Inflatable Life Raft (SOLAS-A) · Life Rafts
Designed to ensure rapid deployment and reliable performance in emergency situations, the RFD Surviva TO Mk IV (also known as Survitec RFD, Survitec Zodiac and Survitec) (Surviva Mk4 Family TO rafts (6-25 TO)) is a medium-sized crew evacuation liferaft certified by SOLAS. This model is engineered to provide critical safety in maritime operations, with a capacity that meets the rigorous standards set by the UK Maritime and Coastguard Agency (MCA). However, common failures can compromise its effectiveness, such as an expired hydrostatic release unit (HRU), which is a critical safety issue, or pressure loss in the CO2 bottle due to corrosion or aging. Additionally, UV exposure on deck can cause material degradation, while fangleine corrosion and blockage are also frequent issues. Ensuring that survival equipment like flares, water, and provisions are up-to-date is equally important for maintaining the raft's readiness. To keep the RFD Surviva TO Mk IV (also known as Survitec RFD, Survitec Zodiac and Survitec) (Surviva Mk4 Family TO rafts (6-25 TO)) in optimal condition, annual servicing at an approved service station is mandatory. This includes replacing the HRU at the manufacturer's recommended interval, typically every two years, and recertifying or replacing the liferaft every five years. Servicing should only be conducted by authorized personnel to ensure compliance with SOLAS regulations (SOLAS/MSC.1/Circ.1328). Keeping a spare HRU on board is also crucial for immediate deployment in an emergency.
