Construction and fitting

Fitting the duct to the ship in dock takes only a few days and can be done during a routine dry docking period.

Alternations of stern tube bearing and shaft alignment from welding can be avoided or kept to an ignorable minimum by good workmanship and by welding the rings on both sides concurrently. Material used in the construction is normal shipbuilding steel.
