Overview

EN 13852-2:2004 - "Cranes - Offshore cranes - Part 2: Floating cranes" (CEN) is a European safety standard that specifies safety requirements for floating offshore cranes, including their supporting pedestals and structures. It applies to cranes manufactured after the document’s issue date and covers significant hazards, verification, testing, documentation and in-service procedures. The standard excludes fabrication/assembly changes, lifting accessories (between hook and load), designs for temperatures below −20 °C, operations above 50 °C, and cranes already covered by the Machinery Directive. It also includes requirements for the lifting of persons where national regulations permit.

Key topics and technical requirements

EN 13852-2:2004 organizes safety and technical guidance across design, components, systems and operational verification. Major topics include:

• Structure and mechanisms: in-service/out-of-service loads, failure mode analysis, and load combinations.
• Equipment and components: requirements for wire ropes, wire rope terminations and anchorage, winches, brakes, slewing bearings and fasteners, hydraulic cylinders, motion compensators and shock absorbers.
• Drive systems: electrical, hydraulic and pneumatic system requirements and power considerations.
• Heave compensation and rope-tensioning systems: guidance for dynamic offshore motions and operational control.
• Controls, indicators and limiting devices: operator controls, indicators, limiters, and emergency stop/operation provisions.
• Protection systems: Emergency Load Release System (ELRS), emergency operation modes and emergency stop.
• Health & safety and ergonomics: control stations, cabins, communications, access, guards and noise reduction.
• Lifting of personnel: minimum requirements and special provisions (subject to national regulations).
• Verification and testing: functional tests, installation tests, test acceptance criteria and test loads.
• Information for use: documentation, operation checks, maintenance, inspections and marking.
• Normative and informative annexes: dynamic coefficients, environmental influences (wind, ice, corrosion, lightning), failure mode analysis, material selection, wire rope safety factors, slewing systems and brake requirements.

Applications and who uses this standard

EN 13852-2:2004 is used by:

• Crane manufacturers and OEMs for design and compliance of floating cranes
• Naval architects and marine engineers integrating cranes into vessels and platforms
• Shipyards and contractors during installation, commissioning and testing
• Classification societies and notified bodies for conformity assessments and certification
• Maintenance teams, operators and safety managers for safe operation, inspections and procedures
• Procurement and regulatory authorities specifying safety and performance requirements

Practical applications include design verification, selection of components (wire ropes, slewing bearings, brakes), acceptance testing, on-board procedures for personnel lifts, and lifecycle maintenance planning.

Related standards

• European Machinery Directive (as an exclusion reference)
• Other parts of EN 13852 series and relevant crane and marine standards (see Annex A for selection guidance).
