Cosmo Co. Ltd has issued an updated Notice Letter and a Root Cause Analysis regarding the quality issue that has been discovered in many fire doors that they manufacture, including A-60, A-0 and B-15 class doors. Cosmo Co. Ltd found that a number of delivered products had some insulation partly missing from the inside of the A-60, A-0 and B-15 class doors.
Cosmo Co. Ltd conducted an investigation, founding that cause of the problem was partially the new manufacturing equipment and processes that were introduced in November 2013. As a result, any A-60, A-0 and B-15 class door produced since then may have been affected, as well as some doors manufactured before that time.
After the investigation, Cosmo Co. Ltd developed a method in order to check the A-60, A-0 and B-15 class doors already installed within a vessel, to determine if they are affected by the manufacturing error.
Cosmo Co. Ltd has conducted fire tests on the A-0 and B-15 doors with the irregular insulation arrangements, to find out if they meet the requirements of SOLAS. The A-0 and B-15 door retests were successful and the results have been accepted by Lloyd’s Register and the MED certifying body, DNV GL.
However, an in-situ repair method for A-60 type doors has been outlined in order to comply with the SOLAS requirements, and sample repaired doors have been successfully fire tested by Cosmo Co. Ltd. The results have been accepted by LR and the MED certifying body, DNV GL, as well.
Owners and operators of vessels which have any Cosmo Co. Ltd fire doors. are advised to check with Cosmo Co. Ltd whether their vessels are affected or not by this issue. If the vessels are affected, operators should contact the local LR office for further advice.
