Impacts of Risk and Service Type on Nearshore and Offshore Investment Location Decisions
Management International Review, 2011Co-Authors: Eugene D. Hahn, Kraiwinee Bunyaratavej, Jonathan P. DohAbstract:Offshoring of services has gained considerable attention in management circles. However, little empirical research has explored the emerging sourcing alternative of nearshoring, despite the fact that firms situate about one out of five projects abroad in a nearshore Location as opposed to an Offshore Location. We empirically assess the impact of economic and risk factors regarding firms’ services Location choices between offshoring and nearshoring. We find these factors influence firm decision-making regarding services offshoring Location choices, and that these factors are more or less important to firms depending on whether the firm Offshores relatively higher versus relatively lower skill services. Offshoring firms appear willing to trade off some gains in one area (lower wages) to mitigate costs in others (higher risk), and that the factors that drive nearshoring are qualitatively different than those that influence offshoring.

Separable but not equal: The Location determinants of discrete services offshoring activities
Journal of International Business Studies, 2009Co-Authors: Jonathan P. Doh, Kraiwinee Bunyaratavej, Eugene D. HahnAbstract:In this paper we explore the question of why firms Offshore particular services to specific geographic Locations. We draw on research related to the unique characteristics of services in trade and commerce, and more recent analyses of the transnational unbundling and spatial dispersion of business processes. We move beyond a simple assessment of the cost sensitivity or relative sophistication of offshoring services and develop a typology emphasizing the degree to which offshoring services activities are interactive, repetitive, or innovative. We suggest that the Location of offshoring projects will depend on the particular mix of these attributes, and test this assertion using a data set of 595 export-oriented Offshore services projects initiated from 2002 to 2005 by US and UK company parents in 45 developed and developing countries. We find that Offshore Location choices greatly depend on these services characteristics, and in sometimes surprising ways, and draw implications from our findings for international business theory, policy, and practice.

surf zone surface retention on a rip channeled beach
Journal of Geophysical Research, 2009Co-Authors: Jamie Macmahan, Jenna Brown, Martijn Henriquez, Timothy P Stanton, Edward B. Thornton, Jeff Brown, Ad J.h.m. Reniers, Edith L. GallagherAbstract:The retention of floating matter within the surf zone on a rip-channeled beach is examined with a combination of detailed field observations obtained during the Rip Current Experiment and a three-dimensional (3-D) wave and flow model. The acoustic Doppler current profiler–observed hourly vertical cross-shore velocity structure variability over a period of 3 days with normally incident swell is well reproduced by the computations, although the strong vertical attenuation of the subsurface rip current velocities at the most Offshore Location outside the surf zone in 4 m water depth is not well predicted. Corresponding mean alongshore velocities are less well predicted with errors on the order of 10 cm/s for the most Offshore sensors. Model calculations of very low frequency motions (VLFs) with O(10) min timescales typically explain over 60% of the observed variability, both inside and outside of the surf zone. The model calculations also match the mean rip-current surface flow field inferred from GPS-equipped drifter trajectories. Seeding the surf zone with a large number of equally spaced virtual drifters, the computed instantaneous surface velocity fields are used to calculate the hourly drifter trajectories. Collecting the hourly drifter exits, good agreement with the observed surf zone retention is obtained provided that both Stokes drift and VLF motions are accounted for in the modeling of the computed drifter trajectories. Without Stokes drift, the estimated number of virtual drifter exits is O(80)%, almost an order of magnitude larger than the O(20)% of observed exits during the drifter deployments. Conversely, when excluding the VLF motions instead, the number of calculated drifter exits is less than 5%, thus significantly underestimating the number of observed exits.

Jack up reliability analysis: An overview
Frontiers of Structural and Civil Engineering, 2018Co-Authors: Ahmad Idris, Indra Sati Hamonangan Harahap, Montasir Osman Ahmed AliAbstract:Jack up is a mobile unit used for oil and gas exploration and production in Offshore fields. On demand, the unit is moved and installed in a given Location and used for a period up to 12 months before being un-installed and moved to another Location. Due to its mobility and re-usability, when the unit is offered for use in a given Offshore Location, its suitability in terms of safe operation is evaluated in accordance with the guidelines of Site Specific Assessment (SSA) of jack up. When the unit failed safety assessment criteria, the guideline recommended that it is re-assessed by increasing the complexity of the assumptions and methods used. Reliability analysis theories are one of the frameworks recommended for the safety assessment of the units.With recent developments in uncertainty and reliability analysis of structures subject to stochastic excitation, this study aims at providing a review on the past developments in jack up reliability analysis and to identify possible future directions. The results from literature reviewed shows that failure probabilities vary significantly with analysis method used. In addition, from the variants of reliability analysis approach, the method of time dependent reliability for dynamic structures subject to stochastic excitation have not been implemented on jack ups. Consequently, suggestions were made on the areas that need further examination for improvement of the efficiency in safety assessment of the units using reliability theories.
