Ship Specific Studies

When it comes to solving difficult problems for leading companies with in the marine industry C. R. Cushing & Co. has been at the fore front providing creative and cost effective solutions for over the past forty years.

These are a few of the services we have had a pleasure in providing our clients:

  • Developed alternative hull forms for comparative evaluation of resistance, propulsion, seakeeping, ship motions, and maneuvering characteristics for numerous ship design projects.
  • Carried out seakeeping studies on a large, oceangoing catamaran.
  • Supervised parametric tests on optimum bulbous bow forms for a variety of ships.
  • Developed different stern form designs, including conventional waterline flow and buttock flow (Pram) type sterns.
  • Carried out systematic studies and model tests to develop optimum trim.
  • Carried out designs, investigations and model tests on a series of broad beamed, large containerships with pram-type sterns.
  • Designed vessels for various grades of ice class.
  • Prepared model test agenda for each phase of hull form design for many projects.
  • Evaluated model test facilities for conduct of model testing on several occasions based upon the model test agenda contemplated.
  • Evaluated model test quotations and carried out selection of model test facility on many different projects.
  • Worked with major model test facilities of the world, including MARIN (Wageningen), HSVA (Hamburg), SSPA (Gothenburg), IHI (Yokohama), MHI (Nagasaki), the University of Michigan (Ann Arbor), and Davidson Laboratory (Hoboken).
  • Evaluated model test results and prepared corresponding performance predictions.
  • Carried out study of different thruster arrangements for evaluation of necessary ship maneuvering capability.
  • Carried out numerous evaluations of maneuvering capability based on principal particulars and rudder type and area.
  • Evaluated and selected thruster type and size based on vessel mission requirements and life cycle cost analysis.
  • Performed calculations to reconstruct the tracks of vessels in shoal waters.
  • Developed data on a number of vessels, including tankers and passenger ships on squat.
  • Analyzed vessel performance, including power, speed, and vessel motions in varying ocean weather systems.
  • Performed a systematic series of designs of breakwaters and bow forms for low freeboard vessels operating in waves.
  • Analyzed the ship motions of containerships and compared with computer program predictions.
  • Carried out wave refraction and diffraction calculations to assess wave height and period in marina.
  • Safety audits on large cruise vessels
