Managing Combat System Equipment Flashcards
What processes are used to manage change to combat system equipment?
What is the purpose and what are the contents of a CCU?
The purpose of a CCU is to provide advice and guidance on a piece of equipment as well as detailing its limitation for use. This is particularly important for safety related items.
All CCUs detail if the equipment supports:
- Ship Air Safety Report
- Air Traffic Management
- Safety of propulsion
- Navigational Safety
- Escape, Evacuation and rescue
The security assurance and safety assurance must be in date otherwise a new CCU is required to be issued.
CCUs also contain information on:
- Training requirements
- Defect reporting requirements
- if the equipment is under ‘special reporting’
- The OPDEF addressees
- Any additional requirements
- ERG Code
CCUs are signed by:
CSDA Safety Assurance Officer
CSDA Security Assurance Officer
CSDA Engineering Services Group load
Approving Authority
Combat System Design Authority
What is UMMS?
Unit Maintenance Management System is used by the WE Department to carry out planned maintenance and monitor defects. The maintenance is derived from ‘Reliability Centred Maintenance’ RCM
RCM is a maintenance policy that promotes equipment and service availability. The aim is to maintain specified functionality of a platforms system or equipment. Maintenance schedules are produced on the manufactures recommendation which assume the expected life of the equipment.
Departmental defects are entered into UMMS for tracking once they become long term defects (24 hrs after being entered into the defect log). They are assigned a unique number so they can be monitored and updated by the maintainers and relevant forms, such as S2022s can be submitted.
HMS IRDK is currently running a trial where all defect no matter how small are being entered into UMMS. This is to try and get a more accurate picture of the rate of defect.
What are the categories and failure modes of UMMS Maintenance?
CAT A - Within SS Capability
CAT A1 - Checklist Item (Occurring between daily and 4 monthly / usually less than 30 mins)
CAT A2 - Low Level Maintenance that is Semi-Skilled
CAT A3 - Routine Jobs (Checking oil levels while on rounds)
CAT A4 - Activity Driven Tasks
CAT B - Requires Support
CAT B1 - Underwater Engineering
CAT B2 - Completed when ship is at extended readiness
CAT B3 - SS Managed, Shoreside Supported (GPTME Cal)
CAT C - Dry Dock or Ships Lifting Facility
Failure Modes:
Safety
Environmental
Operational
Non-Operational
Explain Concessions
Concessions are requested when a task cannot be completed on time.
This can be for various reasons such as lack of equipment or ship’s programme.
When raising a concession the following information is required:
- What is the periodicity of the job?
- What is the reason the job cannot be completed?
- What is the risk of the job not being completed?
- What is the proposed corrective action?
- Mitigations to make any risks ALARP
- Any proposed changes to maintenance
- Concession expiry date
- Any contributing factors
Concession Approval:
CAT A S/E:
Concessed by SS
Approved by PA
CAT A1 S/E (Check List)
Concessed by SS
Approved by HOD
CAT A OP / Non-Op
Concessed by SS
Approved by HOD
CAT B1/2 S/E / OP / Non-OP
Concessed by COM
Approved by PA
CAT B3
Concessed by SS
Approved by PA
CAT C
concessed by COM
Approved by PA
If a job on a particular equipment is not completed and not concessed then the equipment should be taken offline. In circumstances where this is not possible or appropriate or when awaiting a concession decision, the CO is able to allow the operation of the equipment in risk. However this must be mitigated ALARP and held within the ships risk register.
How does the WE Department prepare for an FTSP?
FTSPs are dedicated times for maintenance and used to rectify OPDEFs and generally CAT B maintenance.
Programmed by Navy Command and IAW PA through life management plan, the primary purpose of an FTSP is to sustain and improve capability and availability.

What is TEMPEST and how is it managed onboard?
TEMPEST is a check of platforms unwanted transmissions of electromagnetic signals. All equipment processing secret or above data should be compliant with TEMPEST.
DE&S are the Platform TEMPEST Control Authority (PTCA) and are responsible for certifying TEMPEST compliance and communicating with shoreside authorities. They also produce the policy and standards for TEMPEST.
A TEMPEST test involves two personnel from the TEMPEST team (external) in a van with an antenna when a ship is alongside. One comes onto the ship to transmit form different equipment and another remains in the van to monitor any leaking data.
TEMPEST Assurance Schedule (TAS) is generated and maintained by the PTCA. It contains the following:
- ID
- Equipment Group
- Equipment
- Vulnerability Categories
- Assessment Activity
- Periodicity
- Last Update
Upon Completion of a TEMPEST test, a TEMPEST certificate (TC) is issued. The TC acts as the TCOs record of assessment status on all combat system equipment onboard iaw TAS. A CCU cannot be issued if a piece of equipment requiring TEMPEST testing has not be completed.
What is the purpose of assurance both within the WE Department and the Combat System?
Levels of Assurance: There are 4 levels of assurance. Level 1 is conducted within the ship and Levels 2 - 4 are conducted by other authorities.
Level 1 -
- Section Audits
- HOD/CO Rounds
- Shareholder Meetings
Level 2 -
- FOST CT
- MASC
Level 3 -
- AASV
- ESAV
- AFFTV
- SAC(E)
Level 4 -
- SPA
-OCCC
What are engineering standards and why are they important?
The criterial and practices that ensure equipment and systems are safe, efficient and reliable; and are operated and maintained for optimum performance by properly trained personnel in a clean and safe environment.
Important because:
- Safety
- Maintenance of OC
- Sound engineering practice
