What Enshore does

Enshore Subsea is a UK-based subsea trenching and cable installation contractor that delivers turnkey Engineering, Procurement, Construction, and Installation (EPCI) solutions for shallow water and hard ground environments. The company operates one of the world's leading fleets of submarine cable trenching equipment, headlined by the T3200 — billed as the world's largest and most powerful subsea trencher with 800kW cutting power and trench depth to 3.5m — together with the ENS1600, ENS1100, T1, and SWT-1 trenchers, the PCP Power Cable Plough, APP Advanced Pipeline Plough, and Carrera 4 controlled flow excavator. Enshore jointly owns the CMOS Installer DP2 cable lay vessel with Belgian marine contractor Herbosch-Kiere, and is building the purpose-built Enshore Advantage shallow draft cable lay barge for delivery in Summer 2026.

The company monetises through professional-services contracts: turnkey EPCI project delivery for offshore wind developers (export and inter-array cables) and transmission system operators (grid connection systems), trenching and specialist offshore subcontracting (asset hire through to vessel-inclusive solutions), subsea cable installation across power and fibre optics, technical services (equipment maintenance and modifications), and survey/UXO identification via the RapidScan Subsea multispectral tool. Customers are concentrated in large enterprise and government buyers — Nexans/TenneT Germany, SSEN Distribution, the Inch Cape Offshore Wind Farm joint venture (ESB and Red Rock Power), and MCA-Sénégal II — accessed through enterprise field sales, competitive tenders, and multi-year framework agreements.

Enshore was acquired by Saudi conglomerate Algihaz Holding in 2021 after facing closure in 2020, has since opened offices in Paris (May 2024) and Rotterdam (November 2024), and in January 2026 secured a £100m HSBC UK funding package to support three German North Sea projects under its six-year framework with Nexans. Reported 2024 revenue was approximately £60m with £6.6m operating profit.
