Cathay has 330-343's (B-HLM-W), which have 772B engines. The others, B-HLA-L & LAA-C, are A330-342s, which have the 772s. Internally in Cathay they are referred to as 333, if in a three class fit and 330, if in a two class fit. This where Silberfuchs got his 333 from.
They are all 180 ETOPS under Cathay's AOC, as pointed out by Spanners.
