AusOcean rigs are maritime infrastructure and must be deployed at sea only with approvals from relevant regulatory authorities. Typically a Notice to Mariners (NTM) will be issued to advise mariners of the rig’s location and flashing light sequence.

If you are constructing a rig as part of the Network Blue program, please contact us as AusOcean handles all regulatory approvals.

If for any reason you cannot carry out your maintenance duties, please contact us immediately.

1.0 Introduction

Rig and associated infrastructure maintenance is necessary to optimise equipment reliability and prevent the damage and/or loss of equipment. It is imperative that routine maintenance duties are carried out to ensure rig infrastructure is kept up to date and functional.

Important safety notes

2.1 Safety Precautions

Ensure necessary safety precautions are taken when carrying out maintenance duties.

Shark shields must be worn at all times whilst personnel are in marine waters. Shields should be in adequate condition and fully charged prior to use. Snorkels are required for surface maintenance duties, please ensure you are a  proficient swimmer and snorkeler.

If you are carrying out maintenance duties as part of the Network Blue school program,  please ensure you take all necessary safety precautions in accordance with your school’s OH&S requirements. If you are unsure, seek advice from the teacher in charge.

The specific objectives of maintenance are as follows:

4.0 Forms of Maintenance

4.1 Surface Maintenance

4.1.1 Equipment Required

4.1.2 Duties

4.2 Subsurface Maintenance

4.2.1 Equipment Required

4.3 Systematic Maintenance

Systematic maintenance consists of servicing rig equipment and infrastructure at regular intervals, in accordance with a predetermined time schedule. The aim is to detect failure or premature wear and to correct this before damage or loss of equipment occurs. All maintenance details should be recorded in this spreadsheet corresponding with the correct site. Please note these schedules may vary depending on the deployment site, however we suggest the following maintenance checks as a guide:
