Abstract

The paper presents results of a study on the seakeeping performance of a modern Anchor Handling Tug Supply (AHTS) vessel. It assesses the capability of the vessel to operate safely and efficiently in typical open sea conditions, characteristic of the South Atlantic (Brazil). The RAOs for various wave headings, speeds and loading conditions are calculated using the well-established seakeeping 3D panel code NEWDRIFT developed at NTUA-SDL. The vessel's responses for two typical South Atlantic wave spectra are calculated, analyzed and assessed.
