what we do
Integrity Management Services
RCP has earned a worldwide reputation for providing high-quality, highly effective integrity management
services to the energy industry. Our senior staff has decades of experience, which has given us a broad,
deep understanding of the operational integrity issues our clients face.
As a result, RCP offers a comprehensive range of services including program development, HCA analysis, class
location, auditing and compliance verification as well as implementation assistance and ongoing, long-term
support for both Hazardous Liquid and Natural Gas pipeline systems.
Our auditing and compliance verification process has a proven track record assisting clients in identifying
gaps and preparing them for state and federal inspections. RCP also provides audit support during agency
RCP has extensive expertise in determining and managing the relative risk (both probability and
consequences) for both pipeline and underground gas storage systems consistent with current DOT and
state rulemakings and requirements.
ILI Project Management & Data Analysis
RCP's ILI Project management services range from pre inspection planning, developing specifications and
standards, vendor selection, process and procedures audits, to comprehensive analysis of output data,
anomaly mitigation recommendations and compliance verification.
IM Auditing & Compliance Verification
Our auditing and compliance verification process has a proven track record assisting clients in
identifying gaps and preparing them for state and federal inspections. RCP also provides audit
support during agency inspections as well as post audit response services.
IMP Program Development & Maintenance
RCP expertise and experience developing and maintaining Integrity Management Programs is second
to none, having provided IMP services for companies ranging from small private operating companies
and industrial facilities to Fortune 500 oil & gas companies. Over 80 Pipeline Integrity Management
Plans developed by RCP have been audited by PHMSA or state agencies, and all of them successfully
Program Development & Maintenance
RCP has assisted with over 150 Pipeline Integrity Management Programs, including the development of
complete programs for companies ranging from small private operating companies and industrial
facilities to Fortune 500 oil & gas companies. Over 80 Pipeline Integrity Management Plans
developed by RCP have been audited by PHMSA or state agencies, and all of them successfully passed.
RCP developed its own HCA model to identify segments along a hazardous liquid or natural gas
transmission pipeline that could affect a High Consequence Area in accordance with 49 CFR §192.903
and §195.452. RCP’s final reports for gas pipelines include detailed findings, calculations
regarding Potential Impact Radius (PIR), and maps showing HCAs. For liquid pipelines, final report
calculations and maps show NPMS identified HCAs, pipeline centerline location and hazard buffers
generated from the air dispersion analysis; overland flow analysis and/or a waterborne transport
analysis, as applicable, capable of affecting that HCA and identification of any further action
required relative to the DOT/PHMSA’s pipeline integrity management rules.
Air Dispersion Modeling
RCP’s Air Dispersion Modeling identifies potential toxic or highly volatile liquid (HVL) vapor areas
that could affect High Consequence Areas (HCAs) in the event of a hazardous liquids release. The modeling
is done using the Automated Resource for Chemical Hazard Evaluation (ARCHIE) model to identify hazard
zones related to vapor cloud fire hazards, vapor cloud explosion hazards, flame jet hazards, and toxic
spread hazards. RCP creates a report describing the process used in the modeling, results from the
modeling and maps showing results from the modeling. The maps will show the various hazard zones as they
overlay High Consequence Areas as identified by the National Pipeline Mapping System.
RCP developed a Class Location model ideal for all sizes and lengths of natural
gas pipelines. Using a sophisticated geospatial model that works with existing structure and pipeline
data to produce clear, easy-to-read maps and tables that are customizable to meet customer needs, RCP
is capable of providing efficient, repeatable, and thoroughly documented results.
The RCP Overland Flow Model analyzes spill directions, volumes, and distances in the event of a
pipeline rupture. The Flow Model automatically calculates the volume of a spill at any point on the
pipeline, using a given response time and flow rate. From the spill point, the Flow Model combines
elevation, soil type, drainage patterns, and stream flow data together to determine the path of the
spill. If the spill intersects any unusually sensitive areas or navigable waterways, a report is
generated listing the applicable intersections. If the spill intersects a waterway or drainage, the
Flow Model will track the spill downstream and predict its flow path based on a given response time,
spill volume, and hydrographic data. The water borne transport analysis utilizes the methodology
found in 40 CFR 112 Attachment C-III. This analysis will consider transport on flowing waterways,
transport on lakes or ponds, and transport on tidal influenced areas as appropriate. By using the
HCA Trace function in the Spill Model, each affected area can be traced back to a specific spill point
on the pipeline. The spill points will be aggregated to determine pipeline covered segments.
GIS and Mapping Services
RCP has a dedicated GIS and mapping department to assist customers in conducting high consequence area (HCA)
identifications, risk assessments, class location analysis, underwater inspections, NPMS/RRC submittals,
as well as other spatial analysis projects. RCP is a Platinum Esri Business Partner which allows RCP to
provide a better service to our clients with access to a larger knowledge base of Esri and related
products, including the complete suite of ArcGIS products. RCP GIS and mapping services include Pipeline &
Instrument Drawings, Survey Interpretation. Cartography & Custom Mapping, Land Mapping, Aerial Photography
and Presentation Materials.
RCP’s methodology for identifying potential threats to pipelines varies from using a simple matrix to
help quantify the synergistic effect in common threat interactions to complex algorithms including
probabilistic or deterministic models. RCPs analysis takes into consideration the primary threat
conditions identified in ASME B31.8S which fall into three separate categories; Time-Dependent
Threats Resident Threats and Time-Independent Threats.
Ongoing Integrity Management Support Services
RCP offers a wide range of ongoing integrity management services, ranging from Integrity Management
Methods Implementation and Baseline Integrity Assessments - which includes developing criteria for
determining repair and remediation actions, identifying preventative and mitigation methods, determining
assessment methodology, and assessment prioritization selection criteria - to anomaly tracking, ILI
project management, and data integration/analysis.
