STORAGE TANK SOLUTIONS

Custom Tank Design & Engineering

 We specialize in the design of purpose-built storage tanks engineered to meet precise client specifications. Our team collaborates closely with stakeholders to ensure every tank system is optimized for site-specific conditions, operational performance, regulatory compliance, and long-term safety. Whether for hydrocarbons, chemicals, or renewable energy applications, our design methodology incorporates structural integrity, corrosion resistance, and lifecycle cost-efficiency.


Full-Scale Fabrication & Installation

 HexaHessman delivers end-to-end fabrication services using advanced welding systems, precision-cutting technology, and premium-grade materials. All fabrication work is subjected to strict QA/QC protocols and international standards such as API 650, ASME, and EN codes. Our site teams manage the full installation process—from logistics to final commissioning—ensuring flawless execution and minimal operational disruption. 

Refurbishment & Maintenance

 We provide comprehensive tank refurbishment and maintenance services designed to extend asset life and improve performance. Services include structural repairs, lining replacement, retrofitting, cleaning, testing, and compliance inspections. Whether for periodic maintenance or emergency restoration, our team ensures that your systems remain operational, safe, and compliant with evolving industry regulations.
