The UK particulate matter air pollution episode of March-April 2014: more than Saharan dust

A period of elevated surface concentrations of airborne particulate matter (PM) in the UK in spring 2014 was widely associated in the UK media with a Saharan dust plume. This might have led to over-emphasis on a natural phenomenon and consequently to a missed opportunity to inform the public and provide robust evidence for policy-makers about the observed characteristics and causes of this pollution event. In this work, the EMEP4UK regional atmospheric chemistry transport model (ACTM) was used in conjunction with speciated PM measurements to investigate the sources and long-range transport (including vertical) processes contributing to the chemical components of the elevated surface PM. It is shown that the elevated PM during this period was mainly driven by ammonium nitrate, much of which was derived from emissions outside the UK. In the early part of the episode, Saharan dust remained aloft above the UK; we show that a significant contribution of Saharan dust at surface level was restricted only to the latter part of the elevated PM period and to a relatively small geographic area in the southern part of the UK. The analyses presented in this paper illustrate the capability of advanced ACTMs, corroborated with chemically-speciated measurements, to identify the underlying causes of complex PM air pollution episodes. Specifically, the analyses highlight the substantial contribution of secondary inorganic ammonium nitrate PM, with agricultural ammonia emissions in continental Europe presenting a major driver. The findings suggest that more emphasis on reducing emissions in Europe would have marked benefits in reducing episodic PM2.5 concentrations in the UK

Review and analysis of fire and explosion accidents in maritime transportation

The globally expanding shipping industry has several hazards such as collision, capsizing, foundering, grounding, stranding, fire, and explosion. Accidents are often caused by more than one contributing factor through complex interaction. It is crucial to identify root causes and their interactions to prevent and understand such accidents. This study presents a detailed review and analysis of fire and explosion accidents that occurred in the maritimetransportation industry during 1990–2015. The underlying causes of fire and explosion accidents are identified and analysed. This study also reviewed potential preventative measures to prevent such accidents. Additionally, this study compares properties of alternative fuels and analyses their effectiveness in mitigating fire and explosionhazards. It is observed that Cryogenic Natural Gas (CrNG), Liquefied Natural Gas (LNG) and methanol have properties more suitable than traditional fuels in mitigating fire risk and appropriate management of their hazards could make them a safer option to traditional fuels. However, for commercial use at this stage, there exist several uncertainties due to inadequate studies, and technological immaturity. This study provides an insight into fire and explosion accident causation and prevention, including the prospect of using alternative fuels for mitigating fire and explosion risks in maritime transportation

Data integration for offshore decommissioning waste management

Offshore decommissioning represents significant business opportunities for oil and gas service companies. However, for owners of offshore assets and regulators, it is a liability because of the associated costs. One way of mitigating decommissioning costs is through the sales and reuse of decommissioned items. To achieve this effectively, reliability assessment of decommissioned items is required. Such an assessment relies on data collected on the various items over the lifecycle of an engineering asset. Considering that offshore platforms have a design life of about 25 years and data management techniques and tools are constantly evolving, data captured about items to be decommissioned will be in varying forms. In addition, considering the many stakeholders involved with a facility over its lifecycle, information representation of the items will have variations. These challenges make data integration difficult. As a result, this research developed a data integration framework that makes use of Semantic Web technologies and ISO 15926 - a standard for process plant data integration - for rapid assessment of decommissioned items. The proposed solution helps in determining the reuse potential of decommissioned items, which can save on cost and benefit the environment

Isolation thermique et acoustique des bâtiments: réglementation, produits, mise en oeuvre

Les impératifs d’efficacité énergétique et de confort acoustique dans les bâtiments entraînent de nouvelles réponses constructives et une évolution considérable des matériaux et procédés d’isolation. Tenant compte des derniers DTU parus, ce guide regroupe dans un même volume l’essentiel des dispositions techniques de mise en oeuvre des systèmes d’isolation thermique et phonique des bâtiments. Ainsi cet ouvrage : • apporte l’éclairage nécessaire à la compréhension des réglementations thermique et acoustique ; • définit les exigences à atteindre concernant l’isolement aux bruits aériens intérieurs et extérieurs, les niveaux de bruits de chocs et d’équipements, ainsi que le traitement acoustique des parties communes ; • détaille les techniques d’isolation des toitures étanchées et des couvertures ; • décrit l’isolation thermique des murs par l’intérieur et par l’extérieur. Ce manuel pratique est destiné aux maîtres d’ouvrage et promoteurs qui y trouveront une synthèse des exigences réglementaires, et aux maîtres d’oeuvre, architectes et entrepreneurs qui s’en serviront comme d’un aide-mémoire rassemblant les données utiles pour leurs opérations

Scantling Optimization of Ship Structures Considering Fatigue at the Early Design Stage

peer reviewedABSTRACT: Fatigue aspects are leading criterion for the scantling optimization of ships structures. LBR-5 software is an integrated package which performs, at the early design stage, cost and/or weight optimization of ships structures (scantling). This software takes into account structural constraints (yielding, buckling, displacement, ultimate strength). Until now, the fatigue failure issue was not implicitly included in the optimization loop. At the early design stage, limited information and details are available. Therefore simplified methods have to be applied. LBR-5 software provides the nominal stress, so chosen procedure uses the nominal stress and the Miner’s rule. This approach requires a library of stress concentration factors for predefined typical structural details. The goal of the present work is to develop a tool for fatigue assessment that can be integrated on LBR5 optimization process, to realize global optimization taking into account the fatigue issues. Until now, the integration of the fatigue tool is not finished. Only fatigue verification on the optimized structure is possible. On the present paper, the procedure adopted is presented and a longitudinal scantling of the mid-ship section of a LNG is optimized with LBR-5. Production cost is considered as objective functions. The optimized scantling is checked by the fatigue tool. The fatigue criterion is not respected on some panels. Corrections are performed on these panels to have an optimized scantling without fatigue problems

Squall: Nightmare for Designers of Deepwater West African Mooring Systems

ABSTRACT Squalls have been present in the environmental specifications for floating units in West Africa for the last couple of years. However it appears that such phenomena tend to be the designing factor for mooring systems of deepwater FPSO's (in spread or turret configuration) and offloading buoys. At that stage, due to the lack of proper modelling/characterisation, squalls tend to be represented for design purposes by on-site recorded time series of varying wind velocity and associated relative headings applied from any direction. This leads to rapid changes in offsets and loads in the mooring lines induced by the transient response of the vessel to sudden load increase generated by such squall signal. Through diverse exemplary simplified calculations, this paper illustrates the influence of the consideration of squalls in the design process, together with the present shortcomings in the modelling process, either in terms of extreme conditions, or in terms of operating conditions, knowing that such events are difficult to forecast. In addition the effect of tugs, and associated operating limitations are also discussed. Areas needing further investigation are finally identified.
