Deltamarin receives ABS AiP for versatile FPSO hull design
December 3rd, 2025 – Deltamarin and China Merchants Heavy Industry (CMHI) have received Approval in Principle (AiP) from the classification society ABS for a new versatile Floating Production Storage and Offloading (FPSO) hull design. The AiP certificate was awarded on December 3, 2025, at Marintec China in Shanghai.
The AiP for the versatile FPSO recognizes the feasibility of a robust, fatigue-friendly FPSO hull optimized for multiple field locations, including deepwater operations west of Africa. The vessel features:
| Length Overall | 285.10 m |
| Breadth | 60.97 m |
| Depth | 29.30 m |
| Maximum Draft | ~19.60 m |
| Crude Oil Storage Capacity | 1.5 MMBBL |
| Tank Arrangement | 5 x 3 configuration |
| Hull Shape | Barge with double bottom & side |
| Topside Capacity | 25,000 MT |
| Mooring System | Spread moored 4 x 4 configuration |
| Riser Balcony | 60-bay |
| Design Life | 30 years |

Using Deltamarin’s in-house tools, the main dimensions of the FPSO hull were optimized for minimum weight with only a few key inputs and constraints. Two additional hull variants (1.0 and 2.0 MMBBL) were also developed using our parametric hull model in a fraction of the time traditionally required for resizing of the FPSO hull.
The structural design of the FPSO hull is benchmarked against rule loads, enabling the concept to be utilized in different locations around the globe. Depending on the site conditions, the structural design can be further optimized for reduced steel weight, directly translating into lower CAPEX.
Together with CMHI, standardized design solutions have already been developed to ensure fast and efficient project execution during the EPC phase.

“The target of this project was to create a versatile FPSO hull with simple, robust marine systems and fatigue-friendly structural details,” said Toni Salminen, project manager at Deltamarin. “Our approach allows for tailor-made FPSO designs in a short timeframe, optimized for different locations and operational conditions worldwide.”
