Designing bilge keels

Project introduction

Our task in the project was to design bilge keels to reduce the rolling motion of the vessel of three different sea-going floating cranes operating in R3 zones.

Characteristics

  • Type: Floating crane
  • Operating zone: Sea, R3 zone

Main dimensions

  • Length: 36,3 m
  • Width: 18,5 m
  • Displacement: 1101 t

Construction design

Welded steel structure

Performed main tasks

  • Creation of three-dimensional models of the hulls
  • Sizing of the bilge keels, calculation and optimization of damping effects
  • Strength calculations using finite element method
  • Construction plans
