The first in a projected series of GREENER conferences was held in Dublin during September 2019, and drew scientists, innovators, industrialists, and decision makers to share developments and thoughts on offshore energy machines and devices. The 11 papers in the proceedings explore such topics as on the Coriolis effect for internal ocean waves, a review of rapid distortion theory, consistent modal calibration of a pendulum-type vibration absorber, frequency-domain identification of radiation forces for floating wind turbines by moment-matching, and a study of the Antarctic Circumpolar Current via shallow water large scale modeling.
