- Simple operation of crane than derricks.
- Single-man operation, derricks are more labour intensive.
- Clear deck operational views.
- Clear deck space of rigging.
- Versatility with heavy loads, and not required to de-rig.
- 360° slew and working arc when compared with limited operating areas for derricks.
- Able to plumb any point quickly making a faster load/discharge operation.
- Enclosed cabin for operator, where as the majority of derrick operators are exposed, offering greater operator protection and comfort.
- Cranes are acceptably safer to operate because of their simplicity, where derrick rigs can be overly complicated in rigging and operation.
- Cranes can easily service two hatches, or twin hatches in the fore and aft direction because of their 360° slew ability.
