STEP into the Real World

1
STEP into the Real World

• Experiences developing the Shearwater On-line
  Data Dictionary System (ODDS) in 1998

2
Shearwater Development Alliance

• A consortium that includes
• Shell Expro
• AMEC
• Heerema
• Responsible for delivering the Shearwater Project

3
Business Requirements

• Achieve electronic (STEP based) handover of
  design information
• Meets contractual requirements
• combination of electronic documents and data
• Deliver benefits within the project
• Improve data management
• Improve engineering process
• Populate Commissioning System

4
Commissioning Brent Bravo
30-40 of Construction
Check man hours could be
saved if the check list
compilation was automated
equivalent to USD 1.8-2.2m.
This is 7.5-10 of the
commissioning cost.

Technical Approach

• Electronic Documents managed through an enhanced
  FRESCO implementation
• Shearwater On-line Document System (SODS)
• Already in place
• Integration of Data Managed through implementing
  an Engineering Data Warehouse
• Online Data Dictionary System (ODDS)
• The product of this project

6
Phase 1

• A Pilot Implementation
• A solution delivery project, rather than a
  software development project
• Real Problem
• Extract data from a number of design systems and
  make it available in an integrated form for
  design data handover for commissioning and
  operations
• Real Software
• Limited Scope
• Part of a larger strategic whole - Think big -
  act small
• Short Timescale - 3 months

Organisation

• Customer Project Manager
• Peter Mayhew - AMEC
• Project Delivery Manager
• Lee Brody - Shell EXPRO
• Technical Director
• Matthew West - Shell Services International
• Supporting contractors, EuroSTEP, RevEng, CiMiO,
  and STEPData
• Data Warehouse Development
• Richard Marsh - Quillion

Approach

• A number of strands were identified
• Tactical the main thrust of this phase,
  delivering direct benefits.
• Strategic groundwork aimed at delivering
  benefits in later phases.
• Follow-up tidying up loose ends, minor
  extensions to scope.
• Exploitation ensuring benefits are harvested.

10
Achievements

• Engineering data warehouse delivered, based on
  ISO15926/AP221 (PIPPIN) data model using
  Quillions PETS product.
• Class Library used based on ETAP Class Library.
• Semi-automated interfaces developed to a number
  of systems.
• Data successfully loaded from source systems
  (flush and load).
• A number of sample browsers developed.
• Demonstration of intelligent PID created using
  CiMiOs CAD

11
Later phases

• Extended the number of systems integrated to more
  than 40
• Generated the input to the commissioning system
  WinPCS
• Generated the data for handover to operations

12
Benefits and follow on

• US4.5m on an investment of US1.5m
• Data warehouse application further developed to
  become AMECs Orbis systems used on many later
  projects
• Accumulator used to load and cleanse data into
  operations systems on numerous later projects

13
Key Learning Points

• On an Experimental Project like this, it is
  important to Do whats right rather than to Do
  what was planned, e.g.
• Expectation a number of STEP based fixed
  interfaces would be developed between source
  systems and Data Warehouse
• Outcome examination of the functionality and
  quality of many systems showed that it would be
  cheaper/better to redevelop the applications
  (later phase) than build permanent interfaces
• Consequence temporary interfaces built to
  perform data extract only

14
Key Learning Points

• Graceful degradation in usage of ISO15926 data
  model
• Most engineering systems today designed for paper
  based delivery, and on paper based techniques for
  managing information.
• Data based delivery and management of information
  requires a new generation of engineering design
  systems designed to support the delivery and
  management of engineering systems as data.

15
Conclusions

• Shearwater was one of the first projects to
  deliver benefits from the investment made by the
  Process Industries in STEP (ISO15926, AP221 and
  PIPPIN).
• The technology to support Engineering Data
  Warehouses is now leading edge, rather than
  bleeding edge.
• Many of todays systems are designed to support a
  paper based paradigm, rather than a data based
  paradigm.
• STEP was vital to the success of this project,
  but was not used directly, or in strictly
  compliant form.
