Scope of Application
DOC: new Company/new ship type, 12 months. SMC: delivery/new Company responsibility/change flag, 6 months plus special extension. ISSC: A/19.4, max 6 months with no extension of that interim. MLC: specified cases, max 6 months and no second interim.
Procedure / How to Complete It
