S.E.M Lorient Keroman

What S.E.M Lorient Keroman does

S.E.M Lorient Keroman is a Société d'Économie Mixte (mixed-economy company) operating under Lorient Agglomération that manages the Port de pêche de Lorient Keroman, the leading fishing port in Brittany and the second-largest fish auction in France by volume. The port operates as an integrated maritime hub serving 275 companies, 280 regular fishing vessels, 620 sailors, and approximately 3,000 direct jobs across fishing, wholesale (mareyage), seafood processing, logistics, and ship repair activities. Its core products are port infrastructure services — fish auction sales (La Criée / Gare de Marée), 7,000 m² of positive cold storage, mariculture warehouse rentals, treated seawater networks, and a 16-hectare ship repair area equipped with a new 800-ton lifting crane. The facility operates 24/7 without tidal constraints and handles 80,000 tonnes of seafood annually.

The port's underlying technology stack is conventional industrial infrastructure rather than software: a computerized auction sales system for coastal and high-sea products, treated seawater networks, fiber optic access, and ISO 14001-certified environmental management. It is the #1 French port for live langoustine landings (983 tonnes in 2021) and ranks #1 in Brittany and #2 nationally in fish auction volume (16,000 tonnes in 2025, generating €71.8 million in total seafood turnover). The ship repair area (7 hectares at Keroman plus 9 hectares at Lanester) handles fishing, commercial, pleasure craft, and occasionally defense vessels, generating approximately €20 million annual turnover with 200+ direct jobs, having grown roughly 20% since 2018.

The business model is multi-stream and asset-heavy. Revenue is generated through (i) auction commissions on fish and seafood landings at La Criée, (ii) port fees and warehouse rental income (e.g., €13.74/m²/year for mariculture warehouses), and (iii) ship repair area services. Pricing for land concessions is provided on inquiry. The customer base is diversified across professional fishing vessel operators, wholesale fish buyers (mareyeurs), seafood transformation companies, and ship owners — with no single customer concentration. Strategic capital is publicly funded: Région Bretagne has invested over €52 million in port infrastructure since 2017, with €11 million dedicated to the ship repair area since 2018. The port holds the Pêche Durable sustainable fishing label (France Agrimer, 2026) and ISO 14001 certification, and is actively engaged in maritime safety partnerships (IMP, CROSS Etel) and innovation promotion through events like Navexpo and the Lorient Océans Festival.
