Ship Fabrication and Ship Repair Equipment

The shipbuilding industry consists of tankers, aircraft carriers, patrol boats, luxury liners, barges, tugs, large seagoing vessels for containers and other cargo.

The experts at KOIKE have worked for decades with top companies in the area of shipbuilding. Our combination of products and know-how allow our customers to stay ahead of the competition. In particular, our group of KOIKE companies have designed specialized equipment to meet the needs of our customers. The types of cutting and welding done in shipbuilding require unique solutions for each application. Customers in this business segment require high up time and short turnaround time. Equipment made in this segment is often very large and requires high production. The large ranges of KOIKE standard and customized equipment are designed to meet the most rigorous demands of our customers.

Cutting machines, such as laser, plasma, oxy-fuel and waterjet cutting, are used to cut parts for stiffener plates, manholes, hatches, drains, the skin of the vessel, the skeleton, block parts, and pipes.  Our products range from small, one torch cutting machines, to large CNC gantry cutting machines with multiple torches.  Parts are often made of very thick steel and require specialized bevels for welding in the next stage of fabrication. Large gantry cutting machines have the option to add plasma bevel cutting and oxy-fuel bevel cutting to the machine. Laser and waterjet cutting machines can be equipped with three-dimensional bevel cutting heads.

Portable semi-automated cutting and welding equipment is employed in difficult areas often done by hand.  Productivity in these areas can often be increased by three-fold.

The handling of large weldments and parts can be done safely by the use of positioning equipment, such as gear driven positioners, headstock and tailstock sets, and turning rolls. Positioners reduce workload on overhead cranes and other handling equipment. Welds are done more efficiently and defects are reduced. Savings can also be seen in the reduction of wire and gas usage.
