Shipbuilding

Ship structural frames are formed by bending bulb flats and supporting profiles, essential stiffening components of the hull. In shipbuilding, these profiles are valued for their high strength-to-weight ratio.

Accurate profile bending is critical to ensure correct assembly, alignment and dimensional consistency of the hull structure, reducing the need for rework during welding and installation.

Faccin solutions cover the bending of a wide range of shipbuilding profiles, including HP profiles, flat bulbs, twin bulbs, T-bars, T-sections, flat bars, I-profiles, and equal or unequal angle profiles.

Press forming is used in commercial and defense shipbuilding to shape marine plates into complex geometries that cannot be achieved by standard rolling alone. Through localized and progressive deformation, hull plates, conical sections and spherical segments are formed with controlled accuracy and structural consistency.

This process is essential when working with high-resistance materials, especially for demanding applications such as navy ships and submarines, where tight geometrical tolerances are required.

Faccin press forming solutions support the production of double-curved hull plates, conical sections, spherical segments and cargo tank components for LNG/LPG vessels, ensuring controlled deformation, high forming force and reliable repeatability in demanding shipbuilding applications.

Plate levelling is a critical process in shipbuilding to ensure that marine plates are flat and free from excessive residual stresses before cutting, welding and forming operations. Through controlled plastic deformation, flatness deviations are progressively corrected across the plate thickness, improving dimensional accuracy and material stability.

This process is especially important when working with marine-grade steels, high-strength materials, and low-temperature steels application.

Plate rolling is a key process in shipbuilding for forming large marine plates into cylindrical and conical geometries used in hull shell sections, pressure hull components, tank segments and propulsion structures.

Precise control of curvature over long plate lengths is essential to ensure geometrical accuracy, proper fit-up during block assembly and consistent welding quality. This is especially critical when working with high-strength steels, low-temperature steels, thick plates and large-diameter shells, where repeatability and controlled deformation directly affect the quality of the final structure.

Faccin plate rolling solutions support the production of hull shell sections, submarine and navy ship components, LNG/LPG tank segments, oil tanker structures and azipod housings, combining high rolling force, accurate roll movement and advanced handling systems for stable and repeatable forming cycles.
