Project Requirements of Marine Fender Systems

The article lists some basic parameters that will be required when choosing and designing Marine Fender Systems for Port. Generally, we divide these specifications into four big parts as following:

• Port
• Project
• Designer
• Contractor

4. Length between perps (LBP) (m)
5. Beam (B) (m)
6. Draft (D) (m)
7. Freeboard (F) (m)
8. Hull pressure (P) (t/m2)

Smallest Vessel / Vessel type

1. Deadweight (t)
