[Context and motivation] Safety evidence plays an important role in gaining confidence in the safe operation of a system in a given context. For a large system, it is necessary to provide information about thousands of artefacts that might be used as evidence and about the relationships among themselves and also with other safety assurance assets. [Question/problem] Past research has only addressed some needs of traceability in safety-critical systems and thus has not provided a complete picture of safety evidence traceability. Lack of knowledge and awareness of these needs can result in poor evidence management and lead to certification risks. [Principal ideas/results] This paper aims to provide a broad overview of safety evidence traceability needs for practice and its associated challenges. We also propose a safety evidence traceability model, which has been validated with data from real-world critical systems. [Contribution] We discuss the motivation and challenges for safety evidence traceability, and present the various traces that need to be captured and maintained. This information can help researchers to shape future research based on industry needs and can help practitioners to gain a deeper understanding and a wider knowledge of safety evidence traceability, thereby facilitating safety assurance and certification. © 2014 Springer International Publishing Switzerland.

This paper aims at highlighting the most significant aspects of the present and upcoming environmental regulations in the maritime field: from the already adopted requirements on NOx, SOx and CO2 in MARPOL Annex VI, to the forthcoming requirements of the Ballast Water Management Convention; from the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (2009), to the EU measures under development and discussion for the Measurement, Recording and Verification of ships’ CO2 emissions. The paper also touches upon how the new regulations will affect the design and operation of ships and what are the new technologies available on the market. © 2014, Accademia Nazionale dei Lincei.

The paper presents the design of two prototypes of a hull monitoring system which employs temperature compensated laser based optical sensors. The prototypes have been developed for a double side bulk carrier and an ice class tug boat. A set of finite element calculations has been carried out for defining the optimum sensor's installation areas in each ship. Preliminary tests on the algorithms developed for the software onboard and a first analysis of a set of data measured on the tug boat are reported. © 2011 Taylor & Francis Group, London. Source

This paper describes the method used by the Italian Classification Society RINA to develop new Rig Certification Rules. These Rules have been mostly based on failures observation, and their starting point has been a systematic study of dismastings occurred on boats of various types and sizes. Examining many of these events, typical collapse modes have been identified, and specific solutions have been proposed. Within this study a first attempt to a novel rig "dynamic" structural assessment has been developed taking advantage of a new integrated (CFD+FEM/FEA) analytical tool. Theoretical analyses have been compared with experimental data collected during extensive sailing tests on board a 94ft yacht. © 2013: The Royal Institution of Naval Architects. Source
