Abstract The 2014 Wood Review is a report reviewing UK offshore oil and gas recovery and its regulation, led by Sir Ian Wood. The report identifies and addresses key challenges in the UK petroleum industry, among them the lack of a strong regulatory body and a decommissioning strategy. The UK petroleum industry is mature, and Norway may benefit from UK's experiences in decommissioning. The article investigates the applicability of the Wood Review recommendations for decommissioning in Norway. The analysis of the recommendations in the Wood Review is carried out by a SWOT-analysis of the general recommendations with a high potential impact on decommissioning as well as the five recommendations specific to decommissioning. The recommendations in the Wood Review were broadly accepted by UK authorities and formed the basis for numerous initiatives aimed at improving policies and practices in UK decommissioning. The key initiatives are presented to illustrate how the Wood Review recommendations has been interpreted. A summary of the key differences between the petroleum industries and the regulatory authorities in Norway and the UK is provided for background. Decommissioning in Norway face similar challenges to those identified in the Wood Review. The analysis indicates that several of the UK initiatives following the recommendations in the Wood Review has the potential of improving decommissioning in Norway. Differences in regulatory regimes between the regions may complicate the implementation of some of the initiatives following the Wood Review in Norway. In most cases only minor changes to regulations and/or practices are required. Recent UK initiatives with a high impact on decommissioning include increased focus on sharing of information and lessons learned, increased collaboration, the development of a decommissioning strategy, benchmarking of decommissioning cost estimates for all projects and the development and publishing of annual UK decommissioning cost estimates. There are indications that the Norwegian Petroleum Directorate (NPD) and the Norwegian Ministry of Petroleum and Energy (MPE) are falling behind their UK counterparts in key areas. Norway has limited experience with decommissioning, and scrupulous analysis of lessons learned in other regions is essential. Decommissioning of Norwegian offshore infrastructure is a major undertaking and even minor improvements may have a substantial impact on personnel risk, risk to the environment or the total decommissioning expenditure. The Norwegian regulatory regime has been an integral part of the Norwegian petroleum industry's success in previous decades, and changes to the regime require careful deliberation. The recent implementation of initiatives aimed at improving decommissioning regulations and practices in the UK represents a unique learning opportunity for Norwegian authorities. The analysis suggest that Norway may benefit from adopting some of the UK initiatives following the Wood Review recommendations.

That the oil and gas exploration and development is extending into deep water proceeds the rapidly shift to subsea production system. However, complex subsea equipment and frequency offshore accidents aroused the concern on the risk assessment of subsea system. The paper illustrates the hazard aspects which should be focused on in the subsea equipment compared with the surface equipment. The hazards identification and risk analysis on subsea X-tree system is carried out. A general risk-prevent process of subsea X-tree system is illustrated, so does the reliability analysis process. Besides, some commendations on subsea detection and maintenance are presented in the paper.

The development of LNG project infrastructure for exclusive use in relation to LNG projects in Australia has placed an enormous strain on and demand on human and manufactured resources. It has undoubtedly contributed to project delay and cost blow outs, and these have had an effect, along with the falling price of oil and LNG, of putting in jeopardy the development of further LNG projects in Australia. Tie-ins and joint development may be one way to de-risk and enhance the economic viability of developing future oil and gas resources through the following means: reducing project delays by using existing developed facilities without the need for extensive pre-FEED and FEED work; reducing the number of government approvals required by using existing facilities that already have relevant government approvals; reducing the unit cost of production by using underused facilities or expanding existing facilities at a marginal additional cost to cater for the additional demand and use; and, reducing exposure to workforce related issues, which have adversely affected the LNG projects in Australia, including unionised workforces, skill shortages and occupational health and safety risks. There are some key issues however, that need to be considered before embracing this approach, which includes: Capacity—the availability of capacity in existing infrastructure which is constructed with an individual project in mind will need to be assessed. Distance—the geographical location of projects can be prohibitive, unlike in other jurisdictions such as the UK North Sea. Loss of control—operators and the majority of participants may no longer be able to dictate development programs and project schedules. Pre-FID work—the access agreements need to be finalised and agreed pre-FID and will need to be front-ended at a time when not all issues are foreseeable. Tolling price—the price needs to be reasonable, yet reflective of the risk taken by the asset owner in allowing third party access and relinquishing some control. The author will explore these considerations and how some of these issues can be addressed in legal matters, as well as the way other jurisdictions have sought to use infrastructure sharing arrangements and the different ways government has influenced infrastructure sharing.

