6-core ROV tether floating cable with sleeve net and connector. Foamed PUR buoyant cable with protective sleeve net assembly for ROV tether protection and connection.
The 6-core floating ROV tether with sleeve net is a complete assembly comprising the foamed buoyant cable, a braided protective sleeve net (to protect the cable from mechanical damage and UV exposure at the surface), and pre-fitted connectors (pressure-tested to specified depth). The sleeve net -- typically a polyester braid in high-visibility colour -- provides additional tensile strength, abrasion resistance, and visual identification without significantly increasing cable weight or drag. The foamed polyurethane (PUR) jacket uses a micro-cellular expanded jacket compound with a bulk density lower than seawater (~1.025 g/cm³), giving the cable near-zero or positive net buoyancy. This eliminates tether sag and reduces drag force on the ROV, improving vehicle manoeuvrability and reducing tether management workload during subsea operations.

The jacket is manufactured from a micro-cellular expanded (foamed) polyurethane compound. During extrusion, a controlled foaming agent creates millions of tiny closed-cell air pockets within the jacket wall. These air cells reduce the bulk density of the jacket below that of seawater (~1.025 g/cm³), producing positive or neutral net buoyancy. The jacket retains all the abrasion resistance, oil resistance, and flexibility of standard PUR while achieving the buoyancy needed for ROV tether applications.
Common pre-fitted options include: waterproof aviation-style plugs (IP68, 6-pin), SubConn-compatible wet-mate circular connectors, ROV-specific locking connectors (e.g., MCIL/MCBH), and custom-specified types. All are pressure-tested to the specified depth before dispatch. Specify the connector interface at both tether ends when ordering.
