The futures of offshoring FDI in high-tech sectors
2010
This paper examines what is still a relatively new phenomenon in the literature, the outsourcing/offshoring of high-technology manufacturing and services. This has become a concern for both policy makers and academics for two reasons. Firstly, policy makers have become concerned that the offshoring of high-technology sectors in the West will follow the more labour intensive sectors, and move to lower cost locations. Secondly, international business theory has tended to view low costs, and high levels of indigenous technological development as being the two main drivers of location advantage in the attraction of FDI. We show that this may not be the case for offshored high-technology manufac…
Effect of Wind Turbulence on Extreme Load Analysis of an Offshore Wind Turbine
2019
Abstract Evaluation of dynamic responses under extreme environmental conditions is important for the structural design of offshore wind turbines. Previously, a modified environmental contour method has been proposed to estimate extreme responses. In the method, the joint distribution of environmental variables near the cut-out wind speed is used to derive the critical environmental conditions for a specified return period, and the turbulence intensity (TI) of wind is assumed to be a deterministic value. To address more realistic wind conditions, this paper considers the turbulence intensity as a stochastic variable and investigates the impact on the modified environmental contour. Aerodynam…
Product Recalls and Supply Chain Responsiveness
2015
The increase in product recalls which occurred in recent years is mainly due to the globalization of the supply chains, in particular the outsourcing and offshoring of manufacturing and distribution. Besides being the main cause of recall, in this paper we argue that outsourcing (domestic and international) and offshoring may also affect the supply chain responsiveness in managing the recall itself. We test a number of hypotheses on this theme empirically on the pharmaceutical sector by using data collected from the American Food and Drug Administration (FDA).
Aquaculture in Sicily: the state of the art
2009
Aquaculture in Sicily, represented almost exclusively by seabass and sea bream production, together with capture fishery, plays a significant role in the regional economy. On a national basis, the regional production covers about 20% of Italian euryha- line fish production. Fingerling supply is guaranteed by the two hatcheries present on the Island. Twelve floating cage farms and two inshore farms annually produce about 4,000 t of fish. A small extensive production arises from the storage basins of the salt work of Trapani. This niche production could represent an opportunity to realize a new distinctive organic aquaculture, preferred by the consumers respect to intensive produced fish, tha…
Europe's offshore winds assessed with synthetic aperture radar, ASCAT and WRF
2020
Europe's offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of synthetic aperture radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced Scatterometer (ASCAT) ocean wind maps. The wind statistics at 10 and 100 m above mean sea level (a.m.s.l.) height using an extrapolation procedure involving simulated long-term stability over oceans are presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid spacing with data …
Europe’s offshore winds assessed from SAR, ASCAT and WRF
2019
Abstract. Europe’s offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of Synthetic Aperture Radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced SCATterometer (ASCAT) ocean wind maps. The wind statistics at 10m and 100m height using an extrapolation procedure involving simulated long-term stability over oceans is presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid resolution with data every 30 minutes during 30 years f…
Extended Environmental Contour Methods for Long-Term Extreme Response Analysis of Offshore Wind Turbines1
2020
Abstract Environmental contour method is an efficient method for predicting the long-term extreme response of offshore structures. The traditional environmental contour is obtained using the joint distribution of mean wind speed, significant wave height, and spectral peak period. To improve the accuracy of traditional environmental contour method, a modified method was proposed considering the non-monotonic aerodynamic behavior of offshore wind turbines. Still, the modified method assumes constant wind turbulence intensity. In this paper, we extend the existing environmental contour methods by considering the wind turbulence intensity as a stochastic variable. The 50-year extreme responses …
IT-sikkerhetspolicy for Integrerte operasjoner
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Ved å benytte IKT i alle ledd i oljeindustrien, vil man oppnå hurtigere og bedre beslutninger, og med hjelp av sanntidsdata kan man integrere arbeidsprosesser på tvers av fag og mellom organisasjoner. Denne utviklingen blir i oljenæringen kalt Integrerte operasjoner (IO). Ved hjelp av IO kan operasjoner styres uavhengig av avstand og geografisk lokasjon. Det er satt inn store ressurser på dette feltet, og allerede i dag ser man vellykkede implementeringer av Integrerte operasjoner. Med Internett som en del av bærenettverket for data produsert i oljenæringen, vil trafikken i utgangspunktet være svært …
Governance of global value chains after the Covid-19 pandemic: A new wave of regionalization?
2021
The disruption of the trade and investment activities of multinational enterprises as a consequence of the Covid-19 pandemic has reinvigorated the debate on the configuration of global value chains (GVCs) as well as the risks and challenges associated with offshoring. This article depicts how the pandemic might affect GVC configuration by driving a trend toward a more regional footprint in industries in which resilience and reliability are critical. Such a shift would create new opportunities for reshoring, and affect both the types of upgrading trajectories and the governance systems in value chains. The article also draws from the intersection of the global-strategy and value-chain field…
Semiactive vibration control of offshore wind turbine towers with tuned liquid column dampers using H<inf>&#x221E;</inf> output feedb…
2010
This short paper addresses the problem of vibration in wind turbine towers. These structures are subject to winds and waves causing undesirable vibrations that affect the structure integrity and system performance. In order to mitigate the vibrations of the tower, a controllable tuned liquid column damper is placed on its top. We propose the use of H ∞ control techniques to formulate a control law. Furthermore, the controller uses output feedback to avoid the dependence on the knowledge of the states of the system. Simulation results illustrate the design procedure proposed in this paper.
