Ship design

SALTECH offers complete ship design services from feasibility studies, vessel concepts and naval architectural calculations to basic and detailed design. Our services combine technical expertise, long-time experience and flexibility to deliver progressive and innovative ship designs ready for the future.

Naval Architectural calculations

  • Ship geometry calculations
  • Structural hull design and strength calculations
  • Weight and centre of gravity calculations
  • Intact stability
  • Subdivision and damage stability
  • Resistance, speed and power calculations
  • Seakeeping

Conceptual design

The concept design phase enables fast product development and a rapid procedure to make strategic and economic decisions at an early stage. The conceptual design could be utilized to receive price indications from shipyards. Conceptual design includes (but is not limited to):

  • Main dimensions in comparison with ship statistics
  • Outline general arrangement
  • 3D visualization
  • Outline specification incl. Makers list
  • Initial hull form
  • Weight estimation and initial stability calculation
  • Speed-power prediction
  • Electrical load estimation
  • Selection of main components
  • Cost estimation
  • Data sheet

Contract design

The contract design phase takes the developed even further with purpose to receive binding quotation from shipyards. The contract design includes detailed solutions for arrangement, ship systems and naval architectural calculations to ensure all aspects of the project. Contract design includes (but is not limited to):

  • Conceptual design
  • Hull form selection and lines plan
  • Naval architectural calculations
  • Midship, fore and aft section
  • Freeboard & Tonnage Calculations
  • Engine Room Arrangement
  • Electrical Load Balance & Principle Single Line Diagram
  • Ship system design (system diagrams will be included)
  • Detailed general arrangement
  • Contract specification incl. Makers list
  • Cost estimate and evaluation

Basic design

Basic design package includes necessary documentation for approval by involved authorities such as classification authorities and flag states. The basic design ensures that safety, functionality, and equipment level are in compliance with applicable rules and regulations. Basic design includes (but is not limited to):

Technical Documentation & Plan Approvals

  • – General Design
  • – Hull Structure
  • – Outfitting & Equipment
  • – Accommodation
  • – HVAC & Piping Systems
  • – Propulsion & Machinery
  • – Electric & Automation
