“…The risk posed by potential fires and explosions on road can be controlled by providing adequate separation distances between road and facility site or individual roadside objects (process units, say). An employment of separation distances is a part of wider safety strategies known as facility sitting and land use planning (CCPS 2005;Cahen 2006;Cozzani et al 2006;Taveau 2010, Nagashima et al 2011. However, the cost of land acquisition for a provision of future road-to-facility separation distances can be unacceptably high.…”

“…The addition of Ni to steel usually causes solid-solution softening at low temperature, which is considered to improve the cryogenic toughness of steel [5]. However, Ni is cost-intensive [6], so Ni-reduced cryogenic steel containing 5% Ni has been recently developed [7].…”

The 5% Ni steel is often used to make steel storage tanks to store liquefied natural gas (LNG). Herein, the microstructure and mechanical properties of 5% Ni steel samples during bending were studied through combining scanning electron microscopy, energy dispersive spectroscopy, optical microscopy, X-ray diffraction, and electron backscattered diffractometer methods with tensile tests. The outer and inner arcs underwent tensile and compressive stress, respectively, resulting in a severely deformed microstructure with a high density of dislocation, improving both the tensile and yield strengths. The ductility of the 5% Ni steel samples decreased significantly after bending due to the work hardening and dislocation accumulation. During bending, the shear bands occurred at the surface or subsurface, which were caused by strain localization. Amounts of “harder” grains with high TF and more orange and red KAM areas with high local strain at the outer and inner arcs produced a greater stress concentration than that of the mid-thickness, which can induce crack initiation and propagation due to the large deformation during bending.

An early stage of the design of a safety barrier intended for protecting roadside property against fires and explosions on road is studied. Three main problems of this design stage are highlighted: determination of the road segment from which a roadside object to be protected can be damaged; specification of area for barrier construction; and positioning of the barrier within available construction area. A solution of these problems is considered to be a necessary step providing helpful information for a detailed design of the barrier by applying methods of structural optimisation. It is shown that the most challenging problem of the early stage of barrier design will be the determination of an unsafe road segment. This problem is formulated as a problem of quantitative risk assessment (QRA) and solved by combining rigorous methods of QRA and structural reliability theory. Apart from rigorous methods, engineering judgement may be required for the positioning of the barrier within available area. A case study is used to illustrate the main steps of the early, pre-optimisation stage of barrier design.
