Offshore and Subsea Applications

In order for fiber-optic rotary joints (FORJs) to perform as intended, it’s essential for all of their optical and mechanical components to be manufactured with utmost precision. Fortunately, there is one company that you can rely on to meet this requirement: SPINNER. To ensure top quality, we apply ultra-high standards every step of the way, from design across sourcing of the materials to state-of-the-art production and meticulous assembly and testing.

SPINNER also supplies both off-the-shelf and customized combinations of fiber-optic and RF rotary joints for offshore and subsea applications. You can count on getting the intelligent, innovative solutions you need for

  • Remotely operated vehicles
  • Winches of all kinds
  • Camera systems across the board
  • Large and small drilling systems

SPINNER Subsea Offshore Key

Regardless of where in the world you are located, you can count on us to support you with topnotch fiber-optic rotary joints and multiplexers, electrical slip rings, rotary joints for media, and hybrid joints for demanding offshore and subsea uses.

One common use of fiber-optic rotary joints is for conveying communication or sensor data through winches. It goes without saying that they have to be extremely robust for these applications. SPINNER builds fiber-optic rotary joints to reliably withstand shocks and vibrations and ensures this with thorough testing. Available with 1, 2, 3-4, 3-8, 7-21, or 21-54 channels and any fiber type (single-mode, multi-mode or thick-core), they transmit signals with negligible return (reflectance) losses.

To maximize the benefits of its FORJs, SPINNER also carries highly compact, outstandingly reliable multiplexers able to convert RS-422, HD-SDI 1.5 Gbit, HDI-SDI 3.0 Gbit, video, Ethernet, GigE and other data protocols.

SPINNER’s portfolio includes a range of special-purpose FORJs for data transmission at high speeds and/or in EMI/EMC-sensitive environments.

Also available from SPINNER are hybrid joints that combine high voltage slip rings with FORJs. Although these systems are mostly used above water, we also offer excellent choices for underwater applications with pressure compensated units.

Slip rings are electromechanical devices for transmitting power and electrical signals between two structures, one of which is stationary while the other rotates. The second of the two can either rotate around its own axis a defined number of times, or else turn by an angle smaller than a complete revolution, for example 60°. It can pass electric current or data while rotating.
