Jack-up Assisted Monopile Installation

Our client needed an investigation into the feasibility of installation monopiles using jack-up vessels alongside a noise mitigation system.

At a glance

Challenge

Our client needed an investigation into the feasibility of installing monopiles using a jack-up vessel and a noise mitigation system.

Actions

We modelled and analysed the dynamic behaviour of this installation process using OrcaFlex along with its Python API.

Benefits

Time domain analyses were performed for the four stages of the monopile installation process. The parametric set-up of the model allowed for the analysis of multiple variations of the model and enabled us to investigate every aspect of the installation process for various environmental conditions. The influence of key parameters such as soil conditions, deck load and interface stiffness on the strength of the JU and motions of the system was investigated.

Solution

We could advise our client on technical feasibility and how to mitigate associated risks. 

 

The HES Approach

De-risk

We de-risk projects by further defining installation processes, optimizing critical operations, and providing clear insights on construction risks that could impact on duration or cost.
