Høj Nordic Marine Contractor

What Høj Nordic Marine Contractor does

Høj Nordic Marine Contractor is a Danish family-owned marine construction company founded in 1958 by Erik Høj and headquartered in Horsens, Denmark, currently owned by Søren Høj. The company provides specialized maritime construction and civil engineering services for ports, offshore wind developers, municipalities, and government entities across Northern Europe, operating from Denmark, Norway, Sweden, Germany, the United Kingdom, and the Baltic region. Its core service portfolio is organized into three areas: port construction and marine works (including dredging, pier construction, boulder clearance, cable installation, diving, MBES surveys, and pumping operations); offshore wind projects (stone beds, scour protection, cable trenches, and decommissioning); and climate-related projects (coastal protection, artificial stone reefs, and waterway infrastructure).

The operational backbone is a fleet of 11 specialized vessels — including M/S Vilma Høj Wire, M/S Camilla Høj, M/S Elisabeth Høj Wire, M/S Alberte Høj Wire, M/S Aase Høj Wire, M/S Lea Høj, M/S Martha Høj, M/S Charlotte Høj, Veluwe, EH3, and Hunte — equipped with wire excavators, pump stations, and trailing suction hopper dredgers. Technical differentiators include MBES (Multibeam Echo Sounder) survey capability for high-accuracy seabed mapping, RTK (Real-Time Kinematic) positioning systems integrated into excavation equipment, and documented performance benchmarks such as up to 1,500 cubic meters per hour pump capacity, 40m excavation depth, 35m boulder clearance, and up to 4km pumping distance. The company holds ISO 9001 certification, DNV-GL Document of Compliance, and Safety Management Certificates for key vessels.

The business model is project-based B2B enterprise services: revenue is earned through direct contracts with ports, energy companies, municipalities, and government entities, with pricing negotiated per project and no public rate cards disclosed. The company operates exclusively through direct enterprise sales with an advisory, early-engagement go-to-market approach, supported by research partnerships (Aarhus University, DTU Aqua) and strategic joint-venture partnerships with firms such as DDW and Hegemann GmbH. Marketing is minimal, relying on a multilingual corporate website, a project reference portfolio, and industry commentary led by CEO Michael Normann. The company is 100% Danish family-owned, with no disclosed funding rounds, and is positioning itself for international growth following its December 2022 rebranding from Rederiet Høj to Høj Nordic Marine Contractor.
