Dolphin Energy Project Introduction

As an operator of transmission pipelines in the United Arab Emirates and offshore pipelines in Qatar, DOLPHIN ENERGY (DOLPHIN) has decided to implement a Pipeline Integrity Management System (PIMS) in order to support its existing and future operational, in-service and corporate needs with regard to the management of pipeline integrity.

The scope of the project involves various disciplines from the collection of data to the implementation of interfaces to external systems like SAP and a Document Management System. In any case a key aspect of the setup of an enterprise pipeline database is its connection to a Pipeline GIS and the implementation of algorithms inside of analytical PIMS modules.

WMS/EAM

The implementation incorporates three main interfaces to ROAIMS: • Geographical Information System • Work Order / Asset Management System • Document Management System GIS

DMS

Data Interfaces

ROAIMS

Pipeline Integrity Management Modules available to support all integrity management requirements: • Data Integration • Risk Assessment for screening and prioritization • FFP Assessment (immediate actions from defect analysis) • Corrosion Growth (future repair and inspection planning) • Diagnosis of Threats (e.g. performance of the CP system?) • GIS (Intrepid) • Task Management • …

Data Integration

• As-build data • Inspection data • Time component included (e.g. for consecutive inspections) • Audit Logs

Risk Assessment The Risk Model is structured to answer three basic questions: • Which threats are active? • Will the active threat result in a leak or a rupture? • What is the company liability in the event of a failure? To prioritize the system for maintenance and inspection activities an assessment has to be carried out both for active threats and for the consequences of a failure. • Dynamic Segmentation • Threat assessment based on rules derived from applicable codes and industry best practice, e.g. ASME B31.8s •   Suggestion of verification and mitigation procedures for all identified threats

RISK MODEL DEFINITION

Based on Client HSE Risk Management Document a Risk Assessment model is being designed

FFP Assessment The new Feature Assessment version combines ROSOFT capabilities with latest technological advantages of the ROAIMS framework. • Fully centralized database environment for all ILI and related

information (e.g. from field) • Statistics, Pivot Charts, Location Sheets (GIS) • Integration with Work Order Management System (SAP) • On-the-fly tracking of repair state (GIS) • Defect editing and updating • Comparison of assessment methods • Expression & Rules

Corrosion Growth

Process: • ILI runs girth weld alignment • Feature matching based on box

matching and clustering strategies. • Determine & verify matched features • Classify/differentiate between internal

and external corrosion features • Estimate the change in feature

dimensions • Calculate the CGR in the depth

dimension (1st order effect on part-wall to through-wall failure)

• Produce the internal and external CGRs as segmentations along the section

Outcomes: • Corrosion Rate Calculations • Remaining Life Calculation of the

pipeline

Plant Maintenance (SAP PM)

WMS Interface

• Work Order creation (Priority, Status,  Due  Date,  …)  in  ROAIMS

• Work Order updates in SAP • Dynamic update of new

attributes • Sub Tasks • MS Outlook • BizTalk • Maintenance History

Enterprise Asset Management (SAP EAM)

EAM/DMS Interface

• Asset or Tag Number as common key in all systems

• Asset status update coming from SAP to feed multiple systems

• Attribute updates in SAP triggered by GIS

• Advantages: • Integrated Systems • Fast Decision Making Process • Reduced amount of Software Systems

• Challenges: • Major integration engineering activities • Increased testing (FAT/SAT) • Advanced Know-How required

WMS/EAM/DMS Interface - Key Learnings

GIS – Intrepid

• ROAIMS and Intrepid use Common Database Model (Pipeline Open Data Standard)

• ROAIMS: Integrity Assessments, Analysis and Comparison • Intrepid: Pipeline GIS Asset Editing Tool

• Advantages: • Combined GIS / Risk Assessment Platform • DB Maintenance is reduced • Reduced amount of Software Systems/ Interfaces ( e.g. RA, CP,

DCVG, SAP, Arc GIS, Defect Assessment, etc.)

• Challenges: • Depth Know-how in house needed • Time Consuming during developing phases • Increased on-site clarifications
