An integrated approach for the development of welding, inspection, and alternative weld flaw acceptance criteria, as used for girth welds during pipeline construction is presented. Welding is typically the pace limiting step during pipeline construction and is critical element of pipeline integrity. As such it is vital that it be completed efficiently and with high quality. Each of these three elements is vitally important to welding productivity and quality. At the core of the approach is the coordination of the three elements such that they are developed in concert. By this coordinated effort, all design options are considered leading to optimization of the final outcome. The approach is described by providing an example alternative weld flaw acceptance criteria, and giving the logic pertaining to choices of welding setup, AUT setup, the standard used for design and construction, and the impact of choices within these three elements on the final outcome. The paper illustrates the importance of a unified approach on weld productivity and quality.

The Impact

The fatigue loading on deepwater risers results in the need to impose very tight weld acceptance criteria for pipe alignment and flaw sizes. The production of high-pressure, high-temperature reservoirs calls for increasingly thick-walled riser systems. The combination of thicker wall pipe and the maintenance of tight flaw acceptance criteria challenges automated ultrasonic testing (AUT) which is the primary method of riser weld inspection. An understanding of the limitations of the weld inspection system must be determined and accommodated as part of the engineering process and in conjunction with adequate knowledge of the pipe end dimensions can help optimize the inspection process. This paper discusses the challenges associated with the preparation for and inspection of thick-walled riser system welds and the impact this can have on the system design and engineering requirement. In support of the discussion an overview of a recent study to determine the detect-ability and sizing accuracy of an AUT system with thick-wall pipe girth welds is presented. The qualification program is based upon the AUT inspection of seeded defect welds which are subsequently cut into weld rings, re-inspected with an immersion scan and sectioned to determine the size of the flaws present. All AUT inspections are performed under similar conditions to the inspection of the production welds (i.e., no prior knowledge of the nature of the seeded welds).

Risk Assessment Methodology

This paper examines how changes to pipeline construction specifications/practices can impact both technical and economic considerations of the overall project. The main topics of concern fall under the general headings of joining design, welding, and nondestructive examination (NDE). The different options for the project-specific construction specifications include a discussion of recommended construction practices, and includes an assessment of the risks associated with the different construction alternatives. The following six specific issues were considered significant to the risk of construction-related issues and these were the focus of this scope of work: • Assess the design requirements for joining pipe with different wall thickness, and specifically the use of counterbored and tapered transition pieces; • Examine the impact of specific welding-related construction activities such as release of internal line-up clamps used for welding; • Examine the need for hot pass deposition before removing the internal line-up clamp; • Examine the delay time between weld passes and the total time to complete each weld; • Investigate delay time before completion of weld NDE; • Consider the differences between the use of gamma and x-ray NDE, and the likelihood of detecting weld flaws. A semi-quantitative risk assessment methodology has been developed to calculate the likelihood of failure from planar defects in girth welds. The failure frequencies of girth welds have been based on industry experience, and combined with the likelihood of detection using nondestructive examination techniques, it is possible to show the likelihood of failure during either hydrostatic testing or subsequent service of the pipeline. The results of such an analysis can be used to evaluate the risks associated with changes to construction practices along the pipeline right-of-way.

The fracture mechanics based engineering critical assessment (ECA) method has been accepted as a fitness for service (FFS) approach to defining weld flaw acceptance criteria for pipeline girth welds. Mechanized gas metal arc welding (GMAW) processes are commonly used in cross country pipeline girth weld welding because of the advantages in good quality and high productivity. With the technical advancements of non-destructive testing (NDT) techniques, automated ultrasonic testing (AUT) has greatly improved flaw characterization, sizing and probability of detection during weld inspection. Alternative weld flaw acceptance criteria are permitted in pipeline construction code to assess the acceptability of mechanized girth welds using an ECA. The use of an ECA based weld flaw acceptance criteria can significantly reduce the construction cost. Mechanized girth weld acceptance criteria have been progressively transitioned from workmanship standards into using fitness for service based ECAs. To successfully deliver an ECA on a pipeline project, a multidisciplinary approach must be taken during the welding design and construction stages. Welding, NDT, mechanical testing and field control are all integral elements of pipeline construction. All these four elements have to be fully integrated in order to implement the ECA and achieve the overall integrity of a pipeline. The purpose of this paper is to discuss the importance of the integration of these four elements necessary for proper implementation of the ECA weld flaw acceptance criteria.

The Impact

Honey bees and the pollination services they provide are fundamental for agriculture and biodiversity. Agrochemical products and other classes of contaminants, such as trace elements and polycyclic aromatic hydrocarbons, contribute to the general decline of bees’ populations. For this reason, effects, and particularly sublethal effects of contaminants need to be investigated. We conducted a review of the existing literature regarding the type of effects evaluated in Apis mellifera, collecting information about regions, methodological approaches, the type of contaminants, and honey bees’ life stages. Europe and North America are the regions in which A. mellifera biological responses were mostly studied and the most investigated compounds are insecticides. A. mellifera was studied more in the laboratory than in field conditions. Through the observation of the different responses examined, we found that there were several knowledge gaps that should be addressed, particularly within enzymatic and molecular responses, such as those regarding the immune system and genotoxicity. The importance of developing an integrated approach that combines responses at different levels, from molecular to organism and population, needs to be highlighted in order to evaluate the impact of anthropogenic contamination on this pollinator species.

AbstractThe purpose of this article is to assess how Islamic finance can act as a vehicle to enhance the current intellectual property rights regime in the Gulf Cooperation Council (GCC). Islamic finance has developed within the constraints of sharia law and has been a growth sector for the GCC. This article will identify the main principles of Islamic finance that contribute to the success of Islamic finance, which can enhance intellectual property protection in the GCC. The main sharia-compliant areas to be considered are musharaka, mudaraba, murabaha, takaful, istisna, ijara, salam and sukuk. The article will outline the founding principles of Islamic finance, the governance of sharia boards, development of Islamic finance in the individual GCC states, different frameworks of sharia-compliant investment products and the impact of intellectual property rights on the varying Islamic finance investment tools. Furthermore, the article will discuss an integrated approach to intellectual property rights which learns lessons from the Islamic finance sector in relation to infrastructure, regulation and sharia compliance. The lessons learnt from Islamic finance will inform the overall framework of recommendations for an Islamic intellectual property model. The use of Islamic finance as a vehicle to promote better intellectual property rights in terms of defining a new intellectual property approach is novel. It is aimed at spearheading further research in this area, and it will form a part of the overall integrated approach proposals to intellectual property protection in the GCC and beyond.
