A company specializing in salvage, marine engineering, surveying, and special construction

 

Survey work is carried out for planning and checking the current situation. We carry out a wide range of work, including underwater surveys of ecosystems and the environment, unexploded ordnance, and underwater structure maintenance surveys.
While there is a need for on-site surveys aimed at the maintenance and conservation of aquatic facilities, such as "on-site surveys to prepare maintenance plans," "deterioration inspection surveys," and "current status surveys" at ports, "on-site surveys to preserve the functionality of the marine product supply infrastructure" at fishing ports, and "on-site surveys to evaluate the soundness of coastal conservation facilities" on coasts, there are not many companies that can professionally carry out such work.
We utilize our experience in port civil engineering to handle various port facility surveys. Our staff and divers with specialized knowledge conduct on-site surveys and directly create drawings and evaluation sheets. We also specialize in survey and temporary construction work such as assembling SEPP boats (self-elevating work boats), boring turrets, and water scaffolding, and have a proven track record with our unique technology.

 

Bathymetric surveys (echo sounders, narrow multi-beam), shoreline surveys, GNSS surveys, and deformation surveys. These are preliminary surveys for constructing structures and progress surveys for maintenance. We provide bathymetric and shoreline surveys to measure the depth of oceans and rivers, control point surveys to confirm the amount of movement and changes of structures, and other business support. In particular, we take advantage of our company's distinctive features of ships and diving, such as 3D surveys using narrow multi-beams and GNSS surveys.
