Marine Fenders

Choosing the right PIANC-compliant marine fender system

Choosing the right PIANC-compliant fender system

An essential consideration of a Quick Release Hook system is selecting a complementary fender system that effectively cushions and protects against impacts between a ship and other vessels, berth, jetties, and piers.

To meet the wide-ranging safety requirements of fender systems, Glen supplies all major classifications of fender types, including rubber fenders, foam fenders, pneumatic fenders, and tug fenders.

Glen’s fender system solutions meet all the quality and reliability standards recommended by the World Association for Waterborne Transport Infrastructure, or PIANC – the leading global organization for guidance and technical advice for sustainable waterborne infrastructure to ports, marinas, and waterways.

Our fender systems are designed to meet a wide range of conditions and stresses, and manufactured from the highest quality materials to ensure reliable, resilient performance.

Highly experienced in recommending fender systems, Glen’s expert design team will recommend the most appropriate system that matches our customers’ precise requirements. To enable this, a number of technical considerations determine the suitable fender system for each vessel:

  • The effective berthing energy of the vessel
  • Reaction force allowed by the berthing structure
  • Maximum hull pressure the vessel can withstand
  • The position and area that the fender system protects
  • Environmental and weathering factors (including wind, sea current and waves)

To select an appropriate fender system, Glen requests operators supply essential vessel and berthing data to aid our recommendations.

Required vessel data

  • 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
 
Required berthing data
  • Berth type: wharf, jetty, pier, etc.
  • Construction type: pile type, gravity type
  • Elevation: top deck (platform) level, high water level and low water level

For existing quay structures, the additional information is required:

  • Space for fender installation at the relative elevation above sea level
  • Allowable horizontal impact force acting on the structure

 

Environmental Data required

  • Wind: direction and speed
  • Current: direction and speed
  • Wave: height, period and direction

 

Rubber Performance Properties

GLEN’s rubber fenders are manufactured from the highest quality natural rubber and other styrene-butadiene SBR based compounds, to satisfy various performance requirements. Other special rubber is also available upon customers’ individual requirements.
