Offshore Oil & Gas Solutions Moon Pool
Drape Hoses
DSTI's comprehensive line of High Pressure Inline (HPI) hose swivels for offshore moon pools, MPD systems and DAT systems.
DSTI focuses exclusively on fluid swivels and sealing technology for the world's most challenging and critical applications.
Trusted by leading oil and gas equipment manufacturers, operators and contractors, DSTI's HPI swivels maximize uptime while lowering operating costs by increasing the service life of drape hoses on vessels with dynamic positioning systems. This is done by eliminating the added stress and torsional loads the hoses are subjected to while operating in rough seas.
DSTI's moon pool swivels feature a redundant sealing system, inspection ports for identifying early warning signs of servicing needed, an internal locking mechanism for improved safety, and low-torque rotation at maximum working pressure. Additionally, every swivel shipment includes an IADC standard manufacturing record book (MRB) and an operation, maintenance and repair manual.
DSTI’s HPI product portfolio consists of 15 standard designs that allows our clients the ability to standardize their entire fleet of vessels with DSTI’s moon pool hose swivels. If none of the standard HPI configurations suit your needs, contact a member of our team to discuss customized options featuring the same, field-proven sealing technology and design benefits.
