Overview

System Requirements Document (SRD)

The URD validation criteria are used to inform the development of detailed acceptance criteria contained within the System Requirements Document (SRD) which must be sufficiently comprehensive to provide assurance that the capability requirements will be met under all operational conditions. The SRD is often used to develop the Integrated Test and Acceptance Plan (ITEAP), which details how compliance with each SRD requirement will be demonstrated.

Task Description

Your team must now develop SRD requirements, building upon on the Scenario Description and your URD requirements.

Part 1 – Develop SRD

Using the:

Populate the SRD table with Safety Requirements, noting that:

      • Each URD Safety Requirement should have one or more associated SRD Safety Requirements
      • Additional URD Safety Requirements may need to be added, to support SRD requirements identified later in the acquisition process.

To help develop a set of SRD Safety Requirements to support the workshop, you may want to include some of the following URD requirements in your SRD table.

      • The system shall be developed to recognised safety standards
      • The Target Safety Objective for the project shall be <1E-6 catastrophic repercussions per year
      • All risks shall be reduced to at least Tolerable Levels that are ALARP
      • The system shall be safe to operate at all expected pressures (<20bar>8bar)
      • The system shall provide for safe & environmentally compliant disposal of non oil product (Gas and Water)
      • The system shall comply with applicable safety legislation
      • The system shall be able to be isolated from the well head within 10 seconds
      • The system shall be able to be isolated from the tanker within 10 seconds
      • The system shall includes means to prevent overpressure

The system shall includes means to prevent over pressure

URD Table (previously populated)

wdt_ID URD ID User Requirement Type of URD (Safety/Performance) Safety Thresholds / Targets Rationale for Requirement
265
310 1 The system must comply with DEFSTAN requirements for electromagnetic effects susceptibility Safety Spurious electrical signals can lead to gas explosion
311 2 The user must be provided with a measurement of oil quantity offloaded to the tanker Performance/Safety No contamination of oil to environment Prevent overfilling/pressure of tanker
312 3 The user must be able to monitor the level of particulates within the crude oil Performance Oil meets international standards Confirms the system functions correctly
313 4 The user must be able to control the amount of oil in storage. Safety/performance Remain within storage tank capacity Prevent MARPOL incident by over filling.
314 5 To be able to pump oil from storage/SSTS to tanker at required pressure safely. Safety Must not cause over pressure of system or tanker Prevent damage to components on the rig and tankers, prevent MARPOL incidents

SRD Table (To be populated)

wdt_ID URD (Safety Requirement) SRD ID SRD (Safety Requirement)
350 The system must comply with DEFSTAN requirements for electromagnetic effects susceptibility 1 The system will be tested in accordance with DEFSTAN XX
351 The user must be able to control the amount of oil in storage The system shall provide feedback to operators of the level of oil in the storage tank once per second.

DO NOT progress on to Part 2 until you have completed the development of the OIl SSTS SRD.

Part 2 – Assess Technical Solutions

Hint: Once your SRD table has been finalised, refresh your browser before moving on to Part 2, otherwise your SRD requirements will not appear in the drop down list.

With the completed SRD, use the table below to assess the three technical proposals against your requirements and propose an initial best candidate based on requirement compliance. [Each SRD requirement will appear in the drop down box]

SRD Requirement wdt_ID Option A (5 Fully Compliant - 0 = Non Compliant) Option B (5 Fully Compliant - 0 = Non Compliant) Option C (5 Fully Compliant - 0 = Non Compliant)
