Marine Survey
IOVTEC, a local company founded in 2013, provides survey services covering geophysical, construction support, hydrographic survey across met ocean and unexploded ordnance survey. With professional survey teams and sophisticated equipment, we have accumulated a wealth of track record. During the whole establishment process of offshore wind farms, it is necessary to have a sufficient well-understanding of site environment and get well-prepared to undertake an evaluation. Then we could resolve various challenges that may be encountered in the progress of wind farm development. With well-understanding of topside and underwater conditions, we also provide construction support in operation and maintenance phase. We aim to reduce the impact on environment during the whole wind farm construction period.
IOG provides professional geophysical survey services. Through sophisticated equipment and survey vessels, we deliver preliminary safety assessments of wind farms, better understanding of the environmental conditions, development risks, and also economic benefits of the windfarm. With the aim to bring efficiency to the operation and lower any working risk.
Our geophysical services include:
• Investigation and Cable Route Survey, including related surveys during pre-construction, construction, and post-construction
• Unexploded Ordnance Survey, UXO
• Cable Detection
• Scour Monitoring
• Underwater Cultural Heritage Survey
During the construction period of the wind farm, until the wind turbine construction completes, it takes a long time to carry out engineering monitoring and related construction support to ensure the quality of the project. Our construction support services can bring benefit to subsequent geotechnical construction, underwater foundation installation and cable laying.
Our construction supports include:
• PLGR-Positioning
• Piling Monitoring
• ROV(Remotely Operated Vehicle)Service
• Scour Monitoring
• Construction Supervision and Certificate Issuance (Survey)
The survey team of IOVTEC is equipped with multibeam echosounder, which could be installed at fixed points underwater, and carry out long-term monitoring. Therefore, we provide underwater environmental survey, hydrographic survey, and seafloor mapping. Through analyzing current velocity, current direction and the change of water temperature, and drift sand drift direction and particle size distribution characteristics, etc., we are able to collect required information about the environmental condition of offshore windfarm.
Our hydrographic surveys include:
• Bathymetry
• Topographic Survey
• Coastal Zone Management (CZMP) Plan Survey
Maritime climate is varied and also a challenge for offshore construction. IOVTEC provides solutions with marine observation system and data analysis. Whether in offshore or coastal environments, we provide services from preliminary project research, further survey, weather monitoring and marine weather forecast. With an aim to enhance efficiency, reduce constructional costs, and increase safety to execute offshore construction for our customers.
Our metocean surveys include:
• Buoyage system laying
• Long-term Tide Level observation and analysis
