The key to effective resolution of flow assurance issues is via sound production chemistry and chemical systems design, commissioning and startup.
GATE’s Chemical Systems Engineering (CSE) team is engaged in all aspects of chemical-related technology for onshore and offshore facilities. The GATE Chemical Systems team’s expertise is leveraged in all phases of capital project development to ensure that the design parameters chosen yield the best possible performance of the system.
The GATE CSE team’s support acts as a focal point to develop, manage and maintain a comprehensive chemical engineering strategy keeping in mind GATE’s systems perspective. This allows us to maximize the net value of the asset at all stages of the design, commissioning and production process.

Recent & Key Projects Involving Chemical Systems Engineering
The GATE Chemical Systems team’s support acts as a focal point to develop, manage and maintain a comprehensive chemical engineering/treatment strategy that maximizes the net value of the asset at all stages of the design, commissioning and production process.
BP – Production Chemistry Support
GATE provides in-house production chemistry support for the Horn Mountain, Atlantis and Thunder Horse assets.
Aseng Chemical Vendor Technical and Business Evaluation
GATE undertook a chemical vendor qualification process on behalf of Noble to procure the best suited chemical and chemical support for both the Aseng and Alen assets based on their fluids, and system along with their specific operational needs.
Since limited fluid samples were available for testing, chemical vendors were required to qualify during the first round of evaluation. The second round involved the technical and business evaluations performed together with the chosen chemical vendors. This was quite different from our normal chemical vendor evaluations, but proved to be successful for the client.
Chevron – Chemical Vendor Selection and Chemical System Design
GATE leverages each chemical vendors based on performance of chemical, lab, ability to meet supply demands and upsets, price, experience and key criteria important to contractor and operator.
GATE evaluated each chemical vendor for two phases of development Chemical Support during feed and pre-FEED, and Chemical Selection and Support to aid operations. The phases and all associated selection criteria are completely independent of each other; a vendor may be more suitable for pre-FEED work but does not necessarily become the best to support operations.
GATE is continuously improving the process and has done similar work for other Chevron assets. These projects opened the door for a new and interesting scope of work offered only by GATE and is of tremendous value to the client as well as the chemical vendors who have responded positively to the process we have implemented (both the vendor chosen and the ones that were not)
BHP Billiton Chemical Vendor Technical and Business Evaluation
GATE undertook a rigorous qualification process on behalf of the client to BHP to procure the best suited chemicals and chemical support for both the Neptune and Shenzi assets based on their fluids, and system along with their specific operational needs.
GATE, based on the Neptune and Shenzi system, produced a comprehensive operation guide that includes all aspects of operation including chemical systems and flow assurance, shutdown, startups and normal operations that will ensure the integrity of the system. By using a systems approach and taking into consideration every aspect of the production, the manuals will serve as a go by for the entire platform production.
Chemical Management Plan to guide operations for chemical procurement, documentation of chemical usage, and responses to any upset throughout startup and normal operations. This also includes a review of the chemical system to ensure operability, efficient use of chemical and no upsets caused by chemical system performance.
