Gangway selection is an envelope study. Measure the fixed platform, gap, vehicle landing range, horizontal and vertical motion, parked position, obstructions, use frequency, and worker task before discussing a particular configuration.
Questions this guide organizes
- Reach envelope
- What are the minimum and maximum horizontal gap and landing elevation across every intended vehicle and position?
- Landing condition
- Where can the gangway land, how large and consistent is that surface, and what rails, domes, hatches, equipment, or curvature affect it?
- Motion and parking
- Where does the gangway move and rest, what loading equipment shares the space, and how is readiness confirmed before access?
- Use context
- How often is it used, by whom, for what task, with what tools, exposure, actuation expectation, and maintenance access?
When to use this guide
- New platform projects that need the gangway envelope defined before steel, loading equipment, and enclosure geometry are fixed.
- Retrofits where a current gangway does not reach, park, land, or operate consistently across the vehicle range.
Related decisions to coordinate
- Platform edge and support, guardrail transition, stair and egress path, gangway actuation or assist, parked position, and maintenance.
- Vehicle profile and landing surface, parking or spotting tolerance, departure prevention, communication, and owner work procedure.
- Cage or enclosure, loading arm, piping, hose, hatch, overhead limits, lighting, weather, utilities, and nearby structures.
What this guide does not decide
- A nominal height difference or product photo does not establish the required motion envelope, landing fit, or structural interface.
- The selection cannot solve an uncontrolled vehicle position, unsuitable landing area, obstructed travel path, or undefined fall-protection basis.
- Final geometry, loads, operating method, access, guarding, electrical needs, and safety criteria require project-specific validation.
Information to gather
- Dimensioned platform-edge plan and elevation with gap, edge construction, support, guardrail, and parked space.
- All vehicle profiles with landing-surface details, minimum and maximum elevations, and parking or spotting tolerance.
- Motion and obstruction sketch including cage, loading equipment, hatch, dome, piping, structure, and overhead clearance.
- Task, worker route, tools, frequency, desired operation, exposure, inspection, and maintenance expectations.
- Owner access and fall-protection basis and the responsible structural, mechanical, operations, and safety contacts.
