ROV Services

Inspection, Maintenance and Repair (IMR)

Measuring Mooring Chain with a bespoke measurement tool.

Tamboritha provide a full suite of services to meet our clients’ subsea Inspection, Maintenance and Repair (IMR or also known as IRM) requirements. With our in-house experience, fleet of ROVs, and engineering capabilities combined with our business partnerships for survey and positioning, grouting services, inspection and vessels, Tamboritha can provide turnkey solutions for all of your IMR needs.

Tamboritha understand client requirements to perform any IMR program, from a simple jacket inspection, to full-field inspections and survey to freespan correction and even CP Anode Replacement programs in a timely, efficient and above all safe manner.

Project Management

Our experienced team of management and engineers are able to plan, prepare and execute any subsea IRM program. We deliver value to your project, developing operational and HS&E documentation, design engineering, identification of tooling requirements, securing subcontractor services and streamlined mobilisation preparation.

Preparation of the ROVs is key to a successful project. At Tamboritha, we pride ourselves in the fact that all project-specific tooling and sensors are installed on the ROV(s) in our workshop prior to mobilisation to the vessel. If further integration testing of tooling or testing of compatibility with third-party equipment is required, this is carried out in our purpose-built test tank.

More information on our full range of Project Management services can be found in our Project Management and Engineering section.

Cathodic Protection

CP Clamp

Most IMR programs require the measurement of the CP protection of the subsea assets.

Tamboritha’s ROVs are compatible with any industry-standard CP measurement system including digital continuous measurement and also using the tried and trusted Bathycorrometer® and these are typically integrated with the ROV in our workshop prior to mobilisation. Acquisition, analysis and reporting are provided by in-house personnel or sub-contractors dependent on the size and type of the project.

Tamboritha also specialise in designing, building and installing anode ground-beds and connection systems for extending the life of our clients’ subsea assets.

More information on our Cathodic Protection Services can be found in the Cathodic Protection section.
