What Our Clients Are Saying…
“The services provided have been invaluable. It’s refreshing to work with a Team with the skills and training to help steer us in the right direction. The dynamics of this project’s schedule and needs have been challenging and GATE as a whole has really stepped up to meet these expectations. Look forward to a continue successful working relationship with hopes for future work.”
— BP Mad Dog 2 GOM Integration Services, Worley
“Steve Aylsworth and his whole team are an integral part of the Worley HUC team and showing a united team was always the goal on this project. I see GATE as a partner rather than our subcontractor and "our" success is around doing well together. This relationship reinforces that ethos. Thank you!”
- Worley
I would like to Recognize Clay Sparks for his tremendous work. (and the fact that he did it calmly and always with a smile). Clay came to the project under a very difficult situation where we needed him to develop a more “fit-for-purpose” commissioning plan; along with finding ways to reduce cost. Working on his own most of the time, with very little guidance and assistance from the Katmai team, he was able to put together the systems, procedures, and plans that were more in line with my expectations. Once he got offshore he was able to find further opportunities for improvement. He also found a way to bring cohesion to the various groups; and get the contractors to work better together with each other. He was a big help in making the Commissioning effort a success.

Fully Digital Process Execution with GCWS™
GCWS™ is tailored & developed specifically for Commissioning Projects
Digitalized Permit & Isolation Processing
Automated, Digital General Arrangement Maps
Customizable Permit & Report Templates
Proprietary, Cloud-based
Onsite Installation, Training, & Technical Support
The GATE Control of Work System (GCWS™) is a proprietary, cloud-based permit to work (PTW) solution designed to fulfill most oil and gas projects, yet easily adaptable for other energy construction and commissioning projects. While other systems are typically designed for the normal operations phase of a project, GATE found that these systems aren’t always suitable to construction and commissioning needs.
GCWS™ fully digitalizes the processes, procedures and deliverables needed during construction and commissioning into a customizable software package. GCWS™ includes Permit to Work (PTW), Simultaneous Operations (SIMOPS), and Lock-Out/Tag-Out (LOTO), Risk Assessment management systems for deployment onto projects where required. These tools are key to helping us achieve the “Do It Right The First Time” goal safely.
Digital Flange Management Tool
GATE also utilizes a digital flange management tool with the following attributes:
Piping and Bolting Specs are uploaded to the software
Torqueing and bolting requirements are pre-populated in ITRs
The torqueing ITRs are exported to Systems Completion Database
Constraints, Leak Registration, and Joint Breaks are recorded on tablets in the field
Joints are identified by a QR code in the field
The VM Joint Integrity Module includes a 3D model where joint status is visually indicated by color code
”Paperless” Commissioning
GATE can execute “paperless” systems completion/commissioning of an entire project (i.e. complete digitalization) by utilizing Omega PIMs CMS. The SCDB is cloud based (with local server if necessary, backed up to the cloud) and can be accessed from any mobile device (e.g. phone or tablet).
The mobile application provides a tool where the complete inspection and testing process remains digital, allowing the construction inspector and commissioning technician to carry out work on-site and synchronize back into the main database. This real time data promotes a very economical approach to Systems Completion while providing immediate feedback to management/supervisory roles during execution.
Inspection test records (ITRs) are digitally available and completed inspections are done on-site.
Offline mode allows ITRs, preservation check sheets, procedures and punch list items to be completed digitally without requiring a wifi connection.
Punch list items may be created on-site and photographs attached (including photo mark-up tool to annotate or highlight the issue).
Task assignments are traceable per status and per user / inspector allowing workload distribution and notification.
Team members are notified on-screen and via e-mail regarding all status changes on assignments and commissioning workflow.
End-users / Inspectors will be notified via e-mail when ITR Tasks status changes occur (ITR assignments, ITR completion, rejects, etc.).
All actions in the mobile application are GPS stamped for reference.
Turnover and Completion Packages (TCP) are automatically compiled and exported in PDF Format.
No need for physical copies in binders.
