GGS Oil & Gas Systems

    Service & commissioning

    Whether technical service on site, repairs, spare parts, training or technical advice - GGS's mission is to guarantee the productivity, reliability, precision and security of all products and measuring systems we deliver. Our after-sales portfolio minimises downtime, increases productivity and avoids incorrect measurements - generating real cost savings over the lifetime of your installation.

    Overview

    A comprehensive approach to service - guaranteeing productivity, reliability, precision and security.

    Good service is not a matter of chance – it is the result of careful planning and optimal use of resources. The demands of installed bases with sophisticated components are always increasing, and so are the challenges of professional operation. GGS supports you with a full mix of services to maximise reliability and security of your custody-transfer installations.
    Our portfolio covers installation & commissioning/SAT, preventive maintenance, verification & validation, corrective workshop and site repair, helpdesk and remote support, on-site engineering, training and full multi-year Service Level Agreements. Each module can be delivered stand-alone or combined into a tailored contract.
    The value is measurable. A 0.1% improvement in measurement uncertainty on a 2 BSCFD gas metering station equates to roughly US$ 3.3 million per year in avoided miss-measurement – many times the cost of the service programme itself. Service is not an expense; it is one of the highest-return investments in a custody-transfer system.
