MK11 SEIE Servicing

Ensuring Long-Term Reliability and Submariner Safety

Regular, expert servicing is crucial to maintaining the full operational capability of the MK11 Submarine Escape Immersion Equipment (SEIE). Trusted by over 20 of the world’s leading navies, the MK11 SEIE requires precise, scheduled maintenance to guarantee submariner safety and readiness in the most critical situations.

Recommended Servicing Schedule:

To maintain the MK11 SEIE’s 10-year service life and operational readiness, it is essential to adhere to these recommended service intervals:

First Service (25-35 Months):
This service includes a detailed inspection of the suit, liferaft, CO2 cylinder, and critical components to ensure they are in optimal condition for use in emergency situations.

Second Service (70-80 Months):
This service involves a more extensive inspection and the replacement of vital components, including the CO2 cylinder and liferaft operating mechanisms, to guarantee continued reliability and functionality throughout the suit’s lifespan.

Adhering to this service schedule ensures your equipment is always ready for deployment, meeting rigorous safety standards and maintaining the highest level of protection for submariners.
