Program Package "ANCHORED STRUCTURES"
The Program package " Anchored Structures " is designed for modeling of static and dynamics of the floating constructions having anchor systems (AS), under action of wind, current, waves and ice. In structure of a package there are also modules of calculation of loads on stationary sea structures.
The software package allows:
- To set design parameters of AS.
- To set geometric parameters of structures as well as mooring and breaking devices parameters when one or several anchored constructions (up to five) are present.
- To perform calculation of non-linear stiffness parameters (SP) of anchor lines of various types. SP are functions of AS reaction vector from moving object and are used for modeling of objects static and dynamic behavior.
- To perform calculation of static and dynamic (regular and irregular) loads on the considered floating and stationary constructions from wind, currents, waves and ice, and waves - in view of interference of structures (when several constructions are present).
- To perform calculation of hydrodynamic parameters of constructions cases - factors of added masses and of wave resistance.
- To carry out calculation of static and dynamic movement of objects, tension of anchor lines, forces in mooring and breaking devices in three-dimensional non-linear statement.
- To carry out calculation of dynamic movements in both frequency and time ranges.
- To operate the program in interactive (dialogue) mode (set the method of data collection, parameters of spectral and probabilistic analysis, environmental affects).
- To observe, with the help of the graphic support block, objects dynamic behavior from various directions and distances (three-dimensional image) and with different time scale of display.
- To find own frequencies of fluctuations of structures and to make spectral analysis of loads, oscillations of objects and lines reactions.
- To make statistic analysis of amplitudes of objects fluctuations and lines reactions.
- To carry out probabilistic modeling of construction's behavior for the period of its operation.
- The software package can be used for analysis of freely floating, anchored or fixed offshore structures (semi-submergible and TLP - platforms, drilling vessels, pipe-layers, floating cranes, docks, stationary platforms etc.). The software package has the certificate of the Russian maritime register of shipping of computer program type approval and is used by the Russian design bureaus for design of floating anchored structures.
