Seijsener for port and marina services

When it comes to technical facilities for ports and marinas, Seijsener is the first name that springs to mind worldwide. Expertise, creativity, quality and commitment drive what we do. Our good reputation stems from almost 60 years of know-how and the desire to always offer our customers the best possible, tailor-made facilities, since no two marinas are identical. Location, target group, regulations, personal preferences: Seijsener combines them with you into a technical installation that fits your marina like a glove.

Own design and manufacture

We aim to realise a marina layout that will last for many years to come, without a problem. Even under extreme circumstances such as wind, salt water and waves. That’s why we design, manufacture and install most products ourselves in our own factory in Zaandam, choosing materials and design constructions which result in high-quality products.

Seijsener products can be found in marinas all over the world: from Norway to Gibraltar, and from the Caribbean Sea to the Middle East.


Every marina can have an individual look with the wide range of service pedestals from Seijsener. Guests and visitors at your marina expect easy use of all the available facilities, and you, as the manager, would rather not have to worry about installations and maintenance. At Seijsener we’ve developed a range of high-quality service pedestals that meet every expectation; produced according to your taste, wishes and specifications.

Harbour in

Harbour In is a patented system developed by Seijsener. It’s a simple concept: we mount all marina connections in the jetty deck instead of on top. So not only the sockets disappear in the jetty deck, but the water tap can also be found close to every berth, and even the distribution cabinets for electricity, complete with circuit breakers and kwh meters, are concealed under an easy to open hatch. The result? High-level facilities and a tidy jetty. With Harbour In you’re choosing an ‘invisible pedestal’ that your guests will only notice when they need it.

Infrabox Houseboats

The Infrabox is the answer for those who want residential comfort in their houseboat. This type of ship with residential home facilities requires special connections that should be almost invisible due to long-term residence, but also easy to (dis)connect if you want to sail. That’s why Seijsener came up with the Infrabox. Underneath a beautiful stainless steel cover are three connections with quick couplings attached: two for the supply of electricity and water and one for the discharge of waste water. And connections, cables and pipes are concealed under the jetty deck.
