TCG Koçhisar (P-1221)
Block fabrication and erection works for Turkish Naval Forces under ASFAT.
TCG Koçhisar (P-1221) is one of the strategic naval platforms of our defence industry; on this project CMS AS took on critical steel fabrication and assembly work at ASFAT. From cutting and welding to outfitting and surface treatment, CMS AS delivered an integrated, single-source solution for the project. The zero-defect mindset expected in naval shipbuilding was reflected in every step of production.
Scope of Work
The principal works carried out by CMS AS on this project:
- Block Fabrication: Fabrication of ship blocks through CNC cutting and forming of steel plate and panel-line assembly.
- Erection & Assembly: Erection of the fabricated blocks — alignment and joining on the slipway/dock and application of seam welds.
Engineering & Execution
Approved production drawings and cutting plans were prepared before fabrication, and material traceability, dimensional control and weld inspections were recorded throughout the process. The traceability and quality-documentation requirements specific to naval projects were fully met. Critical joints were verified by non-destructive testing (NDT) and dimensional deviations were kept within tolerance.
Standards & Quality Assurance
Every stage was carried out under the CMS AS quality-management system and the supervision of the relevant class society. Welding was performed to WPS/WPQR-approved procedures and verified by NDT (UT/RT and visual inspection).
As a result, CMS AS served as a reliable supply partner in producing a platform that contributes to our national defence capability. The project was thus supported on schedule and to defence-industry quality expectations. The experience CMS AS has accumulated in shipbuilding and industrial steel since 1990 makes it a trusted solution partner for shipyards.
