FENDER SYSTEM COMPONENTS

2026-11-03

1 . General This performance - based specification covers the design , supply , testing , and delivery of complete cone fender systems for a closed - structure berth at the Mobile Alabama Cruise Terminal on the U . S . Gulf Coast in Mobile , AL . The fender system unit shall comprise a single cone - type elastomeric fender per unit , a steel frontal frame with UHMW - PE low - friction face pads , chain systems , anchorage , and all accessories required for a complete and operable installation . Products from ShibataFenderTeam ( model SPC900 / G2 . 1 ) or Trelleborg Marine & Infrastructure ( model SCN950 / F1 . 4 ), or approved equals meeting this specification in full , are acceptable . This specification requires the delivery of twenty - four ( 24 ) fender units NO LATER THAN August 21 , 2026 . Delivery shall be made to the Alabama Port of Mobile in Mobile , AL . Specific delivery location and arrangements will be coordinated with the successful bidder . Bidders should presume they will be required to offload systems at destination . 1 . 1 Vessel and Design Basis a . Design vessel ( basis of energy ): Cruise liner ( post - Panamax class ) with displacement ~ 50 , 253 t , Lpp 247 m , beam 35 . 4 m , draft 8 . 2 m . b . Berthing approach : side berthing to a closed structure ; bow impact 25 %; angle of approach 6 °. c . Under - keel clearance : 4 m . Velocity for energy derivation : 0 . 10 m / s ( 100 mm / s ). d . Environmental condition : " Good , sheltered " berthing . Design inputs and method reference : PIANC WG33 ( 2002 ) methodology for berthing energy and fender performance / test procedures . Normal energy EN = 178 . 29 kNm ; adopted factor of safety = 2 . 0 ; abnormal design energy EA = 356 . 58 kNm . 2 . System Performance Requirements Performance values below are for the complete fender unit at constant slow compression ( CV ), corrected for manufacturing tolerance and project factors ( velocity , temperature , and angle ). The supplier shall select and configure either SPC900 / G2 . 1 or SCN950 / F1 . 4 ( or approved equal ) to satisfy all requirements concurrently . 1 . Minimum corrected energy absorption ( E_corr ) ≥ 356 . 6 kNm at 6 ° contact angle and 100 mm / s test basis ( apply : - 10 % on energy for manufacturing tolerance ; include VF / TF / AF as per PIANC ). 2 . Maximum corrected reaction force ( R_corr ) ≤ 629 KN at the same conditions ( apply : + 10 % on reaction for manufacturing tolerance ; include VF / TF / AF ). 3 . Average hull pressure limited to ≤ 200 kN / m2 based on corrected reaction distributed over effective flat panel face area . 4 . Single fender unit per system ( one cone body per panel ). 2 . 1 Performance Factors & Tolerances a . Manufacturing tolerance : - 10 % energy , + 10 % reaction ( applied to catalogue CV values ). b . Velocity factor ( VF ): compute per vendor catalogue / test data for 100 mm / s reference . c . Temperature factor ( TF ): compute for site temperature range ; baseline 23 + 9 ° C ; design minimum 0 ° C . d . Angle factor ( AF ): compute for 6 ° contact . 3 . Elastomeric Fender Body Cone - type rubber fender body with integrally bonded internal steelwork . Rubber compound shall be natural / synthetic blend suitable for marine exposure , ozone and seawater resistant , reinforced with carbon black , and free of defects . Embedded plates and inserts to be fully encapsulated ; only stainless steel ferrules exposed at bolting locations . 3 . 1 Rubber Compound - Minimum Properties Property Standard Tensile strength ( orig .) ISO 37 Elongation at break ( orig .) ISO 37 Requirement ≥ 16 . 0 MPa Original ≥ 350 % Hardness ( orig .) ISO 7619 - 1 ≤ 78 Shore A Compression set ( 22 h ISO 815 - 1 ≤ 30 % @ 70 ° C ) Tear resistance ISO 34 - 1 ≥ 70 kN / m Ozone resistance ISO 1431 - 1 No cracks
