Independent Inquiry

On 2 September 2006 a reconnaissance aircraft Royal Air Force Nimrod XV230 suffered a catastrophic mid-air fire on a mission over Afghanistan, leading to the total loss of the aircraft and the death of all 14 service personnel. This paper summarises key issues from an independent inquiry and challenges the oil and gas industry to reflect on these. The author, a Chartered specialist in human and organisational factors, contributed to The Nimrod Review as a Specialist Inspector with the UK Health and Safety Executive.

In the United Kingdom, oil and gas workers have been transported by helicopter to their workplace at offshore installations for more than fifty years. During that time, there have been numerous fatal helicopter accidents. Despite calls from trade unions, families, and politicians, a public inquiry has never been held into offshore helicopter transport. The authors consider whether enough has been done to ensure the safety of these workers to meet legal and ethical standards. They analyze the legal position, the implementation of recommendations made in the wake of these accidents, and the way in which the power imbalance between oil and gas companies and helicopter operators influences safety in this area. They conclude that a public inquiry is required into helicopter safety in the U.K. Continental Shelf area.

In the last 12 months or so, particularly with the drop in oil price, there’s been a lot of speculation about the future of the Australian oil and gas industry. Strenuous efforts are being made to bring down costs, reduce complexity and expedite the completion of major capital projects. Yet with the commodity price looking likely to be subdued for some time, serious questions persist. How can we sustain activity in Australia, secure the investment needed to continue exploration and appraisal drilling, for the next wave of projects? In looking for answers to these challenges, collaboration is a theme that comes up time and time again. But what does it actually mean? What does it look like in practice? Who does it well and how? And which companies are reaping the rewards of great collaboration? To fill this knowledge gap we are launching a survey which will look at many aspects of collaboration in the Australia and compare this with the results of similar surveys conducted in the UK. We will be looking to survey both operators and service companies working in the Australia and find out: What does collaboration mean? What constitutes effective collaboration? How do companies view themselves and each other as collaborators? How does collaboration in Australia compare with companies in the North Sea? We hope a better understanding of collaboration could help companies in Australia continue to improve productivity and efficiency, adopt new ways of working, and truly make the most of Australia’s abundant resources.

Piggyback configurations of pipelines, such as a Direct Electrical Heating (DEH) cable mounted on production flowlines, are becoming a common occurrence in the offshore oil and gas industry and they have been observed to excite into a type of flow-induced vibration called galloping in the presence of strong currents at free span locations. This work was aimed at studying potential flow induced galloping vibrations of piggyback type of pipelines commonly used on offshore installations in the oil and gas industry. Tests were carried out in a 12m long, 0.7m wide and 1.2m deep current flume tank located at the NTNU/SINTEF Hydrodynamic Laboratory in Trondheim, Norway. The tank has a test rig with cylinders suspended horizontally on a set of springs mounted on it. Reduced velocities were ranging from 4 to 15, depending on the equivalent diameter of the piggyback pair. In this experimental work, the effects of different diameter ratios and the angle of attack of the flow on the cylinders arranged normal to the flow were investigated. Three different diameter ratio cases were investigated: D+0.5D, D+0.32D and D+0.25D. Attack angles 0°, 30°, 60°, 90°, 120°, 150° and 180° were tested for these 3 diameter ratios giving a total of 21 test cases. The results obtained show that, for all cases of diameters ratios, high response amplitude ratios, as high as 1.7, can occur at reduced velocities less than 10 when the angle of attack is at 90°. It was also observed that vibrations that are characteristic of galloping instabilities occurred at an attack angle of 180° for the D+0.5D and the D+0.32D configurations. For the D+0.25D case, the response amplitudes were similar to a VIV situation. Comparing the response of the different diameter ratios show that the largest pipeline to piggyback ratio gives the largest responses for all attack angles.

Economic Analyses

The Canadian Standards Association (CSA) initiated effort in 1984 aimed at the development of an offshore code for production structures in the oil and gas industry. The present paper summarizes the rationale behind the development of design load specifications in the preliminary standard S.471 "General requirements, design criteria, the environment, and loads." As part of this development, background calibration studies were conducted in tandem with the work of various committees. Selected results from these studies are also discussed in this paper. The basic objectives and tools for developing load criteria for the design of offshore installations are discussed. The use of economic analyses of cost versus safety of structures does not provide clear guidance, and the perspective taken is that of acceptable risks to an individual. This is used in the context of limit states design, which, in S.471, incorporates two safety classes. In order to provide consistent safety levels, the environmental loads are divided into categories based on frequent and rare occurrence, examples being waves and earthquakes, respectively. The role of the annual probability of failure in setting target levels of reliability as well as in the calibration process is emphasized. Various aspects of calibration are summarized, including the background to the rare-frequent separation of loads, the objective function used to optimize the results, as well as the method of handling model uncertainty. Key words: environment, limit states, loads, offshore, reliability, resistance, safety, structures.
