Economics are the measure of engineering


www.naiad.ca

The Energy sector regards quality as an outcome that justifies the costs. The

reason is simple: the price of failure, whether a slow leak or a shutdown is a direct

hit to bottom line and a confrontation with the regulators.

The regulatory framework in particular is impervious to profit motives: people and

environment sit at the head of the priority table. Consequently, producers'

operating licenses hang in the balance with every leak, breakdown and accidents.

In that context, cutting corners and going cheap at the front end is anathema to

sustained profits over the life of a producing asset.

Domestic and foreign suppliers accustomed to valuing cost above quality are

unlikely to appreciate the ramifications of the operating environment. Producers

seek maximum quality and safety at the best price possible. They do not arrest

their commercial considerations to the lowest price whatever the quality.

The Machine Sciences Group understands the ramifications and enables

domestic and global clients to achieve these exacting expectations.

Machine Sciences Group


www.naiad.ca

The Machine Sciences Group aggregates under one roof the several engineering

fields that enter into the design, development and validation of robust, reliable

and valunomic industrial equipment operated in the Oil and Gas sector.

The foundational principle of the Group is to seek out an understanding the physics of a

system in order to make the inner workings of a design work. Engineering is not

software. Software is not expertise. And expertise is not experience.

The Group’s operating motto, economics are the measure of engineering, anchors the tools,

techniques and processes that are deployed on every project. Project execution is guided by

a relentless pursuit of excellence, defined in terms of risks of deficiency, of compromised

design integrity, of insidious cost inflators, and of warranty vulnerabilities. These risks

threaten a system’s long term profitability and operational effectiveness it

provides. Corralling those risks protects a client’s return on investment.

At NAIAD, physics rules, engineering governs, risks constrain, and economics ensue.

Advanced mechanics, applied mathematics and holistic analytical tools are marshaled to

correctly quantify a machine's design and reliability limits, its failure mode and containment

behavior, its manufacturability costs and its compliance to governing codes.

Viable Economics, Corralled Risk, Sustained Profitability, Maximize Asset Utilization

Areas of expertise


www.naiad.ca

NAIAD’s consulting approach strategy protects the client’s returns on

investment. Each client is unique, not molded, and deserving of a tailored

consulting approach that maximizes such strategic assets as profitability,

competitiveness and resiliency.

The Group's activities occur at all stages of a system's life cycle:

•Opportunity definition

•Requirements, specifications and performance targets

•Concept and product development

•System engineering and reverse engineering

•Modeling and dimensioning

•Simulations and analysis

•Modularization and optimization

•Validation and verification

•Reliability and failure mode analysis

•Patent protection

The Group is especially active in Simulations and modeling, Engineering authentication

and code certification

Simulations and modeling


www.naiad.ca

FEA, CFD and FSI fall under Analytics, the field of engineering concerned

with the simulation and modeling of the physics underlying the actual tri-

dimensional, time-dependent behavior of machines and inter-connected

systems within and without their intended operating envelopes.

Analytics rely on computational physics to model a system’s global behavior and to

resolve the interplay of all couplings arising from the reality of the operating scenario. The

approach simultaneously solves all relevant phenomena of significance to produce a full

quantification of a system’s true - and oftentimes unsuspected - reactions.

NAIAD’s Analytics are both a tool and a process embraced by Clients who grasp the

necessity of mastering the spectrum of risks inherent to the ownership and operation of

any industrial equipment.

It is, in the end, a choice that the Client must make between taming reality and gambling

on faith. Reality is hard, prickly, and finicky. Reality is fraught with risks that cannot be

cheated by simplifications. Only by corralling those risks will the Client’s return on

investment be protected.

Software always yields results; NAIAD translates them into answers

Authentication


www.naiad.ca

The Canadian energy sector features the widespread requirement of

stamping documentation with professional engineer seals (the so-called

P.Eng. stamp).

Typical documents include P&ID drawings, vessel and piping fabrication drawings,

vessel design calculations, pipe stress analysis reports, skid fabrication and lifting

drawings, process line lists, PSV lists and datasheets, all of which must bear the P.Eng.

stamp before they ship.

Regulatory bodies such as ABSA, BCSA and TSASK also require engineering

authentication of documents submitted in the pursuit of vessel, piping or fitting

registrations, which are an integral part of a supplier’s compliance obligation when

shipping equipment to Canada.

NAIAD offers domestic and international equipment suppliers a comprehensive

authentication service for all provincial jurisdictions in Canada. Design reviews,

analytical verification and P.Eng. stamping are available on a wide variety of oil and gas

equipment that include rotating equipment, pressure vessels, piping systems, tanks,

skidded packages, process equipment, heat exchangers and flare stacks, designed to

meet API, ASME or CSA codes.

Code certification


www.naiad.ca

A salient feature of the Energy sector is its emphasis on quality and reliability

for the equipment it operates. Large industrial systems running 24/7 must be

engineered within a disciplined design framework grounded and governed by

strict industry codes and standards.

ASME, API, CSA, IEE and ERCB are masters of the house. Meeting these standards is

sine qua none for any supplier aspiring to succeed in the sector. The Canadian energy

sector will suffer no code exception for the sake of cost cutting, lest it breaches the

regulatory edicts. Producers also impose their own proprietary design standards on top

of the regulatory set.

Suppliers must demonstrate the compliance of their equipment design to with all the code

and standard requirements imposed by the buyers. The proof is supplied by vendor

documents bearing a professional engineer’s stamp for the province or state in which the

equipment will be operated.

A critical function of NAIAD’s Machine Science Group is to assist Clients in

demonstrating the code compliance of their equipment against national and international

codes that include AISI, ANSI, API, ASCE, ASCE, CSA, DIN, DNV, EPA, ERCB, GPSA,

ISO, IEEE, NACE and UBC.

reset from infinite cycles to 23 800 cycles.


www.naiad.ca

Reverse API 618 pulsation study

Purpose: Verify bottle sizing for out-of-envelope flow conditions

Problem: Compressor layout already built

Result: Full CFD simulation confirmed suitability of size.

Outcome: 6 days turnaround time. Packager’s schedule not

compromised.

In-field vibration of compressor skid on piles

Purpose: Determine why the entire skid is shaking.

Problem: Pile layout was incorrectly installed

Outcome: Problem originated in the lack of piles which induced a

severe vibration of the scrubber, which in turn flexed the entire

skid on the piles.

Manufacturing & Aerospace

Drilling rig re-certification Purpose: Certify lengthened mast to API 4F and 4G

Problem: Mast modified by Client without prior engineering. Field

modifications required at site in Peru.

Outcome: Created 3D model of rig from fragmentary drawings.

Produced necessary modifications to rig’s sub base.

Supervised field modifications at site over 30 day period.

Rig tested successfully on first trial.

Example set 1 of 2

Muffler choked flow analysis Purpose: Eliminate choking condition in exhaust piping

Problem: Truck-mounted muffler modified by owner without prior

engineering. Behavior of exhaust flow deviated from

OEM specs. Only two test datum points available.

Outcome: Full 3D, transient CFD model created in CFX. Model

calibrated within 99.2% of pressure measurements.

Modifications designed for minimum cost impact.

Canadian Space Agency feasibility study

Purpose: Feasibility study for an Advanced Thermal Environment

Problem: ATEN to be installed in International Space Station

Outcome: Analysis of design led to proposed changes to simplify

specimen fabrication. Further analysis showed that cost

would still be prohibitive. CSA accepted Naiad’s

recommendation to abandon the project on that basis.


www.naiad.ca

Manufacturing & Aerospace

Design of multi-function stimulation trailer Purpose: Design and construct a three-in-one trailer unit

Problem: Unique configuration to include, on a single trailer a pump

unit, blender and injection system.

Outcome: 3D model and dynamic stress analysis delivered a design

that was fabricated from the get-go as a full production unit.

Example set 2 of 2

Heat transfer performance analysis of plate exchanger

Purpose: Parametric non-linear thermal-stress study

Problem: 800C incoming fluid plastically distorts cooling plate

Outcome: Analysis of design led to proposed changes to allow

deformation of the plates without overstressing the edges.

CFD results indicated that required cooling rate could not be

achieved with proposed water coolant.


www.naiad.ca

Top drive gearbox gear train analysis Purpose: Determine feasibility of up-rating from 1350 to 1500HP

Problem: Client insisted on maintaining existing configuration of

internal components.

Outcome: Configuration would not work without significant

changes to gears, bearings and splines.
