Summary

SUMMARY

‐The increase in vessel sizes and new developments e.g. specialcoatings, leads to new requirements on Fender Solutions.

‐ Designs have to incorporate all conditions at site and available

Norms.

‐ Vital data (e.g. velocity) and requirements (e.g. stand‐off) have

to be collected and evaluated thoroughly.

‐The demand for Customised Fender Solutions is increasing andchallenges especially the final client when comparing fender

designs.

TREND: STANDARDIZATION => CUSTOMIZATION
