Offshore pipeline is mainly to transport crude oil and gas from offshore to onshore. It is also used to transport crude oil and gas from well to offshore platform and from platform to another platform. The crude oil and gas horizontally flows on the seabed, and then vertically flows inside the riser to the offshore platform. One of current issues of the oil and gas transportation system is an end expansion caused by the axial force. If the end expansion occurs over it limit can cause overstress to riser. This paper explores the effect of axial force toward local buckling in end expansion. In the study, development of programming in visual basic 2010 firstly was constructed using empirical equation. The programming code, then, was validated by comparing simulation result with actual data from company. As case study, the end expansion for various thicknesses of pipes was simulated. In this programming, DNV regulation is included for checking either design complied or not with regulation. However, DNV regulation doesn’t have specific rule regarding the end expansion but it is evaluated under load displacement control under strain condition.

There is a need in engineering education toimprove the connection between design and engineeringscience. Students should be provided more opportunitiesto practice applying both science and design to a singleproblem in order to be better prepared for challengesthey will face when they enter the workforce. For thisreason, an instructor of a first year engineering sciencecourse was motivated to improve its connection to theCanadian Engineering Accreditation Board (CEAB)Attributes, specifically the Design attribute. The goal wasto revise the course such that the students would berequired to integrate quantitative methods that weretaught during the term through the means of design. Itwas decided that an effective pedagogical tool that couldaccomplish this was a case study, since it would providecomplexity and context using a real-world issue thatrelated to several course concepts. The methodology forcase development, implementation strategy, future steps,lessons learned, as well as the instructor’s observationswill be discussed.

Purpose A body of literature and case studies has developed as part of the reporting, outreach and evaluation of the local and regional food system projects supported by grants and other funders. Yet, there is concern that food value chains are promoted without adequately evaluating the viability of these businesses, or how these markets affect the performance and welfare of key stakeholders: farm vendors and local communities/economies. Design/methodology/approach This paper reviews and summarizes a comprehensive set of U.S.-based case studies focused on food value chains. We conduct a meta-analysis to systematically capture what available case study evidence tells us about: 1) trends in the viability of food value chain businesses; 2) the impact of these businesses on participating farm vendors; and, 3) the associated community economic development outcomes (framed in terms of ‘wealth creation’). Findings In addition to sharing findings from the meta-analysis, we demonstrate how the lack of standardized protocols for case study development is a barrier to learning about metric comparisons, best practices, and what impacts these food value chain businesses may have. We conclude with some recommendations of how the field can move forward to evaluate and share lessons learned using more uniform, project-driven case study development. Originality/value This is the first study to conduct a systematic meta-analysis of U.S. food value chain businesses.
