Marine activities in deep water and harsh weather conditions

Abstract

Objective of presentation:<uli>

<li>Of particular concern is the difference between short-term activities, which can be conducted within a good weather forecast period, and activities that take longer time, or may be regarded as a permanent activity. </li>

<li>First, a discussion of short-term marine activities will be given, emphasizing aspects specifically related to deep water, such as the positioning and the effects of resonant motions of vessels in waves.</li>

<li>After that, deep-water marine technology will be discussed in case of harsh weather. Reference will be made to typhoons, with emphasis on the possibility of aborting operations.</li>

<li>For permanent activities, the need for robust design is emphasized to ensure that the facilities can withstand the strongest typhoon situations.</li>

<li>The presentation will be finalized with a discussion of the selection of safety level (return period for extreme weather events), with a challenge to consider the effect of climate change and the possibility of more frequent extreme Typhoons. </li>
