Offshore fluid swivels and rotary unions
DSTI’s offshore fluid rotary unions integrate directly into hose reel systems, providing hydraulic, pneumatic, chemical and electrical service for umbilical reel operations. High-pressure (20,000+ PSI) and high-flow designs are available with options for single and multiple fluid passage channels.
Standard stock products are available, in addition to custom solutions engineered to meet the exact requirements for integration into new and existing reel designs.
Subsea fluid swivels, ROV panels and hot stab connectors
DSTI’s subsea swivels are designed for safe and reliable fluid transfer for pipeline / flowline installation and operation applications. Subsea swivels are designed with heavy duty bearings to help absorb moments and loads associated with the installation process. This significantly reduces risk and improves installation time. DSTI also provides high-pressure and high-flow hot stab connectors that are designed to exact programme specifications.
Complete packaged solutions are available, including fluid swivels, ROV panels, hot stabs, bulk head fittings and more.
HPI fluid swivels
DSTI’s offshore high-pressure inline (HPI) fluid swivels allow for 360° rotation of topside and subsea lines. Compact designs offer reduced weight. Heavy-duty internal roller bearings support hose loads and provide a low rotating torque.
DSTI HPI swivels reduce the stress on high-pressure flexible lines, improving efficiency and service life and reducing downtime.
