Abstract

The LAURA JIP (LAUnch and Recovery system for Any small navy craft) is developing a naval Launch and Recovery (L&R) standard which will allow ships from various Navies to exchange small Rigid Hull Inflatable Boats (RHIBs) with each other. It is vital that the safe operating limits of these L&R operations are fully understood. To support this understanding, a numerical modeling capability is being developed. The LAURA JIP will develop this numerical simulation capability through: (1) a hybrid simulation environment whereby the various aspects of the L&R process will be modeled using various numerical tools and (2) a time domain seakeeping program that appropriately accounts for the hydrodynamic interaction effects that occur during L&R evolutions, including the effect of the boat rope. To assist in the validation of these numerical tools, a series of scaled physical model tests have been undertaken. These tests include: (1) captive planar motion maneuvering tests of two different RHIBs, (2) towing tests of a RHIB in calm water and waves, with and without a lifting line, (3) captive and free sailing tests of a mother ship to measure the diffracted and radiated waves in close proximity to the mother ship as a function of wave and sailing conditions and (4) an extensive set of tests with a RHIB towed from the mother ship to record the motions of both vessels as well as tow line forces.
