VIKING PS4002 Immersion Suit

Common issues

• Zipper corrosion or seizure from salt exposure and infrequent use
• Seam delamination or leakage developing with age
• Neoprene/rubber material stiffening or cracking, especially with UV or heat exposure in storage
• Retro-reflective tape degrading or detaching
• Storage container damaged by UV, moisture or physical impact
• Suit sizing not matching the assigned crew member, affecting donning time and thermal protection

Inspection checklist

• Check the suit is within its certified service life and, where applicable, its periodic test/service date
• Run the zipper fully open and closed to confirm smooth operation
• Visually inspect all seams for damage or separation
• Check face seal, thumb loops and any inflatable head support (if fitted) are intact
• Confirm retro-reflective tape is present and adhered
• Check the storage bag/container and its stowage location marking
• Confirm the crew list assignment matches the suit inventory, including required spares
• Review donning drill records for this suit/crew member

Service intervals

Typical wear limits

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

• Not user-serviceable beyond basic inspection - zipper and seam repairs must go through a manufacturer-approved service station; the items below are inventory items, not repair parts
• Spare suits held to match the full crew complement plus the required margin, in the correct size range
• Replacement storage bag/container where the original is damaged
• Attached whistle and light replacement units matching the suit's SOLAS-required accessories
• Retro-reflective tape (fitted by an approved service station only, not a field repair)
• Talcum/donning aid as specified by the manufacturer to ease donning

Safety

• SOLAS requires the suit to be donned within 2 minutes without assistance - crew need practice to meet this reliably
• A wrongly sized suit compromises both donning time and thermal protection in the water
• A damaged or aged suit can fail to keep water out, leading to hypothermia in an actual emergency
• Suits stowed in inaccessible or poorly marked locations delay emergency use

Class survey

Immersion suits are an LSA Code / SOLAS III item. Class/flag state check the suit's Wheelmark or equivalent SOLAS approval, that the number carried matches the crew complement plus required spares, and that any manufacturer-mandated periodic servicing has been carried out and recorded.
