Traditional pipeline technology will be severely challenged as developments continue in arctic regions. Cost-effective solutions to these challenges can be found through innovative technology and its implementation. TransCanada PipeLines has been involved in a series of technology programs that have been implemented in challenging climates including permafrost. In addition TransCanada is also involved in ongoing programs whose aim is to reduce the cost of Northern pipelines whilst at the same time provide structural assurance and reliability. This paper will describe the overall approach to developing cost-effective solutions and how these programs are interconnected. The topics to be covered will include the approach to strain-based design and how TransCanada has been taking advantage of the approach in its implementation of higher strength steels. The work also includes the approach taken in terms of the design for the effect of mismatch between the pipe and weld metal properties. The strain-based approach is also being extended to a structural reliability methodology and the work conducted to date will be briefly discussed. A significant portion of the design of a Northern pipeline relies on the development of a frost heave-thaw settlement methodology and the current philosophy and its validation will be discussed. A prime consideration of the regulatory bodies is the assurance of structural integrity and fracture control plans. The work currently ongoing at TransCanada on fracture safe behaviour will be discussed. Additional discussion on construction related topics will be covered including welding, buoyancy control, directional drilling and trenching.

Casing Drilling

The evolution of casing while drilling (CwD) illustrates the economic, efficiency and health, safety and environment benefits achievable with the seamless integration of downhole tools and surface drilling equipment. However, several technology gaps have restricted CwD from reaching its full potential to optimise the well construction process. This paper describes the integrated development and application of a retrievable Enhanced Casing Installation (ECI) system, engineered to take directional (Level 3) casing drilling technology to another level and further expand the functionality of both specialised and standard land drilling rigs. The system, which enables directional drilling with composite casing and standard mud motors, differs from typical Level 3 CwD methodologies in that the composite option allows bottom hole assembly (BHA) placement inside the shoetrack, thus helping reduce vibrations and wear on the reamer and other downhole tools. Along with increased well stability and allowing simultaneous logging/measuring while drilling, the ECI device is configured with a comparably lightweight BHA, requiring fewer components, such as jars and roller reamers, making it easily retrievable with cable. As discussed, the cost-effective integration of downhole and surface equipment is clearly reflected in the capacity to rerun the retrieved bit and reamer – a marked difference between the sacrificial bits required for the commonly used Level 2 (vertical) CwD technique. Moreover, the authors will present results of a specialised test stand evaluation and subsequent field trial, where the system was integrated on a fit-for-purpose rig and used for casing drilling at a 45° angle with the BHA pulled intact from 1800 m MD.

The Relationship

Assessments of structural reliability under storm overload have been performed on various monopod configurations located on Australia’s North West Shelf (NWS). The results have shown that these monopods have lower reliabilities than typical platforms in other petroleum provinces, due to a number of factors. In itself, this may not be a concern, as it may be argued that minimum facilities platforms have relatively low consequences of failure. Reasons for this could center around these monopods being satellites with small production throughput, having short service lives, being not-normally-manned, and having environmental protection features which minimize the possibility of a hydrocarbon spill resulting from a structural failure. A suitable target probability of failure for monopod platforms may be computed using a cost-benefit approach, where the total platform cost, including the cost of failure, is minimized. This analysis is developed for four distinct monopod configurations involving single pile, pile cluster and outrigger foundations in water depths ranging between 9-52m LAT. The relationship between platform CAPEX and probability of failure is derived from first principles for cases of appurtenances located within and external to the main caisson.

The Cost

With their simplicity and light structural weight, minimum platforms are a popular solution — even though they may not have the same robustness levels as conventional jackets to withstand extreme or accidental events. These competing attributes are investigated by comparing the cost and structural reliability characteristics of five structures designed using API RP2A. The braced monopod and tripod structures have considerably lower ultimate strengths and residual strengths, and damage scenarios play a much greater role in the overall probability of failure, than for the four-legged jacket. In determining the relative economic merits of the different configurations, the magnitude of the potential consequences of failure becomes an important parameter. Bands of conditional costs of failure for which each structure is the most cost-effective option are derived, with the sturdy monopods and tripod shown to be the optimal solutions for moderate consequence levels.

Gas Fields

The developments of gas fields are increasingly occurring in more remote locations and further from the prime gas demands. Pipeline activity continues to focus on arctic regions of both Canada and the United States. Cost effective solutions to these challenges can be found through innovative technology and the use of higher pressure and higher strength pipelines. TransCanada and its partners have been involved in a series of technology programs on high strength steels, particularly X100, that are focussed on its application for high pressure long distance pipelines. In order to evaluate this technology two field installations of X100 have been performed on the TransCanada system within Alberta. These installations have evaluated the summer and winter construction aspects of X100 pipelines. This paper will describe the work performed to enable the two projects to occur, and the results of the installation. The summer project occurred on the Westpath loop, and consisted of 1 km of NPS 48 by 14.3 mm X100 and was installed in September 2002. The winter project was on the Godin Lake Loop and consisted of 2 km of NPS 36 by 13.2 mm X100 and will be installed in February 2004. The paper will describe the approach taken to the pipe development and the properties required, the requirements for a strain-based design, the fracture control plan, and the welding requirements. Discussion will cover the installations and construction and the conclusions in terms of future projects. The role of code and regulatory bodies in the successful implementation will be covered.

