**August Debouzy and A&L Goodbody (ALG) advised Aventa, an independent group specialising in marine energy and offshore transmission infrastructure, on its acquisition of Irish Sea Contractors (ISC), an Irish marine contractor specialising in marine civil engineering, commercial diving and subsea cable projects.**

Founded in France in 2010, Aventa supports marine energy and transmission projects through its Consulting, Engineering and Operations businesses, with particular expertise in subsea cables, interconnectors and offshore wind. Based in County Wexford, ISC brings more than 40 years of experience in marine works and provides construction, installation, inspection, repair and maintenance services in Ireland and internationally.

The acquisition strengthens Aventa’s operational capabilities and enables the group to provide clients with a more integrated offering, from planning and engineering through installation and long-term maintenance of offshore infrastructure. It also gives Aventa an operational base in Ireland, combining the group’s technical and international project capabilities with ISC’s marine delivery experience.

**August Debouzy** advised Aventa with Julien Wagmann (Partner), Coralie Foucault (Senior Associate) and Hortense Coulon (Associate) in Corporate/M&A, together with Elie Bétard (Counsel) in Tax.

**A&L Goodbody (ALG)** advised Aventa on Irish law matters with a Corporate/M&A team led by Phil Fogarty (Partner), supported by Gavin Dowd and Andrew McClintock, together with Michael Doyle, Matthew McGrogan and Emer Gilmore (Employment), Vincent Power and Peter Murphy (Maritime Regulatory), Brendan Curran and Chris Stynes (Environmental), Aideen Burke and Claudia Holland (Tech), Hannah Shaw, Conall Vallom and Ivan Rakhmanin (Disputes & Litigation), and Stephen Egan, Philip McQueston, Cian Ryan and Louise Kennedy (Tax).
