The specific conditions of the Pacif coast, with high wave energy content, generatea marked impact over moored ships at jetties or buoysystems. Although the usual waveconditionsdo not involve impressive wave heights, the dominant presence of longperiods (between 12 and 25 seconds) causes very significant interaction forces on the moored vessels. Due to these circumstances, high quality simulation models must be used in the dynamic mooring analysis as an essential factor to guarantee the operability and safety of maritime operations.
These analyses allowto optimizea basic design, applying modifications that reduce construction and operation costs or minimize the expected downtime. On the other hand, these studies are mandatory forLNG Terminals with FRSU (regasification vessel) or FLNG (floating liquefaction) technology. In these cases, the ships are moored permanently, for several years, so the mooring system must resist extreme conditions, far beyond those usual in conventional transfer operations.
Siport21 uses varied numerical software to carry out these analyses toapply the most appropriate method in each case. So, specific mooring systems can be defined for a vessel class or thedesign fleetof a terminal.The lecture presented by Siport21 included several representativeexamples of complex situations that have required an in-depth analysis using numerical models: compatibility of a modified berth for a very diverse fleet of oil tankers, problems with “passing ships”, special designs for FSRUs and FLNG barges in demanding environments, excessive movements,and breakage of lines in LNG terminals, simplification of the design of buoy fields, tsunami or tropical storm alerts, etc.
Siport21 presented these studies in the 18thCongress of Oil Maritime Terminal Operators Latam Society (SLOM). The congress brought together operators of maritime-oil terminals to carry out an exchange of knowledge and experiences, as well as the dissemination of new technologies, products, and specialized services in the sector.
More than 20 years’ experience, Siport21 is a maritime and port engineering consultancycompany focused on ship manoeuvring and ship behaviour. Their facilities include a Real-TimeShip Manoeuvre Simulation Center approved by DNV as the only Maritime TrainingProvider in Spain. Until now, they have carried out more than 1.500 projects in 56countries. Also, they havetrained 1.800 seafarers from 50 international shipping companies in their SimulationCenter. From their innovation business line, they have developed several software packages relatedto Safeport© concept and they are involved in the design of new products and servicesaccording to Industry 4.0.
