20230710 - Update to Mandating the Use of the Safety Case Maturity Tool

Following the release of SEB 048, which mandates the use of the Safety Case Maturity Tool (SCMT) when reviewing Safety Cases, Policy Clauses 4.1 (Safety Cases) and 4.10 (Independent Review) were updated to reflect the mandate.

Since the release however, it was recognised that Policy Clause 4.10 is in fact referring to Safety and Environmental Management System (SEMS), for which SCMT is not designed.

Policy Clause 4.10 has therefore been reverted to its previous version where SCMT is not mandated for use with SEMS.

Apologies for any confusion this may have caused.
