DOF Subsea Survey & Positioning
For over 25 years we have been a major provider of detailed bathymetric and geophysical data to the oil industry.
Using leading technology, our vessels and systems supply our customers with high quality, cost-effective surveys and efficient reporting.
With our vessels, ROV, ROTV and AUV mounted equipment, we are able to acquire the highest quality (density) seabed and sub-surface data required for detail modelling and interpretation, down to 5,000 metres water depth.
We are a specialist in providing positioning control in support of its clients’ field installation projects from nearshore shallow fields to ultra-deep offshore developments.
Services include the entire range of field positioning services, umbilical, riser and flowline (URF) installations and other subsea infrastructure.
As part of this service, DOF Subsea leads the industry in providing deep water subsea metrology using acoustics and Smart Wire to measure and position spool pieces, jumpers and all subsea structures.
We have extensive experience with sophisticated data collection, processing, modelling and presentation software and methods. These systems are well known and widely used throughout the industry.
DOF Subsea has been acquiring data and producing digital bathymetric maps since the early 1980s. Our highly experienced staff perform efficient processing, interpretation and reporting of our surveys on board the vessels.
Top of the range storage systems maintain full data security and data management, making it possible to supply our customers efficiently. We are also capable of delivering a wide range of recognised CAD and GIS formats.
DOF Subsea provides precision positioning solutions for deep water wellhead installations using fully integrated DGPS and acoustic positioning with other sensors to establish wellhead height and altitude.
