AWATEA is pleased to announce its 8th Annual Conference


The two-day conference will be devoted to a wide-ranging review of marine energy developments, both in New Zealand and overseas, and includes a popular networking reception at the end of the first day followed by a dinner available to all registrants.

Call for Presentations 

Would you like to be part of New Zealand’s only marine renewable energy event for 2014? Our keynote speakers will be announced shortly and in the meantime we are welcoming presentation proposals based on the conference theme: The Business of Developing Marine Energy. Submissions should be sent to by Wednesday 13 March 2014. The Executive will review the content of sessions and respond as soon as possible whether your presentation has been accepted. It should be noted that speakers will be required to register and pay the appropriate conference fee.

Further details about the event can be found on our Conference page

Wave Forecasting in Support of Offshore Operations

Dr. Sascha Kosleck of AUT University will be speaking tomorrow (Friday 21 February) at NIWA about wave forecasting and its application in offshore operations

Talk Abstract:

We seek to develop a linear, deterministic approach for the just-in-time prediction of an ocean wave field. The work focuses on the forecast of natural sea states as well as wave induced vessel/structure motions based on information gathered from a series of surface elevation snapshots of the surrounding free water surface.  By forecasting the wave train to be encountered by a ship or offshore structure, the wave induced motion behaviour can subsequently be derived – given that the frequency domain transfer functions of the system are known. For cruising vessels, the dependency of the transfer functions on the cruising speed of the vessel is of special interest. The talk will show that new linear methods for the prediction of the motion behaviour of a stationary or cruising vessel/structure deliver excellent results.