Healthcare associated infections represent a major ongoing cost to health services. This chapter reviews the development and deployment of Ward Off Infection, a serious game targeted at improving infection control practices of nurses in on-the-ward training. The game was deployed in 2009 across 13 hospital wards within the UK. As limited usage of the game precluded attempts to consider its efficacy though pre and post-survey, this chapter focuses upon the key issues surrounding this low uptake. Relating these more generally to the deployment of serious games in healthcare, a potential link is observed between the presence of training professionals and usage of the game, as well as strong overriding perceptions of the medium and training objectives by users. The findings demonstrate the challenges associated with enacting effective behavioural and attitudinal change through a serious game deployed in an on the ward context, particularly with respect to stimulating high levels of perceived usefulness. Hence, the authors reflect on key lessons learned in the development and deployment of Ward Off Infection, and relate their findings to other studies of serious games in healthcare, identifying the context in which a game is deployed to be a critical development consideration.

This paper provides a brief overview of the Environment Protection and Biodiversity Conservation Act 1999 (the Act) with respect to the upstream petroleum industry and focusses on the aspects of assessments and approvals under the Act.The inception of the Act on 16 July 2000 has created a new environmental assessment and approval regime at the Commonwealth level. No longer are proposals referred for assessment on the basis of government decisions, but on the basis of the potential for a proposal to impact upon a matter of National Environmental Significance (NES). Examining the statistics of referrals made, controlled actions determined and approvals granted, provides a useful guide as to the types of activities that are captured by the Act. This exercise is particularly valuable for the oil and gas sector.With more than 20 of the referrals received from the petroleum sector being determined to be controlled actions (that is, actions that are likely to have a significant impact upon matters of NES), a review of the assessment and approval processes under the Act provides some useful insights into what factors to consider when seeking approval under the Act. In particular, information on the timeframes involved, extent of information required, form and scope of approval conditions and synergies with other approval requirements provide valuable insights to proponents and can assist in planning future activities in a manner that is consistent with both the requirements of the Act and those of the proposed action.This paper identifies key issues and lessons for proponents when seeking approval under the Act and also identifies areas where industry can work closely with the Commonwealth Government in ways to achieve a balance between environmental protection and the continued development of the oil and gas industry.

Abstract In past years, offshore oil and gas accidents have often occurred. Environmental hazards have the capability of turning into very difficult to manage in addition with the modern technology limits and lack of a fail-safe operation that can identify, control and terminate the accidents. However, the offshore crude oil also natural gas search and development is expanding to deep-water and moving promptly to the subsea production systems. (SPS). Though, the complicate subsea equipment material besides frequency offshore disasters stimulated the consideration onto the risk analysis of subsea systems. Detection of the impact of deep-water oil and gas reserves in the subsea production system. However, loss of SPSs can contribute to massive industrial failure, severe natural pollution, and indeed serious disasters. Therefore, the reliability analysis and safety of SPS have turned into a dominant consideration. This study addresses on the hazards and risk conditions which must be concentrated in the subsea machinery associated within surface equipments. Furthermore, the risks identification also the risk investigation onto subsea “Xmas tree” system is brought out. An over-all risk avert procedure of subsea “Xmas tree” system is represented, also the reliability evaluation method. Moreover, several recommendations on subsea production maintenance and detection are given in this research. This paper is reviewing the following section, subsea production system, hazards or risk identification, environmental issues, hydrate problems, corrosion problems, safety issues, risk assessment on subsea “Xmas tree”, reliability issues of a subsea system.
