Worldwide providers of mechanical plant and piping installation surveys

Replacement pipe spool, piping route and fabrication surveys

At Williamson Technical Services Limited, we provide 3D surveys of existing pipework where spools are to be fabricated to bespoke design and fitted without resorting to “hotwork”. Using electronic survey equipment, every facet of the pipework and its components can be surveyed enabling its dimensions and geometry to be reproduced during off-site fabrication.

We also specialise in route surveys for new pipework to be installed in processing plants, chemical works, oil refineries, offshore production and drilling platforms, including the location and geometry of tie in points with full dimensional and clash checks throughout a proposed route. Results of route surveys can be presented as “red line” mark ups of existing isometrics or G.As or as CAD drawings or 3D models.

We also attend fabrication workshops to provide dimensional control facilities to assist accurate construction of piping spools and structural steel components. Our services include setting up of assemblies at pre-weld stage with interim surveys prior to final welding, with the fully documented “as built” post-weld survey reports. Our computer software can provide complete statistics on the dimensional and geometrical integrity of the fabricated components, including flange deflections and bolt hole rotations.

Producing efficient results

With expertise in providing engineering surveys and alignment services for major industrial projects, we are well-positioned to provide you with bespoke services irrespective of the size of your project.

We continuously update our equipment and software in order to stay relevant in a rapidly changing environment. Thus, we are able to produce precise, reliable data each time. You can contact us for precision engineering, 3D computer modelling and structural monitoring services.
