Ironhead Marine (Dry (Graving) Dock) and Fabricating in Toledo, OH

Bird's Eye View
While researching a flour mill in Toledo, I noticed a couple of dry docks, one of which has a couple of travelling gantry cranes. This is the High Bay facility of Ironhead Marine and Fabricating. It has:
  • Graving Dock #1 805'
  • Graving Dock #2 550'
  • 20,000 sq/ft (50' under hook)
  • 2, 20 ton cranes 
The Port Shop facility is further downstream and appears to be just a fabrication building.
  • 32,000 sq/ft (24' under hook)
  • 2, 10 ton cranes
  • 1, 20 ton crane
  • 2, 25 ton cranes
Ironhead has operated the Toledo Shipyard since 2006 and the services include:
  • Ship repairs, modifications and construction
  • Hull repairs
  • Machinery repairs
  • Fabrication and welding
  • Blasting and painting
  • Modifications and construction
  • Electrical and controls
  • Assembly
  • Plate rolls
  • High definition plasma and oxy-fuel cutting table
  • Saw cutting to 24 feet
  • Ironworker and punch
  • 50+ welding machines
  • Welding services – AWS and ABS Certifications

Since Ironhead needed heavy fabrication equipment and experts such as welders to make replacement parts for ship repairs, they fabricate equipment for other companies to keep their fabrication resources busy. It appears the fabrication business grew so that they needed a second building (Port Shop).

Their photo gallery provides a glimpse into the kind of work they do. I include a couple of examples.

The first stop on our trip after the Valor was M/V Great Republic, who is currently spending time in dry dock during winter layup. 
It always amazes me they are able to line up blocks, float the ship in and drain the dock down to settle the ship on top of said blocks.  
More to come!
Ronnie Barnes: The great republics design is incredible. A vessel designed to be able to navigate a river as fast as possible. Pilot house as far back as possible for maximum visibility. I will say I do prefer her name "American Republic" when she was owned by ASC, but i can appreciate Great Republic, because they kept it similar to what it was.
Kurtis Graham: It's actually kind of simple. They lay out a block plan based on the hull shape. They know exactly where to locate the ship on the flooded drydock and slowly drain the water. Usually when they get close to setting on the blocks, divers will check to see if it's lined up, but they know just where to position the vessel.
