From then to now

It all started in 1807...


Mammoet’s history started on 13 May 1807 in the Netherlands


When Dutch entrepreneur Jan Goedkoop founded a maritime company at the age of 25, with the purchase of a 140-ton cargo vessel. It was the beginning of the Industrial Revolution, and Goedkoop foresaw that heavy transport would be in high demand.

The company, called 'Gebroeders Goedkoop' (‘Goedkoop Brothers’), offered both cargo and passenger transport on water. In 1862 the company acquired its first tugboat, and from 1920 onwards, the company focused on tug and salvage services.

In 1971, the companies Goedkoop and Van Wezel merged to form Mammoet Transport. In 1972 another company was acquired, Stoof Breda, which at that time was one of the Dutch market leaders in engineered heavy lifting and transport.

In 1973 Mammoet Transport became a subsidiary of Koninklijke Nederlandse Stoomboot-Maatschappij (KNSM) in Amsterdam. At the same time, the company name was changed to Mammoet. In 1973 Mammoet Shipping was founded. This enabled Mammoet to reinforce its "factory-to-foundation" concept, which allowed the company to transport large objects, such as vessels and modules, from the factory to their destination site – anywhere in the world – and install them.

In 1983 Mammoet develops a revolutionary container-sized Self-Propelled Modular Transporter (SPMT), now widely used industry-standard equipment.

In 2000 Mammoet was acquired by and merged with Van Seumeren Kraanbedrijf, a company that had been founded in 1966. In 2001 Mammoet Mammoet raised the Russian nuclear submarine wreck Kursk, using over 3,000t of tailor-made equipment, this became one of the signature projects of the company. In the same year, it sold its maritime branch Mammoet Shipping to shipping company Spliethoff Group.

SHV Holding, a privately owned Dutch trading company, acquires Mammoet in 2006.

In 2020, Mammoet merged with UK-based engineered heavy lifting company ALE, forming the largest engineered heavy lifting and transport company in the world.
