Frequently Asked Questions (FAQ)

1. What is the maximum lifting capacity of this floating crane?

The main slewing crane (Unit 61#) has a Safe Working Load (SWL) of 980 kN, which is approximately 100 metric tons. The vessel is often referred to as an "80-ton" crane based on specific operational configurations, but the certification supports up to ~100 tons.

2. What are the navigation limits for this vessel?

The vessel is certified for Coastal Navigation within domestic waters. It is not designed for open ocean (international) voyages.

3. Is the crane revolving?

Yes, it is a fully revolving (slewing) crane, allowing for 360-degree rotation to handle cargo from any side of the vessel.

4. What is the condition of the certificates?

The vessel holds valid ZC certificates. The "Safety and Environmental Protection Certificate" is valid until January 5, 2029, and the crane equipment certificate is also valid until 2029.

5. What kind of power source does the crane use?

The crane operates using the vessel's electrical system, powered by three generator sets (two 40kW and one 30kW) and the main propulsion engines.
