ISO 7613:2025 PDF — Ships and marine technology — Hopper dredger — Suction tube position… — GOST Standards

System scope and integration
- Applicable to installed STPM components and systems; can operate stand‑alone or be integrated into a Hopper Dredger Supervisory and Control System (HD‑SCS) and SCADA.
- Includes a tidal-data interface and adherence to human‑machine interface (HMI) graphics per ISO 20662.
Core components
- Suction tube posture measurement sensors
- Suction tube inlet draught and inlet sensors
- Gantry and winch posture/position sensors
- Swell compensator stroke and pressure sensors
- Signal collecting & processing unit; display/output unit
- Suction tube winch controller (STWC) for coordinated movement/control
Functional requirements
- Tide input (tide table, manual input, or tide gauge)
- Parameter presets (tube length, draghead/gimbal sizes, sensor parameters)
- Operation controls: hoisting/lowering, gantry/winch control, visor angle, swell compensator regulation
- Visualization: continuous SCADA display of 2D/3D views, target/current depths, distances, visor angle, winch speed, system statuses and limits
- Alarms and recording: defined alarm conditions for unsafe depths, distances and angles; alarm display and recording on SCADA
- Calibration and diagnostics: vertical/horizontal calibration routines, manual depth calibration and diagnostic outputs for gantries, winches, swell compensator and active draghead
Performance
- Accuracy: maximum permissible error ±0.15 m for draghead depths from 0–30 m; a depth‑dependent error is specified for depths >30 m (see ISO 7613 for exact formula).
- Planar position error: ±0.25 m in ship coordinates.
- Data recording: interval ≤2 s, storage for at least 24 h continuous recording, data replay available.
Enclosure & power
- Enclosure IP requirements per IEC 60529: IP68 for submersible items, IP56 for deck outdoor equipment, IP20 for console devices.
- Power: main and standby feeds; servers/workstations/switches on UPS with fail‑safe operation and at least 30 minutes autonomy.
Verification
- Functional and performance test methods provided (Annex A and B, informative) plus enclosure tests per IEC 60529 methods.
