Repair and Maintenance

Repair, Maintenance and Conversions

Year-round capabilities to service routine or emergency commercial and maritime shipping needs, as well as the annual lay-up and repair work on vessels of the Great Lakes fleet.

Repair and Maintenance

Our repair and maintenance professionals are among the industry’s most experienced and operate a year-round service at our Fincantieri Bay Shipbuilding facility in Sturgeon Bay, Wis.

Repair services include:
