Summary¶

Massterly, a joint venture of Kongsberg Maritime and Wilhelmsen, reports that its Chief-to-Shore (C2S) project has supervised three vessels at once from a single Remote Operations Centre (ROC) workstation, staffed by one technician (O'Dwyer, 2026; Splash247, 2026). The reported progression is staged: the project launched in November 2024, gained approval for one vessel per operator in July 2025, expanded to two in October 2025, and began a three-vessel trial after internal testing in February 2026. On the first trial day one ROC technician supervised the Yara Birkeland and the Asko vessels Marit and Therese, while bridge teams remained aboard each ship. The reports give a current operational data point for the one-operator-many-ships model that the corpus has so far described only as an assumption (Remote Operation Centres Mass, Mass Roc State Of The Art); both sources are trade press and the figures are company-reported, so the article is held as emerging.

Body¶

Context¶

Two independent trade-press reports published on 5 March 2026 — Smart Maritime Network (O'Dwyer, 2026) and Splash247 (Splash247, 2026) — describe the same event: Massterly's ROC supervising three vessels simultaneously with one technician. Both are industry news, not peer-reviewed, and the operational figures originate with the company. Within this knowledge base the reports supply real-world evidence for the operator-to-vessel ratio that earlier articles treat as a design assumption: the MUNIN-era estimate of about six ships per operator recorded in Remote Operation Centres Mass, and the "one-operator-many-ships is the assumed direction of travel but not yet regulated" finding of the EMSA CMOROC state-of-the-art review in Mass Roc State Of The Art. They also give a field counterpart to the cross-domain workload limits examined in Multi Ship Remote Operations Workload Sa. Because both sources are short news articles, key points below carry no page locators.

Key Points¶

The two reports agree on the staged scaling of the C2S project. The project launched in November 2024; it was approved for shore-based operation of one vessel in July 2025, expanded to two vessels per operator in October 2025, and moved to a three-vessel trial after internal testing in February 2026 (O'Dwyer, 2026; Splash247, 2026). Both outlets describe the three-vessel supervision as a first for the company.

The reports name the same first-day configuration. ROC technician Kenneth Vestly coordinated the Yara Birkeland — described by Splash247 (2026) as the world's first fully electric, autonomous, zero-emission containership — together with the Asko vessels Marit and Therese from a shore-based facility, while bridge teams aboard each ship maintained communication and situational awareness (O'Dwyer, 2026; Splash247, 2026). The presence of bridge crews aboard places the trial at a remotely-supported rather than uncrewed level of operation, consistent with the lower IMO degrees of autonomy set out in Remote Operation Centres Mass.

Both reports describe the ROC as a replica of the ship's bridge — alarms, camera feeds, and General Arrangement (GA) drawings — supplemented by new visualisations and dashboards developed with Kongsberg Maritime (O'Dwyer, 2026; Splash247, 2026). This matches the "replicate the bridge ashore" archetype that the CMOROC state-of-the-art review identifies as the default early ROC design (Mass Roc State Of The Art). The Smart Maritime Network report attributes to ROC technician Vestly the remark that the experience "felt almost like standing on the bridge," with the dialogue with onboard crew, rather than the tools alone, making the arrangement work (O'Dwyer, 2026); Splash247 (2026) carries the same quotation.

The two reports differ in emphasis on what limits the scaling. Smart Maritime Network leads with a human-and-organisational framing: Project Coordinator Frikk Sandvik is quoted that the primary challenge is not the technology but changing procedures and building trust between sea and shore teams — "the real work is changing mindsets, procedures, and how sea and shore teams trust each other" (O'Dwyer, 2026). Splash247 (2026) gives less prominence to this point and instead notes that bridge space increased once one person moved ashore. Both agree on the planned next phase: smarter oversight tools built with Kongsberg Maritime — data abstraction, vessel dashboards, "traffic-light" alerts, and fleet-level monitoring (O'Dwyer, 2026; Splash247, 2026).

Conclusion¶

The two reports give consistent, current evidence that the operator-to-vessel ratio is being scaled in real operations — one operator moving from one to two to three vessels in roughly eighteen months — under a remotely-supported model with crews still aboard. This is the field counterpart to a question the corpus has held open: Remote Operation Centres Mass records the MUNIN-era assumption of about six ships per operator and asks how it holds against later workload findings, and Mass Roc State Of The Art notes the one-operator-many-ships model is the assumed direction of travel yet remains unregulated. The Massterly trial shows the ratio rising in practice ahead of any validated method for setting a safe ceiling, and the sources themselves locate the binding constraint in procedures and sea–shore trust rather than in technology (O'Dwyer, 2026). Because both reports are trade press with company-reported figures, the claim is cited as an operational data point, explicitly labelled as such, and the article is held as emerging pending independent or peer-reviewed confirmation.

Open Questions¶

The trial scaled the ratio to three vessels with crews aboard; no public method yet sets the safe ceiling for vessels per operator, and the planned ~6-ship target (MUNIN-era, see Remote Operation Centres Mass) remains empirically untested for uncrewed operation.
The reports identify procedures and sea–shore trust as the binding constraint rather than technology (O'Dwyer, 2026). How this maps onto the ROC competence and staffing model in Cmoroc Roc Competence Framework is unexamined.
Company-reported figures from trade press only; independent or peer-reviewed measurement of operator workload and situation awareness across the 1→2→3 progression is not yet available.
