Case study
Why an Offshore Platform Can't Run on Standard Power Cable
An offshore platform is a fundamentally different environment from an onshore installation, and it's why source generic industrial cable and hope it holds up isn't a real option for anyone specifying for one. Crew quarters, control rooms, and equipment spaces are enclosed and compact, with limited evacuation routes — so if a cable does burn, it cannot release the toxic, corrosive halogen gases and dense smoke that ordinary PVC-insulated cable produces. That single requirement is what separates a genuine offshore/marine cable supplier from a standard industrial one: a compliant halogen-free cable has to pass flame-retardance testing (cable groups under IEC 60332), low-smoke emission testing (IEC 61034), and low/zero-halogen acid-gas testing (IEC 60754) all at once, not just one of the three.
On deck and in machinery spaces, the same cable also has to tolerate constant salt spray, humidity, occasional oil contact, and the vibration and flexing that come with a structure that never sits still. This is exactly the gap the NEK 606 BFOU/RFOU family was written to close — a fixed-installation cable standard built specifically for offshore platforms, FPSOs and FSOs, drilling rigs, and packaged offshore equipment. RFOU covers the flame-retardant construction used for standard power, control, lighting and instrumentation circuits; BFOU adds a mica-based fire barrier on top of that for emergency and safety-critical circuits that have to keep working through a fire, not just resist starting one. This platform's order was RFOU throughout — flame-retardant and halogen-free, matched to lighting and general power distribution rather than the emergency-circuit duty BFOU is built for. TEBAOFLEX carries the same NEK 606 BFOU/RFOU construction across both its marine & offshore and oil & gas cable ranges, since a platform like this one sits at the intersection of both.

The Order: Four RFOU Sizes for One Platform
TEBAOFLEX supplied RFOU cable in four three-core sizes for this platform: 3×2.5 mm², 3×4 mm², 3×6 mm², and 3×25 mm². Built to the NEK 606 RFOU construction, each size uses tinned stranded copper conductors, EPR insulation, a halogen-free inner covering, and a tinned-copper-wire braid screen under an SHF2 halogen-free thermoset outer sheath — the layered, halogen-free build visible in both cross-sections above. That spread of sizes tracks how a platform's electrical load actually breaks down: smaller cross-sections like 3×2.5 mm² and 3×4 mm² are the range platforms typically run for lighting circuits, control panels, and small power outlets, while the heavier 3×6 mm² and 3×25 mm² sizes cover motor loads and larger power-distribution runs. Supplying all four from one manufacturer means the platform's electrical team works with a single consistent, compliant cable family — same construction standard, same halogen-free compound, same quality record across every reel — instead of reconciling test reports and lead times across four different suppliers for four different specs.

Built and Certified for Offshore Cable Supply
Supplying cable into an offshore project isn't only a manufacturing question — it's a paperwork and traceability question, since every reel needs test data a platform's engineering team can actually verify before it's approved for use. TEBAOFLEX manufactures under ISO 9001, ISO 14001, and ISO 45001 management systems, and its cable product lines carry UL/cUL, VDE, ICEA, KTL, and CE (LVD/EMC) certification across the company's range, giving international buyers a recognized compliance trail rather than a manufacturer's word alone. The company's underlying approach — see the duty before defining the cable — means a custom multi-size order like this one starts from the actual operating environment (offshore, halogen-free, multiple circuit types) rather than a catalog part number, with in-house lab verification behind the finished reels before they're ever loaded onto a truck.
For OEMs, EPC contractors, and procurement teams sourcing halogen-free marine cable, that combination — a certified RFOU cable manufacturer with in-house testing and custom multi-size production under one roof — is what turns a single project into a repeatable sourcing relationship rather than a one-off order.
From the Production Floor to the Platform Deck
Each size was wound onto its own reel on TEBAOFLEX's production floor, then packed and containerized for ocean freight. The delivery photos and video from this shipment are as real as the cable itself: TEBAOFLEX-branded wooden drums stacked and strapped inside an open shipping container, forklifted out at the receiving yard by crew in full PPE, with the site's storage tanks visible in the background.
That's not staged product photography — it's the actual unloading of this order, which is exactly the kind of first-party evidence that matters more than another spec sheet once a buyer already knows what RFOU cable is supposed to look like on paper. It's also a fair preview of what to expect sourcing from TEBAOFLEX more generally: reels leave the factory branded, labeled, and export-ready for exactly this kind of long-haul shipment, whether the destination is Guyana's offshore sector or another market entirely.

Results
The platform has the cable in service, and per the customer's own follow-up feedback, quality has been stable and the cable has supported the project well. It's a short, plain assessment rather than a quotable testimonial — and that's worth stating honestly rather than dressing it up as more than it is. For cable feeding an offshore platform, stable performance is precisely the outcome that matters.

Sourcing RFOU Cable for Your Offshore Project
If you're evaluating suppliers for RFOU cable or another halogen-free marine/offshore cable type, this order is a reasonable template for what to ask for: a manufacturer who will quote and produce your full range of sizes together, back every reel with certification and test data, and ship export-ready on a timeline that matches your project schedule — not just the cheapest single spec sheet in isolation. TEBAOFLEX works with OEMs, EPC contractors, and offshore project buyers on exactly that basis, whether the order is a single reel for a pilot installation or a full multi-size platform order like this one.

The Takeaway
Sourcing cable for an offshore platform isn't a job for a single spec sheet — most projects need a range of sizes covering lighting through heavier power circuits, all halogen-free and all built to the same offshore standard, ideally from one supplier who can produce, test, and ship the full range together. If you're specifying RFOU cable, or comparable halogen-free marine cable, for a platform, vessel, or other offshore installation, TEBAOFLEX can work through your circuit list and quote the full range with you before you order.
