About us

At Mammoet, we provide solutions for lifting, transporting, installing and decommissioning large and heavy structures. We could talk for hours about the equipment we use, and about how sophisticated and powerful it is. But all that power means nothing without a plan. In fact, we believe our business isn’t about size. It’s about: time.

Uptime. Turnaround time. Time to market. To our customers, time is the currency that matters most. That’s why we strive to bring their deadlines forward. It’s an integrated, daily effort shared by everyone at Mammoet. That’s how we move time for our customers. So time isn’t set in concrete. Or forged in steel. It’s not even all that heavy.

And yet, it’s the biggest thing we can move for you.

Five common values

Mammoet serves customers by moving large and heavy objects. Mammoet really excels when it helps its customers move time. By providing smart solutions, Mammoet safely and professionally moves deadlines forward, improves uptime and reduces the cost of ownership. It is the challenge of pushing boundaries, creating new possibilities, and accomplishing the exceptional that moves Mammoet as a team.

Shared drive moves Mammoet. The Mammoet team is made up of a group of dynamic and diverse individuals – individuals from different countries, cultures and backgrounds. We share a strong bond that arises out of shared principles: integrity and loyalty and a shared drive:


Love the work

Working at Mammoet is not just any other job. Here people share a deep commitment to the work they do and a desire to excel by building craftsmanship and dedicating their talents. We love the challenges of the industry and the equipment that comes with it. Across all disciplines, ages and cultures, one common theme is that we all have a sense of belonging to something bigger than ourselves; something that moves us.


Results count

We are willing to take on tremendous challenges. Our desire is to achieve things that nobody believed possible. For us, it is not just about accepting the challenge, but about delivering the desired results. We go the extra mile, and then the extra inch. Whether in safety performance, or bringing down environmental impact, in building teams, in getting a contract, or executing the job, in making a profit, it is the result that always counts. We move for results.


Take care

People, communities and the environment require care. We make safety a top priority, always and everywhere, so that after a day’s work everybody can return home unharmed. We treat people fair, with clear feedback and rewards for results. We contribute to the communities that we work in. From our position as an industry leader we will actively contribute to sustainability, in our own company, with suppliers and with customers. We move with care.


Perform as a team

Our customers demand excellent performance; and so do we. We believe excellent performance can only be achieved through team effort. Everybody is expected to take his role in the team and bring maximum contribution. In a team, diversity drives performance; people build on each other’s strengths and step up to compensate shortcomings. We move as one.


Be responsible

Mammoet is a big international company. This position brings the responsibility to set standards and drive development. In this company, everybody has a job to do. With each job come specific responsibilities. Everybody has to stand for his work and ensure it meets industry and Mammoet standards. Jointly we are responsible for a sustainable future of our company. We expect people to speak up when it is for the benefit of the company. We expect others to listen and act if required. We step up and take responsibility; we move.

From then to now

On May 13, 1807, Jan Goedkoop purchased a 140 ton sailing cargo ship, ‘Twee Gebroeders’ (Two Brothers). The first Industrial Revolution (Factory Age) was just a few decades old and the second one, the Transportation Age, was still to come. The Dutch monarchy wasn’t even in existence yet (1813).

Jan Goedkoop was one of many visionary entrepreneurs who would lead companies, out of which the current Mammoet emerged. He foresaw the ever greater need for transportation in a growing and industrializing society. In fact, with ‘Gebroeders Goedkoop’ he set the tone for a company that is always at the forefront of market developments, even defines them. In the decades that followed, a transportation company grew with numerous freight and passenger ships, and salvage services.


In 1966 Van Seumeren Kraanbedrijf was founded, active in crane rental. Frans van Seumeren is the son of the founder and came to work with the company in 1973. The family Van Seumeren would be pivotal in the growth and professionalization of the global market for heavy lifting and transport. They would initiate numerous innovations in equipment and processes, always pushing the boundaries of what technology and imagination can realize.


In 1971 Gebroeders Goedkoop merged with heavy transport & lifting company ‘Van Wezel’ to form ‘Mammoet Transport’. In 1973 Mammoet Transport became part of ‘Koninklijke Nederlandsche Stoomboot Maatschappij (KNSM) in Amsterdam, and changed its name to Mammoet. In 1973 Mammoet Shipping was founded. KNSM was sold to Nedlloyd in 1981.


With the help of private equity firm NPM and a bank, Van Seumeren acquired Mammoet in 2000. Acknowledging the better resonance of the name ‘Mammoet’ in a global market, the merged company was called Mammoet. The lifting of the Russian submarine ‘Kursk’ in 2001, brought international fame for Mammoet and added to a tremendous growth of the company in the years to come, from several hundred million euros in 2001, to over a billion in 2011. In 2006, SHV Holdings acquired the majority of the shares in Mammoet from its subsidiary NPM and the bank. In 2011, SHV acquired the remainder of the shares.

In the last four decades, Mammoet has evolved into a world market leader in the field of engineered heavy lifting and transport. We have been able to do so thanks to a team of creative engineers, numerous innovations in equipment – be it in cranes, jack-up systems, gantries or trailers - and a professional workforce, renowned for its craftsmanship and adherence to the highest safety standards.
