How do you know which of a hundred decisions required to get a 21,000-ton ship through a narrow channel was the wrong one?
S-E-A was contracted by maritime attorneys to evaluate and offer an expert opinion about the activities of a commercial cargo ship transiting the upper reaches of the Houston Ship Channel. The ship was under the direction of a Harbor Pilot with tugboat assistance when an allision (collision with a fixed object) occurred with a concrete pier causing extensive damages to the ship and the pier.
There was no reported failure of the ship's systems and the assisting tugboats were being accused of causing this incident.
S-E-A was provided with a wealth of information that could be used to evaluate the ship's actions. This included: electronic bridge logbook information, voice and data recordings from the ship's bridge, the engine maneuvering electronic data log, GPS track information for the ship, port vessel traffic service “real-time” tracking data, eyewitness reports and incident reports from the ship and tugboats.
Using the information available, S-E-A was able to accurately plot the ship’s track using three-dimensional marine navigation software. This 3-D plot then allowed a comprehensive evaluation of the ship’s rate of advance, and more importantly, its position within the narrow confines of the ship channel as it approached the intended berth.
From the 3-D plot, S-E-A produced a graphical representation of the entire approach of not only the ship but also the assisting tugboats.
Evaluation of test evidence resulted in the following findings:
S-E-A’s ability to accurately evaluate and recreate accidents relies to some degree on expertise using and combining a broad range of advanced technologies. More importantly, S-E-A’s depth of real-world maritime experience allows for the kind of insight and perspective needed to interpret the mass of data that these technologies can generate.
S-E-A’s multi-disciplinary teams are a large part of why we have been able to help so many clients find real answers. The scientific methodologies cross all disciplines and our wealth of experience in solving a wide range of problems is invaluable in assuring broad perspective and thinking unfettered by familiarity and repetition.
