One Sea is a high-profile ecosystem with a primary aim to lead the way towards an operating autonomous maritime ecosystem by 2025. The collaboration led by DIMECC Ltd. gathers together leading marine experts and is a strategic combination of top research, state-of-the-art information technology and business. The work began in 2016, and the aim is to create an environment suitable for autonomous ships by 2025. The companies and organizations collaborating in the ecosystem are forerunners in their respective fields and the knowledge they share sets them apart from other likeminded projects. The founding partners include ABB, Cargotec, Ericsson, Rolls-Royce, Meyer Turku and Tieto and Wärtsilä. The ecosystem ensures a well-researched, tested and highly capable autonomous shipping network. The focus is to create solutions that take advantage of the lower capital and operating expenditure – with the better efficiency, reliability, safety and sustainability – that digitalization has brought into other areas of business and industry. The co-creation ecosystem will also set the course for new industrial standards. With the leadership, participation and steering from the One Sea Autonomous Maritime Ecosystem, the new standards will correspond with the targets of minimizing accidents, decreasing the environmental footprint of marine traffic, and advancing possibilities for new commercial ventures. DIMECC stands for Digital, Internet, Materials and Engineering as well as Co-Creation. In One Sea DIMECC gathers key players of the marine industry in an ecosystem that speeds up the development process by bringing innovations to market faster.
