Traditional pipeline technology will be severely challenged as design-operating pressures continue to rise and gas field developments occur in more remote locations including the arctic. Cost-effective solutions to these issues can be found through innovative designs using new technology and its implementation. Some of these designs have considered the use of high-pressure natural gas pipelines resulting in the development of high strength steel. In order to meet these increases in pressure TransCanada and JFE/NKK have been working extensively on the application of X100 (Grade 690) linepipe and this has culminated in the construction and installation of a X100 project in the fall of 2002. This paper will discuss the development of the related research projects that allowed the successful completion of the field project. The topics will include the material properties and fracture control plans for X100. In addition the approach to strain based design for X100 will include the analysis for both the tensile strain limits (weld mismatch consideration) and compressive strain limits (i.e. buckling capacity). The development of the field welding process will also be covered. The paper will discuss the implications of using X100 from the perspective of the successful field project and the application of a strain-based design.

“Sevmash” is one of the biggest Russian shipbuilding enterprises. Its capacity enables high-tech and knowledge-intensive projects to be fulfilled, such as manufacturing of spent nuclear fuel containers, building of modern nuclear-powered submarines (NPS) and marine engineering structures. The enterprise has mastered manufacturing of offshore platforms for oil and gas field development in the Arctic. Now “Sevmash” continues construction of nuclear strategic and multi-purpose submarines of the fourth generation “Borey” and “Yasen”. The article deals with the formation and development of non-destructive testing services from its beginning to the present day. Since 1950s, the radiography of hull structures welded seams and pipelines joints was the main testing method. In 1970s construction of new generation nuclear submarines began; it was necessary to create gamma flaw detectors of new design and they were created within 15 years. Besides in 1970s the active period began for development of ultrasonic testing instruments. In 1970s–1990s, concurrently with radiographic and ultrasonic techniques, testing of welds during the welding process with an acoustic emission method was carried out. In 1990s magnetic particle inspection of welded joints, radiation monitoring, leakage testing with the use of helium leak detectors and vacuum chambers had been extensively developed. The bubble vacuum method of welded connections testing was widely used in the process of repair and re-equipment of surface crafts. Today “Sevmash” actively re-equips its production facilities. It gives “Sevmash” the opportunity to built ships that meet the highest demands.

In the pipe manufacturing and pipe processing industry, the demand for cost-effective pipes with high strength and good ductility is increasing. In the present study, the inductive longitudinal welding process was combined with a Quenching and Partitioning (Q&P) treatment to manufacture pipes with enhanced mechanical properties. The aim of the Q&P process is to establish a martensitic structure with increased retained austenite content. This allows for the beneficial use of both phases: the strength of martensite as well as the ductility of retained austenite. A 42SiCr steel, developed for Q&P processes, was joined at the longitudinal seam by a high-frequency induction (HFI) welding process and was subsequently heat-treated. The applied heat treatments included normalizing, austenitizing, quenching, and two Q&P strategies (Q&P-A/Q&P-B) with distinct quenching (Tq = 200/150 °C) and partitioning temperatures (Tp = 300/250 °C). Investigations of the microstructures revealed that Q&P tubes exhibit increased amounts of retained austenite in the martensitic matrix. Differences between the weld junction and the base material occurred, especially regarding the morphology of the martensite; the martensite found in the weld junction is finer and corresponds more to the lath-type morphology, compared to the base material in the circumference. In all zones of the welded tube circumference, retained austenite has been found in similar distributions. The mechanical testing of the individual tubes demonstrated that the Q&P treatments offer increased strength compared to all other states and significantly improved ductility compared to the quenched condition. Therefore, the approach of Q&P treatment of HFI-welded tubes represents a route for the mass production of high-strength tubular products with improved ductility.

