Offshore Direct Current (DC) collector grids are a promising technology for decreasing the installation and operation costs of offshore wind parks. Nevertheless, stability properties hence design such DC is not common or standardised. Hence, this paper describes an attempt to fill these gaps by analysing two different types grids—star string—by considering identical operating conditions. The ap...

Offshore wind-turbine support structures are largely made of steel since monopiles have accounted for the majority installations in last decade. As turbines become bigger, led to an exponential increase material and installation costs. From this point view, use concrete future has been initiated. In study, concrete–steel composite piles investigated. A pre-tensioned high strength pile was place...

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 material and structural thermal deformation characteristics of a steel stiffened panel under various fire-extinguishing methods were investigated experimentally. Propane gas was used to generate jet fires for panels widely as offshore installation structures. the initial imperfection (initial deflection residual stress) occurring during fabrication measured analyzed before after fire experi...

Offshore wind is a key part of the change toward renewable energy sources. farm developments are moving to sites that characterized by increased water depths and layered soil profiles, e.g., in North Sea. Suction caisson–based jacked structures expected be increasingly used support turbines at such sites. Experience suction caissons serving as foundations for offshore limited. The mechanisms go...

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...
