Davit System (Lifeboat/Raft) · Lifesaving Appliances (LSA)
Regular maintenance and adherence to a strict servicing schedule are crucial to ensure the reliable operation of the Duplex 27.0, a crew evacuation system designed to meet SOLAS certification standards. This system, manufactured by Hatecke GmbH, is approved by DNV, ensuring compliance with international maritime regulations. The Duplex 27.0 has a capacity to evacuate persons as certified by SOLAS, making it an essential safety device on any vessel. Common failures that can occur include corrosion or blockage of the release hook mechanism, diesel engine start failure due to insufficient testing, osmotic blistering in the GRP hull from prolonged water contact, and the failure of the air supply system vent. Regular weekly engine tests for a minimum of five minutes and annual servicing of the release hook by an approved service provider are mandatory. Additionally, the GRP hull should be inspected during each docking, and the system undergoes a thorough examination every five years. Spare parts for the Duplex 27.0 can be obtained from Hatecke GmbH or authorized distribution partners, with a typical lead time of 2 to 6 weeks.
