Choosing a sustainable, economical energy supply system, considering all operational variables of an autonomous submarine dredger: A study as part of the development of the ALERD, which will serve as sustainable coastal maintenance in the service of The Netherlands

The Autonomous Low Energy Replenishment Dredger (ALERD) strives to revolutionize the dredging world. The ALERD operates autonomously underwater, which saves energy during the dredging process and transit. Autonomous underwater operation drives the need of alternative energy facilities. However, due to the energy savings of dredging, alternative...

Exploratory Study on Nuclear-powered Trailing Suction Hopper Dredgers

Dredging is an energy-intensive operation and, due to the nature of the process, there are large and rapid fluctuations in the power requirement. With the signing of the Paris Agreement, implementation of IMO 2020 and expansion of ECAs, the external pressures for the reduction of different emissions(CO2, SO_x, PM, and/or NO_x...
