The Annamaria B Platform represents a significant offshore engineering achievement in the Italian sector of the Adriatic Sea. Commissioned by ENI and delivered through SAIPEM Energy Service, this project showcases TECON’s expertise in comprehensive offshore platform design and engineering. The platform serves the Annamaria field, providing essential living quarters and operational facilities for offshore personnel in challenging marine conditions.
Located in 59 meters of water depth, the platform required sophisticated engineering solutions to ensure structural integrity, safety, and operational efficiency. The project demanded careful consideration of environmental factors including wave action, wind loads, and the corrosive marine environment typical of the Adriatic Sea. TECON’s role encompassed the complete detailed design of the jacket foundation, topside deck structures, and integrated living quarters, ensuring compliance with stringent international standards.
TECON delivered a comprehensive detailed design package covering all major structural components of the Annamaria B Platform. The scope encompassed both primary and secondary structures, ensuring that every element met the rigorous requirements of offshore operations while providing safe and comfortable accommodations for the 19-person crew.
All design work was executed in strict accordance with industry-leading codes and standards, specifically the American Institute of Steel Construction (AISC) and API RP 2A-WSD (Working Stress Design) specifications. TECON’s engineering team performed comprehensive analyses for both in-service operational conditions and temporary installation phases, ensuring structural reliability throughout the platform’s lifecycle.
The design process incorporated advanced finite element analysis, environmental load modeling, and fatigue assessment to validate structural performance under extreme conditions. Special attention was given to the integration of living quarters with the operational deck, ensuring vibration isolation, noise control, and crew comfort while maintaining structural efficiency. The corrugated plate construction method was selected to optimize weight distribution while providing superior strength characteristics for the accommodation modules.
TECON’s multidisciplinary approach coordinated structural, mechanical, and safety engineering disciplines to deliver an integrated platform design that meets operational requirements while exceeding safety standards. The project was completed on schedule during 2007-2008, demonstrating TECON’s capability to deliver complex offshore projects within demanding timeframes.
