Every shell door is engineered to your hull and measured in full 3D before it leaves Stralsund — so it welds in clean, on schedule, with no rework on the slipway.
01 — who we are
one partner for the entire opening — from raw plate to open sea.
At OMS — Ostsee Marine Solutions — we manufacture complete building packages, shell doors and marine components.
The entire supply chain stays in-house: engineering, 3-D cold forming, welding, system integration. Together with our sister company Ostseestaal, we even deliver complete hull sections with the shell doors already integrated.
In steel, stainless steel, aluminium or special alloys. No interfaces to coordinate, no supplier chain to manage.
