structural integrity

Structural integrity

Optimum structural design is a must for a ship. It enables to operate a safer, longer lasting, and more environmentally friendly vessel. This design includes strength, fatigue and dynamic analysis, and can focus on key structure elements such as shaft line alignment. All studies are performed with state of the art Finite Element Analysis models, and can also be compared by onboard measurements performed by our team.

As modern vessels are built ever-larger and used each time longer, they are expected to carry increasingly heavy loads and subject to higher fatigue loads. It poses a challenge to the ship’s structural integrity. Issues relating to fatigue life, hull-shaft misalignment, and poor hull girder strength can significantly impact a vessel’s structural integrity, and consequently, its long-term performance. Ship owners and operators need structurally sound vessels to ensure crew and cargo safety, and avoid costly damage from challenging sea conditions.

  • Our  technical expertise in vessel design assessment via advanced finite element modeling (FEM) software helps optimize your vessel structure.  
  • Our customized, client-oriented solutions enable you to achieve specific objectives, such as minimizing unplanned vessel downtime.    
  • Our calculations and assessments using advanced software help you achieve optimum shaft alignment and avoid high vibration levels
     

Our offer

Strength analysis


Bureau Veritas Solutions Marine & Offshore verifies your vessel’s strength, calculating the maximum static load it can withstand, according to the relevant standard. Our services include static calculations, buckling and ultimate strength assessment, structural analysis of composite and bonded structures, and thermal and thermo mechanical analyses.

Fatigue and life extension


Bureau Veritas Solutions Marine & Offshore evaluates your vessel’s design to ensure its fatigue life exceeds its operational life. We make recommendations on structural modifications based on fatigue analyses and life extension studies that assess fatigue-related damage.  

Dynamic analysis


We perform dynamic calculations to evaluate your vessel’s structural response to natural wave frequencies and vibration modes. Our services include blast and seismic analyses, and collision and drop objects assessment.

Shaft alignment


Bureau Veritas Solutions Marine & Offshore assesses the compatibility of your vessel’s hull and shaft alignment to optimize loading and discharge conditions. We perform elastic alignment calculations that take into account flexibility, steelwork deformations, propeller forces, and oil film characteristics.

Complex non-linear analysis


We evaluate your vessel’s ability to support static loads in waves to improve structural integrity in challenging conditions. We perform complex non-linear analyses involving geometric and material non-linearities, to evaluate weaknesses in complex mechanical systems.
