2023 RINA - Submarine Vulnerability Reduction WYVERN and Purple Fire

Vulnerability reduction and management has become standard practice for UK warship designs, but the same processes have not been fully applied to submarine programmes.

This paper demonstrates the potential for vulnerability reduction by assessing the impact that various design features have on the vulnerability of BMT’s WYVERN SSK design using SCL’s Purple Fire tool.

2020 INEC - A Novel Approach to the Analysis of Sinking Ships

Traditionally naval ship ultimate stability, Escape & Evacuation (E&E) analysis and operator guidance are largely produced independently.

With advances in the software used to model threats and resultant ship damage effects, a new approach is proposed whereby abandonment and dynamic sinking are modelled alongside a functional survivability analysis.

2018 RINA - Purple Fire Survivability & Lethality Assessment Tool

Survivability management is a well-established part of naval procurement. Timely and accurate advice requires efficient assessment software backed up by expert users.

This paper introduces SCL’s Purple Fire tool, which contains unique and novel features designed to facilitate the assessments required for modern platform designs, weapon programmes and operational analysis.

2018 INEC - Efficient Procurement of Low Vulnerability Warships

In recent decades the UK has made significant advances in its approach to, and its results from, the management of naval platform vulnerability.

This paper explores the history, guiding principles and assessment techniques of successful vulnerability management.

2015 RINA - The legacy of WWII vulnerability to modern warship design - lessons learned and forgotten

WWII experience taught a great deal about warship vulnerability but it would be surprising if some of the lessons had not been lost.

This paper reviews what is still relevant, reminds us of the biases of current practices and considers what has been lost but can be re-learned. While priorities may have changed, the lessons have not been invalidated.

2012 RINA - The Influence of Survivability in the Design of a Capable Affordable Surface Combatant

The platform designer has to balance a multitude of design influences with affordability. One key influence of particular interest to a warship is survivability.

This paper explores the survivability management process used for the Type 26 Global Combat Ship.
