Type MC-HL Cable, Offshore installations

[Chan]

I was following this thread http://forums.mikeholt.com/showthread.php?t=58879

Where it was posted by rbalex that The "critical" element is the terminations - not the cable.
In what way?

I am aware of some offshore installations that use alot of none-textile hardening tape, such as denso, on cable entries into devices, lights is what way can this affect Class 1 Div 1 and @ installations other that the obvious prevention of breathing in the event the device is called upon to contain and explosion.


I am very curious to hear some opinions on these pictures attached some installations I came across that are similar to that I am dealing with. I am interested in finding out the violations to API RP 15 code and NFPA 70 as far as the visual on these pictures go....

Can the types of cable be determined to be Type MC-HL just by visual on these pictures

None of the cables in the photos are MC-HL; they appear to be cables consistent with IEC but not NEC Zone 1 or 2. IEC and NEC "Zones" are not entirely compatible.

Thanks for you observation will check into this, what can you tell me though about you opinion on the use of Non-hardening grease-bearing textile tape employed on device cable entries and around screwed device covers (as shown )

I'm not sure what it's intended purpose was, but it doesn't meet either NEC or IEC requirements for sealing.

I have also come to the conclusion that it did not meet the API or NFPA Standards for electrical installations in classified locations, not to sure why this was used but was very curious for a second opinion wrt to it it were best practice or common practice or other.
Thanks
