Circular loop between NEC 555 and NFPA 307, suggestions??

[J-InTheJ-Box]

Hello my fellow electricals. In searching for information about supporting feeders (15kV) going from land to a stationary pier for vessels larger than 300 tons, the NEC section 555 directed me to lookup NFPA 307. When I look in the 307 document, its sole direction for electrical is to refer to the NEC. This circular loop is not very helpful and it sounds like somebody is playing the hot potato game of responsibility. Some useful information about wiring up a pier, for larger than 300 ton vessels, has to exist somewhere, otherwise cruise ships, tankers, cargo haulers, and any other large ship would be SOL. So, does anybody have any useful references for an existing pier being upgraded with new feeders or should I just treat the pier as a wet location and follow the rules as laid out by the NEC?

IMHO the background is that a floating vessel is not directly subject to the NEC and that might extend to some doubt about the feeder to the pier, so the reference in 555 and back to the NEC just serves to remove any doubt and leave the installation subject to all of the other "normal" considerations of the NEC.
