The STM Master Plan provides a feasible transition sequence to realise the STM Concept in order to reach the performance targets and turn the vision into reality. This plan is also described in the e-Master Plan (stmmasterplan.com) which is a tool that will be updated continuously for the interactive dissemination the STM Master Plan to the industry. Whereas the STM Target Concept is describing the final goal of how STM will transform the Maritime industry, the STM Master Plan is the guide to those stakeholders that will be essential to the fulfilment of the STM vision, what actions and efforts will be needed and not least, what effects and operational improvements can be expected for their businesses and at what point in time it generates business value. A first important step in ensuring the successful deployment of STM is the STM Validation Project where the STM concept will be tested and evaluated in large test beds. The STM Master Plan is made up of three phases of transition, improvement phases, reflecting the incremental approach that is proposed for the introduction of STM · Creating the foundation (2015-2020) · Increasing operational capabilities (2020-2025) · Achieving full STM capability (2025-2030). The first improvement phase will initially be delivering proof of concept of the real effects of STM through the STM Validation Project to the industry. The early introduction of route exchange in a standardised format will give immediate effects on safety and efficiency when the route can be exchanged with shoreside actors and nearby ships. At the same time, introduction of Port CDM will contribute to early effects in the efficiency of ports and standards such as Unique Voyage ID and Maritime Actor Identities will be introduced to the industry. Further, the initiation of governance processes and bodies of STM will speed up the involvement and engagement of the industry in STM. In the second improvement phase a maritime information sharing platform, SeaSWIM, is being established with full functionality. The different actors in the industry are now, directly or through their system suppliers, connected to the information-sharing infrastructure. The fact that all relevant information of the voyage now is available through SeaSWIM will create new services that automatically will provide port states, coastal states etc. with mandatory ship reporting information. It will reduce the administrative burden for the officers on board significantly. This also means that stakeholders along the transport chain can be notified much earlier regarding their involvement in a specific voyage, thus extending the planning horizon. Port CDM enabled ports will be able to provide synchronisation services for approaching ships, enabling just-in-time arrival, reducing waiting time at anchor. The adjustment of transport contracts as a result of the possibility of arriving just in time will start to generate substantial savings in bunker consumption and reducing environmental footprint of shipping. In the third improvement phase the full potential of the envisioned STM is presented. We will have achieved a functional eco-system of information providers and consumers and as a result new services will be offered. The federated model of governing common resources, such as SeaSWIM and various standards will be in place. Furthermore, the maritime ecosystem has been omplemented with a large number of new actors, creating new knowledge and services out of information that was not possible to share in a structured way before STM. The deployment strategy describes the path for rolling out the concept and is based on a number of assumptions on how the STM Master Plan can be deployed. The strategy describes an approach that builds more on voluntary participation, driven by incentives and benefits, rather than a mandated approach. It recognises the fact that STM gives different benefits to different stakeholders and segments of shipping. Further involve IMO and IALA in the future development is important and a key factor for taking STM from a European to a global perspective. Proving benefits, and ensuring stakeholder buy-in, have also been identified as important factors for the successful realisation of STM in the STM Master Plan risk management. The STM Master Plan identifies the need for a number of research, development,validation, and demonstration activities, addressing different parts of the STM concept. In order to achieve a long-term solution, and a well-coordinated development the STM concept, it needs to be under constant development. The Master Plan is a tool that requires governance. The vision is for this to be adopted by a future European Economic Interest Group, EEIG, which will provide STM with a permanent structure and secretariat function for further development and deployment.
