Orbital’s mechanical, project management, construction management and QA/QC team provides a full range of services to the gas distribution industry. Our design capability ranges from repair of gas distribution pipelines, to the designing of new ones, to the design of metering and compressor stations, to river, stream and road crossings designs. Above grade crossings engage our structural engineering team and below grade crossings engage our construction management personnel who supervise the jack & bore or directional drilling contractor.
Pipe Installation & Replacement
Our design staff has designed many miles of gas distribution pipeline to either provide a new pipeline, to replace an existing deteriorated pipeline or to increase the capacity of the existing lines. In addition to design and engineering services, Orbital has provided construction management services as well and QA/QC for these projects. These pipe systems were installed by various construction methods: cut and cover, directional bore, jack and bore or on open pipe racks or bridge with support systems also designed by Orbital. Our team provides a complete solution for our clients’ challenges.
Orbital personnel have designed many pressure regulating and metering stations at the production facilities, along the pipe line route and at client supply locations. Our services include equipment selection, sizing, specification preparation and procurement services. Our electrical, mechanical and civil/structural engineering team work as an efficient, well communicated and coordinated unit under the direction of our project manager with the goal of zero errors. Our start up and testing services provide assurance that the installation is compliant with the installation specifications, drawings and permits.
Orbital’s engineering and design team has designed numerous gas compressor stations with the extraction of natural gas from rock formations, such as Marcellus, utilizing fracking technology. The design of these stations utilizes the full complement of Orbital’s multi-discipline capabilities. Our civil team will provide site development support such as grading, drainage, interior and access road and security fencing. Our structural team will design the equipment foundations, access platforms and equipment and pipe support. Our mechanical engineers provide flow analysis calculations, write system specifications, develop P&ID’s, size pipe systems and provide project management services. Our piping designers develops routing, isometric, pipe spool piece drawings and bills of material.
Above & Below Grade Crossings
Orbital’s structural staff designs modifications to existing pipe bridges or designs new ones to cross roads, streams and rivers whether in the existing production facility or in public accessible areas. Our construction management team supervises installation contractors who provide jack and bore, direct drilling or cut and cover installation services. In all these situations our primary concern is safety of the construction activities and future safe utilization of the installation. Our QA/QC inspectors provide assurance that the installation is consistent with the design drawings.
