Construction Services

We provide full range of services both for positioning on sea surface and underwater. The positioning is performed using visual, radio-navigation, satellite and hydro acoustic methods. This includes:
- 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.

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 seismoacoustic profiling
- Low frequency single- and multi-channel seismoacoustic profiling

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

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.

We use modern hydro acoustic systems, including AUV and ROV, along with visual control equipment to perform underwater facilities monitoring and inspection. These allow us to implement following tasks successfully:
- Site survey of underwater facilities by means of hydro acoustic methods and, including AUV survey
- Visual inspection of underwater facilities using AUV and ROV
- Inspection of underwater pipeline CP condition using ROV along with dedicated equipment
- Control of pipeline depth by pipeline finder installed on ROV.

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

We perform topographic survey at any scale and using any known method depending on the client requirements and object features.

We perform works for obtaining cadaster objects details and for realization of their information development.

We perform monitoring of geometric (design) parameters of industrial objects of any complexity by innovative methods.

In cooperation with our Partner we provide services of high-precision online Starfix.HP and Starfix.G2 Plus/ 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.
