ROV Systems
ROV Cable Solutions
RouLine manufactures custom ROV Cable solutions for underwater remotely operated vehicles (ROVs), including work-class ROVs and observation-class ROVs used in subsea inspection, offshore engineering and marine research. Our solutions include ROV Umbilical Cables and ROV Tether Cables that support power, control signal and data transmission, with optional fiber optic communication, according to the requirements of each ROV system.
ROV cable requirements vary by underwater vehicle class and application. Observation-Class ROVs often use lightweight, flexible tether cables, while Work-Class ROVs may require cables with higher tensile strength, enhanced mechanical protection and integrated power, control, data or fiber optic transmission. RouLine customizes cable construction according to project-specific electrical, mechanical and environmental requirements.

FAQ
What types of cables are used in ROV systems?
ROV systems commonly use ROV umbilical cables and ROV tether cables, depending on the vehicle configuration, deployment method and operational requirements. These cables can support power, control, signal and data transmission, with optional fiber optic communication. Cable design varies according to the ROV system architecture and the role of each cable.
What is the difference between an ROV umbilical cable and an ROV tether cable?
An ROV umbilical cable typically provides the main connection between the surface support system and subsea equipment, while an ROV tether cable connects the ROV to its power, control or communication source, depending on the system configuration. Their structures and load-bearing requirements vary with deployment arrangements, tether management systems and operating depth. The appropriate cable type should be selected according to the specific ROV setup.
Can ROV cables be customized for different subsea applications?
Yes. Custom ROV cables can be designed around project-specific electrical, mechanical and environmental requirements. Options include conductor size, power and signal core configuration, fiber optic elements, tensile strength members, steel wire armor, outer sheath materials and buoyancy characteristics. The final construction depends on the operating conditions and integration requirements of the ROV system.
What transmission functions can custom ROV cables integrate?
Custom ROV cables can combine power, control signals, communication data and fiber optic transmission in one cable, depending on system requirements. Hybrid cable designs can reduce the need for separate cables while supporting integrated ROV system connections. Conductor configuration, shielding, optical fiber type and electrical performance are selected according to the required transmission functions.
How do you select an ROV cable for deepwater operations?
ROV cable selection depends on operating depth, required tensile load, deployment and recovery method, cable length, dynamic bending, abrasion exposure and seawater conditions. Electrical requirements, data transmission capacity and buoyancy may also influence the design. For deepwater applications, cable construction should be evaluated against the actual mechanical loads and operating conditions rather than depth alone.
Can you manufacture custom ROV umbilical and tether cables for OEM projects?
Yes. RouLine supports custom ROV umbilical and tether cable manufacturing for OEMs, system integrators and subsea equipment projects. Cable designs can be developed according to project specifications, including electrical configuration, mechanical reinforcement, transmission requirements and sheath materials. Clients can provide drawings or technical requirements for design evaluation and cable configuration.
