N2 - In this paper, the response and the power absorption ability of the TALOS multi-mode WEC are preliminarily assessed for various environmental and operational conditions, by deploying two different computational tools and assuming linear mooring lines’ behavior. The device consists of an internal sphere attached to its floater with springs and dampers, while power is absorbed through the sphere’s motions relatively to the floater. A comparative study is, initially, conducted assuming rigid connection of the sphere with the floater. Next, by enabling the sphere to oscillate in heave, as well as in both heave and surge, the device’s performance for one and two operational modes is assessed. The two-mode PTO mechanism operation results in an increased power absorption of the device (max mean value of 238 kW) and in insignificant effects in motion responses.
