We supply a complete geotechnical solution and services utilizing offshore heave compensated drilling, seabed sampling and in situ testing services.  

Offshore geotechnical drilling is a crucial process in the exploration and development of offshore infrastructure—like oil and gas platforms, wind farms, subsea pipelines, and undersea cables.   

It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. Oil platforms, artificial islands.

Offshore exploratory drilling includes a combination of drilling, sampling, in situ testing, as well as laboratory tests on soil and rock samples. Marine structures belong to a group of extremely complex construction projects. It is very important to be familiar with underwater geological conditions in order to predict all the potential negative impacts on construction and to prevent them on time.

Structure foundations should be grounded in marine soil in order to provide mechanical stability and to withstand the sea currents, wind and other negative impacts. In order to meet these requirements, it is necessary to understand the soil characteristics with regards to the surface and the depth of the expected significant interaction between the structure and the surrounding area. As with onshore exploratory drilling, offshore exploratory drilling is an underground research method and is often an important part of geotechnical exploration and investigation works as well as geophysical and laboratory testing.

Offshore exploratory drilling can be performed from land if the new structure is planned along the existing coast. But in most cases, it also includes the use of a vessel or pontoon for drilling equipment transport and drilling performance at the seabed.

The differences between offshore and onshore exploratory drilling:
