Fender Type & Pianc Approval
PIANC type approval can prove the products have a reliable quality and the reasonable design requirements.
Following conditions need to be determined in order to choose a suitable fender system:
- Effective berthing energy of vessel
- Reaction force allowed by the berthing structure
- Maximum hull pressure the vessel can withstand
- Position and area for the fender system to protect
- Natural environment (including wind, current and wave, etc.)
Required information
- Vessel type: general cargo vessel, oil tank, container ship, bulk cargo carrier, ferry, cruise and workboat, etc.
- Weight: gross tonnage, dead weight tonnage, displacement, etc.
- Length of vessel
- Width of vessel
- Depth of vessel
- Laden draft
- Free board
Berthing structure
- Type: wharf, jetty, pier, etc.
- Construction: pile type, gravity type
- Elevation: top deck ( plat form ) level, high water level and low water level For existing quay structure, following additional information is also needed:
- Space for fender installation at the relative elevation above sea level
- Allowable horizontal impact force acting on the structure
Natural conditions
- Wind: direction and speed
- Current: direction and speed
- Wave: height, period and direction
