Ensure reliable ship structures by applying holistic approachesPermanent R&D work combined with feedback from fleet in service ensures advisory services on a high level - independent whether a structure consists of steel, aluminium or composites. Global Structural Strength AnalysisA global strength analysis aims to determine global deformations and stresses in ship structures. Loads can be applied in a realistic way to analyse the structural response accurately, especially in complex structures. GL's holistic approach includes systematic fatigue assessment of highly utilized details as well as a comprehensive buckling strength assessment. Results are used to improve and optimise structural designs. The finite element method is particularly suitable for structural analysis of ship designs. Loads can be applied in a realistic way to analyse mechanical or thermal stresses accurately especially in complex structures.GL offers:
Local Structural Strength AnalysisThe objective of a local strength analysis is the investigation and optimization of structural components with respect to their strength and manufacturing performance. This method can be applied on individual components as well as on structural details, which are part of a global structure. The latter are analysed as a sub-model and subjected to loads resulting from the global analysis.GL offers:
Fatigue AssessmentShip structures are affected by stresses that vary over time. They are mainly caused by seaway, propulsion plant excitation forces and changes in loading conditions. Depending on the structural condition and objective fatigue, assessment is offered by means of nominal stress, structural stress as well as notch stress approach. In special cases a fracture mechanics approach by means of crack propagation calculation and fracture assessment will be utilized. As a special service the spectral analysis method is available. Support and consultancy in fatigue testing can be given, too. GL offers:
Ultimate Strength and Collision AssessmentAvoidance of loss of human life and property as well as environmental pollutions caused by ship casualties is one main issue of GL's policy. The importance of collision resistance and ultimate strength assessment of ship structures rises significantly. Sufficient ultimate strength as well as collision and grounding resistance becomes more and more valuable. GL's offers:
