How many companies are there globally involved in the design,
construction and transportation of offshore structures in each of the
following geographical regions aggregated by region?
1) Europe, Middle East and Africa (excluding UK and BeNeLux)
2) UK, BeNeLux and the Americas
3) Korea and Japan
4) Greater China (Including Australasia, Malaysia, India and SE Asia
generally but not Korea and Japan).
By offshore structures I mean fixed or floating structures used in the
drilling, exploration and production of oil and gas including but not
limited to: fixed platforms, semi submersibles, jack ups, drill ships
and Floating Production, Storage and Off-loading vessels (FPSOs).
I realise you will need to make certain assumptions to answer this,
like, for example, only consider organisations with more than 20
employees.  If you can get an answer only by making certain
assumptions I would still like to have the answer but with the
assumptions stated.  Companies can be whole companies or a subsidiary
of companies involved in the same field of work in the same region.
