The external jacket foundation lifting tool, which can be operated remotely, is designed for offshore wind turbine jacket foundations with external lugs. It negates the need for human intervention increasing the safety and speed of jacket installation.
The external jacket foundation lifting tool has the following benefits;
- Design and operation requires no modification to the jacket design
- Capable of lifting 2,000t jackets
- Allows for the remote engagement and disengagement of the tool, thus removing the requirement for personnel working at height to install the tool prior to lifting
- No umbilical is required
The tool is designed to ensure that the jacket foundation is not over stressed by any temporary load cases throughout its operation (i.e. engagement, lifting etc.)
The wireless remote control will provide the remote operator with confirmation the tool is engaged and that the lifting operation is safe to commence. Three mounted cameras enable the operator to position the lifting tool into jacket lugs quickly. Guides and fins enable the system to find its fit on the lugs for the engagement of the locking pins. This removes any requirement to work at height. Release is also automated. The tool is designed to be inherently safe. The load is safely retained should the unit lose power. An integrated power supply is included, as is a secondary means of operation should the primary controls or power system fail.
The jacket foundation lifting tool provides sufficient protection on areas that physically interface with the jacket such that the tool will not cause any form of damage which may affect the performance of the jacket foundation.
