Asso.subsea secured multi-project subcontract from Nexans on 11 December 2025 for subsea cable installation and protection on TenneT's 2 GW offshore grid programme, including LanWin4 alongside BalWin3 and LanWin2. The scope covers more than 650 km of offshore cable burial and over 60 km of nearshore cable laying and burial campaigns scheduled for execution between 2027 and 2031, using Asso.subsea's cable-laying vessel Atalanti and dedicated trenching systems. For LanWin4 specifically the campaign window runs toward the 2031 commissioning date, with nearshore Wadden Sea sections contracted to sister subcontractor Enshore Subsea (separate role record). Asso.subsea is acting under Nexans' EPCI framework contract with TenneT and is a subcontractor, not a direct TenneT counterparty. Contract value not disclosed publicly.
