DOCUMENT CONTROL
Approval Scope, Documentation and Installation Guidance
Use public certificates, technical sheets and mounting instructions as controlled references—not blanket approval or fabrication authority.

DWTA60 document restricted to exact certified model and scope
Bofor marine closures, selected and supplied through ERBA Marine
ERBA Marine coordinates technical selection and supply for the agreed marine-door, hatch, custom-closure or component configuration. Included drawings, documents, delivery scope, service support and applicable warranty route are stated in ERBA Marine’s written quotation.
Identity and approval boundary: Bofor is the manufacturer of the referenced products. Approval is never inferred across the range. Classification, fire rating, pressure head, approved dimensions and installation conditions apply only to the exact model and current certificate scope.
SELECTION BEFORE SPECIFICATION
How to approach marine closure approvals & installation guidance
Published families and images help identify a starting point; verified vessel and closure data determine the final selection.
Marine Closure Approvals & Installation Guidance
The public document set contains mounting instructions, a cast-hatch welding procedure, four light-hatch reference sheets, a stopper installation sheet and the exact-scope DWTA60 RINA certificate. Historical CRS documents whose source validity ended on 5 June 2024 and all DWG files are deliberately excluded from public publication.
Before supply or installation, ERBA Marine confirms the current revision, continued validity, exact model, dimensions, materials, construction, fire rating or pressure limitations, installation conditions and class, flag or project-acceptance requirements in writing.
Information to confirm
- Exact model and complete suffix
- Document number, revision and stated validity
- Approved size, material and construction
- Fire rating, pressure or service limitation
- Welding, fastening, coaming and surrounding structure
- Class, flag, surveyor and project-specific acceptance
