Expert Witness MarineMr. W.P. (Bil) Stewart, C.Eng., D.OE (click for resume) President of Stewart Technology Associates (STA) has provided expert testimony in many marine and offshore litigation cases. These cases have involved vessel collisions, vessel sinkings and groundings, vessel capsizes, production platform toppling, barge buckling, major structural damage to jack-ups under tow, jack-up elevated failures, anchor failures, and mooring system failures. Mr. Stewart has provided expert opinions for cases in the United States, in the United Kingdom, and in South Africa. He became a registered Professional Engineer (Civil Engineer in Texas in 1983) and a Chartered Engineer in Europe (Naval Architect, 1977). Mr. Stewart became a Board Certified Engineer, D.OE, (Diplomate of Ocean Engineering, by ACOPNE, ASCE, in 2013). Numerous technical papers and articles have been written by Mr. Stewart, who is also closely associated with the activities and research undertaken by several learned societies, particularly the Society of Naval Architects and Marine Engineers, and the American Society of Mechanical Engineers. A broad background in Civil Engineering, Soil Mechanics, Hydrodynamics, Offshore Structures and Structural Dynamics, Mechanical Engineering and Naval Architecture, enables STA to provide a wide and well balanced service to lawyers. Many legal cases, especially those involving forensic examination of accidents, require knowledge and experience spanning several of the above technical disciplines. STA produces high quality technical reports including clear diagrams which enable the technical analyses to be easily understood. Extensive use is made of computer software and state-of-the-art analytical and simulation techniques. Almost invariably a color “notebook” computer and printer accompany Mr. Stewart when he attends (or provides) depositions, visits clients’ offices, or simply travels out of town. With this computer, reports can be immediately modified, new analyses performed, existing analyses revised, and hard copy provided anywhere in the world, offshore and onshore. Technical reports produced by STA have won clients millions of dollars over the last fifteen years. In addition to a wide range of technical analysis software, STA maintains computer databases of offshore and marine accidents, tanker oil spills, plus databases of construction and other offshore costs. These, and other databases, can be most useful in maritime litigation. STA also produces graphic visual aids and physical models for use at trial. Expert testimony work is a small but important part of the normal STA workload.
