WP12G – Changements causés par l’emplacement du propulseur
XXX 327 XX has alleged that, due to the site relocation, a berm was introduced to mitigate accidental
release of a ‘pig’ or hydrocarbons under pressure from the 'pig launcher' (or 'pig receiver') enclosure. XXX maintains that this safety risk was just as applicable

the Original Site as part of design development.
