The aim of the GATE Commissioning team is to ensure the equipment is commissioned in a safe and controlled manner while confirming compliance with the design intent and demonstrating system and equipment performance.
The GATE Integrated Risk Management Team aims to provide solutions that target the challenges associated with offshore and marine project delivery. This includes Station Keeping, Vessel Integrity, Marine SIMOP's and incident prevention.
Project Experience
GATE Energy is providing early commissioning planning services as project is pre-FID.
GATE Energy provided full commissioning and start-up services for facility offshore Gulf of Mexico. Yard commissioning work completed in South Korea.
GATE Energy provided full commissioning and start-up services for facility offshore Gulf of Mexico. Work performed in Singapore and US. Full commissioning services including systems completion utilizing Omega PIMs. Yard phase commissioning in Singapore.
GATE Energy was responsible for pre-commissioning, commissioning, regulatory testing and vendor management for all Topsides systems of the King’s Quay FPU, both in South Korea and the United States / Gulf of Mexico. Viking, the engineering arm of GATE Energy, was contracted to assist with the development of the topsides standard operating procedures (SOPs).
GATE Energy provided umbilical commissioning planning and execution for subsea tieback to Bullwinkle facility offshore Gulf of Mexico.
GATE Energy provided full commissioning and start-up services offshore Israel. Due to various project engineering and construction delays on the Noble Energy Leviathan project, GATE was tasked with compressing seven months of onshore commissioning into only three months. GATE was able to quickly increase resources and personnel to mitigate a schedule impact and Leviathan topside left the fabrication yard one hundred percent commissioning complete for onshore scope. This greatly reduced the amount of potential offshore carry-over work and facilitated a successful offshore campaign to deliver the facility for initial start-up on time.

GATE partnered with Anadarko to execute full systems completion and commissioning services on the Lucius and Heidelberg Spars. Anadarko employed a “design one, build two” philosophy in development of these new-build, greenfield facilities. Though the Lucius project was a success in its own right, the extensive implementation of project lessons learned and carry-over of personnel led to GATE safely and successfully delivering the Heidelberg project three months ahead of schedule and significantly under budget.

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.
