Owner’s Engineering Services
Successfully Reach FID & Transform Potential into Profit
From a complex feasibility study to a full-scale, start-to-finish representative for your company, our Owners Engineering & Construction Management team gets you through FID, construction, commissioning and startup without schedule and cost blowouts. Imagine a predictable project experience.
Our GATEWay® Project-Delivery Process Delivers Better Project Outcomes
It can be daunting to navigate the maze of complex scopes, contracts and schedules. With a proven track record in delivering projects of all sizes, our GATEWay® process ensures comprehensive due diligence, precise risk assessment, and value-driven engineering. We optimize every phase to maximize returns and minimize uncertainties, giving you the confidence to make informed project investment decisions and achieve superior project outcomes.
Our Prediction Models Will Make Sure Your Project Succeeds
We recognize the need to do things differently if we are going to move the needle of project success. Predictability is crucial because it safeguards your investment, ensuring that resources are used efficiently. Wasting time, capital, and resources erodes returns and undermines sustainability.
We use Parametric prediction models that take the guesswork and bias out of schedule and cost prediction, as compared with other leading prediction methods such as Monte Carlo simulations. This leads to projects without cost and schedule blowouts.
We Create Detailed Project Scopes & Control to Maximize Your Revenue
Our team provides tight control of the schedule, scope, change orders, and overall project controls. We work to identify design options that reduce your lifecycle costs and to create detailed project scopes to prevent climbing project costs later during construction. We optimize the technical aspects of the project to decrease CAPEX and OPEX to maximize your revenue.
We not only try to eliminate issues during design and construction, but we also actively seek alternatives, and evaluate the best one for each situation instead of passing problems off to operations.
We seek to decrease lifetime costs to maximize profits. We focus on predictable project outcomes and operational reliability.
Tired of Companies Focusing on Only Detailed Design or Construction?
GATE Energy has a history of successfully keeping the end in mind. This supports joined-up thinking throughout the project lifecycle to make sure we are focused on your ultimate success and the success of your project. We have made our name by being honest, transparent, and focusing on what is best for your projects, not what is best for our pocket-book.
We are large enough to deliver projects on the scale of a multinational corporation, and at the cost, quality, and speed of a regional, specialized firm.