Digital Leak Test Packages allows for tracking completion, leaks, flange management and witness joints.
Benefits
Task assignations to track inspections and other on-site workload statuses.
Paperless documentation / reports directly delivered to the end-user.
Real time status input into planning and reporting tools.
Affiliate Services Lead to Cost Savings
Over the last several years, GATE has made a number of acquisitions to build a cadre of affiliate companies that augment the core commissioning and engineering skills of the legacy business. Amongst these, the acquisitions of BlueFin and Mid-South Rental and Completions have provided access to services that are often subcontracted to GATE during our commissioning projects. This most commonly includes flushing, filtration, bolting, torquing, hydrotesting, and leak testing.
When GATE is able to combine such services with our commissioning scope, there is typically substantial scope for cost savings on the subcontracted items, continuity of staff, increased control of risk, and certainty of schedule. In the first instance, GATE already supports the quality and HSSE management of our affiliates from the corporate level, so there is greater alignment in work processes and procedures. This reduces the time is taken to get a vendor up to speed, whilst also eliminating the one-off quality and HSSE vetting that must be undertaken with unfamiliar contractors.
This also provides a means for GATE and our affiliates to jointly develop best practice solutions for the needs of a particular project without contractual or intellectual property concerns that can typically complicate such matters.
Furthermore, it is a philosophy at GATE that we do not double-dip such projects so that GATE does not charge a mark-up on the subcontracted services. This typically saves 10 to 15% over standard contracting arrangements and is made possible by the use of an integrated corporate accounting and invoicing system.
In cases where service providers are selected by the Client, our corporate technical depth enables subject matter review of work practices and delivery procedures to ensure that our Clients are receiving appropriate levels of service that are delivered in a way that is safe, efficient, and in alignment with the overall project objectives.

10 to 15% Savings Over Standard Contracting Arrangements
This industry requirement demands both expertise in trained, accomplished personnel and best in class filtration equipment. BlueFin’s filtration units are capable of high volume and/or low volume filtration and is designed to mitigate particle contamination.
BlueFin maintains the mechanical assets required for the majority of operator’s filtration needs. From offshore pipeline abandonments and produced overboard water compliance, to onshore hydrotest water treatment and fluid handling, our team understands the full lifecycle approach to these scopes.
Hydrostatic and Pneumatic pressure testing is an accepted system integrity assessment practice for all industrial operators. Scopes of work involving pressure testing require system knowledge and competent field execution in order to deliver safe, compliant system function.
Hydrostatic pressure testing remains an industry standard pre-commissioning and commissioning practice that is a heavily regulated requirement for all branches of the oil and gas industry.
Our industrial field services are centered around both onshore and offshore process facilities and industrial plants. This includes services such as filtration, controlled bolting, hydrotesting and other skilled work.
We provide precision alignment and leveling that assures the operator’s critical component downtime and unnecessary wear is minimized and that unwarranted risks are mitigated.
For cases where safe and complete omission from flames are essential, cold cutting applications deliver safe, reliable results.
For cases where safe and complete omission from flames are essential, field machining and cold cutting applications deliver safe, reliable results.
BlueFin’s tenure and expertise in controlled bolting and joint integrity measures and monitors bolt relaxation, gasket creep, direct load loss, friction variable reduction, and direct axial force.

Seawater Injection or Waterflood Commissioning is not your typical oilfield commissioning.
While oil production process follow well-established separation and processing techniques that many operators are familiar with, waterflood systems introduce novel equipment, unfamiliar chemistry, and strict water quality requirements—making their commissioning uniquely challenging.
In today’s capital-intensive industries, delivering value without sacrificing function, quality, or reliability is paramount. Enter Value Engineering (VE), a structured, proven methodology that has been quietly transforming projects, products, and processes for over 75 years.
If you’ve been involved in capital project planning, you’ve likely seen it happen—despite detailed estimates, careful risk assessments, and robust controls, cost overruns and schedule delays remain persistent challenges.
