Cruise ships often transit the littoral zone of developing countries where piracy thrives. The attack against Seaborne Spirit on November 5, 2005 was countered successfully by the ship's crew but the toll could have been a lot heavier that day. Nowadays, although international forces police high-risk waters, the risk map is constantly evolving, and there have been instances where even naval vessels had to change their route in order to avoid perilous areas. In the Seaborne Spirit attack approximately 100 miles off the Somali Coast, although the crew thwarted the pirates from coming any closer to the ship, the assailants managed to launch a rocket-propelled grenade (RPG) that miraculously failed to explode when it hit the ship's side. This paper carried out the analysis of blast and impact in a fluid-structure interaction model with LS-DYNA solver. The aim of the present paper is to investigate the ballistic response of cross-stiffened panels, commonly used in ship and offshore structures, from the impact with an RPG warhead. It was found that although an RPG alone cannot threaten a highly redundant structure as a ship or an offshore platform, the developed jet from the shaped charge is certainly threatening to passengers and crew. © 2011, American Society of Naval Engineers.

Child Abuse Review | Year: 2010
Abuse in residential childcare has been of concern to the public and the profession for a number of years. This article highlights a Scottish Institute for Residential Child Care's (SIRCC) response to the Scottish Government which was requested following allegations of abuse in Glasgow City Council's Kerelaw residential school and secure unit. It offers priority actions to address the challenges of residential childcare and ensure the safety of children and young people as far as is practicably possible. It contextualises the residential childcare task, and explores four interrelated areas in which change is strongly recommended: (1) organisations' cultures; (2) workforce challenges including the status of the sector, staff selection standards, the role of residential childcare workers in relation to their level of autonomy and their education levels; (3) abuse allegations, in particular the sector's growing fearfulness of false allegations, support for practitioners' anonymity when accused of abuse and a reconsideration of criminal record certificate information; and (4) service delivery related to behaviour management and advocacy support. The intersection between the SIRCC and the subsequent Kerelaw Inquiry reports is outlined. Finally, it concludes with a scan of the immediate strategic policy horizon which indicates an unprecedented momentum for change. While based in the Scottish context, it reflects lessons which are applicable internationally. © 2010 John Wiley & Sons, Ltd.

The paper presents detailed results of a comprehensive analysis pertaining to Aframax tanker incidents and accidents that occurred in the last 26 years. The thorough review of the captured accident database information and the analysis of the historical records provided essential qualitative and quantitative information on a variety of parameters relevant to risk-based methodologies, namely the degree of severity and frequencies of accidents broken down into the pre-1990 and post-1990 periods, the spilled tonne rates and the impact of hull design and of ship's age, particularly on non-accidental structural failure accidents and geography of worldwide oil spills. The generated information enables conclusions on Aframax tanker accidents and of tankers in general to be drawn, for further exploitation in risk based design, operation and regulations. © 2007 Institution of Mechanical Engineers.

Local Environment | Year: 2010
This article is concerned with the nature and significance of inequality in the environmental experience of children and young people. We argue that research in this area needs to widen in perspective and address a complex set of environmental attributes that matter to children and young people, and to their development. Discussing a study conducted in three differing locations in Scotland, the paper examines the local places that were important to children and young people, and the factors that affected the benefits they derived from them. The results illustrate that unequal experiences arise partly through different material provision of environmental goods, but also issues of quality and maintenance, and that relational dynamics have a crucial role. An important concern is not just the quality of experiences in the present, but the effects that environmental experiences in early life have on skills and capacities taken forward into adulthood.© 2010 Taylor & Francis.

The work presented in this paper focuses on the CFD application of large eddy simulation (LES) and detached eddy simulation (DES) to the prediction of the forces acting on an International Americas Cup Class yacht keel model exposed to uniform incident flow at turbulent Reynolds number regime. The simulations were performed using both methods on adapted unstructured grids. The model keel used in the current study was developed by Chalmers University for experimental purposes, and is used for validation of CFD codes in yacht hydrodynamics. Initial results obtained are compared and validated against existing experimental data from wind tunnels in terms of lift and drag coefficients measurements and wake flow observations behind the keel. Two sub-grid scale models for LES and two turbulence models for DES are investigated and compared. Sensitivity to numerical parameters is also addressed. Overall, qualitative results and predictions are satisfactory and quantitative findings agree and fit well with the experimental values although error in forces prediction is high in some cases. © 2012 Elsevier Ltd.
