Common issues

• Note: the order data tags this as 'Marine Cables & Wiring' - the designations (1SN, 2SN, 1SC, 2SC) are standard hydraulic hose classifications (single/double wire-braid, compact spiral), so this is a hydraulic hose product line, not electrical cable. Content below covers hydraulic hose.
• External cover cracking, abrasion or ozone/UV degradation exposing the wire reinforcement
• Corrosion of the internal wire braid/spiral reinforcement hidden under an intact-looking cover
• Leakage at crimped end fittings from incorrect crimp diameter or fitting mismatch
• Hose failure/whip from exceeding minimum bend radius or from chafe against structure
• Kinking during installation reducing flow and weakening the hose wall
• Use of the hose beyond its calendar shelf-life/service-life regardless of visual condition

Inspection checklist

• Check the manufacture-date band/tag on each hose against the maker's or class shelf-life/service-life guidance
• Visually inspect the cover for cracking, blistering, abrasion or exposed reinforcement
• Inspect crimped fittings for leakage, corrosion or movement
• Check routing for chafe points, tight bends below minimum radius, and missing chafe guards/clamps
• Pressure-test any newly made-up hose assembly before entry into service
• For fire-resistant type hoses near hot surfaces (e.g. exhaust, steering gear), confirm correct type is fitted where required
• Check hose support clamps are intact and correctly spaced
• Review PMS records for hoses due for calendar-based replacement

Service intervals

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Critical spares

• Matching hose assemblies of the correct pressure class/DN size (1SN, 2SN, 1SC, 2SC or fire-resistant type as applicable)
• Correctly rated crimped end fittings
• Hose clamps and chafe guards
• Fire-resistant sleeving/wrap where required by the application

Safety

• High-pressure fluid injection injury from pinhole leaks - do not check leaks with bare hands
• Hose whip on sudden failure under pressure
• Hydraulic fluid fire risk where hoses run near hot surfaces - this is the reason fire-resistant types exist
• Stored energy release when disconnecting pressurised hoses - depressurise and isolate first

Class survey

Where these hoses are fitted in class-relevant systems near hot surfaces (steering gear, fuel lines, engine room), class/flag rules commonly require fire-resistant or fire-tested hose and calendar-based replacement records rather than condition alone - keep manufacture-date records and replacement history in the PMS for survey.
