Component Failures

Leaks of hydrocarbon to the atmosphere can be a major facility safety risk and personnel occupational health and safety (OHS) risk for oil and gas producing and processing facilities. Normally closed valves that pass or leak in-line are also a major contributor to product loss and facility risk. Component failures of these types have two common and challenging features: they are hard to find among the tens of thousands of potential leak sources, and the leakage rates either to the atmosphere or in-line can vary from minor to potentially catastrophic. In the past seven to eight years, advanced methods for finding and managing leaks resulting from poor component integrity have been developed. This paper covers some of ATMECO’s accumulated knowledge developed over many leak surveys of both onshore and offshore oil and gas facilities. Typical statistical profiles of leaks from uncontrolled facilities are presented. The types of component failure that lead to leaks are discussed along with probabilistic analyses relating to the next likely failure. Technologies of leak detection are reviewed, highlighting benefits and problems. Also discussed are the prerequisite data capture and management systems needed for a competent, robust and auditable system to manage component integrity. Gas imaging technology is becoming one of the core hydrocarbon leak detection tools and also assists greatly in the analyses of leaks and in providing valuable input to remedial actions. Survey design requirements for continuing and cost-effective component leak risk management are reviewed. Recommendations are provided about the preferred methods and management structures for programs designed to minimise component integrity risks.

Fixed platform have been widely employed in the offshore oil and gas reservoirs development. Pile foundation reliability is critical for these platforms where drilling, production and other functions are integrated. The lifting operation for the long pile, being a key step in the jacket installation, has been considered for further developments. With deep water developments, the sizes and weights of long piles are reasonably bigger. The corresponding process and equipment employed are subsequently altered, which brings challenges to developing a cost-effective, easy-operable approach for lifting operation. In this paper, the technology for the offshore long pile upending lifting operation including pile feature, installation methodology, lifting rigging and analysis model, covering water depths ranging from shallow to near deep water zone (60–300 m water depth) has been suggested. In addition, the applicability of the adoptable novel approaches has been discussed considering the practical project experience.

Traditionally separators that are used for separation purposes in oil and gas industries are often bulky in size and incur high operating costs. Latest research has led to the development of a novel and compact inline separator, which is even cost effective. This paper exhibits the efficiency of the inline separator determined for two-phase and three-phase separation in multiphase pipelines. Laboratory tests were carried out to remove sand and water using large diameter, industrial-scale test facilities. For the removal of water in oil/water pipeline, separation tests were carried out with liquid velocities ranging from 0.5 ∼ 2 m/s with 10, 50 and 90% water cuts. At first stage, effectiveness in excess of 90% was attained in each of the water cuts. In second stage separation, an effectiveness of 95% was achieved. For the removal of sand in sand/gas pipeline, gas velocities varying from 4 to 14 m/s were investigated. Here, the amount of sand collected after the separation was 99.9% of the total volume inserted into the system before separation. Separation tests for three phases, gas/liquid/sand were also carried out with string of superficial gas velocities of 4 to 10 m/s and superficial liquid velocities of 0.5 to 1.5 m/s. In this case, effectiveness of around 99% was obtained. Thus it can be concluded that the innovative, inline separation system can effectively remove sand and water and reduces or eliminates the risk of corrosion/erosion problems.

Turbine Installation

We can learn from the offshore oil and gas experience for the future offshore wind turbine installation. For the offshore ‘wind farm’ developments, the installation of wind turbines onto preinstalled foundations using the heavy lift vessel method or stabilized vessel is now well established, though, for large units, this requires multiple lifts and hence extensive offshore assembling. As demand for lift vessels increases, their availability to match a future large specific project’s schedule cannot be guaranteed. Consequently, an alternative wind turbine installation vessel design has been developed for not only installing simultaneously two wind turbines in a single piece, but also with a high air gap (up to 70 ft). This paper presents this new design. The new vessel design consists of a catamaran shaped vessel with dimensions that permit it to go around variety of substructures (piles foundation, tripod, concrete foundation or floating substructure) for float-over installation of wind turbines. For the float-over operation, a thorough understanding of dynamic behavior and environmental conditions are necessary to allow the design load to be assessed, with the objective to minimize the risk and maximize the operating sea states. This paper gives a description of how the substructure / Wind turbine / transition piece / floating unit can be modeled. This new vessel design greatly extends the geographical range for offshore wind turbine installation using the float-over method and offers a cost effective alternative to relying on crane vessels.

