📅Date: Thursday 5 March 2026
⏰Time: 18:00 – 20:00
📍Venue: Copthorne Hotel Plymouth
Event Overview
The aim of the Submarine Disposal Programme (SDP) is to deliver a safe, environmentally responsible and cost effective solution for the disposal of 23 of the UK’s out-of-service nuclear-powered submarines.
The SDP consists of 3 key phases: decommission, defuel and dismantle. Babcock International Group (BIG) is the Ministry of Defence (MoD) nominated lead supplier for the SDP and will undertake disposal activities at 2 nuclear licensed sites: Rosyth Royal Dockyard and Devonport Royal Dockyard.
This presentation will describe the strategic approach to the SDP, the programme structure and scope, infrastructure upgrades required to support the required disposal activities and a lookahead to future challenges. The presentation will be themed around Learning from Experience (LfE) in a complex programme and will include a reflection on the importance of Project Management (PM) processes, tools, mechanisms, stakeholder engagement and developing the personnel required to deliver the required objectives.