Abstract Obtaining high resolution, quality formation evaluation data is still only possible with wireline logging. However, with the continued push into deeper and more complex drilling environments, many challenges have been placed in the way of wireline logging, including high tension, high deviation, and increased differential pressure. These factors contribute to an increased risk of tool sticking incidents and lost-in-hole scenarios. Several methods of mitigating these issues on surface (powered capstans, pipe conveyance, etc) have been implemented in the past, but none have been successful in reducing or eliminating the risk downhole without introducing further drawbacks. This paper describes how a new wireline conveyance system has eliminated these issues. The conveyance system consists of wheeled carriages that carry the toolstring off-centre. The mass of the toolstring acts as a counterweight to ensure correct tool orientation in the wellbore. This orientation feature also enables a "guide" device to help navigate ledges and washouts. Such a system eliminates toolstring hold ups, allows access to highly deviated wells without pipe conveyance or tractors, and significantly mitigates differential sticking hazards, while also offering additional benefits in operational efficiency and data quality. A case study from a particularly difficult well in New Zealand is presented. Data acquisition in this well was fraught with challenges: In addition to the 2000m tangent section at 67° deviation, well had severe borehole breakouts. Previous experience in similar scenarios with conventional data acquisition methods yeided poor results. The wheeled carriage system was deployed in multiple innovative configurations resulting in the acquisition of excellent quality data from five wireline descents in hole. This wireline conveyance system has been routinely deployed on multiple deepwater operations in the Gulf of Mexico. One such operation is presented where large gains in logging efficiency have been realised, particularly with the elimination of differential sticking risk and time-consuming pipe conveyed logging. The new technology takes a holistic approach to wireline tool conveyance: Prevent sticking issues using wheeled carriages and mitigate fishing risk using ultra-high strength wireline cables. Wheeled carriages greatly reduce the tool-borehole contact area, preventing the incidence of tool sticking. In addition, wheeled carriages reduce drag while ensuring optimum data quality by sensor position and orientation within the wellbore. Ultra-high strength cables provide ability to log at very high tensions and at the same time provide high overpull capability. The result is a safe, efficient, cost effective and complete Wireline data acquisition.

Advanced high-strength steel (AHSS) steels are relatively not very well weldable because of the dominant martensitic structure with coarse ferrite and bainite. The utmost difficulty in welding these steels is their tendency to crack both in the heat affected zone (HAZ) and in weld. The significant disadvantage is that the strength of the welded joint is much lower in comparison to base material. Adopting the new technology regarding micro-jet cooling (MJC) after welding with micro-jet cooling could be the way to steer the microstructure of weld metal deposit. Welding with micro-jet cooling might be treated as a very promising welding S700MC steel process. Tensile and fatigue tests were mainly carried out as the main destructive experiments for examining the weld. Also bending probes, metallographic structure analysis, and some non-destructive measurements were performed. The welds were created using innovative technology by MAG welding with micro-jet cooling. The paper aims to verify the fatigue and tensile properties of the thin-walled S700MC steel structure after welding with various parameters of micro-cooling. For the first time, micro-jet cooling was used to weld S700MC steel in order to check the proper mechanical properties of the joint. The main results are processed in the form of the Wöhler’s S–N curves (alternating stress versus number cycles to failure).

There are a multitude of reasons that a teletinnitus program can be beneficial, not only to the patients, but also within the hospital and audiology department. The ability to use technology for the purpose of tinnitus management allows for improved appointment access for all patients, especially those who live at a distance, has been shown to be more cost effective when the patients travel is otherwise monetarily compensated, and allows for multiple patient's to be seen in the same time slots, allowing for greater access to the clinic for the patients wishing to be seen in-house. There is also the patient's excitement in being part of a new technology-based program. The Gulf Coast Veterans Health Care System (GCVHCS) saw the potential benefits of incorporating a teletinnitus program and began implementation in 2013. There were a few hurdles to work through during the beginning organizational process and the initial execution of the program. Since the establishment of the Teletinnitus program, the GCVHCS has seen an enhancement in patient care, reduction in travel compensation, improvement in clinic utilization, clinic availability, the genuine excitement of the use of a new healthcare media amongst staff and patients, and overall patient satisfaction.

In the present study, galvanized High Strength Interstitial Free (HIF) steel sheets, and Dual Phase (DP780) steel sheets were used for the investigations. Resistance spot weld joints were fabricated between dissimilar steel sheets. The variation in dynamic resistance (DR) with the change in welding process parameters such as weld current, weld time and electrode force were used for establishing the range of adequate weld nugget formation parameters. Effect of these parameters over tensile strength, nugget diameter and the observed failure mode was studied using one factor at a time (OFAT) approach. Microstructure and hardness of parent metal, fusion & HAZ region has also been studied.
