Carnival Cruise Line has put Jotun’s Hull Skating Solutions aboard Carnival Pride, making the Spirit-class ship the first vessel in Carnival’s fleet to use the system and, according to industry reporting, the first cruise-sector implementation of Jotun’s full proactive hull-cleaning package. The pilot centers on an onboard HullSkater, a remotely operated robotic vehicle that travels across the underwater hull using cameras and sensors to inspect the surface and remove early marine growth before it becomes heavier fouling. The agreement extends beyond the robot itself, combining the HullSkater with a compatible hull coating, continuous condition monitoring, hull inspections, digital performance reporting and Jotun’s “always clean hull” framework. Carnival is collecting operational data aboard Carnival Pride as it evaluates the system. The cruise line says marine growth can increase propulsion power demand by as much as 25% to 30%, while propulsion represents roughly 60% of a cruise ship’s total energy consumption. Jotun also enters the Carnival trial with recent DNV verification of HSS vessels showing no measurable speed loss during the reviewed operating periods, although those results should not be read as a measured Carnival Pride fuel-saving figure.
Operator Impact Snapshot
Hull drag moves directly into propulsion demand
Carnival says marine growth can increase propulsion power demand by as much as 25% to 30% in affected conditions.
Carnival Pride remains the test vessel
The cruise line is collecting operational data before determining the broader role of the technology across its fleet.
Cleaning shifts earlier in the fouling cycle
The HullSkater is intended to remove early marine growth before heavier fouling becomes established on the underwater hull.
More hull work moves into normal operations
An onboard remotely operated unit allows inspections and proactive grooming to occur without waiting for a traditional reactive cleaning event.
Carnival Pride Pilot at a Glance
Carnival Pride HullSkater Pilot
The announced system reaches beyond a robotic cleaning device and combines coating, inspection, monitoring and performance data.
| Area | Carnival Pride Pilot | Operational Detail | Status |
|---|---|---|---|
| Vessel | Carnival Pride | First Carnival Cruise Line ship selected for Jotun Hull Skating Solutions. | ACTIVE PILOT |
| Cleaning Equipment | Jotun HullSkater | Remotely operated robotic vehicle using cameras and sensors while traveling along the underwater hull. | ONBOARD |
| Maintenance Strategy | Proactive grooming | Marine growth is targeted at an early stage rather than waiting for heavier fouling to accumulate. | IN SERVICE |
| Coating | Compatible HSS hull coating | The cleaning equipment is paired with a coating system designed to operate with the robotic grooming process. | INTEGRATED |
| Condition Data | Continuous monitoring and inspections | Hull condition information is combined with digital performance reporting rather than relying only on periodic visual checks. | MONITORED |
| Performance Reference | No measurable speed loss in Jotun's verified HSS sample | DNV reviewed HSS operating data and inspections. This is a Jotun fleet-level verification, not a Carnival Pride result. | DNV VERIFIED |
| Fleet Expansion | No wider Carnival rollout announced | Carnival is using the Pride installation to collect operating data and assess the technology. | WATCH |
