The bulk carrier heavy-duty lifting service involves the safe loading and unloading of oversized and overweight cargoes, and special attention should be paid to the following aspects:

1. **Professional equipment**:
– Use lifting equipment suitable for heavy-duty cargoes, such as heavy cranes, special cranes, etc., to ensure sufficient load-bearing capacity.

2. **Detailed operation plan**:
– Develop a detailed lifting plan, including lifting paths, loading and unloading sequences, and expected risk assessments to ensure safety and efficiency.

3. **Safety assessment**:
– Conduct a comprehensive assessment of the loading and unloading site to ensure that the ground is stable and avoid damage to the hull or cargo.

4. **Technicians**:
– Equipped with experienced lifting technicians to ensure that the operation meets safety standards and can handle emergencies in a timely manner.

5. **Cargo reinforcement**:
– Properly tie and reinforce heavy-duty cargoes to prevent displacement or tilting during the lifting process.

6. **On-site monitoring**:
– During the operation, real-time monitoring and communication are carried out to ensure that all personnel are coordinated and reduce risks.

7. **Emergency measures**:
– Develop emergency plans to ensure rapid response and reduce losses in the event of an accident.

8. **Acceptance and records**:
– After the lifting is completed, check and record the cargo to ensure that the cargo is intact and conduct follow-up tracking.

Through the above measures, bulk carrier heavy-duty lifting operations can maximize the safety and efficiency of cargo. If you have specific project requirements or questions, please feel free to discuss further!
