such as ship traffic, sonar use, and offshore construction can affect marine life over large distances. Offshore wind farm installation is one of these activities. While industry players have already implemented mitigation measures, Searénité aims to go further, introducing advanced technologies tailored to the marine environment to minimize potential impacts even more. The objective of the Searénité project is to adapt the SubSea Quieter, an innovative technology designed to reduce underwater noise, to the specific requirements of floating wind turbine deep anchoring and offshore electrical substations foundations. Developed and patented by Sealence, SubSea Quieter uses flexible panels made from an air-inflatable membrane. These panels are deployed underwater around offshore foundations during their installation, acting as an acoustic shield to reduce underwater noise. The result is effective noise reduction using a straightforward, cost-effective, and environmentally friendly solution suitable for deep-water installations. This marks a significant technological step toward sustainable coexistence between energy development and marine biodiversity conservation. Year one will focus on specifying SubSea Quieter for floating wind turbine anchors, offshore substations, and wind turbines using jacket-type foundations. Activities include design work, acoustic modeling, and hydrodynamic behavior analysis under wave and current conditions. Pressurized tank tests will validate acoustic performance down to 300 m water depth. Subsequent years will involve prototype production and testing in 2028 at the Port of Saint-Nazaire, followed by refinement and improvement. Subject to successful evaluations, a full-scale demonstration is also foreseen during the installation of an electrical offshore substation. The Searénité project was awarded a grant of €7.1 million. The French State funds this project as part of France 2030 operated by ADEME.
