Extended technical guide for harbour electrical engineers, crane OEMs, terminal procurement teams, and festoon/reeling system designers specifying round crane cables for marine service. Covers: the engineering rationale for marine-grade round festoon cable specification (why the RHEYFIRM®(SI) NTMCGCWOEUS platform degrades prematurely in tropical C5-M environments); detailed layer-by-layer deconstruction of FC-HFX-RND™ construction; the NTMCGCWOEUS designation decoded (material identity, construction standard, and design-era limitations); the critical role of round-cable sheath uniformity in chloride barrier performance and how RHEYFIRM®(SI)'s standard polychloroprene compound underperforms against FC-CSR™ enhanced chemistry; slip-ring contact corrosion in motorised reeling variants; festoon trolley lateral loading and sheath abrasion mechanisms; ISO 9227 salt spray and IEC 60068-2-52 cyclic salt mist testing methodology; comparative evaluation across 24 critical performance parameters; and practical specification, procurement, and lifetime cost analysis frameworks for port operators evaluating FC-HFX-RND™ as a direct replacement for RHEYFIRM®(SI) NTMCGCWOEUS round crane cables.

RHEYFIRM®(RTS) (N)TSCGEWTOEUS OF encodes the cable's entire construction in German VDE convention. N — Normenleitung (standard cable). T — Trommelleitung (drum/reeling cable). S — Starkstrom (power current). C — Geschirmte Adern (screened cores, i.e., semi-conductive layers). G — Gummi-Isolation (rubber insulation). E — EPDM-based insulation compound. W — Wellenschlag (anti-torsion, wave-lay construction). T — Tragfähig (load-bearing, i.e., reinforced with high-tensile braid). O — Ohne Metallmantel (without metallic sheath). E — Elastomer-Außenmantel (elastomer outer sheath). U — Unbewehrt (unarmoured). S — Schlagwetterfest (resistant to explosive atmospheres/heavy-duty). OF — Öl- und Flammwidrig (oil- and flame-resistant enhanced). RTS — Rheyfirm Torsion Spezial (ultra-fine stranding optimised for torsion and high-speed reeling). Each element of this designation corresponds to a specific construction layer examined in the following sections.
