Marine area survey

Marine area survey

Clarifying various current conditions and ecology of natural phenomena and living organisms! Investigating ocean conditions, water quality, sediment, and marine organisms.

We would like to introduce the "Marine Area Survey" that we conduct. We carry out various surveys from tidal flats to coastal areas and even the open sea, elucidating the ever-changing natural phenomena and the various current conditions and ecology of living organisms. In addition to environmental surveys and monitoring studies related to various developments, we will also strive for environmental conservation by re-examining the environment from various perspectives to meet diverse needs. 【Survey Items】 ■ Oceanographic conditions (waves, currents, tide levels) ■ Water quality and sediment quality ■ Marine organisms (plants, animal plankton, benthic organisms, intertidal organisms) ■ Various environmental surveys commissioned by government agencies and local governments ■ Research surveys for various research institutions *For more details, please refer to the PDF materials or feel free to contact us.

Investigation of maintenance management for marine structures and port facilities.

Investigation of maintenance management for marine structures and port facilities.

Maintenance and management of marine and port structures! Leave daily maintenance and repairs to us.

We would like to introduce our "Maintenance and Management Survey of Marine Structures and Port Facilities." We assist in the maintenance and management of marine and port structures, which are social infrastructure, by compiling survey results, developing long-term repair plans, and examining construction methods. Additionally, we create 3D image analyses and topographic maps using multi-beam sonar, allowing us to obtain extensive data to understand the current condition of the structures, which serves as foundational material for maintenance and repair planning. 【Features】 ■ Assistance with compiling survey results, long-term repair plans, and examining construction methods ■ Capable of handling everything from daily maintenance to repairs ■ Creation of 3D image analyses and topographic maps using multi-beam sonar, obtaining extensive data *For more details, please refer to the PDF materials or feel free to contact us.

Inspection and investigation using an underwater inspection robot.

Inspection and investigation using an underwater inspection robot.

An engineer with extensive knowledge of underwater structures and experience in diving inspections is in charge!

We would like to introduce our "Underwater Inspection Robot for Inspections and Surveys." We conduct inspections of underwater structures such as water intake and discharge facilities at various plants and water intake screens at dams, and we can measure the size of the target objects using a line laser. Additionally, we perform inspections of underwater structures such as water intake and discharge facilities at various plants and water intake screens at dams, as well as surveys of the distribution of underwater organisms and seagrass beds. [Types of Inspections and Surveys] ■ Inspection of water column structures and equipment ■ Inspection inside pipes and culverts ■ Environmental surveys *For more details, please refer to the PDF document or feel free to contact us.

Terrestrial survey

Terrestrial survey

Investigating the atmospheric environment, water environment, and flora and fauna! We also conduct surveys based on the Soil Contamination Countermeasures Act.

We would like to introduce the "Terrestrial Survey" that we conduct. We carry out investigations to understand the conditions of air pollutants, noise and vibration, low-frequency sounds, as well as surveys to assess water quality, including environmental hormones, in lakes, dam reservoirs, and rivers. Additionally, we conduct surveys on items related to the natural environment, such as animals and plants, carried out by personnel with specialized knowledge. 【Survey Items】 ■ Air environment survey ■ Water environment survey ■ Flora and fauna survey ■ Survey of landscapes and activities that connect people with nature ■ Soil survey *For more details, please refer to the PDF document or feel free to contact us.

Investigation of concrete structures in marine facilities

Investigation of concrete structures in marine facilities

It is very important to investigate the condition of rebar corrosion as it can lead to a decrease in structural strength!

We would like to introduce our "Survey of Concrete Structures for Marine Facilities." We conduct current condition surveys of concrete water channels and dolphins, and based on the results, we can also plan and execute repair projects. We perform visual inspections for issues such as surface delamination, peeling, exposed aggregates, cracks, and exposed rebar, as well as conducting chiseling to measure carbonation depth, rebar corrosion, and salt content. 【Activities】 ■ Visual Inspection ■ Chiseling Survey ■ Core Drilling Test ■ Underwater Concrete Technology ■ Repair Techniques for Joints and Expansion Joints *For more details, please refer to the PDF document or feel free to contact us.

Ultrasonic measurement survey of marine equipment

Ultrasonic measurement survey of marine equipment

Thickness measurement of steel structures using ultrasound, coating thickness measurement! Investigation using beam sonar is also possible.

We would like to introduce our "Ultrasonic Measurement Survey of Marine Equipment." We measure the thickness of steel materials in underwater steel structures using ultrasound, without exposing the structural components. This allows us to assess the corrosion status of the steel without taking samples. Additionally, we conduct surveys using pencil beam and multi-beam sonar to capture images of underwater structures. 【Types of Measurements and Surveys】 ■ Thickness Measurement ■ Coating Thickness Measurement ■ Surveys using Beam Sonar *For more details, please refer to the PDF document or feel free to contact us.
