In general, these have a much worse effect on the availability than head waves. For example, if there are cross seas or large differences in wave and current direction, the FSRU and LNGC may be subjected to beam waves. Maximum accelerations, roll angle and pitch angle of critical points on the FSRU Ī critical aspect affecting the reliability of the results is the fidelity with which the metocean conditions are represented.DMA can be used to analyse the fully non-linear motion response of a side-by-side moored LNGC and FSRU for turret moored weathervaning systems, spread moored systems and FSRU’s moored at a jetty. It also accounts for thehydrodynamic interactions between adjacent ships.

We evaluate the motions of a multi-body system in response to winds, waves and currents using our Dynamic Mooring Analysis software (DMA). the probability of any ship touching the seabed in a 25 year period is less than 10%). The result of a typical study is typically a recommendation for the minimum dredged depth of an access channel for a particular safety level (e.g. An example of such a system is PROTIDE (see Bos, Koop & Bolt, PIANC 2011), as applied for the ports of Amsterdam, Rotterdam, Eemshaven, Zeeland (NL), Antwerp (BE), Emden (DE) and Port of Longbeach (USA). A consequence of this is that the required dredging will be less when a sophisticated admission system is applied. The use of a sophisticated admission policy, allows ship access for a higher percentage of the time with a higher degree of safety than a simple system based on a limited number of simple criteria.
