Overview Underpinning and complementing the services that DOF Subsea provide to the offshore survey and construction industries, is a commitment to be the leading dimensional control survey provider. Land, Geodetic & Engineering Survey techniques have been adapted for the offshore engineering environment, which combined with specialist software and the latest modern high precision instruments, competent and experienced personnel, produces high accuracy 30 spatial information. This information plays a critical role in the installation of assets where accurate 30 relationships must be determined. Our Surveyors can report the position and orientation of survey interfaces hubs and flanges onshore prior to installation. Platform Surveys and Close Approaches © DOF Subsea AS 2016.

Using these services onshore during fabrication provides continuity during projects where an understanding of the requirements of offshore survey is crucial. We recognise the importance of as-built information to our clients. To ensure that a complete record is obtained laser scanners are used to generate point-cloud information, from which dimensionally correct CAD compatible models are produced. The point-cloud can be issued, modelled or stored digitally for future reference. Having access to this data means that even though structures may lie at depth, dimensional control information is at our finger tips. © DOF Subsea AS 2016.
