ISO 19357:2016 PDF

Overview

ISO 19357:2016 - Ships and marine technology - Marine cranes - Design requirements for low temperature operation - defines design, construction, safety, performance, acceptance testing and operational requirements for marine cranes intended to operate in low-temperature environments. The standard targets cranes exposed to cold climates (including polar service) and ensures mechanical, hydraulic, electrical and material systems remain reliable and safe at specified low temperatures.

Scope - what it covers

ISO 19357:2016 applies to:

• Deck cranes on ships for cargo/container handling in harbour or sheltered waters
• Floating cranes / grab cranes mounted on barges or pontoons in harbour/sheltered waters
• Engine-room and provision cranes on ships and floating docks for handling equipment and stores

It is not applicable to cranes with minimum ambient operating temperatures no lower than −20 °C, nor to ambient temperatures above +45 °C, nor to a list of specific lifting appliances and shore-based or hand-powered cranes.

Key topics and technical requirements

• Design temperature / Polar Service Temperature (PST): Design service temperature (DST) equals PST and must be set by shipowner/designer at least 10 °C below the lowest Mean Daily Low Temperature (MDLT) for the intended area/season.
• Loads: Requirements for structural, snow and ice loads (snow and ice accumulation considered in storage condition). The document specifies calculation bases for snow and ice loads to ensure structural integrity.
• Material selection: Guidance on rolled steels, forgings, castings, welding consumables, and impact properties suitable for low-temperature service. Material grades and impact requirements are selected to avoid brittle fracture at low temperatures.
• Power, hydraulic and lubrication systems: Reliability of hydraulic oil, gear oils and greases at low temperatures; selection of low-freezing fluids and sealing materials.
• Structure and safety systems: Structural design, insulation/heating of critical components, cabin protection, moisture protection, surface protection, platforms and access for safe operation in cold climates.
• Rope, sheaves and removable parts: Materials, bearings and lubrication suitable for low-temperature operation.
• Inspection and acceptance: Functional and performance tests, visual and surface-protective inspections specific to cold environment readiness.

Applications - who uses ISO 19357:2016

• Shipowners and designers planning vessels for polar or cold-region service
• Marine crane manufacturers engineering cranes for low-temperature operation
• Shipyards and classification societies for compliance checks and certification
• Maintenance and inspection teams implementing tests, acceptance procedures and cold-weather inspections
