Shipfitting | Structural

Shipfitters, a structural discipline, oversee the assembly and installation of vital ship components. Their expertise lies in working with metal and constructing essential elements like bulkheads and frames, ensuring the overall stability and integrity of the vessel.

Our shipfitters handle the maintenance, installation, modification, and repair of various interior and exterior components, including foundations, bulkheads, doors, decks, hatches, superstructure, tanks, sea chests, sponsons, and deck houses.

Equipped with skills in cutting (gas, arc, and shear), rolling, shaping, grinding, and fitting steel plates and shapes, our shipfitters ensure precision and efficiency in their work. They proficiently lay out and fabricate metal structural parts within the vessel’s hull, utilizing a range of specialized tools such as shears, punches, drill presses, bending rolls, bending slabs, furnaces, saws, and metal presses.

Additionally, they demonstrate expertise in Oxygen Acetylene cutting procedures and possess the ability to tack weld. Their typical tasks include preparing plates for shearing, planning and bench planning, handling angles for punching and shearing, creating collars and brackets for installation, and working on various other structural components. From installing deck ladders, fittings for riggings, and mooring equipment to handling fabrication tasks like plumbing transverse bulkheads and lifting shell frames from vessels, our shipfitters are skilled in a variety of essential operations.
