What is the "utilization coefficient" used in port construction for those involved in marine construction?

【Useful Weather Information】What is the "utilization coefficient" used in port construction?

This time, I will discuss important indicators used in port operations. Depending on the site environment, offshore construction is easily affected by waves and wind, making it particularly necessary to carefully consider weather conditions in cost management and labor management. Therefore, in offshore construction, there is an important keyword known as "utilization coefficient." This time, we will take a rough look at this "utilization coefficient." 1. What does "utilization" mean? 2. Calculation of the utilization coefficient 3. Concept of the utilization coefficient 1. What does "utilization" mean? First, "utilization" refers to the state in which machinery and equipment have been delivered to the construction site. The number of days from when the equipment is delivered to when it is removed is referred to as "utilization days." Additionally, the construction period (excluding preparation and cleanup) includes not only the days when work is performed (working days) but also non-working days (holidays, safety training days, days of inclement weather, etc.). The remaining days in a year (365 days) after excluding these non-working days constitute the annual "operating days" of the machinery and equipment. *For more details, please visit our website or feel free to contact us.

Easily obtain real-time wave heights on-site! [NETIS registration number QSK-170002-VE]

We would like to introduce the features of the NETIS registered product, the comprehensive weather and ocean portal site "Compass PLUS." By using the optional Digi-Jellyfish, you can obtain real-time observations of significant wave heights at the site. Of course, observation data can be shared among all employees, and if wave heights exceed the set threshold, you will be notified by email. 【Features】 ■ You can know the significant wave height observations on the cloud without going to the site. ■ Observation data can be shared among all employees. ■ If wave heights exceeding the threshold set at the site are observed, you will be quickly notified by email. ■ Observation data can be output in PDF or CSV format, making it usable as supporting documentation. *For more details, please refer to the PDF materials or feel free to contact us.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily visible at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

We have released a "trial version app (browser version)" that allows you to freely test the "blinking detection technology" developed using joint patent technology with Panasonic, directly in your browser. No application, installation, or membership registration is required. It measures blinking for 30 seconds using your PC's built-in camera or your smartphone's camera, displaying the number of blinks, the rate per minute, the duration of closed eyes (average and longest), and the intervals between blinks in real-time. The camera footage is processed within the browser, and neither the video nor the measurement results are sent externally. Additionally, we have started online sales of the "blinking detection app (Windows version)" that allows unlimited measurements for research and verification purposes. It supports recording and CSV output, with prices set at 33,000 yen for general users and 16,500 yen for academic institutions (tax included, per license, one-time purchase). The camera input version and the file input version are sold separately. For integration into products and services, we also offer the "blinking detection SDK" (with a one-month free trial version available).

We will begin providing a new solution for construction companies, the "Specific Voice Detection Edge AI System," utilizing the development and operational insights from the "Specific Vehicle Detection System" co-developed with Toda Corporation, starting in September 2026. This system applies the technology of the productivity-enhancing AI camera "PROLICA" to pre-learn and analyze specific voice data collected by outdoor microphones, allowing AI to detect target sounds in real-time on-site. By using voice detection, it will be possible to early detect the presence of approaching emergency vehicles even in environments where traditional visual checks or image analysis by AI cameras are difficult due to obstructions like buildings or curves. By linking with various devices and automating the control of construction vehicle departures and alerts to workers, it contributes to improving safety at construction sites and surrounding roads. ■ Main Features of This System 1. High-precision detection using voice AI 2. Safety management independent of visibility 3. Real-time processing with edge AI For more details, please check the linked page.
