Mareal specializes in the structural design and analysis of fixed offshore structures, delivering robust and tailored solutions for the most demanding marine environments. Whether designing jackets for offshore substations or platforms for oil and gas facilities, our team combines decades of experience with cutting-edge simulation tools to deliver structures that meet the highest standards of safety, durability, and compliance.

Our expertise spans the entire design lifecycle—from conceptual studies to detailed execution plans—ensuring that every structure is engineered to withstand harsh offshore conditions while optimizing cost, weight, and long-term performance.

Key Services

• Lifting and Transportation Studies: Design and verification of safe handling methods for large offshore components during transport and installation phases.
• Structural Design Verification: Review and validation of structural concepts to ensure compliance with international codes (ISO, API, DNV) and project-specific criteria.
• Finite Element Modeling and Analysis: Use of advanced simulation tools to assess global and local behavior of complex offshore structures under static and dynamic loads.
• Buckling and Stability Studies: Identification and mitigation of structural instabilities, including global and local buckling risks in tubular and plated elements.
• Ship Impact and Collision-Friendly Analysis: Evaluation of accidental scenarios (vessel collision, dropped objects) and integration of energy-absorbing features to limit structural damage.
• Dynamic and Fatigue Analysis: Assessment of fatigue life under cyclic environmental loading (waves, wind, current) to prevent long-term degradation.
• Seismic Assessment: Evaluation of structural behavior under earthquake loading, in line with applicable seismic codes and site-specific requirements.

Additional Capabilities

• Global and Local Load Assessments: Evaluating the interaction of environmental and operational forces on structures to optimize performance.
• Optimization Services: Identifying opportunities for weight reduction and material efficiency without compromising safety or functionality.
• Software Expertise: In-house modeling and simulation using SACS, ABAQUS, and TEKLA, enabling integration from 3D modeling to code-checking and fatigue assessment.
