Abstract

Typical offshore cranes have a set of slings to connect to equipment. The main hook needs to be lowered to deck level to connect and disconnect the slings which requires man power and time and which will introduce considerable wear. The combi lifting tool is designed to be used by offshore cranes in which a crane tool can be safely and easily linked to different tools required during the installation process such as a noise mitigation screen and a hydrohammer.

Method

This tool was developed by examining the actual crane movements during a monopile installation process. The target was to reduce the amount of movements as much as possible and at the same time make the process safer and cheaper. Improving the operation for offshore contractors was the primary focus, even if this meant making adjustment to already existing installation equipment.

Results

The combi lifting tool will have a positive impact on safety, effiency, and maintenance costs of the installation process. By using the CLT, there will be less man power required for manually connecting slings between the crane and the installation equipment, making the operation safer. By removing the required man power and creating standard connections to equipment, the process will become more efficieny by reducting the total installation time by over 50%. Together with less wear and tear, this will have a direct impact on the maintenance costs of the installation equipment.

Conclusions

The offshore wind industry is looking for ways to reduce the installation costs in order to lower the levelized cost of energy in the market. The combi lifting tool will help in significantly improving safety, efficiency, and costs associated with handling equipment during installation operations.

Objectives

Delegates will learn how the installation process can be significantly improved in safety, efficiency and costs.
