Innovations in Maritime Technology and Engineering presents a collection of papers in two volumes from the 8th International Conference on Maritime Technology and Engineering (MARTECH 2026), held in Lisbon, Portugal, on 27-29 May 2026. MARTECH 2026 represents the eighth edition of an international conference series originating from a set of biannual national conferences in Portugal and has progressively evolved into a major international event, reflecting the increasing globalization of the maritime sector and its wide range of activities. These volumes contain 185 peer-reviewed contributions, all evaluated by an International Scientific Committee, covering recent research and developments in maritime engineering and technology.The two volumes focus on several key areas, including: Ship design - hydrodynamics, motions and waveloads, manoeuvring, propellers, energy efficiency, hydroelasticity, structures, composites, machinery and alternative fuels, small vessels, sensors and equipment; Autonomous surface vessels; Autonomous underwater vehicles; Shipbuilding and ship repair; Maritime transportation and ports; Ship operation - environmental perception, collision risk and avoidance, emissions, carbon capture; Renewable energy devices in ships; Offshore energy resources - photovoltaic, wind, hydrodynamics, waves; Marine environment; Fishing and aquaculture; and Underwater noise. Overall, the proceedings provide a comprehensive overview of current innovations, research trends, and technological developments in the maritime sector.The Proceedings in Marine Technology and Ocean Engineering series is devoted to the publication of proceedings of peer-reviewed international conferences dealing with various aspects of marine technology and ocean engineering. The series includes the proceedings of the following conferences: the Marine Structures (MARSTRUCT) Conferences, the Renewable Energies Offshore (RENEW) Conferences, the Maritime Technology and Engineering (MARTECH) Conferences, the Collision and Grounding of Ships and Offshore Structures (ICCGS) Conferences, and the International Maritime Association of the Mediterranean (IMAM) Conferences.
