Looks like Babcock are trying to get out of offshore crew change. From their results yesterday:
This process will continue in the second half of this year, where we expect to exit our powerlines business in South Africa. We will also reshape our oil and gas crew change business to improve performance while ensuring we meet customer needs. We will provide an update on these activities with the announcement of our half year results in November.
The call transcript had the CEO saying it was still profitable for them but they are clearly looking to sell. Note nothing was said about the onshore EMS business.
