Really do it the old fashioned way.
Put her in , use jacking bolts to ,lift and push, shim the feet and use feeler gauges for the coupling.
Had her lined up in approx 3 hrs after we started. ran nice and cool on trial with with shaft gland nipped up and minimal water ingress (Gortex packing).
making boat dollars as we speak so I can complete the job over the next couple of leave breaks.
On an interesting vessel at the moment, standard 60 mtr Anchor Handler but we have fitted 4 x 20 tonne / hour water makers on the make deck.
Our job is just to sail around making water and then discharge it into a barge that takes it down to barroe Is a big gas project (Class A nature reserve)
2 barges on line one discharging down at the island and one being filled by us about 30 miles away.
keeps me out of trouble until next week.
next vessel is a 83 mtr DSV (Dive support vessel)
