Mobile Harbor CADET

Subject: Numerical Modeling & Evaluation of Deep-Draft Vessel Vertical Motion for Verification of Channel Design Improvements for Mobile Harbor, Alabama. Description of Supplies/Services: The Mobile District is requesting assistance to apply the CADET (Channel Analysis and Design Evaluation Tool) vessel vertical motion model for studies of Mobile Harbor (Alabama), which are already in-process. The CADET is a numerical model developed for estimation and evaluation of vertical motion and margins for underkeel clearance of deep-draft displacement hulls when operating in the offshore or approach channel environment. Its practical deployment within United States Army Corps of Engineers (USACE) is relatively new with the first instructional workshops being administered only over the past few years. The software was developed with the assistance of the U.S. Naval Surface Warfare Center (Carderock Division or NAVSEA-Carderock) and contains algorithms and logic considered proprietary and as a consequence, it currently cannot be released to the public or private sector. It is also now the preferred and designated software for evaluation of vertical vessel motion by the USACE hydraulic engineering community of practice (COP). Due to the relatively recent release of CADET within USACE via the workshops, there presently are not many District personnel who have had the opportunity to independently use or employ it and become ideally proficient in its use as such efforts often must wait until a project evaluation is needed, application is advantageous, and related work efforts are authorized, scheduled and funded. Currently, assistance has been requested by technical staff of the Mobile District to employ the CADET for evaluations of Mobile Harbor (Alabama). Studies for the Mobile Harbor are already in progress, on critical schedules, and would incur a benefit from application of CADET. The Related needs for this requirement primarily stem from the interim review of a tentative plan formulation and in-process technical review, which uncovered that the influence of wave action in the offshore channel environment should be more thoroughly and carefully evaluated. This determination is based on efforts to ensure that sufficient margins for underkeel clearance are incorporated into channel design in order to allow for acceptable levels of safety and minimize the probability for incurrence of vessel or hull grounding.