The truth is, that most cost overruns are not caused by unexpected project-specific risks but by systemic risks—deeply embedded, structural uncertainties that traditional estimation methods fail to capture.
Prediction accuracy for extended-reach laterals and high-intensity completions is improved by applying a Gaussian Process Regression (GPR) model with a Matérn kernel that accounts for parameter space sampling bias. The method adjusts predictions based on local data density and provides uncertainty quantification, increasing reliability in underrepresented regions of the design space. Applied to wells from the Bakken Formation, the model outperforms traditional approaches and supports confident forecasting for non-standard development designs.
In the energy sector, we do not have the luxury of certainty. Whether selecting a project concept, defining a contracting strategy, or navigating a final investment decision, we are often making high-consequence choices under conditions of uncertainty, ambiguity, and competing priorities.
At GATE Energy, we have committed to transforming the way decisions are made in capital projects. We have built a structured methodology, rooted in formal decision theory, utility modeling, and risk quantification, that integrates seamlessly with front-end planning, owner’s engineering, and project execution.
This is not management by intuition. It is management by design.
In the world of capital projects, energy systems, and mission-critical operations, technology gets the spotlight. But behind every successful launch, safe startup, and flawless turnaround is a less visible force: human performance.
In this article, we look at the integrated CM-Cx service model alternative—where both functions are managed by a single entity with a unified team and goal—designed to maximize project value, minimize risk, and enhance execution efficiency.
In high-stakes industries like energy, aerospace, and healthcare, human performance is the linchpin of success. From major capital projects to real-time operations, even small misjudgments can cause delays, cost overruns, or catastrophic failures.
Past articles have explored how human bias subtly undermines quality decision-making and how resilient systems provide the adaptability needed to navigate uncertainty. Now, let’s bring these ideas together—because at their core, human performance, cognitive biases, and system resilience are deeply interconnected.
Game theory provides a framework to analyze strategic interactions between owners and contractors, who often have interdependent outcomes. Each party can choose to act competitively or cooperatively. A well-known model, the Prisoner’s Dilemma, illustrates how rational players acting in self-interest can end up worse off than if they had cooperated.
Every project professional has witnessed it—optimistic timelines that crumble, budgets that balloon, and risks that get underestimated. The culprit? More often than not, it’s human nature itself.
Behavioral science has identified over 200 cognitive and political biases that shape decision-making. In project management, ten of these biases stand out as the most impactful, silently influencing decisions, forecasts, and strategies.
In today’s fast-paced and complex world, resilience is not just about withstanding challenges- it’s about adapting and thriving in the face of them. Many systems, whether technological, organizational, or human, are designed with robustness in mind, engineered to perform within known parameters. However, when unexpected disruptions occur, these systems either extend their adaptive capacity or break down.
GATE develops and implements DST’s to mitigate high risk exposure associated with project execution.
This GATEKEEPER will discuss, at a high level, the decision support tools and methodologies that can be implemented to assist in the delivery of incident free execution of projects through focused risk mitigation in the key process safety impact areas of station keeping and vessel integrity.
Proper use of the program ensures that careful consideration is given to all potential project hazards and that suitable precautions are taken to minimize risk.
A drying campaign is crucial to the commissioning of every natural gas pipeline. When done correctly, effectively and efficiently, the results can prevent hydrate formation during start up and also protect the ongoing integrity of the pipeline.
Leak testing, commonly confused with hydrostatic testing, is a means of verifying the quality of facility construction.
It is frequently necessary to displace the contents of a pipeline or umbilical tube (fluid B) with another fluid (fluid A). If we don’t use a pig to separate the liquids, there will be mixing at the interface (axial mixing). The mixing zone requires us to overflush the line to effectively remove fluid B from the line.
Commissioning personnel have a different understanding of HSE and safety of working around live equipment. Construction sites are typically not set-up to operate a permit to work system for dynamic testing of equipment such as energizing electrical systems.
The Initial Startup is the moment of truth where everything from subsurface to topsides becomes a single entity and has to work together. Design disconnects will become apparent.
