Special 5 Year Extended Service Offer

For Emergency use on Offshore Installations the Challenger Interlock 275N and Challenger Offshore 150N are available in the Extended Service Format.

If stored in the conventional manner ie. hanging in a cabinet - the service interval is every 12 months.

To facilitate extended servicing intervals and to remove the risks of accidental inflation plus prevent individuals from tampering with the lifejacket, ISP developed their Extended Service Packaging System.

Each lifejacket is hermetically sealed in a Mil spec foil laminate bag together with a calculated quantity of moisture absorbent desiccant. Provided the foil laminate bag is not damaged the service interval can be extended for up to 5 years - subject to Flag State acceptance.

Our recommended service regime is to undertake a 20% per year service combined with a 100% inspection of the bags. This ensures the maintenance budget remains even over the 5 year period.
