  • Finite Element Analysis (FEA) of Ship Structures
  • Docking and Undocking Calculations
  • Docking Plans
  • Weight Control Reporting
  • Deadweight/Lightship Surveys
  • Stability Tests (Inclining Experiments)
  • As-Built Drawings (Structure, Piping, Electrical)
  • Drawing Redline Markups
  • General Arrangement Drawings
  • Capacity Plans
  • Marine CAD Drafting Services

For seven years, I was the Staff Naval Architect and New Vessel Construction Program Manager at Metal Trades, Inc, leading the design/build team effort for US Navy YON 330 through 338 plus a Ship Waste Oil Offloading Barge (SWOB).  The detailed design of the barges was performed by Bristol Harbor Group.  The prime contractor for the US Navy was Maybank Industries.  Key equipment vendors included:  Caterpillar (Pump Engine), Northern Lights (Generator), NAG Marine (TLI System), Sherwin-Williams (Paint System), Flowserve (Deep Well Cargo Pump), Schaefer (Battery Charging System), W&O (Valves), Pauluhn (Lighting), Nabrico (Hatches and Deck Hardware), Centex Marine (Doors), and Hiller Systems (Fire Suppression).

I played a “hands-on” role in writing the Builder Trial test procedures for all Cargo Pumping Systems, Electrical Systems, Tank Level Indication Systems, Diesel Pump Engines, and Gensets.  I also served as the Test Director during the trials throughout the final delivery stage.  I also personally trained the U.S. Navy Fuel Barge Operators in Norfolk, Virginia and Pearl Harbor, Hawaii on all systems aboard each type of barge built by Metal Trades during my seven years as the Program Manager.

Randy Brown is an exceptional project and program manager. His attention to detail is what makes the difference.  His thoroughness yields vessel designs that are thoughtfully executed, and in the end, it is this detail that is most appreciated by the owner.  He is also passionate about his work, which is a quality that you cannot teach.  This passion, in conjunction with the depth of his technical knowledge and skill, makes working with Randy a true pleasure.

Re-design and Arrangement of Fuel Barge Control Room, Added Window and TLI System, Moved Cargo Pump Skids Outside and Above Deck, Improving Safety and Reliability (Effort led by R. Brown, detailed design drawings by Bristol Harbor Group and Matherne Marine Design):

My involvement in this project was extensive as it included:  The complete cost estimate and proposal/bid preparation, Program Management, Naval Architecture lead, re-designing the barge cargo pumping system, arrangement of the deck, stern, and house, and adding new design features beyond what was in the original contract design.

As a “hands-on” Engineer, I also wrote all of the Builder Trial test procedures and directed the final Builder Trial testing of all cargo pumping and electrical systems on the barge for final ABS and USCG approval.

130′ Floating Barge Dock for National Park Service – Naval Architect for Detailed Design and Structural Finite Element Analysis of Fendering System

Finite Element Analysis of Fendering System using NX Nastran – Vessel Hitting Dock at 4 Knots

As the Director of Business Development and Engineering for Metal Trades, I completed the conceptual design, cost estimate, and bid under a very tight deadline of one day after receiving a short notice phone call from the prime contractor, Inland Construction.  After winning the contract, I completed the detailed design and structural analysis of the 130′ long Floating Barge Dock for the National Park Service using Autocad and FEMAP with NX Nastran.  The Floating Dock is used daily to shuttle tourists to the Statue of Liberty from Gateway National Recreation Area in Sandy Hook, New Jersey.

The fendering system had to meet a design requirement to withstand a large ferry hitting the end of the dock at 4 knots. For this, I performed a Finite Element Analysis (FEA) using FEMAP and  NX NASTRAN.

General Dynamics/Electric Boat:  Lead Naval Architect and Project Engineer for the development, testing, and installation of the first Composite/Syntactic Foam Eyebrow Sonar Baffle.  This eyebrow design was installed on 21 fast attack submarines (Improved Los Angeles Class).  It was a critical element of the ships fulfilling their missions with a full complement of weapons, particularly under polar ice.

In recognition of your applied engineering and program management on the SSN752 Syntactic Eyebrow Task, which you directed from concept, testing, design, and installation in one short year, it is my pleasure to present you this Extraordinary Achievement Award.  Your personnel skills in achieving quick cooperation from many disciplines in and out of Electric Boat, contributed greatly to sending the SSN752 on time, with an additional 11 tons of margin, to meet its mission requirements.”