The offshore oil and gas industry has seen a continual trend of conservatism in design for applications where a high level of strain is expected during the installation phase, leading to a tightening of the acceptable mechanical property performance of the linepipe. This is especially true with regards to longitudinal tensile properties in the strained and aged condition. Due to the expected change in data seen throughout previous projects, are the tightening expectations realistic for the manufacturers and cost effective for the client? The current condition that is widely accepted for the release of pipes suitable for high strain events is straining and ageing. However is this appropriate given that pipes are coated (aged), installed (strained) then left over time (aged)? These questions will be investigated through a series of tests and data analysis. For this project a conventional ageing as per the standard and a coating simulation were used, with all test pieces having either 0% or 1% applied strain. The test pieces for this project were tested in one of seven conditions; • As manufactured • Aged (at 200°C/5min or 250°C/1hr) • Strained and aged (1% strain applied then aged at 200°C/5min or 250°C/1hr) • Aged and strained (aged at 200°C/5min or 250°C/1hr then 1% strain applied) To ensure a direct comparison in the data the comparable test pieces were taken from the same circumferential position on the pipe. All testing for this project was carried out on material of a similar composition and future development of this work will comprise of documenting the effect on different microstructures, t/D ratios and levels of strain. It was clear from the project that changing the conditions used had an impact on the results. This could have implications for the industry in the future and has set up a scheme of development following on from this project to gain a greater understanding.

With the development of the offshore oil and gas fields, multiphase transportation technology is becoming more and more important because it’s a cost-effective way for marginal and offshore fields. However, the complexity characteristics of the gas-oil-water multiphase flow, the hard offshore environmental conditions bring huge challenges to offshore platforms, subsea production systems, subsea pipelines and risers. Severe slugs in offshore risers, hydrate and wax block in subsea pipelines and flowlines will appear when the production system is shut down. In this paper, an experimental facility to simulate the riser slug flow is built, and the flow pattern of severe slug is given, the effects of the incline angles and viscosities on the formation of severe slugs in the riser is experimentally studied and analyzed using water-air, oil-air and water-oil and air. On this base, a cost effective real-time recognition technology of severe slug in the riser is present and its related automatic throttle control method has been validated by natural gas and crude oil with the 25m high riser system, which devotes to the future deepwater riser slug control system.

Offshore oil and gas platforms present a harsh environment for their installed infrastructure, with pipelines that are subjected to both a corrosive atmosphere and transport of aggressive chemicals being the most critical. These conditions have prompted the industry to substitute metallic pipelines for composite counterparts, often made from fiber-reinforced plastics assembled with bonded joints. Various technologies have emerged in recent years to assess the health of these composite pipelines. In particular, robust speckle metrology techniques such as shearography, although not capable of long-term monitoring, have produced very satisfactory results. However, these inspection techniques require specialized equipment and trained personnel to be flown to offshore platforms, which can incur in non-trivial inspection costs. In this paper, we propose and demonstrate a robust and cost-effective approach to monitor pipeline bonded joints during assembly and operation using fiber Bragg grating (FBG) sensors embedded into the joints’ adhesive layer. This approach allows for informed decisions on when to perform targeted in-depth inspections (e.g., with shearography) based on both real-time and long-term feedback of the FBG sensors data, resulting in lower monitoring costs, a severe increase in monitoring uptime (up to full uptime), and increased operational security.
