BMT Designers & Planners, Inc.4401 Ford Avenue, Suite 1000Alexandria, VA 22302703-920-7070www.dandp.com

Founded more than 60 years ago, BMT Designers & Planners has developed a reputation for our structural engineering capabilities, providing sought-after design and analysis services for both commercial and government clients. We have conducted structural engineering analysis to meet the challanges faced by clients on a wide variety of marine vessels, such as:

• Ocean-Going Ferry: Conducted FEA to determine the adequacy of structure designed for the Alaskan ferry M/V TUSTUMENA, which in-cluded seaway-induced loadings on the structure and Spectral Fatigue Analysis during cyclic loading in waves

• SWATH Vessel: Completed the structural design and producibility re-view of an aluminum SWATH vessel for NOAA

• Polar Icebreaker: Performed extensive FEA analysis of the structure under ice loading for the USCG icebreaker HEALY

• Offshore Rig: Conducted the structural FEA analysis of the oceangoing rig CHEMUL for retrofit with a Liebherr MTC 6000 crane

• USCG Cutter: Performed global course mesh and local fine mesh FEA to evaluate structural fatigue strength of the National Security Cutter

• US Navy Vessel: Conducted DDAM analyses for numerous ship equip-ment suppliers leading to US Navy shock qualification of their installations

• Floating Drydock: Analyzed a modified floating drydock confirming it would accommodate a large vessel longer than the dock using FEA

• Barges: Performed an analysis of structural loads induced by seaway motions for barges carrying sensitive equipment

BMT engineers are capable of designing and analyzing marine structures using first principles, class rules and guides, or advanced finite element analysis. We conduct analyses for:

• Ship global, local and hull girder strength

• Local point loads, such as wheel loads on the decks of RO/RO vessels and ferries or aircraft on flight decks

• Machinery/equipment foundations and deck/bulkhead reinforcement

• New configurations of lifting equipment such as deck mounted A-frames, davits, and crane booms

• Design solutions to structural fatigue, deformation, or cracking problem
