Proving the Unprovable: How Heavy-Lift Equipment Earns Its Trust
Heavy lifting is at the heart of offshore energy and large-scale infrastructure. Whether it’s installing a wind turbine, handling a monopile offshore, or certifying crane hooks in a port, the stakes are enormous.
A single failure can mean costly delays, reputational damage, or worse — risk to human lives. That’s why before any lifting tool goes into operation, it must first prove itself in our Proof-Load Testing Laboratory, our 5,100-ton testing rig.

More Than Compliance: Protecting People and Projects
Behind every ton of steel we test, there are workers offshore whose safety depends on it. That’s why we go beyond compliance and certification — because safety is never negotiable.
Every test is carefully planned and risk-assessed. From the moment a component arrives at our quay-side facility, a safety protocol is activated: logistics, storage, rigging, test planning, monitoring, dismounting, inspection, and reassembly.
This structured process ensures not only reliable results but also a safe environment for everyone involved.

From Offshore Wind to Oil & Gas and Beyond
The range of equipment that comes to our facility is as diverse as the industries we serve:
- Blade clamps, nacelle yokes, and tower lifting tools for wind turbine installation.
- Monopile lifting devices and transition piece appliances for the next generation of offshore wind foundations.
- Crane hooks and crane components used in ports and offshore platforms.
- Special lifting tools for aerospace, railway, and scientific projects.
Each test is different. Each brings a new challenge. And with every proof-load, we gain experience that makes the next test safer, faster, and smoother for our clients.
Why Basajaun?
Named after a mythological giant, Basajaun is one of the few rigs in the world capable of handling such massive loads.
- Quay-Side Location (Pasaia, Spain): Components can arrive directly by sea and be tested without unnecessary inland transport.
- Modular & Scalable Setup: Extra modules can be added to test larger and heavier components as offshore projects grow in size.
- Real-World Simulation: Our instrumentation replicates worst-case scenarios to ensure reliability under extreme conditions.
- Independent Certification: Witnessing by DNV, TÜV, Lloyd’s, ABS or other third parties is always supported, with complete CE/ASME/custom documentation.
A Day in the Life of a Test
When a 960-ton capacity nacelle yoke arrives at our quay-side, it’s lifted straight to the test rig.
Within hours, it faces forces far beyond anything it will ever experience at sea.

Sensors capture its every reaction, engineers analyze data in real-time, and certifiers watch the process unfold live — on-site or remotely (upon request).
Once it passes, the tool is dismounted, inspected, measured, and certified, ready to be shipped to its final destination.
For the client, the peace of mind is priceless: “the tool has already proven itself under harsher conditions than it will ever face in the field”.
Constantly Learning, Constantly Improving
Every proof-load test brings something new: a different geometry, a higher load, or a novel testing setup. With each challenge, we refine our procedures, broaden our know-how, and improve the overall experience for our clients. That means shorter lead times, smoother processes, and safer tests every time.
The Bigger Picture
Basajaun is more than a test bench. It is becoming a strategic hub for Europe’s offshore and heavy-lift industries.
By combining design, manufacturing, and testing under one roof — and by situating it quay-side for maximum logistical efficiency — we are not only certifying equipment. We are accelerating the global deployment of offshore energy and critical infrastructure.
As turbines grow taller, monopiles heavier, and offshore projects more demanding, Basajaun is ready to meet the challenge.
Because in offshore and heavy-lift industries, trust is built not only on design — but on proof.
