Commercial Marine Sealing Solutions for Sealing Ships

At Sea in a Safe Harbour

The requirements for performance and reliability are even higher at sea than on land. This suits the technological competence of Freudenberg Sealing Technologies just fine.

Today, around 15,000 large merchant vessels, cruise liners and icebreakers set sail with seals from Freudenberg Sealing Technologies. We provide complete solutions for drive and steering systems (e.g. engines, thrusters, rudder systems, stabilizers, and more) from a single source and put together sealing packages that are optimally matched in terms of materials and functionality. In many cases, customer-specific special solutions in special sealing materials and large dimensions are needed.

Extremely long maintenance intervals are essential for the economically efficient operation of “floating buildings”. This is where Freudenberg products stand out due to their durability and first-class quality, for more than forty years.

Full Speed Ahead Towards the Future

In shipping, too, the wind is turning in the direction of environmentally friendly, emission-free propulsion systems. Quiet, clean, sustainable and efficient is the maxim on the open sea and in ports around the globe.

The first step is to introduce methanol as a maritime fuel. Freudenberg Sealing Technologies even goes a few steps further and equips vessels with modular, individually configurable battery and fuel cell systems. As the supreme discipline, we offer shipbuilders and shipping companies integrated hybrid drive solutions that ideally combine the advantages of batteries and fuel cells.

Go Green

Freudenberg Sealing Technologies has the appropriate (material) answers to the Vessel General Permit (VGP) of the United States Environmental Protection Agency (EPA). When it comes to media resistance to Environmentally Acceptable Lubricants (EAL), shipbuilders and shipowners are on the safe side with Freudenberg seals. Details on the behavior of common FKM materials with environmentally friendly lubricating oils and greases can be found here.
