Proceedings of the Annual Offshore Technology Conference | Year: 2013
The offshore industry has been very successful at reducing occupational safety incidents with a dramatic improvement in lost time and recordable incidents statistics. However, major accidents have proven much more resistant to reduction. The methods that have delivered the occupational safety improvements have not worked as well for major accidents. Risk assessment is a powerful approach, but to date it has been more successful at design stage to ensure facilities have suitable layout and separations, provide safe refuges, and protect escape and evacuation against a range of possible hazard events. The author describes in this paper an integrated approach that addresses risks effectively during operations stage with the intent of providing practical risk management tools for offshore drilling, production operations, and support activities. This is built around the now well-known bow tie methodology, but it extends the model in several important directions. Copyright 2013, Offshore Technology Conference. Source

Scenarios for future shipping emissions in the North Sea have been developed in the framework of the Clean North Sea Shipping project. The effects of changing NOx and SO2 emissions were investigated with the CMAQ chemistry transport model for the year 2030 in the North Sea area. It has been found that, compared to today, the contribution of shipping to the NO2 and O3 concentrations will increase due to the expected enhanced traffic by more than 20 and 5%, respectively, by 2030 if no regulation for further emission reductions is implemented in the North Sea area. PM2.5 will decrease slightly because the sulfur contents in ship fuels will be reduced as international regulations foresee. The effects differ largely between regions, seasons and date of the implementation of stricter regulations for NOx emissions from newly built ships. © 2016 Author(s). Source
Advances in Safety, Reliability and Risk Management - Proceedings of the European Safety and Reliability Conference, ESREL 2011 | Year: 2012
Accidents like Buncefield and Texas City have put the risk to people in occupied buildings high on the management agenda. Regulation for design and siting of occupied buildings is evolving and the need for accuracy and transparency has increased. For example, regulatory guidelines like API RP 752 and RP 753 provide guidance on the design and location of permanent and portable buildings to minimise risks to occupants. This paper focuses on advances in software models for assessing risks to people in buildings from releases of flammable materials. When deciding on location and construction of buildings near hazardous installations, a number of factors must be considered. Key to this process is the level of risk to which it is acceptable to expose building occupants. Traditional QRA tends to use "generic" vulnerability for people indoors. The likelihood of death due to exposure to radiation or explosion effects is treated as being independent of the type of building within which they reside. This is obviously a significant limitation to using the QRA results in selecting appropriate building types or to help locate buildings to minimise risk to occupants. Risk to building occupants is a function of both building location and construction. In order to minimise risks to personnel in the most cost effective way, analysts need to be able to compare and assess different options with ease. This paper describes recent advances in the capabilities of the Phast Risk QRA tool (Cavanagh et al. 2009, Cavanagh 2010) which allow analysts to assess the relative benefits of using different building types to reduce risks to their occupants. These new features enable individual definition of building types and associated occupant vulnerability. In addition, GIS facilities allowing analysts to locate buildings of a particular type in various locations help ensure overall risks can be minimised, or location specific risks for particular buildings can be assessed. A case study is used to illustrate the application of the new modelling to selecting suitable building types, and locating them in the most appropriate position to minimise risks to occupants. In addition, techniques are described for using these methods to help locate and design buildings to withstand the possible explosion and flammable effects to which they may be subjected. © 2012 Taylor & Francis Group.

« Local Motors introduces first 3D-printed car series; pre-sales to begin in 2016 | Main | Frost & Sullivan forecasts Gasoline Particulate Filters to climb from 50,335 units now to 4.2-4.6 million units by 2020 » Shell marked the official opening of the Quest carbon capture and storage (CCS) project in Alberta, Canada, and the start of commercial operations there. Quest is designed to capture and safely store more than one million tonnes of CO each year—equal to the emissions from about 250,000 cars. Quest was made possible through strong collaboration between the public and private sectors aimed at advancing CCS globally. Using activated amine (ADIP-X), Quest will capture one-third of the CO emissions from Shell’s Scotford Upgrader, which turns oil sands bitumen into synthetic crude that can be refined into fuel and other products. The CO is a byproduct of the production of hydrogen, which is used to upgrade the bitumen. The CO is then transported through a 65-kilometer pipeline and injected more than two kilometers underground below multiple layers of impermeable rock formations. Te Storage zone is a formation called Basal Cambrian Sands (BCS). It features multiple caprock and salt seal layers. No significant faulting is visible from wells or seismic analysis. The BCS is well below hydrocarbon-bearing formations and potable water zones in the region. Quest is now operating at commercial scale after successful testing earlier this year, during which it captured and stored more than 200,000 tonnes of CO . Quest has a robust measurement, monitoring and verification program agreed upon with the government and verified by a third party (Det Norske Veritas (DNV)). Quest was built on behalf of the Athabasca Oil Sands Project joint-venture owners Shell Canada Energy (60%), Chevron Canada Limited (20%) and Marathon Oil Canada Corporation (20%), and was made possible through strong support from the governments of Alberta and Canada who provided C$865 million in funding. The governments of Alberta and Canada contributed C$745 million and C$120 million respectively to Quest. As part of its funding arrangements, Shell is publicly sharing information on Quest’s design and processes to further global adoption of CCS. Quest draws on techniques used by the energy industry for decades and integrates the components of CCS for the large-scale capture, transport and storage of CO . Collaboration is continuing through Quest between Shell and various parties in an effort to bring down costs of future CCS projects globally. This includes cooperation with the United States Department of Energy, and the British government on research at the Quest site. Support from the local community was essential to building Quest, Shell noted. Shell initiated public consultation in 2008, two years before submitting a regulatory application. Public consultation was developed in collaboration with the Pembina Institute, a Canadian think tank focused on energy issues. A community advisory panel of local leaders and residents will regularly review results from Quest’s monitoring program. Shell and the United States Department of Energy will field-test advanced monitoring technologies alongside the state-of-the-art, comprehensive monitoring program already in place for Quest. Shell is involved in a slate of CCS projects worldwide. The proposed Peterhead CCS project in the United Kingdom, currently in the design stage, is part of the UK Government’s CCS Commercialisation Programme (subject to investor approval and the securing of relevant permits). Shell is also a partner in the Chevron-led Gorgon project in Australia and has a share in the Technology Centre Mongstad (TCM) in Norway. CCS technology developed by Shell subsidiary Cansolv is in use at the commercial-scale Boundary Dam CCS project in Saskatchewan, Canada, which opened in 2014.
« NREL patents method for continuous monitoring of materials during manufacturing; benefits for fuel cell components, semiconductor wafers | Main | U Toronto study measures GDI emissions in urban near-road environment » Hyundai Heavy Industries (HHI), the world’s largest shipbuilder and a leading marine engine maker, has produced the first High Pressure Selective Catalytic Reduction (HP SCR) system for the significant reduction of NO emission from 2-stroke marine engines. The HP SCR can reduce NO emission up to 99% by using ammonia as a catalyst, and thus complies with IMO NOx Tier III requirement that took effect in January 2016. The marine engine add-on can run on heavy fuel oil that costs half as much as marine gas oil. HHI completed the certificate test of the HP SCR, the result of an 18-month long research and development, in December 2015 with the presence of DNV-GL. The first HP SCR is slated to be installed in a 20,600 m3 LPG carrier under construction at Hyundai Mipo Dockyard, a shipbuilding affiliate of HHI, today. HHI has won 5 orders of HP SCR to date, and has set the annual order target of more than 100 units by 2018.
