This paper presents some initial results from a twelve-month empirical research study of model driven engineering (MDE). Using largely qualitative questionnaire and interview methods we investigate and document a range of technical, organizational and social factors that apparently influence organizational responses to MDE: specifically, its perception as a successful or unsuccessful organizational intervention. We then outline a range of lessons learned. Whilst, as with all qualitative research, these lessons should be interpreted with care, they should also be seen as providing a greater understanding of MDE practice in industry, as well as shedding light on the varied, and occasionally surprising, social, technical and organizational factors that affect success and failure. We conclude by suggesting how the next phase of the research will attempt to investigate some of these issues from a different angle and in greater depth.

However, design of SCRs for harsh environment is a great challenge, especially from large motion host platforms such as semi-submersible platforms. The key driver for the design of SCR in harsh environment is the fatigue near hang-off and at touch down point.This paper describes the concept of weight optimized SCR design for deep water harsh environment fulfilling both strength and fatigue requirements. The concepts incorporate presently available materials and technology. For the fatigue critical cross-sections, some qualified cost-effective and easily installable solutions are proposed. These proposed concepts are demonstrated through case studies of a few common riser sizes for such deep water field development with large vessel motions.
