Overview

The objective of this workshop is to develop and incorporate safety requirements into trials planning, as part of the activity to realise evidence for the safety case.  In addition, to consider the safety of the trials themselves and the role of safety in trials development

Task

Developing the ITEAP

Update the table below for each SRD requirement selected, using the dropdown box, to identify:

  • How the requirement will be verified (design, test, calculation, inspection, etc).
  • Detail how the verification will be undertaken (e.g. a test plan).
  • Define the acceptance (pass/fail) criteria.
  • State when in the CADMID cycle the verification will be undertaken (this could happen at several stages, depending on the test).
  • Identify if a SCR is required to support the verification assessment.

344 The SSTS must be designed wherever possible so that all risks are no higher than Tolerable and ALARP. If risks cannot be minimised to Tolerable and ALARP through design, other mitigations should be used. Hazard Log Review, Risk Reviews As Oil Rig and thus Oil SSTS move towards IOC (i.e. in-service) , we will seek input from Operator & Maintainer input (assuming Oil Rig team established) for their SQEP i.o.t review our Tolerable/ALARP statements. All Risks are Tolerable/ALARP Assessment, Manufacture, Concept, In-Service, Disposal, Demonstration Yes
345 The SSTS shall be a capable of operating with the design pressure design envelope of greater than 8 bar and less than 20 bar and have means to isolate and shut itself down when pressures are outwith the design range. Factory Acceptance Test (valves?), STW and Test & Trials, Calculation of Meeting the Required Timescales of the System and Components. Factory Tests in Isolation and Commission Trial at end of Manufacture Phase prior to IOC. Analytical Confidence > Pressure Function Test(s) Assessment, Manufacture, Demonstration No
346 The SSTS shall be able to isolate from the tanker, to cease movement of oil, within 10 seconds of activation of an Emergency Stop signal being sent from any point for oil flow chain Calculation, System Design Verification, FAT, STW, Commissioning Trial Calculation of Meeting the Required Timescales of the System and Components. Factory Tests in Isolation and Commission Trial at end of Manufacture Phase prior to IOC. Analytical Confidence > Timing Actuation Test(s) Assessment, Demonstration, Manufacture No
347 The SSTS shall be able to isolate from the Well Head, to cease movement of oil, within 10 seconds of activation of an Emergency Stop signal being sent from any point for oil flow chain Documentation Review (Calculation, P&ID, SLD)? Calculation of Meeting the Required Timescales of the System and Components. Factory Tests in Isolation and Commission Trial at end of Manufacture Phase prior to IOC. Analytical Confidence > Timing Actuation Test(s) Assessment, Manufacture, Concept, In-Service, Disposal, Demonstration No
348 The SSTS shall be able to safely manage overpressure of greater than 20 Bar Calculation, System Design Verification, FAT, STW, Commissioning Trial Calculation of Meeting the Required Timescales of the System and Components. Factory Tests in Isolation and Commission Trial at end of Manufacture Phase prior to IOC. Analytical Confidence > Pressure Test(s) Assessment, Manufacture, Concept, In-Service, Disposal, Demonstration No
349 The SSTS shall comply with all relevant current and known impending EU and UK Health and Safety legislation. Design Documentation, Compliance Matrix Legislation Compliance Matrix, Certificates of compliance with relevant standards (e.g., CE marking, UKCA marking). Test reports or audit results demonstrating adherence to legal and regulatory requirements. Declarations of conformity. Assessment, Manufacture, Concept, In-Service, Disposal, Demonstration No
350 The Systems safety target for an catastrophic repercussions per year is <1E-6. The SSTS shall met the Safety target. The System shall provide the evidence and the documentation to show that the safety targets have been achieved. NLIMS (RN Incident Mgmt System), RIDDOR, Hazard Log, Fault Tree Analysis Assessment, Manufacture, Concept, In-Service, Disposal, Demonstration No

Trials – Hazard Identification

Before trails are undertaken, it may be necessary to undertake hazard identification and assessment to ensure the trials can be conducted safely. Consider your SRD requirements above and those associated with the pressure requirements of the OIL SSTS, or an element of. Develop your Test Plan in the table above to with sufficient detail to allow the team to undertake a hazard assessment of the proposed test, using the ASEMS hazard checklist guidewords and the table below to capture your output.
