An approval in principle (AIP) has been granted by ABS to Petrobras for an innovative "sandwich hull" design concept aimed at enhancing safety in floating production storage and offloading (FPSO) tanks. This design leverages a combination of longitudinal and transverse elements constructed from steel-concrete-steel sandwich structures, providing obstruction-free FPSO tanks.
This structural improvement is expected to enhance operational efficiency during tank inspections and accommodate the use of remotely operated tools and automated devices, including robotics.
Enhanced safety in operations
The design has undergone thorough evaluations by ABS, aligning with class requirements. Michael Kei, Vice President of Technology at ABS, emphasised the anticipated improvements, stating, "Tank cleanings and inspections are some of the most hazardous jobs for offshore personnel."
He adds, "This new design from Petrobras is expected to provide much safer operations by minimising the need for humans to enter the tanks. With internal tank surfaces free of obstacles, survey operations can be carried out using advanced technologies and robotic systems."
Adopting modern technologies for inspection
ABS has been at the forefront in adopting technologies, such as unmanned aerial vehicles (UAVs), crawlers, remotely operated vehicles (ROVs), and wearable technologies to enhance the effectiveness of traditional class-related surveys and inspections.
These advancements are geared towards reducing the reliance on human involvement for potentially risky operations, thereby increasing safety while maintaining efficiency.
