Work Experience

Research project, including concept design of innovative landing craft vessel.  Landing craft featured standard beaching operations.  Innovation included the ability to link multiple landing craft together as a long train of vessels for improved fuel economy.  Work included CFD resistance analysis for vessels in multiple trim conditions.

Inspection and detailed dimensioning of vessel tanks to update vessel stability models for multiple ships in NOAA fleet.  Updated stability information created accurate tank sounding tables.

Detailed design of floating surface collector, which was a unique device for collecting juvenile salmon near hydro-electric dams.  Detailed design included structural design and stability analysis.  Stability analysis included damage stability.

FEA Analysis of critical mooring foundations on floating surface collector.  Analysis incorporated multiple load components and multiple load cases.

Detailed design of floating surface collector, which was a unique device for collecting juvenile salmon near hydro-electric dams.  Detailed design included structural design and stability analysis.

Created a customized spreadsheet for calculating loading conditions on the Alaska Marine Highway System (AMHS) ferries.  Spreadsheet automatically calculated tank loads, vessel hydrostatics, and checked stability limits.  Implemented spreadsheet for every vessel in the AMHS fleet, with customizations for each vessel.

CFD analysis to simulate vessels rising in locks for forensic investigation.  Analysis revealed previously undetected forces that contributed to vessel incident.

High precision CFD analysis to determine the optimum trim conditions for minimum fuel economy on a cargo vessel.  CFD analysis included validation to prove that CFD results accurately resolved the small differences reflected in the analysis.

Rapid CFD study to correct a running trim problem for a yacht client.  Developed CFD free to trim model of vessel, verified accuracy and iterated through numerous potential solutions to correct running trim.  Final solution included addition of an inverted foil to the stern of the vessel to act as a spoiler.  Enter CFD project from start to finish was completed in 72 hours.

Stability analysis of various fishing vessels, under US Coast Guard rules.  This included uninspected vessels, inspected vessels, and alternative compliance vessels.  Analysis included submittal for USCG review and preparation of stability letter for USCG to incorporate into Certificate of Inspection.

Stability analysis of various passenger vessels and ferries.  Included vessels classed under Subchapter H and T of the US Coast Guard.  Analysis included intact and damage stability, submittal to USCG, and preparation of trim and stability booklet.

FEA analysis of articulated tug barge (ATB) connector for fatigue concerns.  Final analysis identified several fatigue points.  Work included design of new ATB foundation to resist further fatigue.

Loadout analysis and transport engineering for approximately 50 voyages to transport cargo modules of gas liquefaction plant.  Transport analysis included ballast plans, stability analysis, seafastening, and cargo securing manuals.

CFD analysis of jackup wind overturning moment. Directly responsible for all CFD analysis and presentation of results. 

This was significant as the first CFD analysis for this type of structure intended for ABS approval, with the goal of eventually replacing the block coefficient method.  

I developed a CFD test program to determine results, prove the validity of the CFD methods, and defended the CFD program with ABS to seek Approval in Principal.  

CFD seakeeping analysis for prediction of motions and stresses on unique vessel concept. Followed by FEA global hull analysis of composite structure. Directly responsible for all CFD and FEA tasks. Also primary project manager for project.

Supported design, HAZID, and HAZOP of innovative well injection barge.  Barge transport well injection chemicals to wellhead site and then submerged to seafloor.  Descent was controlled through tugs and two catengary chain cables.

I developed a CFD motions analysis to confirm safe and controlled descent of the barge.  Test conditions included cross currents and different water depths.  Motions analysis included development of a new catenary cable model, coupled with the CFD computations.

Developed seakeeping and mooring analysis of vessels tied to dock. Analyzed line stresses and vessel motions. Included weather, passing ship analysis, and tidal analysis.

Vessel survey to determine draft mark position. Plus live vessel loading study to determine hydrostatic properties.

Mooring analysis for single point mooring and design of catenary anchor cables.

Seakeeping analysis to determine XMAS tree deployment limits. Included modeling of active heave compensation. Modeled package transfer through splash zone, water column, and near seabed.

Part of owner’s representative team. Attended model tests. Reviewed seakeeping analysis, CFD analysis, and various naval architecture drawings for class submittal.
