Island Engineering, formed in 1999, is dedicated to design and engineering support of high performance marine vehicles- primarily for the development of advanced ride control systems. These systems are analogous to an aircraft flight control system. Unlike traditional fin roll stabilization systems, a ride control system often reduces dynamic variations in pitch, roll, yaw and/or heave motions simultaneously- while concurrently maintaining list, trim, heading or height above the surface at user-defined values. Proper design and implementation of the entire integrated system, from the effectors and their servo dynamics to the main control algorithm software, is essential in achieving the highest possible performance.
Island Engineering personnel employ 3D CAD/CAM, Algor FEMPRO FEA with MES, plus various vortex lattice and panel based CFD analysis tools to optimize the effectors for these systems. Sea-keeping simulations, model tests, a vast experience base and scientifically performed sea trials are also used to refine system parameters.
The most advanced IEI motion stabilization system, fielded jointly with Quantum Marine Engineering of Florida, is currently installed on the U.S. Navy’s LSC(X) ‘Sea Fighter’. The system consists of two actively controlled titanium ‘T’ foils mounted near the bow, two active transom interceptors, and two actively controlled flapped skegs for yaw control. System components are linked via an EMI resistant fiber optic LAN.
‘Spectrum’ systems can be provided for vessels of all types in the 50-300’ range. IEI recently installed yacht trim tab systems on a 56 Ft monohull, as well as a 65 Ft catamaran built by Multihull Technologies in Florida.
