The offshore oil & gas indus- try, more than ever, needs to know the same thing. MOTISS integrates blast effects and recovery analysis within a single package to assist in survivabil- ity design, design evaluation, require- ments assessment and resource allo- cation. Grounded in Alion’s years of survivability engineering experience, MOTISS answers the need for a rapid and effective evaluation tool. More simply stated; MOTISS-IBA is an integrated safety assessment solution designed for the offshore industry to identify, evaluate and then control po- tential hazards. Unlike Advanced Finite Element Analyses (FEA) or Computational Fluid Dynamics (CFD) whole ship analyses, which are collectively expen- sive, both in analysis time and money, and often only provide the structural response of the vessel to a single “worse case” threat detonation point, MO- TISS lets the user investigate and com- pare the effectiveness of two or more separate survivability enhancement design options and determine which provides the best “bang for the buck.” The user can also manipulate the de- sign, moving system components or plate armor (thickness) to fi nd design changes which have minimal cost or no cost, but which enhance the total survivability of the structure. MOTISS is both a process and a program. It is a process by which a system of systems’ (such as a naval or commercial ship, a building or an oil rig) overall survivability is assessed probabilistically in the event of one or more threats. Using fi rst principle physics coupled with empirical data and tests, MOTISS provides a solu- tion to an event thousands of times, with each test randomly varying the threat parameters and hit location, in order to capture the chaotic nature of the random unknowns. This provides the ability to determine probabilisti- cally, what would, will, or did happen in a similar real world threat event. The user or client can then locate and rank weaknesses quickly in order to allow for corrective action before those weaknesses are exploited in a real world scenario. From their experience in helping the U.S. and South Korean Navies improve vessel survivability, Alion eventually made the leap to transfer that data analysis, technology (and approach) to the offshore world. Cowardin explains, “Following the explosion and loss of the Deepwa- ter Horizon, I started thinking ‘there must be a better way to validate the safety of offshore drilling.’ I started thinking that the complex systems of systems analysis of total ship surviv- ability, as performed for naval ships, might offer the solution. This led Alion to partner with an international drilling company to assess one of its Single-point and root-cause of failure determination Integrated vulnerability and recoverability evaluations First order structural and network system evaluations Fire, fl ooding and threat damage analyses Unbiased survivability design and option comparisons Ballistic, jet, fragment and blast damage analyses MOTISS provides Comprehensive Evaluation and Analysis: www.marinelink.com MN May14 Layout 50-65.indd 59 4/21/2014 10:27:16 AM
