Description
Summary:
1. Articulate
freely during the transfer, to follow the normal movements of
moored vessels.
2. Can
be equipped with a range monitoring system to provide visual and
audible alarms prior to the ships manifold moving outside the
normal working envelope.
3. Can
be manoeuvred manually, electro-hydraulically depending on loading
arm size, type and duty.
4. Pipe
material: carbon steel, stainless steel, PTFE-Lined
5. Norminal
Diameter: DN***-DN**0(4”**4”)
6. Design
Pressure: *0.*6MPa~**0.0MPa.
7. Design
Temperature:
***6℃~***0℃
Basic characteristics:
Easy operation, easy seal seal change，separate support
structure, the diameter of swivel joints and pipeline is
identical, all swivel joints are identical, namely the spare parts
being required rarely, long reach capability. The loading arm
features a separate support structure with its own generously sized
mechanical bearings, which can take up all major external load and
moment. The swivel joints and pipeline only are subjected to stress
by internal pressure and weight. Pipeline is attached to support
structure by means of special mount which can also compensate for
thermal expansion due temperature variation to avoid overstressing.
Counterweight balancing system makes the loading arm balance in all
positions, balancing inboard and outboard arm by a moving
counterweight. The loading arm has been designed specially to meet
the increased requirements of loading critical media and long reach
capability. The loading arm can be equipped with three hydraulic
driving assemblies for independent movements of the inboard arm,
outboard arm and the slewing movements around its vertical axis.
The driving assemblies are interchangeable, the three cylinders are
operated by an electro/hydraulic control console with stationary
push button panel. A portable removed control system can also be
installed permitting the operator to control the arm movements from
other points of the jetty or from tanker’s deck.. The loading arm
can be equipped with double ball valve or double disk
valve/emergency release coupling which are automatically actuated
when the tanker manifold flange to which the loading arm is
connected moves outside the predetermined working and safely
envelope. The loading arm can also be equipped with QC/DC, it need
not to connect the converging tube between the loading arm and
different manifold flange of the vessel. In this case, the
operation is very convenient and quick. Besides, the loading arm
can be equipped with a vapour return line in 3”, 4” or 6” (large
sizes on request).
