Engagement Overview
This industrial shipyard runs continuous Hot Work operations — welding, cutting, and grinding — both in open areas and in the confined spaces of ship structures. The HSE department mandates that every welding blanket must carry valid FM 4950 and EN 1869 certification before it may be used on the operational floor.
The facility had previously sourced blankets from multiple vendors. Several batches arrived without certification documents, triggering HSE holds that delayed Hot Work authorizations — and by extension, ship delivery schedules.
Customer Requirements
HSE set three non-negotiable conditions:
- Manufacturer documentation with every lot — HSE requires the manufacturer's FM 4950 Class and EN 1869 certificate to accompany each delivery
- Three or more grades available — Fiberglass (Class A, general use), Silica (Class B, high-temperature), Ceramic (Class C, extreme heat such as plasma cutting)
- ≤ 48-hour lead time for urgent orders — ship Hot Work is constrained by dry-dock schedules
