The standard offshore lifting operation service refers to installing, removing, or decommissioning the main structures of fixed offshore platforms, wind generators, and other subsea facilities. The main structures of the fixed offshore platforms include the jacket and deck. The wind generators include foundations, nacelles, and towers. The subsea facilities include pipelines, cables, jumpers, umbilicals, and spools. These are the main applications of offshore lifting equipment.
When is it required?
Offshore lifting is required while installing any process module or structure at the operation site. This is also called offshore installation. Sometimes, the shore crane is unable to perform the lifting. That is where we bring the concept of offshore lifting. Offshore lifting also helps when the shore crane has reached its lifting capacity and can’t a heavier load.
Some examples of offshore lifting are:
- Offshore vessels like FPSO and FLNGs have multiple process modules such as sulfate removal and water injection systems. Hence, Offshore Module Lifting.
- An offshore jacket platform installation at the offshore site.
- Any new installation
Challenges that get in the way
Two of the main problems that come in the way are:
- The dynamic nature of the waters: if the lifting is involved on land, it is still dangerous but not as much as when it is in water. Water is constantly moving, and as we go deeper, the pressure increases beyond our imagination, which poses a risk for the offshore lifting equipment.
- Lifting gear strength: However, this problem is the one we face on land. However, the lifting is strenuous on the shore because the water is constantly moving and the loads are pretty heavy, and sometimes regular lifting does not work. That is where offshore lifting comes to work.
