Offshore oil spills may pose a severe threat to marine ecological environment. In this paper, new methodology based on Bayesian network (BN) and Influence Diagram (ID) is developed for risk management emergency decision-making of spill accidents. The integrates before accident response after accident, which can balance cost, render an optimal decision-making. Marine scenarios including root cau...

This paper describes application areas for mobile service robots in offshore oil and gas producing environments, requirements and restrictions for the use of the robots together with a first prototype and its evaluation in a field test. The field of offshore oil and gas production is analyzed in the first part to identify possible application scenarios for mobile automation. It shows that there...

This paper examines liquidity premium focusing on the difference between offshore and onshore hedge funds. Due to tax provisions and regulatory concerns, offshore and onshore hedge funds have different legal structures, which lead to differences in share restrictions such as a lockup provision. We find that offshore investors collect higher illiquidity premium when their investment has the same...

the present sought to draw a comparison between model predictive control performance and two other controllers named simple pi and selective pi in controlling large-scale natural gas transport networks. a nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in simulink® environment of matlab®. control schemes were designed to provide a s...

This paper investigates the integrated riser/vessel system which is subjected to random waves. Riser pipelines are the main components of the oil and gas offshore platforms. Whereas Iran country has been located on the fringes of Caspian Sea deep water, therefore study and research in this area is increasingly essential. The fluctuation of floating production causes the severe response and grea...

This paper investigates the effect of moisture content on interface shear strength between offshore clay and steel plate. Although, sensitive and high plasticity offshore clay deposits are widely distributed in Malaysia and many other countries in the world, and steel is a vital construction material for many structures, research works on interaction between offshore clay and steel surface are ...

Global outsourcing – also known as offshore outsourcing -is generally dual sourcing involving both offshore and onshore activities because certain activities such as requirements analysis have to be performed onshore in consultation with users. The amount of onshore work or offshore work depends on the nature of IS being developed and vary among IS projects. Vendors charge higher hourly rate fo...

Wind energy has experienced dramatic growth over the past decade. A small fraction of this growth has occurred offshore, but as the best wind resources become developed onshore, there is increasing interest in the development of offshore winds. Like any form of power production, offshore wind energy has both positive and negative impacts. The potential negative impacts have stimulated a great d...
