FN Diving Performs Repairs on
Vessel’s Propeller (Sweden)
FN Diving was called upon to perform an inspection and eventual
repairs on a vessel’s propeller which encountered severe vibrations after
passing the thick ice on the Baltic sea. A team of FN Diving technicians was
deployed immediately and travelled the night with all necessary equipment to be
able to perform the repairs whilst the vessel was anchored in a Swedish fjord.
Arriving
early afternoon the following day the team loaded and installed the equipment
on a local workboat and sailed towards the vessel.

The
third blade was bend in a manner that made underwater cold straightening
possible with the cold static load press. Restoring the propellers efficiency
immediately.
A full
propeller polish was performed after completion of the damage treatment, in
order to provide a proper finish.
Afterwards
the vessel sailed without any vibrations or loss of the propeller’s efficiency
