04E.31.01

Regular maintenance and rigorous compliance are crucial to ensuring the reliability and safety of maritime evacuation systems. Global Davit GmbH’s model 04E.31.01, certified for medium capacity crew evacuation under SOLAS, is designed with these principles in mind. The davit system, identified by model number 8682610 HH, meets IMO standards and has been approved by DNV, ensuring it adheres to the highest safety protocols. To maintain its integrity, the On-Load-Release-Gear (OLRG) requires an annual functional test at 1.1 times the safe working load (SWL), followed by a check for proper locking mechanisms, dry paint or corrosion in the lock, and wear on threads or shafts. A more comprehensive five-year dynamic test is also mandated to ensure ongoing safety. The wire ropes should be inspected regularly for kinks, corrosion, and broken strands exceeding 10% over an 8d length, necessitating replacement if found. These inspections must include turning the falls for thorough examination and adhering to the manufacturer’s recommended renewal intervals. The braking system, comprising both centrifugal and holding brakes, needs regular checks for wear on brake linings and proper lowering speed, which should not exceed approximately 36 meters per minute. The remote release function must also be verified, ensuring that the brake is not inadvertently locked due to neglect. Corrosion of the davit structure, particularly in zinc-coated areas and stainless steel fastenings, should be monitored for signs of pitting or discoloration. Non-destructive testing (NDT) can help detect cracks in critical load-bearing components, as seen in incidents like the RRS Sir David Attenborough in 2021. Maintenance compliance is essential, with a focus on consistent annual and five-year inspections documented in the logbook, following manufacturer instructions and using only authorized personnel. Weekly engine tests for at least five minutes, annual servicing of release hooks by approved providers, and GRP hull inspections during docking further contribute to the system’s reliability. Spare parts are available through Global Davit GmbH or authorized distribution partners, with a lead time of 2-6 weeks.
