Pile driving barge offshore operation rate evaluation system and method

Abstract

The invention discloses a pile driving barge offshore operation rate evaluation system and method, and the method comprises the steps: firstly calculating the lateral time domain movement displacement, longitudinal time domain movement displacement and heaving time domain movement displacement of a movement reference point on a pile driving barge in a 180-degree wave direction based on an actual operation sea condition or a design sea condition; then, based on a set limit threshold value, calculating the combined operation probability of the pile driving barge and the mean value of the combined operation probabilities under all waves; and finally, evaluating the offshore operation rate and the operation capability of the pile driving barge. According to the scheme, the operation rate and the operation capacity of the pile driving barge under the certain sea condition can be quantitatively evaluated, the operation rate of the pile driving barge can be quantitatively given, the operationtime and the operation window period of the pile driving barge under the certain sea condition can be effectively evaluated, and a ship owner and a ship captain are guided to make reasonable work plans.

Description

technical field [0001] The invention relates to offshore pile foundation engineering technology, in particular to the offshore operation rate evaluation technology of piling ships. Background technique [0002] With the vigorous development of offshore oil and gas and wind power projects, as well as the continuous construction of cross-sea bridges and deep-sea port terminals, there are more and more large-scale foundation piles and deep-sea structure foundation pile projects. Due to the constraints and influences of many conditions such as geology and geology, and the complex construction environment and unsafe factors, in order to ensure that piling equipment can sink piles safely, quickly and accurately to the design position and depth in complex environments, the operation rate of special piling ships and work ability requirements are higher. How to evaluate the operating rate and operating capacity of piling ships is one of the keys to solving technical problems in offs...

AI Technical Summary

Problems solved by technology

[0004] When a piling ship operates in a designated area, it is usually based on the experience of the captain and crew. At present, there is no method to quantify the operating rate and operating capacity of the piling ship. There is an urgent need for a method of quantifying the operation of the piling ship to guide the captain and crew to work safely and efficiently.
