On January 13, 2026, Olav Dale will give an oral presentation about Moorsafe, “The strongest anchor ever“, at EERA DeepWind in Trondheim. The presentation will be based on the abstract below:

Background:

Mooring systems are a critical cost driver and safety factor for floating wind turbines and other

offshore structures. There is a need for innovative anchoring technologies that combine reliable safe

high holding capacity, efficient installation, cost efficiency, and reduced environmental impact.

Objective:

This paper presents the development and performance evaluation of the Moorsafe anchor.

Olav Dale, a Norwegian citizen, is the originator of the unique Moorsafe anchor design

technology designed to deliver high holding capacity relative to its own weight, reducing costs

and enhancing safety, while simplifying handling and minimizing seabed disturbance.

Method:

Field tests in Stockholm archipelago 2005-07-28 under DNV supervision have been conducted with

Moorsafe prototype anchors ranging from 7.5 kg to 76 kg. Performance was assessed in terms of

holding capacity under different load angles and comparison with conventional anchors. Case

studies where Moorsafe anchors replaced traditional concrete block moorings are also presented.

Results:

The DNV test report 40000566-2 shows that Moorsafe anchors performed up to 123 times their

own weight in holding capacity, with over twice the performance of market-leading anchors in

equivalent conditions. In a very early stage, 2000-02-21 and 2000-06-26, we also tested Moorsafe

against Stevpris anchors in Vryhof´s test facilities in Rotterdam, and Moorsafe outperformed

Stevpris with more than twice the holding capacity.

Even in comparison with suction anchors Moorsafe will perform more than twice the holding

capacity and more than halving the anchoring costs.

Moorsafe is truly a disruptive anchor design, outperforming all other anchors by double the

holding capacity which of course is very hard to believe, explaining why most experts think “it must

be to good to be true”. That’s probably why Moorsafe has never got the attention and the funding

needed to succeed in scaling up to offshore size anchors. In spite of all the market headwinds

Moorsafe anchors (30kg and 72kg) have been sold in more than 4000 units and have proven their

superior holding power in a variety of soil conditions.

Moorsafe anchors stable and safe design has proven it can withstand up to 45 degree sideway and

uplift forces.

The Swedish Traffic Authorities planned to anchor a floating road bridge with 22 pcs of 20 tons

concrete blocks = 440 tons, but we did the job with 22 pcs of 72 kg Moorsafe anchors.

The Swedish Coast Guard has chosen the 30 kg Moorsafe anchor for storm anchoring of offshore

oil booms amid the superior holding power and easy installation and retrieval.

Conclusion:

The Moorsafe anchor demonstrates a strong potential as the most cost-effective and sustainable

anchoring solution for floating wind turbines. Its high strength-to-weight-ratio, resistance to

multidirectional loads, and reduced material and CO2 footprint will significantly contribute to

scaling offshore renewable energy.

Further work will explore upscaling of the technology for full-scale floating wind turbines and

long-term performance in offshore conditions under cyclic loading.
