Installation and protection of subsea cables and pipelines

IMPRESUB has developed and applied in-house innovative concepts into the design and fabrication of post-trenching machines (PTM).

This includes specialised subsea trenching equipment to the burying of different sizes of pipeline in shallow and deep water, in various sea bottom soil conditions.

Specific tasks include engineering and design, development and improvement of trenching new technology, installation support for offshore structures, stabilisation and trenching of subsea pipelines and cables, protection works on cables and pipes.

Subsea non-destructive testing services

IMPRESUB’s NDT division provides a large range of inspection solutions, managing a worldwide network of partners and aiming to provide efficiently and professional service, with a range of ultimate benefits secured for the company.

The subsea pulsed eddy current (PEC) system is the core business of inspection service, as it is capable of detecting pipeline corrosion status without coating removal, pre-treating or deep cleaning. IMPRESUB offers pulsed eddy current equipment for under and above water assets.

Hydrographical and geophysical survey equipment

IMPRESUB operates state-of-the-art survey equipment, including high-resolution acquisition systems, swath bathymetry, sub-bottom profiler, side-scan sonar and complete on-board post processing capabilities.

The company offers pre-drilling site surveys for shallow gas detection, pipeline and cable route or as-laid surveys, platform site surveys and high-resolution seismic exploration. This includes the processing of hydrographical geophysical and oceanographic data, as well as the creation of high-quality charts and interpretation services using the latest software and hardware.

ROV vessels and services

IMPRESUB supplies a wide range of ROV vessels, ranging from Class 1 Visual to Class 4 Work, capable of operating in water depths up to 3,000m.

The company has performed more than 30,000h of ROV operations such as structure inspections, metrology, installation support and monitoring, trenching assistance, visual inspections, pipelines, fully instrumented surveys, and search-and-salvage operations support, drilling activities support assistance and monitoring, and pipelines touchdown monitoring.

Diving activities for air and gas saturation

IMPRESUB consistently invests in providing clients with modern diving technology and a wide range of diving support systems for air and mixed gas saturation.

The company also offers air system spreads and saturation units for teams of between four and 12. International Marine Contractors Association (IMCA) compliant, a number of systems are certified by DNV, rated for diving intervention operations at 300m.
