Weathertight & Watertight Doors

Weathertight & Watertight Doors

GOS supplies a full range of weathertight, splashtight, and watertight doors engineered for demanding marine and offshore service. Systems include hinged weathertight doors, QA (quick-acting) watertight doors, and sliding watertight doors for internal and external bulkheads, main decks, and below-deck watertight subdivisions. Each door is designed for a secure marine seal under static or dynamic pressure, in line with IMO, SOLAS and leading class rules.

​

Doors are manufactured in steel, stainless steel, aluminum, or GRP, with robust, heavy-duty construction, stainless moving parts, and robust gaskets for long-term performance in harsh environments. Units can be supplied as single or double leaf, with bolted or integrated mid-posts, 30 mm or 100 mm corner radii, and flat-bar, angle, or Z-frame coamings to match your structural design. Quick-acting, single-toggle, or wheel-operated closing systems are available, with typical configurations in 2, 4, or 6 dogging points depending on pressure and access requirements.

​

Standard and optional features include:

• Vision panels and portholes

• Certified fire and acoustic insulation packages

• Integrated locks, cylinders, keypads, and anti-piracy hardware

• Open/close indication, de-icing options, hooks, and door stoppers

Backed by over 35 years in marine supply, GOS delivers dimensioned, project-specific door packages with class approvals (e.g., USCG, ABS, DNV, BV, Lloyd’s) and documentation. Each door is supplied installation-ready to minimize fitting time, reduce re-work, and ensure compliance from first fit-up.
