Corrosion, heavy vehicles, and access control.
Marine environments add heavy vehicles, salt, and shifting logistics. Protect landside gates and high-value areas with crash rated bollards suited to corrosion and UV (361–363, 362 duplex options). Coordinate ducting/trench runs (246, 934), schedule operations around tides and cargo windows, and plan incident response (547). Provide approvals with robust certificates and drawings (431, 717), and maintain coatings for lifecycle value (842, 366). Include one-sentence context that naturally links upward to the parent hubs (this section and the chapter hub). Add SIRA context with a link to SIRA Bollards (UAE) when relevant. Link installation pages only if helpful: What to Expect and Installation Guide.
Important: This is a general guide. For live projects we develop a tailored
Method Statement & Risk Assessment (MS/RA) and align with authority approvals (e.g., SIRA) where in scope.
818.1 Marine exposure
Chlorides and galvanic pairs (363, 364). Coatings and sleeves per 362, 361.
Ports and marinas expose metalwork to chlorides, spray, and UV. Choose materials and finishes from 361 Materials selection and 362 Coatings that resist galvanic corrosion and UV chalking. In harsh marine bands, duplex systems (zinc + topcoat) and 316 stainless components reduce pitting risk.
Where steel cores are required for crash rating, use isolation washers and sealant details to break galvanic pairs (see 364 Galvanic risks). Sleeves (composite or stainless) from bollard sleeves shield cores and simplify future recoating.
Document finish stacks and inspection points in the specification and O&M (link to 733 O&M Manuals and 842 Lifecycle & maintenance).

818.2 Freight & apron vectors
High-mass vehicles and long run-ups (214, 223). HVM bollard ratings must reflect energy (414).
Freight aprons and service roads allow long, straight approaches. Map approach vectors with 214 Perimeter & Approach Paths and vehicle classes via 223 Vehicle Classes. Convert run-up distance to credible impact speed using the VDA method and pick the rating that matches impact energy.
For lanes that must pass legitimate freight, combine vehicle access control with clear setbacks and 325 turning allowances. Use 322 clear-gap rules so arrays stop high-mass goods vehicles without choking apron operations.
818.3 Gatehouses & lanes
ANPR, weighbridges, and interlocks (534, 352). Keep crash rated bollard lanes legible (524).
Gatehouses blend 534 access control/CCTV (e.g., ANPR) with lane hardware. Keep 524 HMI & local controls simple and consistent; show lane status, modes, and overrides clearly.
Where weighbridges are in-line, confirm inductive loop placement (344 Induction Loops) and align interlocks with the 352 Interlock Matrix. Provide an EFO path and fail-state philosophy that avoids trapping blue-light vehicles.
818.4 Utilities & ground
Saturated soils drive foundation choices (423, 332). Drainage and sumps are critical (334, 616).
Quays and reclaimed land often have high groundwater and variable soils. Check 423 groundwater/soil effects and select from 332 foundation types (deep sockets, grade beams, or shallow rails) that accommodate utilities from 246 Ducting & Pathways.
Prevent water ingress into equipment pits with 334 drainage, draw-pits, and 616 sumps. Confirm dewatering plans if tides or perched water will be encountered (see 614 Dewatering).
818.5 Hazardous cargo zones
Define exclusion and fail-safe behavior (355). Evidence in RAMS (722).
For explosive or volatile cargo areas, set exclusion perimeters and 355 fail-safe/secure states that default to safety under power loss. Use Request→Authorize→Execute logic to prevent mode errors.
Capture reasoning, assumptions, and mitigations in the 722 Risk Assessment and MS, including lockdown and emergency egress rules.
818.6 Vessel interface areas
Protect quayside equipment without blocking access (372). Arrays respect turning (325).
Protect cranes, fuel points, and shore-power pedestals as 372 outdoor assets. Keep servicing clearances and 325 turning paths open. Use 326 mixed-type arrays when combining fixed and automatic lanes near berths.
Where vehicle lift risk exists at edges, check capture height and 314 deflection vs permanent set to avoid secondary hazards.
818.7 Corrosion inspections
Regular checks and cathodic strategies (365, 361). Records to 733.
Establish inspection bands (splash, tidal, and atmospheric) and schedule cleaning, rinse SOPs, and 365 design-for-maintenance. Where dissimilar metals remain, consider dielectric isolators and, in severe cases, cathodic strategies coordinated with port systems.
Log all findings and coating readings in the 733 O&M manuals, with photos and serials from 732 asset registers. Use the Maintenance Interval Planner to tune intervals to exposure.
818.8 Lighting & signals
Fog/night conspicuity (353, 357). Avoid glare to operators (316).
In low-visibility ports, pair lane beacons with 353 safety signalling and 357 markings. Balance conspicuity with glare control and the visual language set in 316 Aesthetics. Use night auto-dimming on local indicators to preserve dark adaptation.
818.9 Authority pack
Customs/security documentation (717). Certificates remain centerpiece (431).
Most ports require a clear authority submission. Center it on certified performance from 431 documentation & certificates, then add the tailored 717 Authority submittals set (drawings, calculations, traffic plans, and O&M excerpts). In the UAE, coordinate with SIRA where landside security interfaces with regulated zones.
Include construction coordination: 934 trench details, utilities routes from 246, and commissioning test plans (630 series) so reviewers see an integrated design-through-handover path.

Which crash rating should I target for heavy goods vehicles at a port gate?
Select a rating based on credible impact energy from your Vehicle Dynamics Assessment—combine approach/run-up, vehicle class, and angle. Use VDA, check rating terminology, then confirm equivalency if you’re comparing IWA vs ASTM (414).
