Offshore lifting is a typical activity in sea-based offshore building or installation operations. It is necessary for offshore installation, the installation of any process module, or the construction of any building at the operating site. It could also be employed when the shore crane is unable to lift. When a ship is on the port side, it is necessary to lift or place equipment on the side of the boat, which the shore crane cannot access. offshore lifting equipment is for shore cranes with limited capacity. Shore crane lifting capability is typically limited to 200 tonnes. Floating cranes are often used to hoist equipment that exceeds the power of the shore crane.x“
Safety measures before offshore lifting
- Before lifting, conduct a risk assessment and examine all lifting gears to verify they are in good working order.
- Ensure Mooring research and mooring line integrity and ascertain that all sea fastenings are off from the item and that it is free to be raised.
- Discuss the lifting strategy in detail. The lifting area should be entirely closed off. The lifting zone is only accessible to authorized persons.
- A lifting supervisor should be in charge of the hoisting.
- The lifting manager, rigger, locomotive engineer, and reactor operator should be on the lifting crew.
The load exerted during the lifting process must be able to endure all lifting gears engaged in the load transfer. The load exerted on the raising gear must first be estimated to determine if a lifting gear can bear a certain weight. To avoid tilting, the place of attachment of the equipment must always be in line with the center of mass of the gear.
