A key requirement when estimating operation risks, repairing or reconstructing any hydro-technical utilities is to specify their actual condition as accurately as possible. There is no point in scheduling any reconstruction or repair works without such specification.

It`s necessary to carry out a detailed survey to obtain all technical data concerning underwater pipeline or substructures condition. Our knowledge, experience, technical capability allow our Clients to obtain reliable data to make right decision.

Certain types of work

High precision positioning for all types of offshore work

We provide full range of services both for positioning on sea surface and underwater. Positioning is performed using visual, radio-navigation, satellite and hydro acoustic methods. It includes the following:
- High accuracy positioning of surface and underwater objects for any offshore survey operations
- Utilization of specific control systems for each type of works (barge and tug management, running of hydrographic (geophysic) measurement complexes etc.
- Provision of reliable on-line communication between coordinated objects including local networking of several objects unconnected physically.

Complex hydrographic and geophysical surveys

We possess up-to-date hardware and software systems to perform detailed survey of seabed topography, integrated systems to examine the seabed and water column properties as well as prepared and experienced personnel that allow us to provide following surveys within a short time and without additional costs:
- Site bathymetric survey using multibeam echosounders
- Sonar seabed inspection
- Magnetometry
- High frequency continuous seismo-acoustic profiling
- Low frequency single- and multi-channel seismo-acoustic profiling.

Geotechnical (engineering geological) investigations

We perform geotechnical investigations required for exploration activities, installation of exploration and production drilling rigs, construction of hydro technical facilities, and laying of underwater pipelines and other utility lines. It includes the following:
- Site bathymetric survey using multibeam echosounders
- Sonar seabed inspection
- Magnetometry
- High frequency continuous seismo-acoustic profiling
- Low frequency single- and multi-channel seismo-acoustic profiling
- Probe sampling using gravity, vibro-drill and grab samplers
- Primary study of samples by means of mobile laboratory
- Storage of samples until delivery to professional laboratory
- Cone penetrometry.

Engineering hydro meteorological and ecological surveys

Our up-to-date equipment allows to fix and deliver to customer (including online) and record following hydro meteorological information:
- Wind speed and direction
- Stream speed and direction
- Wave height, velocity, direction and period
- Water conductivity, temperature and pressure
- Sea level data
- Atmosphere pressure, air humidity and temperature, as well as amount of precipitations data
Also we provide following ecological works:
- Hole mouth survey and collection of fluid samples (if necessary) using ROV
- Soil sampling
- Water sampling from different depths
- Primary study of soil and water samples by means of vessel laboratory
- Preservation and storage of samples until delivery to professional laboratory

Horizontal and vertical control for all types of work

We establish geodetic control networks regardless the object complexity, required accuracy, and coordinate system.

Differential service

In cooperation with our Partner we provide services of high-precision online Starfix.HP and Starfix.G2 / Starfix.XP2 positioning. The positioning can be executed using both control reference stations established by Svarog in Russia and an innovative solution called Satellite Differential System GPS+GLONASS (Satellite Differential GNSS - SDGNSS), based on determination of corrections to orbit and clock measurements for each satellite in GPS and GLONASS.
