You can use your sea service on a trailer hopper suction dredger as part of your qualifying sea service. Stated trailer hopper suction dredger operations involve dredging operations in ports and coastal waters in Australia and around the world.
Trailer hopper suction dredgers normally operate 24 hours a day—any departure from this must be declared to us so we can determine if it will count towards your qualifying sea service.
When a trailer hopper suction dredger relocates from one port to another (anywhere in the world) under its own propulsion, its considered a normal trading vessel of its gross tonnage. You can use this service as part of your qualifying sea service for certificates of competency.
Given the nature of the work, radio communications on board are usually conducted by VHF radio and not global maritime distress and safety systems (GMDSS) even though both systems are usually fitted. We assume VHF is always used and may not accept trailer hopper suction dredger sea service for global maritime distress and safety systems (GMDSS) qualifications.
