• Learn about the materials, fabrication techniques, and construction processes used in offshore structure development.
• Gain insight into the inspection and maintenance processes critical to ensuring the safety and performance of offshore structures.
• Develop skills for identifying common failures and the most effective repair methods.
• Familiarize with industry standards and regulations that govern offshore structure design, construction, and maintenance.

Content

Day 1: Introduction to Offshore Structures

• Overview of offshore structures: Types, functions, and applications.
• Design considerations for offshore platforms: Environmental, economic, and safety factors.
• Key components: Substructures, topsides, floating units, and mooring systems.
• Types of offshore platforms: Fixed platforms, jack-up rigs, semi-submersibles, and floating production systems.
• Regulatory framework: Codes, standards (API, ISO), and industry practices.

Day 2: Design of Offshore Structures

• Structural design principles: Load analysis, stability, and material selection.
• Design challenges in offshore environments: Corrosion, fatigue, and wave loads.
• Site assessment: Soil conditions, water depth, and seismic activity.
• Computational tools and simulation techniques for offshore structure design.

Day 3: Construction of Offshore Structures

• Fabrication of offshore structures: Materials, welding, and construction processes.
• Offshore transportation and installation methods: Heavy lifting, floatover, and crane operations.
• Project management during construction: Timelines, budgets, and coordination with stakeholders.
• Safety considerations during construction: Risk management and hazard analysis.
• Challenges in offshore installation: Environmental factors, logistics, and weather.

Day 4: Inspection, Maintenance, and Monitoring of Offshore Structures

• Types of inspections: Visual, non-destructive testing (NDT), and structural health monitoring.
• Maintenance strategies: Preventive, corrective, and predictive maintenance.
• Monitoring techniques: Structural health monitoring (SHM), sensor systems, and data analysis.
• Common maintenance issues: Corrosion, wear, fatigue, and operational damage.
• International standards for offshore structure inspections and maintenance (e.g., ABS, DNV-GL, NACE).

Day 5: Repair of Offshore Structures and Life Extension

• Repair techniques for offshore structures: Welding, patching, reinforcement, and retrofitting.
• Strategies for life extension: Upgrading, refurbishing, and extending the service life of offshore platforms.
• Managing structural failures: Identifying causes, impact assessment, and remediation actions.
• Emergency response procedures for offshore structure damage.
• Decommissioning and disposal of offshore platforms: Environmental considerations and industry best practices.

NOTE:

Methodology

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. You will also be encouraged to raise your own questions and to share in the development of the right answers using your own analysis and experiences.  Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course.

Very useful Course Materials will be given.

• 30% Lectures
• 30% Workshops and work presentation
• 20% Group Work& Practical Exercises
• 20% Videos& General Discussions
