Naval Architecture

Marimecs is well experienced in naval architecture and has executed many interesting projects. From weights calculation to speed-power-range predictions and stability calculations following appropriate regulations of Flag-state authorities.

By defining the main parameters the general dimensions, volume and speed-range of the vessel will be specified. With these initial parameters we can start up and make a first loop developing a lines plan, creating a concept styling combined with a general arrangement and starting with initial calculations.

To assess feasibility of the design a extended functional breakdown should be made and discussed with the owner. Due to our experience in naval architecture and specialized in house developed tools we are able to check and monitor our calculations during the building process. If appropriate tank-testing for resistance and sea-keeping behavior and even wind tunnel testing will be executed to optimize performances. After evaluating the design with the owner we will make additional loops until we meet all the requirements.

Taking care of the complete design process

Weight estimation (Excel and Cad)

  • Special weight report and plotting tools

Hull design

  • Linesplan
  • Resistance and propusion calculations
  • Intact and damage stability booklets
  • Inclining tests
  • CFD analyses
  • Weight calculations
  • Production fairing

Hull shape (Rhino)

  • Styling model at In-exterior
  • Production model

Stability (Maxsurf)

  • Intact stability
  • Damage stability
  • Inclining test

CFD optimizations (Open foam)

  • Hull shape
  • Appendages

Design optimization by model testing

In certain cases we can in cooperation with several instances perform and arrange model testing, after testing Marimecs advises for model and design optimization according the results of the tests.

Several runs are done to verify and optimize the design for earlier selected key figures as for example cruising speed and range. After evaluating the design Marimecs makes additional loops till we can fulfill all the requirements.
