Описание (английский):

This document specifies requirements for the design, construction, safety, performance and acceptance testing of dual traction/stowage winches for oceanographic research (hereafter referred as to “dual traction/stowage winches”), with hydraulic and electric drive. Dual traction/stowage winches are mainly used for fixed-point and towing marine survey, involving marine geological sampling, seawater water body parameter measurement and marine biological survey.

Overview - ISO 5540:2023 - Dual traction/stowage winches for oceanographic research

ISO 5540:2023 specifies requirements for the design, construction, safety, performance and acceptance testing of dual traction/stowage winches with hydraulic and electric drives used on sea‑going vessels for oceanographic research. The standard covers winch components and systems used for fixed‑point and towing marine surveys, including marine geological sampling, seawater parameter measurement and marine biological surveys.

Key topics and technical requirements

Scope and terminology: Defines key terms such as safe working load (SWL), nominal speed, dynamic factor and winch orientation types (LVR, RVR, LVL, RVL).

Design & strength:

Structural stress limits under maximum load (allowable stress ≤ 0.45 × material upper yield strength or specified p0.2 yield).
Holding load requirements: holding load ≥ SWL × dynamic factor (minimum 1.5 × SWL when dynamic factor < 1.5).

Drum and spooling:

Drum diameter for steel wire ropes ≥ 16 × rope diameter; maintain ≥ 5 laps remaining rope; flange clearance ≥ 2.5 × rope diameter.
Spooling and guide sheave ratios aligned with rope/manufacturer requirements; spooling device driven independently or via drum transmission.

Traction & buffer devices:

Multi‑groove traction drums, anti‑jump devices, optional buffer devices to attenuate sudden tension changes.

Drive, brakes and control:

Electric systems conform to IEC 60092; minimum deck enclosure protection IP56 (IEC 60529).
Hydraulic systems conform to ISO 4413.
Continuous operation under SWL at nominal speed (generally ≥ 30 min), overload protection, normally‑closed brakes able to withstand holding load without damage.
Stepless speed control, alarm functions (overload, overspeed, low rope margin, hydraulic alarms), optional Active Heave Compensation (AHC).

Instrumentation & tests:

Required subsidiary devices: tension, speed and rope length measuring devices.
Acceptance tests include function test, static and dynamic load tests, AHC test and inspection documentation.

Practical applications and users

ISO 5540:2023 is used by:

Marine equipment manufacturers and winch designers (winch design and acceptance criteria)

Shipbuilders and naval architects (deck machinery integration, structural verification)

Oceanographic institutions and vessel operators (specifying and procuring survey winches)

Classification societies and surveyors (type approval and inspection)

Maintenance engineers and safety officers (operation, testing and alarms)

This standard helps ensure reliable, safe and interoperable winch systems for marine survey operations, improving data collection continuity and crew safety in variable sea states.
