Modeling of offshore pile driving noise using a semi-analytical variational formulation
Underwater noise radiated from offshore pile driving got much attention in recent years due to its threat to the marine environment. This study develops a three-dimensional semi-analytical method, in which the pile is modeled as an elastic thin cylindrical shell, to predict vibration and underwater acoustic radiation caused by hammer impact. The cylindrical shell, subject to the Reissner–Naghdi...
متن کاملObserved increases in offshore pile driving resistance
This paper presents 53 well-documented cases of the short-term set-up of open-ended steel pipe piles driven at two fields in the North Sea. Increases in soil resistance during driving (set-up) were observed when pile driving was re-started after delays typically ranging between 24 h and 100 h. The soil encountered at the sites consisted of overconsolidated sands and clays, where the clays varie...
متن کاملModeling of vibratory pile driving
Vibratory installation of piles and casings can be extremely economical and therefore the contractors’ preferred method of pile driving. Compared to impact pile driving it also has the advantage of reduced noise pollution. Unfortunately, this installation method is still fraught with uncertainties. The foremost question is driveability and equally important is the question of bearing capacity o...
متن کاملOn the estimation of prediction accuracy in numerical offshore pile driving noise modelling
Due to the massive, worldwide increase in the number of constructed offshore wind farms, the ecological impact of construction sites has become an important issue. Hereby, the topic of sound radiation from the needed pile driving procedures for the pile foundations of the turbines has gained a lot of attention lately. Therefore, several numerical models are currently developed to accurately pre...
متن کاملInvestigation of the Pile Aging Effect of a Fixed Offshore Platform Located in Persian Gulf using Nonlinear Soil-Pile Interactions
The study about the jacket platforms in the past has revealed that the most of the collapse failures occur due to the lack of strength of the pile foundation. However, when the jacket platforms which have been collapsed due to extreme condition were looked into, it was found that most of them had their foundations intact. These contrasting facts can be explained with the help of the phenomenon ...
