What can an offshore cranes do?
- Offshore cranes adapt to more complex sea conditions and are suitable for the following work:
- Offshore drilling platforms, oil platforms, supplementary living supplies, equipment and transportation of materials
- Deepwater operations such as the launch and recovery of submersibles and small yachts
- Loaded on construction vessels or semi-submersible vessels, operate in offshore environments, hoist materials and equipment
- For construction and salvage operations in ports or sheltered waters or equivalent offshore environmental conditions
What information do I need to provide when buying an offshore crane?
- Construction types of cranes such as bottom supported, semi-submersible, hull application, stationary
- SWL-safe working load, the size of the load and the distance relative to the crane
- Ambient conditions for crane applications, like the Beaufort and Sea state levels
- Type of crane boom, such as telescopic boom,knuckle boom,knuckle & telescopic boom and stiff boom
- The height of the crane above the water
- The Classification Society Certificates You Need
- Other accessories, operating equipment of the cab, whether it is equipped with air conditioning, the protection level of the Electre cabinet
What are the characteristics of cranes working at sea?
- Compared with cranes used on land, offshore cranes need to control the swing generated during load transportation to ensure their positioning accuracy and transportation efficiency.
- Offshore cranes are fixed on moving platforms such as ships, and the movement of the platform itself will have a strong impact on hoisting
- Motion at the point of lift and drop of the load is inconsistent with the motion of the crane itself
- During the working process, the cargo ship loaded by the offshore crane and the ship receiving the cargo will pitch, roll and heave with the waves, and these movements will cause the machine to oscillate when loaded
- During the lifting process, the ship floats up and down and swings left and right, which can easily cause the lifted cargo to collide with the deck, or even make the cargo fall off the hook, which will cause potential safety hazards.
- Due to the factors of the offshore environment, offshore cranes pay more attention to anti-corrosion, water release and explosion-proof measures
