about us
A shell door specialist on a shipbuilding site.
Shell doors and hatches for shipyards worldwide since 2008 – built in Stralsund, side by side with Ostseestaal and Ampereship.
the group
three companies. one group behind every door.
Each with its own strength:
- Ostseestaal – since 1996, around 200 employees. Cuts, forms and assembles steel, up to complete vessel sections.
- Ampereship – builds and equips electric vessels, and converts existing ones from fuel to electric drive.
- OMS – builds the doors and hatches, from engineering to commissioning, all in-house.
For your yard: the door and the hull section around it – planned together, delivered as one.

vision & mission
the door should be the easy part.
Our vision: shipyards stop treating shell doors as a risk – because the door arrives complete, fits the first time and simply works for the life of the ship.
Our mission: to be an internationally competitive partner that saves your yard time and money – with complete door and hatch systems from one source, delivered on time and without warranty claims to date.
what we believe
no ship should wait for its doors.
On any yard, for any vessel, anywhere in the world.
who we build for
three markets. one way of building.
super- & megayachts
From sea terraces to balconies – for yards such as Abeking & Rasmussen, Lürssen and Dörries Yachts.
naval vessels
Tender doors, stealth doors and helicopter hangar doors – designed and tested to class standards.
special vessels
Doors and hatches for government, research and offshore vessels – and for cruise ships.
our path
grown with every project.
OMS started with single shell doors. Over the years, this has grown into complete systems: door, frame, hydraulics and controls as one module – measured in 3-D and tested before it leaves our hall, then installed at your yard by our own team.
Built in Stralsund. Fitted worldwide.
