Professional Piping Engineering Services - Onshore & Offshore

Our specialist areas include

Onshore; Refinery, Petrochemical plants, Gas stations, LNG terminals, Pump stations etc Offshore; Wellhead platforms, Oil processing platforms, FPSO, FLNG, LNG Terminals etc Services we deliver are specified below:

Facility Piping Layouts

We specialize in the creation of process plant layouts for our clients covering the following sectors;

  • Refineries.

  • Chemical/Petrochemical Plants.

  • Fertilizer Plants.

  • Offshore Processing Facilities.

  • Power Plants.

  • Pulp and Paper Mills.

  • Food/Beverage Industries.

  • Pharmaceutical Plants.

  • Water Treatment Plants.

  • Waste Treatment Facilities

  • Pump/Compressor stations

Factors we consider in the design of process plants are:

  • Short design, engineering and construction schedules and getting the plant on stream as quickly as possible.

  • Minimizing or even eliminating field rework, which significantly increases plant construction costs.

  • Constructability.

  • Maintainability.

  • Operability.

  • Satisfying environmental requirements.

  • Minimizing costs.

Piping Materials Selection & Line Class

Little P.Eng. for Engineering Services can conduct corrosion studies and produce material selection reports including material selection diagrams or MSDs. We provide piping line classes for all process conditions or modify existing line classes to suit new process trains. We generate new line classes and can update existing Piping line classes based on new fluid services or design conditions. Little P.Eng. for Engineering Services can review any client inventory and suggest ways to re-use redundant materials for cost savings. The piping codes we specify to include:​

  • ASME B31.3

  • ASME B31.4

  • ASME B31.8

  • ASME B16.5

  • CSA Z662

  • API 6A

  • API 17D

  • API 6D

  • PD 8010-1

  • PD 5500

Piping Deliverables Checking

Little P.Eng. for Engineering Services can step into our Client shoes as owners engineers and provide quality assurance services on contractor supplied piping deliverables. We guarantee very quick turn around of documents / drawings to meet client schedules. Piping deliverables which require adequate quality checks include but not limited to:

  • Pipe stress analysis reports

  • Finite element analysis reports

  • Piping Specifications

  • Datasheets

  • Material take-offs

  • Pipe support schedules

  • General Arrangement Drawings

  • Isometrics

  • Pipe Support drawings

  • Proposals / Contractor bids

  • Material Selection Reports

Piping Supports Design

Little P.Eng. for Engineering Services has capability in the design of pipe supports determined from Caesar II or Autopipe stress analysis. Our Pipe Support design approach addresses the following objectives: ​

  • To support weight of pipe-during operation & testing

  • To take Expansion load

  • To take Wind load

  • To take Earth quake load

  • To have Noise control

  • To take Hydraulic thrust in piping

  • To support the system during Maintenance conditions

  • To support the system during Shutdown conditions

  • To support the system for Erection conditions

We can consult on behalf of our clients from design - procurement - supplier's quality assurance / control and delivery.

Piping Stress Analysis

Little P.Eng. for Engineering Services perform static and dynamic analysis of piping systems in accordance with various international codes such as ASME B31.1, CSA Z662, ASME B31.3, ASME B31.4, ASME B31.8, DNVGL-ST-F101, PD 8010-1/2, BS EN 13480. Our analysis are performed using CAESAR II and Autopipe softwares which are recognized within the industry. Our approach to stress analysis will aim to:

  • Determine piping reaction loadings onto equipment nozzles

  • Confirm all Pipe Stresses will be below defined limits of allowables

  • Mitigate the effects of thermal and pressure expansion on the piping systems

  • Capture potential support lift off scenarios for pipe supports

  • Determine piping modal / harmonic frequencies for flow induced vibrations assessment

  • Determine pipe support loads on Steelwork and Civil Structures

  • Assess the effects of potential impact loads such as slug loads and water hammer

  • Assess the effects of potential vibration sources such as wind and seismic

  • Define and create Variable and Constant Spring pipe support datasheets using a variety of supplier catalogs to suit client requirements

  • Determine anchor restraint points to resist loads on pipework and equipment

  • Review nozzle loads for compliance with international codes / standards and any limitations imposed by the equipment manufacturer
