The offshore Industry aims to minimize offshore works. For this reason, the water injection pack was supplied on the quayside as a Pre-Assembled Unit. After the module passed the Factory Acceptance Test, Conbit engineers prepared and managed the load out, marking the moment of the construction phase.
The main equipment used during the project’s execution consisted of the following:
For lifting and positioning the PAU
The team installed several steel components to the platform and PAU (e.g., bumpers, guides). They used a dedicated lift configuration with slings, shackles, and spreaders for each PAU stage and other parts.
For handling the lifted objects during preparation
Conbit team used several rigging equipments, such as tensioners, ropes, and shackles. They positioned Seafox 2 close to the F15-A platform to execute the complete lift job. They then delivered the PAU parts on a supply vessel to be positioned within reach of the Seafox 2 crane.
As the Seafox 2 was present during the entire work, its crane was used to lift the PAU from the supply vessel. It was first brought to the deck of the Seafox 2 for some final activities.
Once the team completed all the deck preparations, the deck crane installed the PAU at its final location. Members of the Conbit crew were present on the supply vessel, the Seafox 2, and the F15-A platform to coordinate the project.
The team completed the work during a shutdown. The Seafox 2 was present throughout the project to provide the necessary accommodation and lifting capacity.
