In maintaining and managing harbors and fishing ports, as well as understanding sedimentation conditions and confirming changes in seabed topography, there are cases where the conventional single-line depth surveys cannot adequately capture the irregularities and localized changes. Our company conducts marine surveys utilizing our own multi-beam sonar equipment to acquire and analyze seabed topography with high precision over large areas. 【Main Issues We Can Address】 - Depth surveys of harbors and fishing ports - Understanding sedimentation conditions and considering dredging plans - Confirming seabed topography around aging facilities - Investigating seabed changes after disasters - Creating foundational data for maintenance and management plans We have a long history of engaging in marine surveys and harbor-related operations, particularly along the coast of Fukushima Prefecture, and we can provide comprehensive support from survey planning to measurement, data analysis, and mapping. We welcome inquiries from harbor and fishing port managers, design offices, construction companies, and anyone in need of seabed topography data.

In harbor depth and shallow surveys and maintenance management operations, it is essential to accurately understand the seabed topography around the quay and navigation routes. In traditional surveys using single measurement lines, there are cases where local sedimentation and scouring conditions cannot be sufficiently grasped. Our company utilizes its own multi-beam echo sounder to acquire seabed topography in the harbor area in a planar manner. This data can be visualized and analyzed as three-dimensional data. 【Main Issues We Can Address】 - Regular depth and shallow surveys in harbor areas - Confirmation of seabed topography around quays and revetments - Understanding sedimentation conditions and preparing dredging study materials - Confirmation of current topography in navigation routes - Acquisition of basic data for developing maintenance management plans Focusing on the Tohoku coastal area, we have a track record in harbor-related operations and can provide consistent support from investigation to analysis and mapping.

In fishing ports, the progression of sediment accumulation within the harbor and the assurance of usable water depth are important issues for daily operations and maintenance management. Especially in small-scale ports, localized sediment accumulation and changes in topography can directly impact operations. Our company utilizes its own multi-beam sonar equipment to acquire the seabed topography within fishing ports in a comprehensive manner. This data can be visualized and analyzed as three-dimensional topographic data. 【Main Issues We Can Address】 - Confirmation of sediment accumulation status within the fishing port - Understanding of usable water depth - Acquisition of current topography for dredging range considerations - Confirmation of sediment progression through comparative analysis of changes over time - Creation of basic materials for maintenance management planning We have a track record of fishing port-related work, particularly along the Tohoku coast, and we propose survey plans that take regional characteristics into account.
