INTEGRATION SOLUTION FOR VASCO DA GAMA CLASS FRIGATES
Customer/Partner
Portuguese Navy
Description
Critical Software S.A. is working with Portuguese Navy in the development of a solution to integrate the tactical command, electronic warfare, navigation and sonar systems of the Frigates Vasco da Gama Class. The integration solution, to be installed in the first half of 2005, has been developed by Critical, after a technical viability test concluded successfully in the first trimester of 2004.
This project is part of the Portuguese Navy strategy, to implement technological solutions based on open and standardized technologies, effectively supported by national industry, thus allowing reduction of operating and modernization costs. The new solution is going to replace the systems originally supplied with the ships which were based on components discontinued by the manufacturers. The original systems were proving difficult to support and posed a risk to the Ships operational capacity.
The new equipment is based on low cost COTS components (hardware and software), strengthened to meet the operational demands of a warship, in terms of performance, reliability, availability and security. This system not only incorporates the existing functionalities of the original system, but also addresses new operational requirements which will result in a significant reduction of the operating costs associated with the original system.

C-IETP (COMPOUND INTERACTIVE ELECTRONIC TECHNICAL PUBLICATION)
Customer/Partner
Westland Helicopters
Description
C-IETP is a tool designed to browse Electronic Technical Publications, in this specific case, aircraft maintenance manuals. The browser is the only medium used by maintenance teams to make decisions about how to carry out maintenance procedures which can bear risks for maintenance technicians as well as for maintenance quality, on which the mission performance and crew depend on.
Critical is analyzing Potential Risks which possibly occurred, when a recent modification in the C-IETP took place, mainly:
- risks originating from software changes that lie behind the Electronic Technical Publication Browser, which emerged from an installed system on one computer to an installed system on a network, where publications are only updated on one server and from where clients can access the most recent information.
- risks originating from modifications performed on the creation and management process of the Electronic Technical Publication Browser, the information is visible to the maintenance technicians.
Critical will also be responsible for tailoring the Software Qualification Process currently in use by the C-IETP Software Development Team.
At the present moment, the C-IETP is in use throughout the world (e.g. Denmark, South Korea, Portugal, Canada, Oman, UK). Some examples of aircraft maintenance teams that currently use C-IETP are: Merlin HM Mk1 – Royal Navy, Merlin HC Mk3 – Royal Army, Super Linx – Portuguese Marines, UK Royal Navy, Oman Navy, EH101 – Canadian Rescue Teams, DMRH (Danish Multi-Role Helicopter) – Royal Danish Air Force.

EHUDS (SAFETY HAZARD ANALYSIS)
Customer/Partner
Westland Helicopters
Description
EHUDS (Enhanced Health and Usage Diagnostic System) is part of the UK Minister of Defense (MoD) Ground Stations Programme, and is the Ground Maintenance System for both Royal Navy (RN) Merlin Mk1 and Royal Air Force (RAF) Merlin Mk3 aircraft.
EHUDS delivers the following system functionalities, among others:
- Health and Usage Monitoring System (HUMS) data processing and display for both marks of Merlin including control of the aircraft-ground interface;
- Asset tracking and management;
- Interface with Compound Interactive Electronic Technical Publications (C-IETP);
- Interface with Logistic Information Technology System (LITS);
The data safety hazard analyses are part of the wider EHUDS Safety Case, which includes also hardware and software hazard analysis. Critical was contracted as an expert in hazard analysis to perform a safety assessment on all the business processes and support tools used by WHL to generate and populate the Reference Data and Legacy Operational Data migration into EHUDS.
The safety hazard analysis developed by Critical involved the following steps: Data capture for each Business Process and software tools supporting them, defining their basic systems/sub-systems and boundaries;Hazard identification through the use of techniques such as Fault Tree Analysis, Failure Modes, Effects and Criticality Analysis and HAZOP studies;Hazard assessment and risk reduction mitigation; Provision of auditable evidence to support risk reduction and mitigation; Set out recommendations for business processes and software design in order to reduce or eliminate risks considered unacceptable.
Critical identified possible hazards, assessed the risk associated with them providing auditable evidence that mitigation and risk reduction facilities are in place and ensure that the risks associated with the processes of operational and reference data are classified as Low as Reasonably Practicable.
