Larsnes Mek Verksted

What Larsnes Mek Verksted does

Larsnes Mek Verksted AS is a privately held Norwegian shipyard established on 2 March 1981 in Larsnes, Sunnmøre (Møre og Romsdal county), specializing in the design, construction, and outfitting of fishing vessels, live fish carriers (brønnbåter), purse seiners, snurrevad vessels, and specialized maritime craft. The company has delivered over 73 vessels since founding and is recognized as one of Norway's leading builders in this niche, holding a YANMAR medium propulsion service station certification and tracing its craft traditions to 1916. Its technical differentiation rests on hybrid diesel-electric propulsion with Siemens battery packages (~600 kWh to 1.5 MWh), TIER III emission-compliant machinery with Emigreen SCR systems, zero-emission closed-transport fish welfare systems (water circulation, UV treatment, automated washing and disinfection, parameter logging), and the world's first Wavefoil bow foils on a live fish carrier. The yard pioneered the hybrid live fish carrier with Ro Vision (Ship of the Year 2020) and the combined bløgge/snurrevad vessel with Kapp Linné (build no. 73, 2026).

The company generates revenue through project-based new vessel construction (one-time contracts typically valued NOK 250M-600M+ per vessel), repair and maintenance services, vessel rebuilding and conversion, and usage-based shore power services at its 350m quay. Hulls for certain projects are produced by Marine Projects Ltd in Poland's Gdynia-Gdańsk area while final assembly and outfitting remain in Norway, retaining 75-80% of commercial project value creation domestically. Go-to-market is direct enterprise sales led by the CEO and management team, with design collaboration through partners Skipskompetanse AS and SeaCon AS.

The shipyard is majority-owned (68.75%) by Rostein AS — a Harøy-based live fish carrier operator that is both the controlling shareholder and the largest customer, with cumulative orders approaching NOK 5.5 billion across 13+ vessels. In June 2025, Larsnes Mek and Ulstein Group announced a joint bid for 28 standard vessels for the Norwegian Navy, marking a strategic expansion into defense. The yard operates modern facilities completed in 2023-2024 including a covered dry dock claimed as Norway's most time-efficient (1.5-hour empty/fill cycle), 350 meters of quay, and shore power infrastructure across multiple voltage configurations.

Expansion highlights5 records

Direct peers

• Aas Mek Verksted: Norwegian shipyard on the West coast building fishing vessels, well boats, and service vessels. Comparable in customer base and product category, particularly in live fish carriers and smaller specialized vessels for the Norwegian maritime cluster.
• Simek (Firda): Norwegian shipyard (Simek AS, part of Firda) building fishing vessels and smaller specialized craft in the Sunnmøre/Western Norway cluster. Comparable scale and product focus on coastal and offshore fishing vessels.
• Myklebust Verft: Norwegian shipyard in Gurskeia/Ålesund region building advanced fishing vessels and offshore support ships. Direct peer in the Norwegian fishing vessel segment with similar specialized newbuild capability for coastal and offshore fleet operators.
• Kleven Maritime: Norwegian shipyard (part of Vard/Fincantieri group) with strong heritage building offshore support vessels and fishing vessels from Myklebust Verft. Comparable in target customer base (Norwegian maritime operators) and capability scope (newbuild + repair at modern facilities).
• Havyard: Norwegian shipbuilder specializing in fishing vessels, fish carriers, and offshore vessels. Direct competitor in the same product category serving similar Norwegian fishing fleet and aquaculture operators, with comparable hybrid/zero-emission vessel development.
• Ulstein Group: Norwegian shipyard headquartered in Ulsteinvik with comparable modern facilities including covered dry docks. Direct peer for specialized vessel construction, with explicit 2025 partnership with Larsnes for Norwegian Navy 28-vessel program. Both target similar Norwegian maritime cluster customers and use Polish hull partners.

Regional players

• Westcon Yards: Group of Norwegian shipyards (Florø, Stord, etc.) historically building offshore and fishing vessels. Comparable as a Norwegian shipbuilding group with newbuild and repair capability, though currently focused more on offshore wind and service operations.

Others

• Rostein AS: Majority owner (68.75%) of Larsnes and largest customer. While not a direct shipyard peer, Rostein operates one of Norway's largest live fish carrier fleets and is the captive demand source for Larsnes' well-boat newbuilds—an essential ecosystem participant.
• Skipskompetanse AS: Long-term naval architecture partner of Larsnes (since 2009), designing the LFC 2020 series (SK-6100, SK-6000, SK-3151) and other vessels. Adjacent ecosystem participant—design partner rather than competing shipyard—critical to Larsnes' design differentiation.

Broad incumbents

• Vard (Fincantieri): One of the largest global shipbuilders, with Norwegian operations building offshore support, specialized vessels, and fishing-adjacent ships. Broader incumbent offering overlapping capabilities as part of Fincantieri's wider portfolio; not specialized in Larsnes' niche of small-batch fishing vessels and live fish carriers.
