There have been reports of strong submerged jet currents in the Gulf of Mexico in recent years which have implications for the design and operation of some offshore facilities. This paper describes the methodology and results of a screening study which searched for such events within the extensive body of recent data collected by the offshore oil and gas industry, made available on the NOAA National Data Buoy Center web site. This study was conducted on behalf of a consortium of industry clients with participation by relevant US government bodies. After a first phase investigation, initially well defined screening criteria were revised to avoid the numerous events triggered by clearly invalid data and the potential for missing some critical submerged events. The automatic screening criteria were replaced by manual event selection based on plots showing all available data. The identified events fall into the following broad categories: • Submerged speed peaks due to inertial period currents, most notable after the 2005 hurricanes. • A few submerged jet like events isolated in time with no clear periodicity. • Submerged speed peaks with high vertical and error velocities and often incoherent structures. • Persistent high speed currents near the limit of the ADCP range.

Safety Features

Abstract Background Transportation events are the most common cause of offshore fatalities in the oil and gas industry, of which helicopter accidents comprise the majority. Little is known about injury distributions in civilian helicopter crashes, and knowledge of injury distributions could focus research and recommendations for enhanced injury prevention and post-crash survival. This study describes the distribution of injuries among fatalities in Gulf of Mexico oil and gas industry-related helicopter accidents, provides a detailed injury classification to identify potential areas of enhanced safety design, and describes relevant safety features for mitigation of common injuries. Methods Decedents of accidents during 2004–2014 were identified, and autopsy reports were requested from responsible jurisdictions. Documented injuries were coded using the Abbreviated Injury Scale (AIS), and frequency and proportion of injuries by AIS body region and severity were calculated. Injuries were categorized into detailed body regions to target areas for prevention. Results A total of 35 autopsies were coded, with 568 injuries documented. Of these, 23.4% were lower extremity, 22.0% were thorax, 13.6% were upper extremity, and 13.4% were face injuries. Minor injuries were most prevalent in the face, neck, upper and lower extremities, and abdomen. Serious or worse injuries were most prevalent in the thorax (53.6%), spine (50.0%), head (41.7%), and external/other regions (75.0%). The most frequent injuries by detailed body regions were thoracic organ (23.0%), thoracic skeletal (13.3%), abdominal organ (9.6%), and leg injuries (7.4%). Drowning occurred in 13 (37.1%) of victims, and drowning victims had a higher proportion of moderate brain injuries (7.8%) and lower number of documented injuries (3.8) compared with non-drowning victims (2.9 and 9.4%, respectively). Conclusions Knowledge of injury distributions focuses and prioritizes the need for additional safety features not routinely used in helicopters. The most frequent injuries occurred in the thorax and lower extremity regions. Future research requires improved and expanded data, including collection of detailed data to allow characterization of both injury mechanism and distribution. Improved safety systems including airbags and helmets should be implemented and evaluated for their impact on injuries and fatalities.

Significant Events

Corporate mergers in the oil and gas industry in the late 1990s were accompanied by reduced spending for exploration and drilling on the Outer Continental Shelf of the gulf of mexico, even though oil prices were skyrocketing. this lack of response to a favorable price environment is an anomaly for product market theories and can better be understood within a framework of causal history. This approach begins with significant events and traces specific causes and consequences. One significant consequence of the mergers is a redefinition of loyalty among a workforce exposed to increasing employment insecurity.

Nanotransformations of a blanket at the fair dimensional combined processing with imposing of electric field the tool in the form of untied metal granules are considered. An object of researches are the figurine details applied in aviation, the missile and space equipment and in the oil and gas industry: driving wheels and a flowing part of cases of turbo-pump units, screws, krylchatka where there are sites of variable curvature with limited access of the tool in a processing zone.It is shown that the combination in the combined process of two-component technological environments of current carrying granules and the electroconductive liquid environment given with a high speed to a processing zone allows to receive the required quality of a blanket; action of electric field from a source with the increased tension allows to create at fair dimensional processingthe required peening from blows of firm granules. It gives the chance to raise a resource and durability of responsible knots of the aerospace equipment and oil and gas equipment, to expand the field of use of the combined processing with untied granules on a detailwith the sitesnot available to processing by a profile electrode.

Recent years have seen an increase in high-speed electric compression for Oil & Gas applications where high-speed electric motors drive compressors directly without intermediate gears. To date induction machines have been the predominant workhorse of the industry. The permanent-magnet machine technology provides an alternative that promises a highly reliable and robust system design, especially in applications where motor and compressor are fully integrated and share the same process gas environment. This paper provides an update on the recent progress in developing the permanent magnet technology for Oil & Gas applications in which the process gas may contain corrosive elements.

The industrial Trent is the largest aeroderivative gas turbine available, at 50+ MW, and the most efficient gas turbine available to industrial and marine operators, at 42%. Its Dry Low Emissions combustion system embodies the features of the similar combustor on the industrial RB211, which is enjoying very successful service experience. Its design features and derivation from the aero engine are reviewed, together with an assessment of the maintenance aspects of the engine. The current status of the engine validation programme is discussed, covering both component rig testing and progress on the full engine testing being carried out in Montreal, Canada. The applications of the industrial Trent are considered by reviewing the major markets and examining its suitability, both technically and economically, for several existing and emerging sectors. Launched as a power generation machine, the industrial Trent is shown to be well suited to those sectors which have resulted from the growing deregulation of this industry worldwide. In addition it is shown to be attractive for certain applications in the oil and gas industry and, in the marine market, for some large high speed vessel concepts.

After almost two years, the implications of the Montara incident and the more recent Macondo disaster are still evolving. Failure of safety critical barriers led to the Montara blowout and spill. Why did these barriers fail and what are the associated lessons for operators, regulators and governments? There are parallels with the Macondo Incident in the Gulf of Mexico and while many of the insights are particular to drilling, there are others that are applicable to other activities in the oil and gas industry. While the deepest impacts of the Macondo disaster are felt by the families and friends of those who were killed and injured, the broader implications affect the oil and gas industry itself, other industries that expect to co-exist with the petroleum industry, governments and communities, and all those—employees and investors—whose economic future is linked with the industry. Questions we should all be asking include: Is a particular operator competent enough to prevent problems? Can they afford to pay should things go wrong? Are today’s facilities being designed and built to maximise inherent safety ? Do they automatically fail safe when things go wrong ? Have we set up our regulators for success?
