Case Study / Secure vessel monitoring


DOF Subsea






Situational awareness monitoring


Offshore vessels


Harvest has enabled remote situational awareness for DOF Subsea during its 3-year contract with Esso Australia, decommissioning its extensive oil and gas structure in Australia’s Bass Strait. Global offshore and marine support services provider, DOF Subsea, supplies vessels, project management and teams for inspection, maintenance, and repair (IMR) operations. For this project, the client, Esso Australia required the use of Harvest’s technology onboard DOF Subsea’s Multi-Purpose Supply Vessel, ‘Skandi Darwin’ to enable situational awareness of operations. Harvest has been working with Esso since 2019, delivering a technology solution to stream live video from vessels via satellite using ultra-low bandwidth.

the problem

Decommissioning offshore facilities involves hazardous tasks for people, assets, and the environment, and requires various technical experts
to manage the process safely. DOF Subsea previously relied on manual communication or personnel onboard for understanding operations. However, manual reporting lacks comprehensive insights, and Esso Australia needed real-time access to it’s contractors activities at it’s project.

Having all decision-making personnel available onboard a vessel is expensive in cost, time, HSE risk, and environmental impact. To address this, DOF Subsea sought real-time situational awareness of its vessel operations using technology. They aimed to enable onshore and client personnel to remotely monitor vessel situations, ensuring informed decisions, technical support, and guidance when needed. The main challenge to achieving this situational awareness was the vessel’s limited satellite bandwidth.

the solution

Harvest provided a remote livestreaming solution to enable DOF Subsea and it’s clients to monitor the vessel through a reliable and secure video stream from onboard CCTV and subsea ROV cameras, allowing enhanced operational awareness and the ability to make immediate informed decisions related to the project.

The AVR2™ secure video streaming system offers plug- and-play usability, utilising ultra-low bandwidth on unreliable or congested networks. AVR2™ is a self-contained streaming solution that allows 1 channel of video to be streamed from a remote location and multicast via the AVRLive™ web viewer in real-time. DOF Subsea’s onshore project team, management and end-clients, Esso Australia can log into AVRLive™ from their own device from anywhere at any time.

AVR2™ provides SD video streaming for situational awareness over bandwidth as low as 60kbps. DOF Subsea’s video stream is secured using Harvest’s Nodestream™ proprietary protocol with 384-bit encryption, ensuring authorised users are the only ones with access to the video stream.

We deliver livestreaming solutions to enable remote support and operations operations. Asset, industry and network agnostic, our technology connects operations and people, anytime, anywhere.

the result

As a result, DOF Subsea and Esso Australia have gained reliable situational awareness of the “Skandi Darwin” operations without having to travel to the vessel and remain onboard for the duration of operations, or rely on manual reporting or communications.

The customisability of the AVR2™ system allows bandwidth to be adjusted on-the-fly according to the specific use case. This solution enabled DOF Subsea to work smarter and safer, making decisions based on real-time information while enhancing its ability to remotely monitor its operations. By leveraging technology to support the decommissioning project, DOF Subsea reduced the number of personnel required onboard the vessel, resulting in cost savings, decreased HSE exposure, further reducing unplanned downtime and minimising environmental impact.

Tangible results include:

  • Live situational awareness – 24/7 eyes on the job

  • Remote monitoring of critical operations

  • Multicast livestreaming to key project stakeholders and end-client

  • Compliance with end-client requirements 

  • Reduction in project personnel and crew required on the vessel
