Offshore Cable Ladder Seawater Resistant 200mm-700mm Width Pickled Passivated

Offshore Cable Ladder Seawater Resistant is specified for platforms, rigs, FPSO modules and coastal terminals, where the cable route is exposed to continuous salt laden spray, high humidity and mechanical vibration, and where maintenance access is measured in crane lifts and shutdown windows.

The ladder is built in 316L stainless steel as the offshore default, with aluminum 6063 and hot dip galvanized steel options where weight or cost governs. Widths of 200 mm to 700 mm, rail heights of 100 mm to 150 mm and rung pitch of 225 mm or 300 mm cover the cable bundles found on a typical module, in 2 m and 3 m modules that pass through a deck hatch.

Seawater resistance comes from material selection and detail design together. Type 316L with molybdenum resists pitting and crevice corrosion in chlorides, all fasteners are A4-70 stainless so no galvanic couple is created, and every weld is pickled and passivated so the chromium oxide film is restored where heat has depleted it.

Offshore routes also require restraint: cables are clamped at short intervals for vibration and dynamic loading, and the ladder is fixed to the structure with brackets designed for the accelerations in the design case. Standard bends, tees and reducers let the route follow a congested module without field welding or hot work permits.

BENDIN produces offshore grade ladder at 7000 m per working day with 180 staff and thirty years of cable support engineering, exporting 60 to 70 percent of output to marine and energy contractors. Material certificates are traceable to the heat number, and every order is inspected for weld quality, straightness and fastener grade.

Minimum order 600 pcs, 25 working day delivery, 10 to 30 USD per piece, pallet packing with timber protection for sea freight, terms L/C, D/P or T/T. Send the module layout and the exposure class and we will confirm material grade, clamp spacing and the support bracket design.

BENDIN holds ISO 9001 quality certification and issues CE Declarations of Conformity. The standards above state the design and test basis of this product; third party test reports or national approvals are supplied on request and are not implied unless confirmed in the contract.

Dimensions, rung spacing and surface treatment are produced to project drawings. Load and deflection calculations are issued for spans above 3 m.

Q: How are the welds protected offshore?
A: Every weld is pickled and passivated so the chromium oxide film is restored where heat has depleted it, which is where pitting normally starts.

Q: Is the ladder designed for vibration?
A: Yes. Cable is clamped at short intervals and brackets are sized for the acceleration case, so the route stays tight under dynamic loading.

Q: Can the modules fit through a deck hatch?
A: Standard 2 m and 3 m modules are sized for manual handling and hatch access, and shorter sections can be produced for confined spaces.

Q: What is the minimum order?
A: Minimum order 600 pcs, delivery 25 working days, prices from 10 to 30 USD per piece.
