In construction work, managing wind speed is crucial to prevent falling accidents during crane operations. We will introduce a case study of ZEROSAI implementation at a site where "strong wind measures" is the theme in our technical proposal.

In river construction, it is important to establish a system that allows workers to evacuate quickly in the event of abnormal water discharge. We will introduce a case study of the implementation of ZEROSAI at a site with the theme of "water level measures for river construction" in our technical proposal. We will install 【N sensors】, 【battery-operated water level gauges】, and 【web cameras】 on-site. The 【disaster prevention panel】 will centrally manage the observed rainfall and water level data, camera footage, and weather forecasts for three locations within a 500m mesh of the construction site and upstream area. When a rainfall forecast exceeding the set threshold of XXm is predicted in the upstream river area, automatic alarms can be issued through the 【disaster prevention lights】 installed at the construction site, the "email notification function," and reports via 【external chat tools】. 【Specific operations】 For more details, please see the link below: https://product.sysmet.jp/exercise/k_56.html

Centralized management of wave height predictions and observations in the cloud ■Challenges on site: Key points for evaluation (Example) "The construction area has no barriers, so there are concerns that swells may arrive quickly when the east wind starts blowing, leading to work stoppages. Furthermore, during nighttime construction, the surrounding conditions cannot be visually confirmed, and if work is conducted based solely on general sea condition information, the judgment to stop work may be delayed, making it difficult for the work fleet to retreat." ■Proposal (Example) Weather and sea condition comprehensive portal site Compass PLUS (NETIS registration number QSK-210001-VE) Buoy-type small wave height observation device Digi-Jellyfish (NETIS registration number QSK-170002-VE) will be introduced. Digi-Jellyfish will be installed at the construction site to observe significant wave heights. The data will be viewed on a dedicated website, Compass PLUS, using a 4G connection. Observation data will be displayed along with forecast data in a consolidated manner on PC or tablet via Compass PLUS. If wave heights exceeding the reference value are observed or predicted, an emergency email will be automatically sent to the responsible person.

There should be no obstructions, and wind speed must be managed rigorously. Utilizing the new features of 【Compass PLUS】, we will continuously check real-time observed wind speed values along with wind speed forecasts. Additionally, we will share the same information with workers through the 【Disaster Prevention Light】 to achieve visibility across the entire site. 【Operating Environment】 〇 There should be no obstructions, and wind speed must be managed rigorously during crane operations, especially when performing caisson installation work. 【Operating Method】 〇 Manage the process while monitoring wind direction and speed forecasts on 【Compass PLUS】. 〇 During operations, monitor the observed wind direction and speed values with the 【N Sensor】 on 【Compass PLUS】. 〇 If wind speed exceeds the operational standard values, an email notification will be sent to the supervisor, and an emergency alert will be communicated to the workers through the light and sound of the 【Disaster Prevention Light】, enabling rapid communication for work stoppage. 【Purpose of Implementation】 〇 Due to crane operations, it is essential to grasp not only the forecasted wind speed but also the observed values. 〇 When the operational standard values are exceeded, information must be shared simultaneously across the entire site.

Sudden Guerrilla Rainstorms: Measures Against Linear Precipitation Zones ■Challenges on Site: Key Focus Points for Evaluation Example: "○○ Island has a subtropical climate and is occasionally hit by sudden guerrilla rainstorms. How can we implement daily weather measures to detect heavy rain in advance and take preemptive actions?" ■Example of Proposal Introduce the Natural Disaster Prevention System ZEROSAI (NETIS Registration Number QS-150021-VE). Install the [N Sensor] on-site. Utilize the [Disaster Prevention Panel] to grasp real-time weather data and pinpoint weather forecast information with a 500m mesh, enabling early work stoppage and preemptive measures. ■Effects of Implementation For example, with the [Disaster Prevention Panel], it is possible to monitor the rain volume at the site one hour ahead, updated every five minutes, along with the approach of thunderclouds 10km away. This information can be integrated with business chat for notifications. Additionally, by utilizing telephone consultation services with meteorologists, more detailed weather information can be obtained and used for project management. Example: By using the [N Sensor] installed at the construction site to acquire real-time data, it is possible to understand rainfall forecast information from one hour to a maximum of ten days ahead based on actual measurement data and weather data held by Sysmet. This enables rapid response and organization even outside of working hours and on holidays.

■On-site Issues: Focus Points for Evaluation (Example) Proposals for construction methods that consider the surrounding environment ■Proposal (Example) Utilize the 【Natural Disaster Prevention System ZEROSAI】 to conduct pinpoint weather forecasts at a 500m mesh on-site, and manage weather observations and information on warnings and alerts issued by municipalities in a centralized manner on the cloud. Install 【N Sensors】 on-site to utilize observation data to improve the accuracy of WBGT and wind speed predictions. When rainfall of 8mm/s or more is predicted on the disaster prevention board within 24 hours, notify the work supervisor and foreman via email, and automatically inform everyone on the business chat about the disaster prevention board information. Upon receiving the notification, secure the loosened soil surface and drainage channels to prevent the outflow of muddy water and sediment. Conduct on-site inspections when the daily rainfall exceeds 30mm/s. Install multiple 【Web Cameras】 provided by Sysmet Co., Ltd. at various locations (both banks of the construction body, temporary drainage inlet, and outlet) to manage on-site conditions in conjunction with weather information on the cloud.

We have received many inquiries from customers regarding a matter that was previously published in our latest news, so we are posting it again. The same text follows. We have contributed an article titled "How to Utilize Wave Height Observation and Weather Information Services" to the January 2022 issue of the journal "Working Vessels" published by the Japan Working Vessel Association. In light of the recent frequent abnormal weather, we introduce the optimal ways to utilize weather information related to marine operations and vessels, along with our NETIS registered products "Small Wave Height Observation Device Digi-Jellyfish (QSK-170002-A)" and "Comprehensive Weather and Ocean Information Portal Compass PLUS (QSK-210001-VE)." Please take a look.

The observation of wave height from the 【Digital Jellyfish】 has been shortened to 10 minutes, and a simplified wave height data that updates every minute is now also available for viewing. Previously, only wave height data updated every 20 minutes was available for viewing, but in response to requests for real-time wave height information, it is now possible to view simplified wave height data updated every minute. This allows for a more real-time confirmation of wave height trends, which can be useful for process management. It can also be used to appeal to clients that real-time wave height management is being conducted. *Note: Historical data is saved every 20 minutes.
