Ship Stability & Safety Analysis Including Hydrodynamics & Aerodynamics Effects
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Numerical investigations carried out on ship intact and damage stability using FEA and CFD. Many intact stability cases dealing with parametric rolling are effectively investigated with numerical simulations. combination of sophisticated FEA and CFD software is used by Enteknograte’s engineering team in many numerical investigations to effectively model both ship rolling and also internal flooding on decks:
- Intact stability
- Parametric rolling computations
- Damage stability
- Survival times
- Flooding simulations
- Accident simulation for the stability analysis of ship
Various factors can form operational limits for the use of a vessel and ship oprability. Often these are excessive ship motions or accelerations, which can make human work in certain situations impossible or unsafe. On special vessels such limits can be connected to operation of certain equipment. On an offshore vessel or a research ship a limiting factor can be e.g. water motion in a moon pool. Many of these factors or parameter values can be directly measured in model tests, or the number of occurrences of an undesired event over time (shipping of green water, slamming) can be counted in a model.
Operability limits can also be of more functional nature, e.g. holding a vessel steady against an offshore windmill foundation, or launching and recovering a dinghy safely onboard in seaway. Many issues related to dynamic stability of the vessel in waves, e.g. steerability of high speed marine vehicle in waves or the dynamic stability of a vessel against excessive heeling in extreme sea states:
- ship motions and accelerations Simulation
- shipping of green water analysis
- slamming impacts simulation
- sloshing simulation
- steerability in waves analysis
- DP -capability simulation

Transient Resistance, Propulsion, Sea-Keeping and Maneuvering Simulation
Using cutting edge solver technology, Enteknograte’s customers have been able to tackle some of the most demanding problems that the marine industry has to offer, allowing us to predict how designs will react in operation, before budget is committed to the construction of expensive prototypes. Enteknograte’s Engineering team provides analyses ranging from: ship keeping, slamming and sloshing; wave and wind loading on offshore and underwater structures; oil and pollutant dispersions to cavitation control and propulsion system optimization.
CFD analysis can optimize ship hull design, sail shape and propeller blades. Analysis predicts water free surface around the ship hull which helps to accomplish optimal hull shape with low hydrodynamic drag. CFD provides information to optimize sail shape and location for efficient and stable ship. CFD analysis can optimize propeller blade design for energy efficient ship and avoid cavitation on the blades. Enteknograte’s Engineering team provides analyses ranging from: ship keeping, slamming and sloshing, wave and wind loading on offshore and underwater structures, oil and pollutant dispersions and cavitation control to propulsion system optimization.
