Hydrographic Survey

galleyimage2.jpegAt Professional Surveys, we provide professional hydrographic and bathymetric survey services covering a broad range of hydrographic disciplines.

Our surveyors have access to a range of hydrographic survey sensors, platforms, state-of-the-art technology and software, enabling us to deliver a unique, tailored data solution to your specific needs. Survey systems are selected based on the scope of work, water depth, operating frequency, range from shore, accuracy requirements, seabed conditions, and size of vessel.

We advise you on the best approach to meet your project’s quality, accuracy, time and cost goals.

We have a qualified team of hydrographic surveyors who work in smart and efficient way through planning, processing and reporting process.

Whether the project is an inland river or waterway, a port or harbour, or an offshore site, we have the expertise and experience to satisfy the client’s project demands from within our own equipment inventory, vessel fleet and professional staff resources.

What are hydrographic/bathymetric surveys?

Hydrographic survey also known as bathymetric survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities.


What is Hydrography?

The term hydrography is  used synonymously to describe maritime cartography, which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user.

Hydrography is collected under rules which vary depending on the acceptance authority. Traditionally conducted by ships with a sounding line or echo sounding, surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow waters.


Why hydrographic surveys are important?

Hydrographic Surveys are performed for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defence, scientific research, and environmental protection.

In addition to supporting safe and efficient navigation of ships, hydrography underpins almost every other activity associated with the sea, including resource exploitation, fishing, minerals, environmental protection and management,  maritime boundary delimitation,  national marine spatial data infrastructures, recreational boating, maritime defence and security,  tsunami flood and inundation modelling, coastal zone management etc.


Uses of Implementing Hydrographic Surveys

  • Seabed bathymetric surveys and digital terrain models (DTM) for navigation assessment.
  • Support dredging operations.
  • Determine sedimentation levels or thickness.
  • Seabed habitat mapping Geophysical surveying to determine seabed sub-structure and composition.
  • Seabed sampling and geotechnical analysis.
