Allied Engineers offers a “full turnkey” approach towards a wide range of pipeline integrity programs that assist companies in effectively planning

and implementing asset management strategies ranging from individual line segments to full pipeline systems. Once the baseline integrity

conditions of the pipeline asset are established then our experts prioritize those issues of primary importance to client along with providing a

cost effective method for continued safe and reliable operation of the pipeline system.

ONSHORE, OFFSHORE, PIGGABLE

NON-PIGGABLE PIPELINES.

General OverviewProtection and management of pipeline assets has become a

paramount and mandatory consideration for any organization in the

energy sector. Pipeline operators, therefore, are increasingly

concerned with managing their primary assets to ensure both

competiveness and sustainability in a dynamic environment.

Operating companies are, thereby, responsible for safety, efficiency

and productivity while simultaneously fulfilling the standards outlined

by regulators and shareholders. To fulfil these objectives,

organizations have to adopt integrated strategies that outperform

standard maintenance programs.

Pipeline Integrity Evaluation Benefits:

Maintain safe, reliable operations with an increase in asset availability.

Assess the feasibility of increasing the severity of operations.

Rationalising fabrication flaws found by more rigorous in-service

inspections than those conducted during the original construction.

Re-rating of damaged equipment.

Development of inspection plans and intervals.

Life extension.

Shut-down planning.

Repair planning/schedules/retrieval.

Design of repairs.

Assessment Methodology for

Liquid Petroleum Pipelines”

DETERMINATION OF WATER ACCUMULATION

29, 30, 31Teevens Model

The Teevens model predicts both the liquid holdup and the internal corrosion

rate in two and three phase oil and gas production pipelines. It is able to predict

both the location and liquid hold-up cross-sectional area as a function of distance

and elevation change over discrete distances as dictated by Global Positioning

System (GPS) interval data collected and inputted into the model.

DETERMINATION OF SOLIDS ACCUMULATION

29, 30Teevens Model

This model predicts where solids deposition locations are most likely to occur by

calculating the solids depositional velocity of the material being accumulated. It

predicts solids accumulation as a function of distance and elevation change over

discrete distances, as dictated by global positioning satellite (GPS) interval data

collected and input into the model. The model does not predict the cumulative

amount of the material, nor does it attempt to predict underdeposit corrosion

rate behavior at this time.

CORROSION RATE MODELS

30, 31, 32, 62, 63Teevens Model

The mass transfer model is capable of yielding a general corrosion rate for

uninhibited corroding multiphase or two-phase pipeline systems, where O2,

CO2, and H2S contribute to corrosion of carbon steel pipes. The gas-liquid flow

model was updated mainly from the work of Petalas and Aziz, Taitel and Dukler,

and Barnea. The flow model predicts the flow pattern, liquid holdup, pressure

drop, and friction losses and calculates gas and liquid velocities.
