Our Offering

Our will is to keep environment friendly vessels high with a charming design. An excellent team of Naval architects and designers managed by experts in marine & offshore industry is the back bone of our firm.

Our services in design are

1. Basic Design – From concept design to class approval.

2. Production Design – From Nesting to cutting plans & routing.

3. Naval Architecture calculations – All Design calculations in marine & offshore industry.

Production Design

Advanced outfitting in blocks is the most favored method of construction adopted by all leading shipyards. This is a major factor contributing to reducing the time period of construction. A critical element enabling this method is the production design support. This includes 3-D modelling of all the structure and outfitting including piping, outfitting, HVAC and cable tray. Navgathi’s team is capable of supporting shipyard for construction in the marine and offshore industry.

  • Structural
  • Piping
  • Outfitting
  • HVAC & Cable Tray

Software Used

For all major projects, we use FORAN V70 (from SENER) to perform hull form design and all naval architecture calculations. For smaller projects we use Delftship Pro for such design and calculations.

The structural modeling and analysis is performed in Solidworks.

For CFD we use OpenFOAM. In case of slender hulls we perform powering calculations in Michlet.
