PHYSICAL MODEL TEST OF THE MOORED CONTAINER SHIP MOTION AND THE RELATED INDUCED MOORING FORCE
Coastal Engineering Proceedings, 1986 To optimize structure design it is useful to conduct detail physical model tests. Tests of various basic physical phenomena (e.g. resonance problems), reproducing a sea state of prototype duration and then from the behavior of entire structure, the optimal design to the wharf structure will be obtained.

EXPERIMENTAL FORMULA FOR THE WAVE-INDUCED SHIP MOORING FORCE [PDF]
Coastal Engineering Proceedings, 2011 The wave force dose not considered at the formula of mooring ship cable force in the Load Code for Harbor Engineering[JTJ215-98]. This brought the inconvenience to the calculation of designed cable force for mooring ship. By means of analysis for the laboratory model test result of mooring ship cable force under wave effect, Wave force formula of ...

A revolutionary and operational tethered aerostat system illustrating new LTA technology [PDF]
, 1975 An operational tethered aerostat system, which demonstrates utility of LTA systems, is described. It was made possible by development of a reliable tethered aerostat that is used to support broadcast equipment at an altitude of 10,000 feet.

Offshore anchor piles under mooring forces: numerical modeling
Canadian Geotechnical Journal, 2013 A parametric study was carried out to study the behavior of offshore anchor piles under mooring forces in dense sand using a three dimensional (3-D) finite element model (FEM). The Mohr–Coulomb plastic model has been used to model the soil, and has been calibrated based on the centrifuge tests discussed in a Ph.D. thesis (published by Ramadan in 2011).

A new concept for airship mooring and ground handling [PDF]
, 1975 Calculations were made to determine the feasibility of applying the negative air cushion (NAC) principle to the mooring of airships. Pressures required for the inflation of the flexible trunks are not excessive and the maintenance of sufficient hold down
