TC-TDG is looking to acquire the services of a contractor to perform an in-depth literature search of ESS types that meet the definition provided in Section 2 and an analysis to determine the appropriateness of their current classification and regulatory requirements for transport. The analysis will be based on hazards due to their possible failure modes, as well as details on the outer casing that directly houses the components of these devices, to determine if gaps exist in current regulatory requirements or classification. The project will include the following components:A literature review to assemble information on the types of ESS currently being transported as well as emerging ESS technologies;details on the regulatory requirements related to the transport, including stowage, of identified ESS technologies aboard enclosed vessels as cargo;a hazard assessment of identified ESS;an analysis of the conformity of the ESS components and hazards with currently applicable UN classification and regulatory requirements, based on data from the literature; andrecommendations to address any identified gaps in the regulatory safety requirements.The study's goal is to obtain an overall picture of the hazards of ESS and examine these hazards in the marine context to identify any gaps that may exist in emergency response considerations or from a regulatory perspective, including the applicability of current UN classification to their transport by the marine mode.
