Expert solutions for marine projects – from coasts to the open sea
Arctia is an agile and reliable partner in marine projects, whether your project area is located offshore or onshore.
Arctia’s solutions can be tailored to customers’ needs with wide marine expertise, highly versatile range of services and safe vessel fleet. At Arctia, we understand the survey challenges of the Baltic Sea in your project area.
Seabed samples are required to survey geotechnical and geochemical properties of the sediment. Sampling also provides survey data to ground-truth geophysical survey interpretations to the seabed geology.
Seabed sampling
Arctia offers sampling services offshore and onshore with a wide range of sampling equipment. Service covers continuous and undisturbed core samples from shallow sediment depths where highest sampling quality is required for environmental surveys. A high-powered vibrocorer system allows us to take continuous sediment cores from dense and unconsolidated sediments up to 6 m below the seabed.
Sampling services include planning the sampling, sampling with field observations, laboratory testing and reporting, taking into account national regulations. Combining the geophysical surveys with sampling enables representative and applicable sampling locations.
Applications
- geophysical data ground-truthing
- offshore wind farm surveys
- pipeline and cable route surveys
- pre-dredging and environmental surveys
- environmental impact assessments
- site assessment survey
Laboratory analyses
Laboratory testing is included in sampling service to determine the accuracy, determine the state of the environment and the geotechnical quality of sediment. We collaborate with accredited environmental and geotechnical laboratories to provide high quality test results.
Arctia also provides offshore and onshore field testing and sample core logging by our experts.
Drilling
Arctia provides geotechnical drilling services to support civil engineering and construction industries.
In shallow waters Arctia operates geotechnical drill rig from own barge. To respond to the offshore geotechnical drilling demand, we are preparing our own mobile heave-compensated drill rig that can be operated with Arctia’s vessel fleet in deeper waters.
Arctia provides Cone Penetration Testing (CPT) via a subcontractor. CPT’s can be deployed from our own vessels.
Applications
- ground-truthing geophysical seismic profiles
- offshore wind farm investigations
- pipeline and cable route surveys
Hydrographic and survey vessels
