Economics are the measure of engineering

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.

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.

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.

Authentication

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

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.

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.
