Offshore information systems (IS) project team structures are often treated as given in extant IS research and there is little insight about what criteria should be used to structure these teams. In this study we sought to understand how IS project risks shape the structure of project teams in offshoring. Drawing on the IS project risk literature, we predicted that social and technical subsyste...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

This paper presents the modeling and simulation of offshore wind power platform for oil and gas companies. Wind energy has become the fastest growing renewable energy in the world and major gains in terms of energy generation are achievable when turbines are moved offshore. The objective of this project is to propose new design of an offshore wind power platform. Offshore wind turbine (OWT) is ...

The vibration control problem of offshore jacket platforms is studied. According to Morison equation, the total wave force acting on the offshore structure is obtained and is generated by an exosystem. Considering the nonlinear interaction of pile-soil, which is described by a fifth order anti-symmetric polynomial, the nonlinear dynamical model of offshore platforms affected by the wave load di...

Offshore structures such as jacket platforms have to inevitably be designed against  sever  environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded  in recent earthquakes, including the 1995 Kobe, Japan, 1999 Chi-chi, Taiwan and 1999 Kocaeli, Turkey earthquakes, revealed that the dynamic motions in nea...

Large welded structures, including ships and offshore structures, are normally in operation under cyclic fatigue loadings. These structures include many geometric as well as material discontinuities due to weld joints, and the fatigue strength at these hot spots is of critical importance for the structural performance. In the past, various Non-Destructive Evaluation (NDE) techniques have been d...

We discuss the robust design optimization (RDO) of the support structures of offshore wind turbines to decrease costs and variations considering uncertainties. First, an approximate model derived with design of experiment (DOE) methodology is introduced to replace the time-consuming computational dynamic response analysis of finite element (FE) models for reducing computational costs. Then, a d...
