Case Studies

Underway

The X-Craft was designed to demonstrate to the US and other navies the versatility of a very high speed, high payload capability vessel which can cross oceans quickly, and operate in shallow coastal waters on missions which include mine counter measures and antisubmarine warfare.

Building the Sea Fighter
 
Vronay Engineering Services was proud to have been part of the team that designed, built and commissioned the high-speed, littoral surface craft (LSC), the Sea Fighter. Vronay worked with Walther Engineering Services to provide the functions of Engineering Liaison and Owner’s Representative during the 18-months of concurrent design and construction which took place at the Nichols Brother Boat Builders in Freeland, Washington.

The Littoral Surface Craft-Experimental LSC(X) was developed by the Office of Naval Research and christened Fast Sea Frame Sea Fighter (FSF 1) on 5 February 2005. The X-Craft transformational program is a high-speed, aluminum catamaran consisting of an advanced hull geometry, designed to give the craft speeds of 50 knots or more. Initially, she will be used by US Navy, Office of Naval Research (ONR) for purposes of hydrodynamic experimentation and as a test bed for Hull, Mechanical, and Electrical (HME) concepts for the Navy's new class of warship, Littoral Combat Ship (LCS).

In addition to assisting with the day to day resolution of issues which arose between the shipyard force and the owner’s design group, Vronay also organized the drafted procedures for a number of special tests, trials and certifications required before the vessel could be delivered to the U.S. Navy. These included the testing and certification of the flight deck, the shipboard fire suppression system, the propulsion and controls systems and the specialized / purpose-built cargo bay, "X-Y crane".

Vronay also coordinated the installation of a sophisticated on-board collection of sensors and high-speed data acquisition designed by Island Engineering for the Naval Surfaces Warfare Center. The so-called, “Scientific Payload” consisted of more than 1,000 sensors including 300+ strain gages, pressure sensors and gyroscopic instruments.
