Summary¶

A Remote Operation Centre (ROC) is the shore-based facility from which Maritime Autonomous Surface Ships (MASS) are monitored, supported, and, where necessary, controlled. The concept emerged from the MUNIN project (2012-2015) and remains central to current MASS research because degrees two and three of autonomy both require remote oversight (Porathe, 2022). ROC design determines how many ships an operator can supervise, how operators maintain awareness across a fleet, and how the human regains control when automation reaches its limits. The leading proposals model large centres staffing many ships per operator under low-traffic conditions, scaling supervision down as traffic and constraints rise.

Body¶

Context¶

This article draws on four sources that together define the Remote Operation Centre as a shore-based facility for monitoring and controlling autonomous ships. Porathe (2021, 2022) sets the ROC against the IMO degrees of autonomy and reports the MUNIN-era sizing work; Lützhöft and Earthy (2023) treat the shore centre as one of the HUMANE project's core autonomy scenarios; and the EMSA CMOROC study (European Maritime Safety Agency, 2023d) specifies the ROC at the level of operational processes. The ROC is the structural hub of this knowledge base: it is the setting in which the out-of-the-loop and transparency problems of Human In The Loop Automation Transparency arise, the workstation whose one-to-many limits are examined in Multi Ship Remote Operations Workload Sa, and the workplace whose operator roles the competence work in Cmoroc Roc Competence Framework and Seafarer Skills And Competence For Mass specifies.

Key Points¶

Porathe (2022) places the ROC within the IMO scheme of four degrees of autonomy: degree one (automated processes with seafarers aboard), degree two (remotely controlled with seafarers aboard), degree three (remotely controlled without seafarers), and degree four (fully autonomous). Degrees two and three involve a remote control centre, and Porathe presumes degree four also relies on remote control as a fallback should the automatic system fail (PDF p. 3, orig. p. 692). The ROC is therefore not an artefact of one autonomy level but a persistent element across the transition.

Porathe (2021, 2022) reports the first ROC sizing from the MUNIN project (2012–2015), where he led the work package designing a shore control centre for a 200-m transatlantic Handymax bulk carrier on a UK–Venezuela route (Porathe, 2021, PDF p. 3, orig. p. 480). A cost-benefit analysis concluded the centre would have to be large: the organisational design assumed roughly 100 ships handled by three control rooms, each with six operators and one supervisor, with each operator responsible for about six ships during open-ocean, low-traffic passages, supervising fewer as traffic and constraints increased (Porathe, 2022, PDF p. 3, orig. p. 692). To keep operators in the loop, each operator would spend about ten minutes "virtually onboard" each vessel monitoring key parameters such as progress, traffic, system performance, and weather, so every ship was visited roughly once an hour (Porathe, 2021, PDF p. 6, orig. p. 483; Porathe, 2022, PDF p. 3, orig. p. 692).

Porathe (2021) frames the ROC's two tasks — monitoring and intervention — as distinct research problems, identifying situation awareness in remote monitoring, a quickly-getting-into-the-loop display, a remote operator-bridge interface, and automation transparency among eight Human Factors research tasks for MASS (PDF p. 8, orig. p. 485). The shore environment severs the direct connection between operator and vessel, so operators work entirely through sensor information, onshore instruments, screens, and new interface types (claude2026multishipresearch — see Multi Ship Remote Operations Workload Sa). Lützhöft and Earthy (2023) likewise treated the "shore-control/monitoring/support centre" as one of five core autonomy scenarios offered as open-ended prompts in the first HUMANE workshop (PDF p. 1, orig. p. 14).

The EMSA CMOROC study (European Maritime Safety Agency, 2023d) specifies what ROCs must do at the process level, defining a generic MASS-ROC process map spanning management, operational core, and support processes — voyage planning and control, cargo operations, navigation, engineering, maintenance, and malfunctions and emergencies, supported by human resources, legal, automation systems, and economic processes (PDF pp. 4–5, orig. pp. 2–3). This turns the abstract ROC concept into a defined set of operator tasks.

Conclusion¶

The four sources agree that the ROC is central and persistent across the MASS transition, but they approach it at different levels and from different periods. Porathe (2021, 2022) supplies the early quantitative sizing and the Human Factors research agenda; Lützhöft and Earthy (2023) treat the centre as a scenario for human-centred inquiry rather than a fixed design; and the EMSA CMOROC study (2023d) replaces assumption with a defined process map. The open tension is between the MUNIN-era six-ships-per-operator estimate and later workload findings, and between Porathe's design-led sizing and CMOROC's process-led specification, which underpins the competence work examined in Cmoroc Roc Competence Framework.

Open Questions¶

How does the MUNIN-era assumption of ~6 ships per operator hold up against later workload and vigilance findings? See Multi Ship Remote Operations Workload Sa.
The CMOROC final report and Appendix C (DCoS models) are deferred large PDFs; compiling them would clarify how ROC processes map to operator roles.
