Japanese offshore specialist Modec and Toyo Engineering have received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for their groundbreaking blue ammonia floating production, storage, and offloading (FPSO) vessel design.
Key Highlights
• The blue ammonia FPSO will produce ammonia from associated gas supplied by nearby oil and gas FPSOs.
• Innovative Approach: Instead of re-injecting associated gas into reservoirs (a common practice), the system will convert it into blue ammonia.
• Sustainability Impact: This concept aligns with global carbon reduction and energy transition initiatives by repurposing associated gas that would otherwise go unused.
Modec’s Vision
“This blue ammonia FPSO is intended to produce and store blue ammonia by using associated gas, which has conventionally been re-injected into the reservoir without specific applications.”
Industry Significance
• Enhances Offshore Decarbonization: Helps reduce flaring and CO₂ emissions while producing low-carbon ammonia.
• Expands FPSO Applications: Introduces a new monetization strategy for associated gas in offshore production.
• Supports Clean Energy Growth: Blue ammonia is seen as a key fuel in the transition toward low-carbon energy solutions.
Next Steps
• Further technical validation and pilot projects may be pursued before commercialization.
• Potential integration into existing FPSO operations to maximize efficiency.
