About us

Safety at sea level.

Our mission is to build the most sophisticated and modern marine solutions in the world, to guarantee your safety and comfort at sea.

Our story

Over 67 years of experience.

Founded in 1956, Winel has since become a leading manufacturer of high quality products for the offshore sector and every major shipbuilding market. Based in Assen, Blokzijl and Haiphong, near inland waterways connected to the North Sea as well as the South China Sea, we are an international household name in ports around the world. With around 150 skilled people and our workshops of more than 20.000 m², we’ll take care of your every need to guarantee your safety and comfort at sea.

Our philosophy

We live to innovate.

Innovation is what drives us and we never stop developing our products. Using the latest in Dutch maritime engineering, Winel specializes in manufacturing a wide range of doors, hatches, tank vent check valve systems, platforms, access equipment, passerelles and custom engineered products. Our patented Musketeer system is used in many ships all over the world and is renowned for its excellent operating system: a stainless steel central closing mechanism with a quick acting handle on both sides. Our own R&D team works hard in getting new products on the market on a regular basis.


Winel is a unique partner with in-house engineering, production, assembly and testing of our complete catalog of products. Almost every item is custom built, but in order to guarantee efficient production, everything is designed in a modular way. Our certified welders, together with several notified body shop approvals, are the foundation for the highest quality standard, whether products are made from steel, aluminum, stainless steel or composites. In case our welders need more information, local computer systems connected to 3D viewers create the perfect symbiosis between engineering and production.
