Simulation Environment for Risk Assessment of E-Navigation Systems

“Safe voyage from berth to berth”: This is the goal of all e-Navigation strains, driven by new technologies, new infrastructures and new organizational structures on bridge, on shore as well as in the cloud. To facilitate these efforts suitable engineering and safety/risk assessment methods are required. Understanding maritime transportation as a sociotechnical system allows the usage of system-engineering methods. Simulation based test beds for verification and validation of e-Navigation technologies are important methods to obtain functional safety and reliability [1]. The modelling and simulation toolset HAGGIS is a co-simulation system for evaluation of e-Navigation concepts and systems. It provides a maritime traffic simulator and a physical world (n-body) simulator and services for finding rare events of failures. HAGGIS is accompanied by the physical test bed LABSKAUS which implements a reference port and waterways. This paper describes an integrated and seamless approach for developing new e-Navigation technologies starting with virtual simulation based safety assessment and ending in physical real world demonstrations. It gives an overview of the actual test bed and introduces requirements, concepts and elements of HAGGIS and LABSKAUS, which are joined in the eMIR test bed.
