The Impact

During severe hurricanes, such as Katrina, the mooring system of a number of Mobile Offshore Drilling Units (MODUs) in the Gulf of Mexico failed. Drifting MODUs may potentially damage other critical elements of the offshore oil and gas infrastructure by colliding with floating or fixed production systems and transportation hubs, or by rupturing pipelines owing to their dragging anchors over the seabed. To avoid or mitigate the damage caused by a drifted MODU, it is desirable to understand the mechanics of the drift of a MODU under the impact of severe wind, wave and current and have the capability of predicting the trajectory of the drift. To explore the feasibility and accuracy of predicting the trajectory of a drifting MODU based on real-time or hindcast met-ocean conditions and limited knowledge of the condition of the drifting MODU, this study employed a simplified equation describing only the horizontal (surge, sway and yaw) motions of a MODU under the impact of steady wind, current and wave forces. The simplified hydrodynamic model neglects the first- and second-order oscillatory wave forces, unsteady wind forces (owing to wind gustiness), wave drift damping, and the effects of the body oscillation on the steady wind and current forces. It was assumed that the net effects of the oscillatory forces on the steady motion are insignificant. To verify the accuracy and feasibility of our simplified approach, the predicted drifts of two MODUs were compared with the corresponding measured trajectories recorded by the Global Positioning System (GPS).

Purpose The purpose of this study is to compare different models integrating the TOC and Lean approaches. Design/methodology/approach The models of reference were identified through a comprehensive literature review. A qualitative and comparative analysis was carried out by pointing out the strengths, weaknesses and gaps of models integrating the TOC and Lean based on the production system requirements. Findings The findings indicate that these models can be improved by introducing aspects related to the system structure such as main key performance indicators, type of shop layout and performance metrics to evaluate the improvements implemented in the production system. The results provided evidence that the TOC and Lean are complementary approaches, and the individual gaps of each approach seem to be, in the most part, offset by the virtues of the other. Practical implications This study enables decision makers and industrial managers to evaluate the practices adopted in the production environment, as well as the use of the different set of continuous improvement practices. This article also minimizes the literature gap regarding whether and how integrated Lean and TOC approach can be used in the firms. Originality/value This study contributes to the body of literature on Lean by comparing three different models integrating Lean and the TOC. Furthermore, a research agenda is suggested for future research aimed at developing new models integrating both approaches, aiming to increase the competitiveness of the production systems.

The Impact

Dry-tree solutions with top-tensioned risers (TTRs) have been successfully used with floating production systems (FPS), such as Spars and TLPs, in a wide range of deepwater applications. Both single-casing and dual-casing top-tensioned risers are field-proven in existing field developments. The top-tensioned risers bring technical advantages and operational cost benefits. However, recent oil and gas developments that have high pressure and high temperature (HPHT) in combination with severe environmental loads push the design limits of conventional steel pipes in deepwater risers. High-strength steel pipes are therefore considered for risers for both technical and economic reasons. This paper discusses the impact of the above requirements on design of top-tensioned risers, and proposes feasible design concepts for top tensioned risers with extremely high pressure requirements. Part I of the topic here addresses strategies of top-tensioned riser sizing and weight management, and design considerations for TTR specialty joints. Part II of this topic will follow for top-tensioned riser tensioning system configuration and tension performance optimization, as well as coupled motion compensation on the host platform. The objective of the study that forms the basis for this paper is to provide top-tensioned riser system configurations that meet the challenges of the extremely high operational pressure and environmental loads in deep and ultra-deep waters.

Oil And Gas Sector

Traditional design and supply chain processes have created well established approaches to the manufacture of metallic engineering products in the Oil and Gas sector. Normative references such as API 6A (Specification for Wellhead and Christmas Tree Equipment) and API 17D (Design and Operation of Subsea Production Systems - Subsea Wellhead and Tree Equipment), as well as national and company-based specifications and requirements (e.g., Brazilian norm NBR 15827 “Industrial Valves for Installations of Exploration, Production, Refining and Transport of Petrol Products - Requirements for Design and Prototype Test” and Chevron specification SSM - PU - 54.02 - A “Qualification Testing of Subsea Equipment”) and the ASME body of pressure vessel code requirements and derived specifications, are largely predicated on traditional design and supply assumptions with respect to metallic materials and components. The further challenge of recovering oil from deepwater basins has generated initiatives such as “Project 20K”, BP’s project to develop, with programme collaborators, the capability to drill, complete, produce and intervene in deepwater reservoirs with pressures of 20,000 psi at the mudline and temperatures up to 350°F (175°C). Here again, design and supply assumptions to date are predicated on traditional design and supply assumptions for metallic materials and components. Notwithstanding the progress being achieved in meeting performance requirements in these and similar programmes, a global paradigm change is underway in respect of the accelerating front of advanced manufacturing. This has been seen especially in the aerospace and aviation sectors, but significantly less so in the Oil and Gas sector. This paper will contribute to addressing this imbalance by presenting work being done by a major subsea equipment supplier to engage with the challenges of this disruptive manufacturing technology. Specifically, the paper will present the holistic approach and results of innovative work being done in the advanced manufacturing of a subsea metallic component using welding arc additive techniques. The work presented will review and evaluate the impact of this manufacturing technology on the core metallic component domains of Metallurgy, Welding Engineering and NDE, utilizing a robotic system for manufacturing the component. The paper directly contributes, therefore, to the emerging roadmap for advanced manufacturing of metallic components in the Oil and Gas sector.

