Although maritime transport is the backbone of world commerce, its digitalization lags significantly behind when we consider some basic facts. This work verifies the state-of-the-art as it currently applies to eight digital domains: Autonomous vehicles and robotics; artificial intelligence; big data; virtual reality, augmented and mixed reality; internet of things; the cloud and edge computing; digital security; and 3D printing and additive engineering. It also provides insight into each of the three sectors into which this industry has been divided: Ship design and shipbuilding; shipping; and ports. The work, based on a systematic literature review, demonstrates that there are domains on which almost no formal study has been done thus far and concludes that there are major areas that require attention in terms of research. It also illustrates the increasing interest on the subject, arising from the necessity of raising the maritime transport industry to the same level of digitalization as other industries.

Conceptual design of PSV ship with hybrid diesel electric-FC power plant is presented. Two methanol-fed 250 kW SOFC systems are installed on board with 21 days autonomy. Cogeneration heat from SOFC allows answering hot water needs on board. Optimized hull design allows sailing with SOFCs and only one diesel generator. At ECO-Speed operation mode pollutant emissions are notably reduced. a b s t r a c tNowadays increasing fuel prices and upcoming pollutant emission regulations are becoming a growing concern for the shipping industry worldwide. While fuel prices will keep rising in future years, the new International Convention for the Prevention of Pollution from Ships (MARPOL) and Sulphur Emis-sions Control Areas (SECA) regulations will forbid ships to use heavy fuel oils at certain situations. To fulfil with these regulations, the next step in the marine shipping business will comprise the use of cleaner fuels on board as well as developing new propulsion concept. In this work a new conceptual marine pro-pulsion system is developed, based on the integration of diesel generators with fuel cells in a 2850 metric tonne of deadweight platform supply vessel. The efficiency of the two 250 kW methanol-fed Solid Oxide Fuel Cell (SOFC) system installed on board combined with the hydro dynamically optimized design of the hull of the ship will allow the ship to successfully operate at certain modes of operation while notably reduce the pollutant emissions to the atmosphere. Besides the cogeneration heat obtained from the fuel cell system will be used to answer different heating needs on board the vessel.

Key analysts are emphasizing the importance of the digitalization especially of the supply chain. This work aims to improve maritime shipping companies by introducing digitalization in their operations. This objective is achieved analyzing the impact of maritime container shipping companies’ digitalization. This analysis requires as input the Business Process Model (BPMo) and an inventory of digital applications to verify how the BPMo changes when deploying the applications, define the prerequisites necessary for this deployment, and identify the key performance indicators (KPIs) to track it. The impact of the deployment of the applications has been quantified by using four performance dimensions: Costs, Time, Quality, and Flexibility. The results show that the impacts are different per application, with changes in the processes, the addition of new ones, and the decommissioning of others. The impact of digitalization is high when trying to deploy all the applications at the same time. Companies can leverage this work, which requires reviewing the documented impacts in their processes and the applications’ prerequisites as well as updating their existing balanced scorecard, incorporating the application’s KPIs. A list of 10 applications has been identified as “quick wins”; then, applications can be the starting point for digitalizing a company.

The main objectives of this paper are the analysis of the modeling problems for the dynamic behavior of moored devices for marine tidal energy harnessing and the solutions proposed for the GESMEY generator. The paper has been divided in four parts: the analysis of the energy resources and the state of the art of the technologies used for their exploitation, the description of the GESMEY generator, the modeling problems for this kind of devices and, finally, some examples of the dynamic behavior of the GESMEY generator.
