BWE-08-031/181

Häufige Probleme

• On-load release hook interlock/hydrostatic mechanism malfunction - a known industry-wide weak point on freefall lifeboat release gear
• Engine starting failure after prolonged lay-up (fuel or battery condition)
• Cradle/ramp corrosion affecting free release during launch
• Skid/ramp friction surface degradation
• Hull GRP damage or gelcoat cracking from UV and weather exposure
• Seat belt/restraint degradation
• Engine cooling seawater intake or bilge pump blockage

Prüfliste

• Function-test the on-load release gear per the manufacturer's procedure and MSC.1/Circ.1206/Rev.1, without a free-fall launch unless the drill schedule requires it
• Inspect the release hook interlock/hydrostatic mechanism for corrosion and free movement
• Start the engine and check cooling water discharge, exhaust and control functions
• Check battery condition and the charging system
• Inspect the hull for cracks, delamination, and check ramp/skid condition
• Check seating, harnesses and restraint systems
• Verify the SOLAS emergency equipment inventory is complete onboard
• Inspect the davit/cradle release mechanism if the boat is also gravity-launchable

Wartungsintervalle

Typische Intervalle für diese Bauart, keine Herstellerangabe für Ihr Modell. Verbindlich ist das Handbuch des Herstellers.

Typische Verschleißgrenzen

Die Bereiche sind für diese Bauklasse typisch. Maßgeblich sind stets die Herstellerunterlagen zur jeweiligen Seriennummer.

Kritische Ersatzteile

• Release hook interlock/hydrostatic unit components - only genuine parts from the approved release gear manufacturer
• Engine starting battery
• Engine fuel filters
• Engine raw-water pump impeller
• Cradle/skid friction pads

Sicherheit

• On-load release gear has a serious industry safety history (multiple fatal incidents) - follow MSC.1/Circ.1206/Rev.1 maintenance strictly and keep persons out of the boat during release gear testing unless required and risk-assessed
• Free-fall drop hazard - maintain an exclusion zone below the skid during any release gear work
• Confined engine compartment fumes
• GRP hull repair resin/fumes are a health hazard - work in ventilated conditions with proper PPE

Klassenbesichtigung

Subject to SOLAS III/20 annual thorough examination and 5-year dynamic (operational) test. Class specifically reviews on-load release gear maintenance records against MSC.1/Circ.1206/Rev.1, given the sector's safety history with freefall lifeboat release systems.

Geschätzte Lebensdauer: The hull and structure are typically designed for 20-25 years of service; engine and release gear components have the shorter overhaul intervals above and are replaced or overhauled well within that period.
