More than ever, clients are looking for tailored solutions.

Jan De Nul strongly believes that innovation is the key to discover new applications for existing problems. Or simply to create a better future. In complex and challenging projects, our creativity can make a difference.

Using nature to protect biodiversity

From the very start of a project, we search for sustainable and cost-efficient solutions. In the engineering phase, we already take the protection of biodiversity into account, closely monitoring the features and performances of ecosystems. These nature-based solutions apply construction and remediation techniques that make use of natural materials. With our help, nature further develops and maintains itself.

AquaForest

We take our responsibility as a marine and civil player, and commit to solutions that benefit both people and nature. The AquaForest project in Guayaquil, Ecuador, is a case in point. The goal? To create and restore a mangrove habitat.

Coastbusters

After six years of experimentation and scientific observation at sea, a new nature-based coastal protection technique is on the table. One of the innovative elements in it is the so-called mussel shaker. The new technique uses mussels to build a reef that acts as a biologically-reinforced dune-by-dike underwater, as the first hurdle against storm surges. Beach and dunes then become the second line of defence.

Underwater breakwater in Benin

For years, the waves of the Atlantic Ocean have been eroding the coastline of Benin. To protect the coast, we installed a 5 km long underwater breakwater that also serves as a coral reef. They strengthen each other in their primary function: breaking the waves and reducing their impact on the coastline.

How did we break the power of the waves?

Equipment design

In order to act innovatively, you have to be innovative.

We constantly adapt our equipment and techniques to keep the impact on fauna and flora as low as possible. In our commitment, we are prepared to go far. If something does not exist yet, we create it ourselves.

Sound-absorbing bubble screen

Driving piles into the seabed can cause noise pollution. We strongly dampen these sound waves by using sound-absorbing installation tools and by simultaneously creating sound-insulating air bubble screens around the vessel.
Next-generation vessels

We designed our newbuild vessels Voltaire and Les Alizés as gasoil-powered vessels equipped with a highly advanced dual exhaust gas filtration system comprising a Selective Catalytic Reduction (SCR) and a Diesel Particulate Filter (DPF). On top of that, Les Alizés will also be equipped with a battery that will recover energy during certain actions.
Minimal ground pressure

Our intertidal ploughing vehicle Sunfish has a ground pressure no higher than that of a human being. An ideal machine to bury export cables in nature-sensitive areas.
Vacuuming plastic particles

Historical pollution of plastic particles is a major issue. To deal with this problem, we designed the Nul-O-Plastic: a flexible and compact vacuum cleaner with a long hose that hoovers up the plastic particles in the container. Once the container is full, it is emptied in a central depot. The rubber caterpillar tracks of the machine ensures minimal impact on the soil.

Sharing Knowledge

How do you keep innovating in a sustainable manner?

By sharing expertise and experience, both within the company and beyond. Interaction with new and refreshing ideas encourages us to think out of the box. Jan De Nul shares its know-how and insights with educational institutions and (sector) federations worldwide.

Our internal platforms JDN Wiki and Expert Academy gives all employees immediate access to the rich variety of knowledge that is present in the company.

By connecting colleagues with different ideas, perspectives and approaches, amazing new concepts pop up.

Our internal Innovation Challenge brings colleagues from all departments together to work on their favourite innovation topic. But at Jan De Nul, don’t just imagine and think, we also act. Our in-house experts support the winning teams to further develop their ideas. To further stimulate the synergy within the company, the Innovation taskforce has been integrated in the CSR policy.

What drives our employees to keep innovating?

If we share knowledge, the entire sector benefits.

In several institutions and federations, we take on an advisory and executive role. We are even a founding member of The Blue Cluster, a Belgian federation that connects a total of 200 entrepreneurs, researchers and policy makers. Together we design sustainable business models, set up creative partnerships and develop groundbreaking technology within the blue economy.
