You seem to have assumed it would be in UK / EU / JARLAND.
Is this a wind up or just being a "troll" for someone with a commercial interest?
RVDT - My point (As a current offshore Pilot but also HCA qualified deck inspector - unpaid!) is that it should not matter where the vessel or rig or platform is registered or operated.
Any Operator should inspect a facility with SAFETY OF OPERATIONS as the primary concern - not "What can we get away with?" We are not being paid to put ourselves or our passengers in harms way.
CAP 437 which is generally regarded as the best written set of standards available is merely a better explained version of ICAO Annexe 14 Part 2 which recommends standards for all ICAO Contracting States which covers a pretty big part of the globe.
The system in the USA (Non ICAO) has been historically to operate to API (American Petroleum Industry) guidelines. The unfortunate result of this was a rash of helidecks especially on run down "Mom & Pop" platforms but even on locations owned and operated by the "Majors" which were built or maintained to the absolute minimum specs that the person picking up the tab could "get away with"
These specs were so far below the
minimum standard recommended by ICAO that it was hardly a surprise that helicopters came into contact with obstructions on or adjacent to helidecks.
The API standard is being superseded even in the US by more stringent requirements which is a trend that I am suggesting should be supported by us no matter how few regulations exist wherever we are working.
