Our firm provides a range of naval architecture and marine engineering and analysis services in support of vessel design, construction, operation, maintenance and conversion.

HEC also applies its engineering expertise to research related to new and developing regulations with an emphasis on their impact on existing ships and new designs.

The following is a small sampling of recent projects showing the breadth of HEC's expertise:

General Engineering Analysis

  • Prepared Instruction video on Parametric Rolling for P&I Club (Training Video Brochure)
  • Conducted ultimate strength analysis of tankers for Owner
  • Evaluated rudder horn cracks on new 4250 TEU containership
  • Provided marine vessel design consulting for terminal air emission remediation
  • Evaluated passenger ship structural survivability and ultimate strength
  • Helped Owner evaluate tankage arrangement for voyage loading flexiblity on new cruise ship
  • Prepared ballast water management plans for tankers and cruise ships
  • Determined fatigue loads from ship motions and accelerations and from FEA for proprietary LNG tank design
  • Engineering feasibility studies for several proprietary LNG containment concepts and full design development of ships to transport pressurized LNG
  • Preliminary design of "Prism" membrane-tank LNG carrier to minimize sloshing loads
  • Preliminary design of offshore steel Gravity Base Structure for LNG offloading, storage and regasification terminal
  • Concept design of modifications to Large LNG carrier to offload at submerged turret buoy
  • Provided top-level review and recommendations for design loads for flexible break bulk cargo securing system, including factor of safety and ultimate strength criteria
  • Provided on-site engineering support for float-out of deep draft vessel from graving dock to ensure critical clearances were maintained accounting for changing tides, air-bag floatation failure, structural block removal and hull girder deflections
  • Preliminary design of hull structure and Finite Element Analysis of midship section for multipurpose naval supply vessel

Regulatory Support and Research

  • Developed integrated methodology calibrated against historical data for predicting the risk of accidental oil outflow from Aframax tankers as part of the European Union POP&C project (through European subsidiary)
  • Studied LNG carrier intake and discharge at terminal
  • Developed a quantitative methodology for evaluating structural designs in the case of accidental damage (D4S and PRADS 2007 papers)
  • Prepared damage stability calculations for USCG in support of IMO Rule Harmonization (HARDER Study)
  • Performed bunker oil outflow study for USCG in support of IMO regulatory evaluation
  • Organized an industry forum on marine vessel emission regulations and their potential impact on Owners/Operators
  • Developed software for calculation of oil outflow per new IMO regulations
  • Evaluated Marpol 78 outflow regulations for Intertanko
  • Prepared a study and regulatory analysis of the economic impacts of proposed ballast water standards for USCG
