MARSHALING PORT SPECIFICATION • 200 KPA QUAYSIDE BEARING • 2,500T RING CRANE GAUGE

Offshore Wind Marshaling Port Quayside Bearing Audit

Engineering audit checklist for deepwater marshaling terminals: reinforced concrete apron load ratings, 2,500T ring crane pad compaction, RoRo loadout threshold integrity, and wet storage basin draft depth.

Port Infrastructure Readiness Verification

Complete all 15 audit gates prior to docking semi-submersible transport barges or commencing turbine assembly.

AUDIT COMPLIANCE SCORE 0% (0 / 15 Gates)

Phase 1: Reinforced Quay Apron & Soil Bearing Geotechnics

Uniform Quayside Deck Bearing (≥ 150–200 kPa) Heavy apron reinforced slab verified for 15–20 tons/m² continuous surcharge load across component laydown yards.

Combi-Wall Sheet Pile & Tie-Back Anchor NDT Ultrasonic thickness testing (UT) and diver sonar inspection confirm zero loss of steel pile wall section beneath waterline.

CPT Cone Penetration Foundation Tests Cone Penetration Testing (CPT) confirms backfilled quay fill achieves 95% relative density with zero liquefaction hazard.

Phase 2: 2,500-Ton Ring Crane Pad & Outrigger Shoring

Ring Crane Ground Bearing Pressure (≤ 250 kPa) Steel ring beam distributor mats reduce 2,500T crane operational point loads under 250 kPa allowable limit during 15MW nacelle pick.

Differential Settlement Laser Monitoring (≤ 10mm) Real-time optical leveling sensors detect any angular tilt across the 35m crane ring diameter during slewing cycles.

Superlift Counterweight Tray Clearance 1,000-ton trailing counterweight swing radius swept clear of light towers, utility trenches, and component staging lines.

Phase 3: RoRo Loadout Linkspan & Heavy Mooring Bollards

200-Ton Quick-Release Mooring Bollards Quayside cast-steel bollards proof-tested to 200T safe working load (SWL) to withstand constant-tension barge winches.

Yokohama Pneumatic Fenders (3.3m Diameter) Low-reaction pneumatic rubber fenders installed with aircraft tire netting to protect barge hull plating during tidal rise/fall.

RoRo Ramp Edge Reinforced Lip & Transition Plating Quayside concrete coping edge fitted with 50mm hardened steel wear plate to prevent spalling under 120-axle SPMT crossing.

Phase 4: Wet Storage Harbor Basin & Channel Bathymetry

Multibeam Bathymetric Survey (≥ 14.0m MLW Draft) Full coverage multibeam sonar survey certifies channel depth ≥ 14.0 meters at Mean Low Water with zero high-spot pinnacles.

Wet Storage Temporary Mooring Spreads Harbor basin equipped with 4-point seabed drag embedment anchor moorings to hold assembled 15MW floaters during weather hold.

Tide Gauge & ADCP Current Profiler Continuous acoustic Doppler current profiling (ADCP) verifies port basin cross-currents stay below 1.2 knots for safe float-off.

Phase 5: Airspace & Overhead Bridge Tow-Out Clearance

Overhead Bridge Air Draft (≥ 145m Vertical Clear) Fully assembled 15MW floating wind turbine (tip height ~260m above waterline) verified zero overhead bridge interference to open sea.

Harbor Pilotage & Escort Tug Array Minimum 3x 80T bollard pull azimuth stern drive (ASD) escort tugs contracted and pre-briefed for harbor breakout maneuvers.

Coast Guard Captain of the Port (COTP) Permit USCG / Maritime Authority security zone declared with broadcast notice to mariners (BNM) restricting commercial ship traffic.
