The work related to sand-blasting and painting the hull and pipe-related as well as engine room-related work is routinely being performed as part of replacing the pipelines and repairing the pumps.
Do you find the sentence acceptable and understandable?
It's very long and particularly clunky at the beginning.
I would probably say something like:
Sand-blasting, hull-painting, pipe- and engine room-related works are being routinely performed during the replacement of the pipelines and the repairs to the pumps.