Vegetated swales, or bioswales, are among the most commonly used type of green infrastructure (GI) for managing stormwater in temperate climate regions. However, performance data on bioswale drainage technology applied to highly weathered soils (low fertility, high acidity, and erosion prone) in tropical and subtropical climates are still limited. Aimed at closing this gap, this research investigated the performance—assessed in terms of vegetation biomass, biodiversity and coverage of swale, the structural integrity of revetments, and erosion control potential—and cost effectiveness of five rolled erosion control products (RECPs) currently available on the market, in combination with herbaceous vegetation as the revetment of drainage swales, in tropical soils. Additionally, the research project evaluated the performance of a new preseeded RECP, the Preseeded Reinforcement Mat, for drainage in areas that are difficult to access. The performances of all six RECPs were generally adequate as bioswale revetments in the conditions investigated, with performance index values ranging from 6 to 10 in a 0 to 10 scale. At the same time, some RECPs were more conducive to the growth of regional herbaceous vegetation species, measured in terms of biodiversity, which ranged from 2 to 14 species in the different bioswales, and some were more cost effective than others, with costs ranging from 19% to 106% of the cost of concrete lined swales.

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

Summary Objective: The goal of the study was to assess the effectiveness and patient tolerability of single-session, sonographically guided, transcatheter foam sclerotherapy and to evaluate its economic impact. Patients, methods: We treated 20 patients with a total of 22 varicoses of the great saphenous vein (GSV) in Hach stage III-IV, clinical stage C2-C5 and a mean GSV diameter of 9 mm (range: 7 to 13 mm). We used 10 ml 3% Aethoxysklerol®. Additional varicoses of the auxiliary veins of the GSV were sclerosed immediately afterwards. Results: The occlusion rate in the treated GSVs was 100% one week after therapy as demonstrated with duplex sonography. The cost of the procedure was 207.91 E including follow-up visit, with an average loss of working time of 0.6 days. After one year one patient showed clinical signs of recurrent varicosis in the GSV; duplex sonography showed reflux in the region of the saphenofemoral junction in a total of seven patients (32% of the treated GSVs). Conclusion: Transcatheter foam sclerotherapy of the GSV is a cost-effective, safe method of treating varicoses of GSV and broadens the spectrum of therapeutic options. Relapses can be re-treated inexpensively with sclerotherapy.

This research proposed a model to assist the design of the associated data architecture and data analytic to support talent forecast in the current accelerating changes in economy, industry and business change due to the accelerating pace of technological change. The emerging and re-emerging economy model were available, such as Industrial revolution 4.0, platform economy, sharing economy and token economy. Those were driven by new business model and technology innovation. An increase capability of technology to automate more jobs will cause a shift in talent pool and workforce. New business model emerge as the availabilityand the cost effective emerging technology, and as a result of emerging or re-emerging economic models. Both, new business model and technology innovation, create new jobs and works that have not been existed decades ago. The future workers will be faced by jobs that may not exist today. A dynamics model of inter-correlation of economy, industry, business model and talent forecast were proposed. A collection of literature review were conducted to initially validate the model.

The choice of cost-effective method of anticorrosive protection of steel structures is an urgent and time consuming task, considering the significant number of protection ways, differing from each other in the complex of technological, physical, chemical and economic characteristics. To reduce the complexity of solving this problem, the author proposes a computational tool that can be considered as a subsystem of computer-aided design and used at the stage of variant and detailed design of steel structures. As a criterion of the effectiveness of the anti-corrosion protection method, the cost of the protective coating during the service life is accepted. The analysis of existing methods of steel protection against corrosion is performed, the possibility of their use for the protection of the most common steel structures is established, as well as the estimated period of effective operation of the coating. The developed computational tool makes it possible to choose the best method of protection of steel structures against corrosion, taking into account the operating conditions of the protected structure and the possibility of using a protective coating.

The development and evaluation of brake pads using groundnut shell (GS) particles as substitute material for asbestos were carried out in this study. This was with a view to harnessing the properties of GS, which is largely deposited as waste, and in replacing asbestos which is carcinogenic in nature despite its good tribological and mechanical properties. Two sets of composite material were developed using varying particle sizes of GS as filler material, with phenolic resin as binder with percentage compositions of 45% and 50% respectively. Results obtained indicate that the compressive strength and density increase as the sieve size of the filler material decreases, while water and oil absorption rates increase with an increase in sieve size of GS particle. This study also indicates that the cost of producing brake pad can be reduced by 19.14 percent if GS is use as filler material in producing brake pad. The results when compared with those of asbestos and industrial waste showed that GS particle can be used as an effective replacement for asbestos in producing automobile brake pad. Unlike asbestos, GS-based brake pads are environmental friendly, biodegradable and cost effective.
