Calculate sea service on floating or mobile vessels

How to calculate your sea service if you are employed upon floating production, storage and offload units (FPSOs), floating storage offload facilities (FSOs), and dynamically positioned ship type offshore industry mobile units (D/P OSIMUs).

You can use your sea service on a FPSO, FSO and D/P OSIMU as part of your qualifying sea service. Stated FPSO, FSO and D/P OSIMU operations involve work on location in offshore exploration, mining, or construction activities in Australia and around the world. While on location FPSO, FSO and D/P OSIMU are usually connected, dynamically positioned or anchored to a riser.

FPSO, FSO and D/P OSIMU 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 FPSO, FSO and D/P OSIMU relocates from one port to another (anywhere in the world) under its own propulsion, it is considered a normal trading vessel of its gross tonnage as long as the facility is a ship type with an operating engine room. You can also use this as part of your qualifying sea service for certificates of competency and global maritime distress and safety systems (GMDSS) qualifications.

If you have worked on a FPSO, FSO and D/P OSIMU, you can use this experience as part of your qualifying sea service for the following qualifications:

Qualifying sea service for a new certificate

Qualifying sea service to revalidate your certificate
