Accessory Notes

Vapor Return Line: Normally hard-piped with swivel joints for articulation. Final connection from the end of the arm at the triple swivel to the vessel manifold is via a lightweight hose.
Maintenance Ladders: Safety ladders utilizing an umbilical personnel safety harness that prevents falls. A maintenance platform may also be included at the apex of the arm if required.
Insulation Flanges: SVT utilizes an insulation flange that is integral to the middle horizontal swivel joint in the triple swivel assembly to electrically isolate the ship from the loading arm as required OCIMF standards.
Audio-Visual Alarm Overtravel System: This system uses proximity switches to monitor the maximum reach angles of the arm movements and provide the appropriate alarms; normally a single stage alarm.
Emergency Release Coupler (ERC): This safety system combines a two stage audio-visual alarm that also automatically disconnects the loading arm from the vessel at the triple swivel assembly. SVT uses two ball valves & collar release. Manual disconnection from the control console is also possible. Output signals can be given at the first alarm stage to initiate valve closures and pump shutdowns.
Shut Off Valve at Triple Assembly: Care must be taken when specifying a valve on manual arms as loading arms are normally balanced only in the empty condition. Arms must be completely drained prior to disconnection.
Manual Quick Connect Disconnect Coupler (QCDC): Used in lieu of a flange for the connection to the vessel to save time, the SVT QCDC incorporates a ratchet cam locking design that cannot back off or loosen.
Vacuum Breaker: A ball valve/check valve combination is placed at the Apex of the loading arm to break the vacuum and allow drainage of the arm. Remote control of the vacuum is at ship end of arm.
Nitrogen Purge System: In order to eliminate the use of hoses, purging systems are now located at the riser. The gas rises to the apex and provides a gas cushion which purges both the inner & outer arms.
