Most of the standards available for assessment failure pressure corroded pipelines are limited in their ability to assess complex loadings, and estimations conservative. To overcome this research gap, study employed an artificial neural network (ANN) model trained with data obtained using finite element method (FEM) develop equation predict a pipeline single corrosion defect. A analysis (FEA) m...

Nowadays with increasing production and exploration activities offshore, the FPSO system has been widely adopted globally because of its unique design adaptability to these offshore environmental conditions. This research project aims provide station-keeping characteristics an in West African region, by analysing spread mooring for multiple load cases, different offset, draught conditions loads...

Offshore wind turbines are now a mature technology to produce renewable energy on vast scale, nonetheless several design and maintenance planning challenges remain. There have been attempts investigate the impact of marine growth fixed offshore turbine structures, but only few adopted whole dynamics approach. This work presents methodology capture influence dynamic response tripod substructure,...

Abstract The Red Squirrel ammonia field experiments were conducted at the DNV Spadeadam site in UK 2022. Field test data currently exists for high‐pressure (ambient temperature) two‐phase releases of from Desert Tortoise (1983) and FLADIS (1996) experiments. No tests have ever been done cold (refrigerated) liquid spills on dry land or into water. handling liquified ammonia, during storage/proce...

This is the second part, after [1], of the research devoted to analysis of 1ports composed of similar conductors (“f-circuits”) described by the characteristic i = f(v) of a polynomial type. This analysis is performed by means of the power-law “αcircuits” introduced in [2], for which f(v) ~ v α . The f-circuits are constructed from the α-circuits of the same topology, with the proper α, so that...

This paper reports on experiences from using a UML-based method for trust analysis in an industrial project. The overall aim of the trust analysis method is to provide a sound basis for making trust policy decisions. The method makes use of UML sequence diagrams extended with constructs for probabilistic choice and subjective belief, as well as the capture of policy rules. The trust analysis me...

The non-linearities in waveand slamming-induced rigid-body motions and structural responses of ships such as heave, pitch and vertical bending moments are consistently investigated based on a rational timedomain strip method (Xia, Wang and Jensen, 1998). A hydrodynamic model for predicting sectional green water force is also outlined for the investigation of the effect of green water loads on t...

There is accelerating interest in composite risers for deepwater applications. Composite risers offer much higher strength to weight ratios over metallic risers but there is less experience of their behavior in deepwater environments. A general review on current developments specific to composite risers highlighting the remaining challenges and the applications, design evolution, state-of-the-a...
