Recent years, offshore outsourcing has received large amount of attention from both industry and academia because of its attractive advantages such as cost reduction, talent access. As an alternative way to implement information systems in operation management, offshore insourcing has been greatly overlooked. Though organizations shun from the contractual obligations in offshore insourcing, the...

1.1 Offshore Structures: Offshore structures used for oil and gas extraction have the common function of providing a safe, dry working environment for the equipment and persons those operates the platform. Jacket supported drilling equipment as a guide for the piled foundations. The substructure referred to as the jacket is a three dimensional space frame made from large tubular steel members. ...

Offshore facilities are essential infrastructure systems for many nations because their partial or total interruption causes diverse consequences in the economic, political, environmental, and social sectors. With aim to preserve such structures at acceptable reliability levels, an approach is proposed calculate optimal instant of time which inspection maintenance works can be performed. The es...

This paper addresses a detailed analysis of the ice–structure interaction process phase-locked ice crushing (PLC) against offshore structures. Directly measured load, structure response data, and in situ observation from field measurements on Molikpaq lighthouse jacket platform were used study. summarizes new ductile damage-collapse (DDC) failure mechanism for PLC process. The DDC shows that is...

The scale of offshore wind turbines (OWTs) has increased in order to enhance their energy generation. However, strong aero/hydrodynamic loads can degrade the dynamic characteristics OWTs because they are installed on soft seabeds. This degradation shorten structural life system; repetitive lead seabed softening, reducing natural frequency structure close excitation frequency. Most previous stud...

Offshore wind farms with high installed capacities and located further from the shore are starting to be built by northern European countries. Furthermore, it is expected that by 2020, several dozens of large offshore wind farms will be built in the Baltic, Irish and North seas. These wind farms will be constituted of a considerable number of turbines packed together. Due to shadowing effects b...

PURPOSE: An analytical model to predict the response of mounds placed in the offshore is presented, with the overall aim of providing a technique for the preliminary design of mounds subjected mainly to cross-shore sediment-transport processes induced by non-breaking waves. For example, offshore mounds created from dredged material can be used to protect sandy beaches by dissipating wave energy...
