This study extends the authors’ previous numerical and experimental studies simulating progressive collapse of steel stiffened-plate structures in fire events (Paik JK, Ryu MG, He KH, Lee DH, SY, Park DK, Thomas G. 2021a. Full-scale testing to stiffened plate under lateral patch loading (part 1) – without passive protection. Ships Offsh Struct. 16(3):227–242; Paik 2021b. 2) with 16(3):243–254; ...

The integrity of mooring chains is essential to the safety a range offshore platforms. However, line failures are occurring earlier than their design lives, with high number these due fatigue. Early in fatigue life component initiation processes occur, where hotspot sensitive mean load and there plastic strain accumulation from multiaxial stress-strain responses material, leading cyclic damage ...

Deepwater GWK-8 is a gas well in deep sea with 1500 meters water depth and deviated sandstone formation that has good permeability, potentially high-rate well, high reservoir pressures, large size. This expected to immediately ramp up production at optimal productivity through Floating Production Storage Offloading (FPSO) Makassar Strait. For deep-water exploration must be commercially viable, ...

This study presents a reanalysis of FPSO (Floating Production Storage & Offloading) CSM (Cidade de São Mateus) accident, occurred in February 2015, the post-salt Camarupim fields, Espírito Santo offshore area, using FRAM (Functional Resonance Analysis Method) methodology, and based on technical-scientific materials such as books, articles reports prepared by companies involved accident Braz...

At present, dry wellheads are usually adopted on small-storage TLP and SPAR platforms to develop offshore oil gas because of the robust hydrodynamic performance under severe-wind seas. On other hand, FPSO FDPSO that have a larger storage capacity can hardly use this cost-saving facility due their relatively poor vertical motion performance. Cylindrical FPSOs proposed improve heave ship-type FPS...

With rapid economic and demographic growth, traffic conditions in medium large cities are becoming extremely congested. Numerous metropolitan management organizations hope to promote the coordination of urban development by formulating improving strategies. The effectiveness these solutions depends largely on an accurate assessment distribution hotspots (centers activity). In recent years, many...

The prevailing offshore field development solutions, i.e., dry tree and wet systems, are confronted with serious technical economic challenges in deep ultra-deep waters resulting from the large depth of water, far distance, harsh ocean environmental conditions, as well high cost. In response to these challenges, an innovative Deepwater Artificial Seabed (DAS) production system is proposed this ...

Abstract. Gas flaring is a substantial global source of carbon emissions to atmosphere and targeted as route mitigating the oil gas sector footprint due waste resources involved. However, quantifying from resource-intensive, no studies have yet assessed for offshore regions. In this work, we present dioxide (CO2), methane (CH4), ethane (C2H6), NOx (nitrogen oxide) data 58 emission plumes identi...
