General Contractor
One contract. One point of contact. Full responsibility.
As a general contractor, we coordinate all necessary trades, subcontractors, and interfaces, assuming full technical and organizational responsibility. For you, this means clearly defined areas of responsibility instead of losing track of interfaces during the project.

05
Documentation
Quality assurance and reporting
Documentation
Every weld, every torque value - verifiable in docBox.
Documentation is a top priority in our business. That is why our teams record every work step directly on-site using our in-house app—not from memory on paper at the end of the day.
Data entry directly at the turbine - Inspection reports, photos, and measurements are recorded where they happen, even offline.
Comprehensive rather than random sampling - every defect is located on technical drawings, making it easy to identify and find again.
Analysis in your own dashboard - Defect patterns and clusters are analyzed instead of getting lost in individual reports.
Handed over ready for acceptance - You receive the complete documentation at the end of the project, not weeks later.
Areas of application
At home at sea. Just as strong on land.
Offshore wind is our core market—the processes, qualifications, and certifications behind it apply wherever expertise in steel construction and professional mechanical work is required.
Core market
Offshore wind energy
Wind farms, substations, and converter platforms in the North and Baltic Seas – our core and home market, where we have been permanently active for years.
Energy infrastructure
Substations, transformer stations, and grid connections on land – at the same quality and safety level as offshore.
Cranes & lifting technology
Inspection, repair, and maintenance of support structures, also applicable to onshore steel structures without restriction.
Industrial plants
Steel construction, inspection, and maintenance during ongoing operations – tailored to your shutdown windows.
Hydraulic steel structures
Locks, weirs, and piers: maintenance under water influence, using rope access instead of scaffolding.
Why mh²
Our people make the difference.
Offshore work rarely goes according to plan. Weather, technology, and time windows change, often within a single shift. That is why we primarily use our own staff: people who know each other, know the systems, and know exactly what needs to be done without needing long consultations.
Our own employees
Mostly permanent technicians who have been working together at sea for years. This reduces error rates and ensures safety in confined spaces.
Offshore professionals
Mechanical all-rounders who weld, assemble, bolt, and work on ropes. All relevant offshore qualifications and safety training are in place and up to date.
Strong project management
We consolidate schedules, interfaces, and documentation on shore. For you, this means one point of contact instead of dealing with multiple site contractors.
In-house tools & equipment
From torque wrenches and welding equipment to complete rope access gear, we bring our own tools — tested, calibrated, and ready for immediate use.
Certified and tested
ISO 9001, 14001 and 45001, EN 1090-2 EXC3, ISO 3834-2 and SCL Level 3 — plus 16 procedure qualifications. Regularly audited and fully documented at all times.
Collaborative problem solvers
In large-scale projects, things rarely go exactly to plan. When the findings differ from the drawings, we work closely with our clients to determine the necessary steps and implement the best possible solution together.
Project highlights
Projects we are particularly proud of.
Sister company — mh² Inspection
Independent testing — from the same group.
Our independent sister company, mh² Inspection, handles everything related to inspections, assessments, and reporting.

Careers
Working offshore means being a team player.
We are looking for welders, industrial mechanics, fitters, and project engineers who want to be a permanent part of our team and help us grow the company – not just for one project, but for the years to come.
