That figure of 500 for Babcock is for UK Offshore, Denmark and Australia Offshore. No word on whether Australia Onshore is included in the sale.
For UK based staff, at the end of the 2020 financial year - Babcock UK offshore had 363 staff, of which 37 were non-operational (Management, support, admin) and at the time they were operating circa 14 aircraft. Looking at CHC Scotia figures for FY20 a total of 325 staff with 95 non-operational. Average cost per head for CHC Scotia was £94,000 compared with £74,000 for Babcock UK Offshore.
Comparisons of 'costs of sales' for FY20, Babcock's UK offshore operation 'costs of sales' was £90 million against a revenue of £102 million and CHC Scotia 'cost of sales' was £134 million against revenues of £122 million.
CHC LLC has a huge opportunity to drastically reduce the cost base for their UK operation. Maybe merge the existing UK operations into a new entity called CHC Lite™?