The Impact

Abstract Changes in cow-calf operations and management need to be deliberate and focus on consumer preferences that are substantive and enduring. For the sake of argument these preference changes could include: 1) continued erosion of the image of the cattle industry; 2) growth in demand of high quality grade beef, likely branded, and available at an affordable price; 3) production systems that yield improvements in cattle health, have a lesser environmental impact, and demonstrate prudent animal care and well-being; 4) Specification systems that may or may not include stipulations such as grass fed or non-implanted. At the ranch level there will be continued pressure to pursue rapid, efficient growth, marbling, structural soundness, and immunocompetence via genetic selection. A major step to reduce health problems is to reduce co-mingling. To achieve this goal breeding programs will change to improve the genetic and phenotypic uniformity and possibly the heterosis of the calf crop on each ranch. The National calving season needs to be more uniformly distributed throughout the year. New, more relevant cattle performance metrics will be developed. Calves that fit a branded production stream will have more value. Production streams that require Verified processes will be inequitably distributed across herd size because of associated costs, forcing smaller herds to either coop, vertically integrate, or accept generic cattle prices. Because of the diversity of environments and corresponding compatible bio-types of cows, identifying the profitable combination of specific branded systems with the genetics, calving season, labor, resource management and nutrition program of the ranch is very complicated. It will be increasingly necessary to put incremental response assessments in the context of the greater production-product system. Successful adaptors will place a much greater reliance on strong technical support in the areas of genetics, nutrition, growth, animal handling, documentation, and branded production streams.

Purpose: The SMEs play critical role in creating job opportunities and growth of the economy.  Currently, the rate at which the new firms formed have stagnated and those with less than 5 years are closing down is very high. This has triggered research on the financial performance of the SMEs especially in areas with high levels of poverty since most studies concentrate on developed economies and urban centres. This study investigated the effect of access to finance on financial performance of processing SMEs in Kitui County. Methodology: Descriptive research design was applied to conduct the study. The target population was the 25 processing SMEs in Kitui County where for each firm; the Chief Executive Officer, the finance manager and the Chief accountant were considered as respondents giving rise to a total of 75 respondents. An interview and Semi- structured questionnaires were used to collect primary data from the respondents. The data was inspected for completeness, accuracy, reliability and consistency then analysed using SPSS Version 20 Software. Descriptive statistics such as mean, and the standard deviation were computed to describe the data collected. Moreover, inferential statistics at 95% confidence level were used. Results: The findings of the study indicated that financial performance positively correlated with the access to finance. The findings were supported by the literature reviewed by the study. With reference to the findings, various recommendations were made. Unique Contribution to Theory, Practice and Policy: To start with, the study recommended financial institutions to create favourable policies to enable SMEs access loans easily. Secondly, the study recommended government to offer incentives and funding to SMEs at a lower cost to boost their financial performance. Finally, the study recommended more studies to identify other factors that influenced the financial performance of SMEs in Kenya.

Purpose: The purpose of this study was to establish the effect of integrated ticketing on sustainable mobility in the Matatu Saccos in Nairobi County, Kenya. Materials and Methods: The study was guided by Positivism philosophy while descriptive research design was adopted. The target population was 177 Sacco Managers and two representatives, one from MOT and other from MVOA respectively.  The whole population of 179 respondents was used in the study hence; the study employed the census approach. The questionnaire was pilot tested on 18 respondents who were selected randomly. The study applied Cronbach's alpha and the results displayed a high level of internal consistency hence infers that the research tool used in the study was reliable. The data collection instrument was a semi-structured questionnaire, which were dropped and picked later. A semi-structured interview guide was also used. Data was analysed using descriptive and SPSS Version 24. Results: Correlation analysis indicates that there is a strong positive and significant relationship between integrated ticketing and sustainable mobility of Matatu Sacco in Nairobi County.  (rho = 0.809, p value <0.05). Regression analysis also showed that in general, integrated ticketing is significant in explaining the variation in sustainable mobility of Matatu Sacco’s in Nairobi County, Kenya (β = 1.046, t = 15.872, p<0.05).   Unique contribution to theory, practice and policy: The study recommended that, the Ministry of Transport and the management of the Saccos should formulate substantial policies on how to handle ticketing where the government imposes control of fares. This ensures that there is functional guidance on charging the passengers, which would, in turn, improve customer satisfaction and improve company image.
