Sound-Reducing Stainless Steel Wheelhouse Sliding Door | Manual Weathertight

Product Specification

Sound-Reducing Stainless Steel Wheelhouse Sliding Door | Manual Weathertight Marine Bridge Door (CBM 2055-82)

Product Overview

The CBM 2055-82 stainless steel wheelhouse sliding door is a manually operated external sliding door for bridge and wheelhouse openings in the vessel superstructure. Its sliding arrangement avoids the swing clearance required by a hinged door and is suitable where access space beside the wheelhouse is limited. The standard arrangement includes a door leaf, frame, window, lock, cover plate, upper track, roller assembly, lower guide track, buffer seat, stopper, insulation material, and sealing components.

This page focuses on the Type A stainless steel configuration, available as AL left-opening and AR right-opening versions. The door can be supplied to the standard nominal sizes or adapted to an approved vessel drawing. “Sound-reducing” describes the insulated leaf and sealed perimeter concept; a specific acoustic rating must not be stated unless the test method, target value, and report are confirmed. The product is specified as weathertight, not watertight, unless a separate approved design and test scope is agreed.

Quick Specifications

• Product type: manual wheelhouse sliding door → saves swing space at bridge and superstructure access openings.
• Standard configuration: CBM 2055-82 Type A stainless steel → AL for left-opening and AR for right-opening arrangements.
• Nominal opening range: 1700 × 750 to 1800 × 1000 mm → covers the four standard clear-opening combinations listed below.
• Frame depth: D = T + 50 mm → the ship-side lining thickness T must be confirmed before production.
• Door construction: insulated stainless steel leaf with window, track, rollers, guide, stop, lock, and sealing arrangement → supports low-noise manual travel and weather protection.
• Approximate Type A weight: 56 to 72 kg → relevant to installation handling, track support, and freight planning.
• Testing: hose test and/or air leakage test as applicable → method, acceptance criteria, and witnessing scope must follow the project specification.
• Security: anti-piracy closing or locking arrangement available by project → lock function must be coordinated with the vessel access-control and escape plan.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm CBM 2055-82 Type A and select AL left-opening or AR right-opening. Provide the vessel GA or a marked direction sketch to avoid handing errors.

Step 2: Confirm nominal opening L × B, steel wall cutout L1 × B1, door travel space, installation side, lining thickness T, and frame depth D. Check that the full door outline and track cover do not interfere with windows, consoles, handrails, or bridge-wing equipment.

Step 3: Confirm stainless steel grade, surface finish, window glass specification, insulation construction, gasket material, and any required acoustic target. A numerical sound-insulation value requires an agreed test and rating method.

Step 4: Confirm the closing and locking arrangement, including anti-piracy function, internal release, keying, access-control interface, and compatibility with the vessel escape plan.

Step 5: Confirm weathertight test method, air or hose test acceptance criteria, inspection witness, material traceability, maker certificate, and any classification-society approval scope before quotation.

Step 6: Provide quantity, vessel type, installation location, destination, required delivery time, approved drawing, wall construction details, and reference photos if available.

Installation, Acoustic & Quality Advantages

• The sliding travel path reduces the deck and interior clearance required for opening, which is useful at wheelhouse entrances with limited swing space.
• Correct upper-track straightness, roller alignment, and lower-guide positioning reduce running resistance, impact, and operating noise. Track distortion during shipyard installation can directly affect door movement.
• The insulated leaf and continuous perimeter sealing arrangement help limit airborne noise and weather leakage paths. Actual installed acoustic performance depends on the complete leaf, frame, glass, seals, lock engagement, and surrounding bulkhead construction.
• Stainless steel construction provides a corrosion-resistant exposed surface, but the exact grade, weld finishing, pickling/passivation, and treatment of interfaces with carbon steel or aluminium structures must be specified for the vessel.
• Weathertight performance depends on frame flatness, gasket continuity, closing-device engagement, lower-track drainage, and final installation accuracy; the door should not be described as watertight without separate evidence.
• The anti-piracy arrangement can strengthen controlled access to the wheelhouse, but it must be reviewed together with internal escape, emergency operation, and the vessel security plan.
• Window glazing, seal replacement access, roller maintenance, stop position, and removable cover plates should be checked at drawing approval to support inspection and future maintenance.

Custom Attributes

• Standard: CBM 2055-82 → standard basis for the wheelhouse sliding-door arrangement; the exact current ISO or class reference must be confirmed by project
• Product Focus: Type A stainless steel → AL is left-opening and AR is right-opening; Type B aluminium and Type C GRP are separate variants
• Nominal Opening: 1700 × 750 / 1700 × 900 / 1800 × 900 / 1800 × 1000 mm → select according to access requirement and vessel drawing
• Lining Thickness: T, buyer-selected → required to determine the frame depth and ship-side interface
• Frame Depth: D = T + 50 mm → coordinate with bulkhead lining and interior finishing
• Operation: Manual sliding → roller and track condition determine operating force and noise
• Weather Protection: Weathertight → hose or air test scope is according to project requirement; not a watertight claim
• Acoustic Performance: To be confirmed → state a dB or Rw value only when the assembly, test method, and report are available
• Locking: Anti-piracy arrangement available → confirm inside release, keying, access control, and escape-route compatibility
• Certificates: According to project requirement → type approval, MED applicability, class certificate, and witness inspection are not default unless agreed

How It Works

Pull the handle → Roller assembly moves the leaf along the upper track → Lower guide controls alignment → Buffer and stopper define the travel limit → Closing and locking device secures the leaf against the frame and maintains the specified seal contact

Applications

Wheelhouse external access | Navigation bridge entrances | Superstructure deckhouse openings | Merchant vessels | Passenger and cargo vessels | Workboats and service vessels | Newbuilding and replacement projects

FAQ

Q1: Is this door supplied with a guaranteed soundproof rating?

A1: No numerical acoustic rating is stated from the available data. The insulated leaf, glass, seals, frame, lock engagement, and ship-side installation all influence the result. Please provide the required dB or Rw target and accepted test method if a quantified rating is required.

Q2: How should left-opening and right-opening be confirmed?

A2: Select AL or AR only after the opening direction is marked on the GA or approval drawing. The drawing should show the viewing side, closed position, travel direction, and available track space; verbal descriptions alone can cause handing errors.

Q3: Are hose testing, class certificates, type approval, and EC MED approval supplied as standard?

A3: No. Hose or air testing, maker documentation, class witnessing, type approval, and EC MED applicability depend on the vessel, door function, contract specification, and approval scope. These requirements must be confirmed before quotation and production.
