Davit System (Lifeboat/Raft) · Lifesaving Appliances (LSA)
Designed to ensure safe crew evacuation and enhanced safety at sea, the Palfinger Marine Safety AS NPDS 3500H FR is engineered with a focus on reliable operation. This lifeboat operates based on SOLAS (International Convention for the Safety of Life at Sea) standards, ensuring it can carry the required persons capacity as per certification. For crew evacuation and safety missions, this vessel features a diesel engine that must be tested regularly to prevent start-up failures. Common issues include corrosion or blockage in the release hook mechanism, which is critical for safety; failure of the GFK (Glass Fiber Reinforced Plastic) hull under prolonged water contact leading to osmotic blister formation; malfunctioning of the air supply system's ventilation valve; degradation of safety harnesses due to UV and weather exposure; and engine start-up issues arising from infrequent testing. Regular maintenance, including weekly engine test runs for at least five minutes and annual servicing of the release hook by an approved service provider, is essential. Additionally, a GRP hull inspection should be conducted during docking, with a thorough examination every five years to maintain the vessel’s integrity and safety standards.
What our service work and the manufacturer documentation say about keeping this model running.
Weekly engine test run (min. 5 min). Release hook servicing annually by an approved service provider (SOLAS MSC.402(96)). GRP hull inspection at docking. Five-year thorough examination.
| Weekly operational test | per SOLAS - operate davit through its range, lower boat if practicable |
|---|---|
| Monthly launching appliance inspection | visual and functional per LSA Code |
| Annual thorough examination | by a competent person, per SOLAS III/20 and the LSA Code |
| Wire fall renewal | per the maker's schedule or when rejection criteria are reached, typically within 5 years or earlier on condition |
| On-load release gear overhaul and load test | every 5 years, per SOLAS III/20.11 |
| Wire fall | reject per the LSA Code wire rope rejection criteria - broken wire count, diameter reduction, or corrosion, not a single number |
|---|---|
| Brake lining | inspect per the maker's manual for glazing and contamination as much as thickness |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Davit and on-load release gear fall under SOLAS III/20 and the LSA Code testing regime - class/flag requires annual thorough examination and 5-yearly overhaul with load test records; on-load release gear overhaul records are specifically checked at survey.
Estimated lifetime: Davit structure is typically designed for the ship's service life with periodic overhaul; wire falls and on-load release gear are life-limited/condition-limited components renewed on the schedule above rather than by running hours.
