Abstract

Overview

ISO 7613:2025 - Ships and marine technology - Hopper dredger - Suction tube position monitor (STPM) standardizes the design, components, interfaces, technical requirements and test methods for suction tube position monitors installed on hopper dredgers. It covers the installed system elements, functional and performance requirements, enclosure and power-supply criteria, and verification/test procedures (function, performance and enclosure tests).

Key topics and technical requirements

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.

Applications - who uses this standard
