Unusually for UK Regulations, the AaW Regs 2002 do not include the normal exclusions for the application of the Regs in Reg 1 - Application & Citation, nor in Reg 2 - Interpretation.

You have to look to Reg 26 [see below] to identify what work situations the AaW Regs apply to.

The normal limits of application under the HSWA specifically exclude ships & similar vessels except when being worked other than as a ship [for instance, berthed and non-crew members working aboard], in the absence of the normal exclusions, I would suggest that the AaW Regs were not intended to apply to ships etc when outside UK national waters rather than the wider remit of all ships etc.

I shall be happy for a more knowlewdgable person to address any inaccurracies.

AaW - Extension outside Great Britain
26. These Regulations shall apply to any work outside Great Britain to which sections 1 to 59 and 80 to 82 of the Health and Safety at Work etc. Act 1974 apply by virtue of the Health and Safety at Work etc. Act 1974 (Application Outside Great Britain) Order 2001[10] as they apply to work in Great Britain.
