What is the "utilization coefficient" used in port construction for those involved in marine construction?
Thank you for always watching. This time, I will talk about important indicators used in port operations. Depending on the site environment, offshore construction is easily affected by waves and wind, and it is particularly necessary to carefully consider weather conditions in cost management and labor management. For this reason, there is an important keyword in offshore construction 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 called "utilization days." Additionally, the construction period (excluding preparation and cleanup) includes not only the days when work is performed (operating days) but also non-operating days (holidays, safety training days, days of inclement weather, etc.). The remaining days in a year (365 days) after excluding these non-operating days constitute the annual "operating days" for the machinery and equipment. *For more details, please visit our website or feel free to contact us.
