Basic Models of Loading Arm

MARINE LOADING ARMS

Basic structure of Loading Arm
Marine loading arm consists of 3 different types of swivel
joints(6 swivels)-Style 50,40 and 80.

The combination of these 3 types of swivel joints allows thearms to follow the movement of vessel in all directions
smoothly and enables safe un/loading operation.

Style 50 swivel joint, located at the top of the riser, permits
horizontal slewing and vertical movement of the arm
assembly.

Style 40 swivel joint, connects inboard and outboard arms at

the apex of the assembly and provides vertical rotation at the
point of junction between in/outboard arms.

Style 80 swivel joint, the termination of the arm assembly,
provides required flexibility around the 3 axis where the arm
connects to the barge or tanker manifolid.

In 2014, we started development of a 6” tubular steelloading arm for liquefied hydrogen in order to realize acarbon-neutral society in the future, and in 2022 we
succeeded in the world's first loading of liquefiedhydrogen.
In the area of liquefied hydrogen (-253 ° C), which is muchcooler than LNG (-162 ° C), existing low-temperaturetechnology alone cannot cope.
We have developed a new structure for the entire LA
including patented swivel joints, patented ERS(Emergency Release System), and pipes, which areconstructed with a vacuum double-wall pipe structure forthe entire wetted pipe, and measures against heat input
and heat transfer for the swivel joints and ERS.

Emergency Release System(ERS) is the systemthat disconnect the loading arm from thetanker manifold within several seconds with noleakage in any emergency circumstances suchas sudden and rapid movement of vessels due
due to unexpected events, such as gust,earthquake, etc...
This ERS system consists of the ERS unit
installed integrally at style 80 swivel joint andthe electrical/hydraulical equipment that
control the ERS unit.
TBG has successful ERS delivery records. fordifferent kinds of fluids and gases and since
the first installation in 1982, all of the LNG
loading arms supplied for LNG export/import inand outside Japan are equipped with this unit.

MARINE LOADING ARMSQCDC is installed at the end of the loading arm and allows fast, safe and accurate
dis/connecting loading arm to the tanker manifold.
By using this quick coupler, it is not necessary to insert a flange gasket or to bolt
the flange to the tanker manifold.
Quick coupler is activated by hydraulic pressure and its flanging time requires
only a few seconds to complete a tight connection.
After connecting coupler to the tanker manifold, the clamp is tightened
mechanically, to assure the correct tightness required for safe un/loading
operation.

Manual Quick Coupler【System outline】
Based on the data from angle sensors installed on the loading arm, PMS
main unit calculates the location of the outer flange of the arm, mooring
position of the ship, drifting speed, or allowable working range, then in
the emergency situation, it alarms for prevention of arm damages.
These data from PMS main unit are sent to the PMS monitor located in
the jetty control room or central monitoring room in the safty area, andthe arm position and the tanker information (location·speed·distance) are
shown on the display.
【Installation advantage】
PMS monitor shows you the position of each loading arm(stored·maneuvering·loading) or arm attitude instantaneously. It also
monitors the mooring position of the ship and drifting speed constantly
and enables you to figure out the safety angles of each arms
quantitatively.
The different kinds of real-time data from the angle sensors and alarming
system for emergency allows you to handle any contingencies inappropriate measures instantly.

(size : 10"~16")(Size: 6"~12")

Manual Quick Coupler is installed at the end of the loading arm enabling an easy
connection by rotating several clamps with the manual handle.
It is unnecessary to insert the gasket or to bolt the flange to the manifold.
The available size is from 6" up to 12" and it can be installed on the existingloading arms.

After-Sales Service
TB Global Technologies Ltd. provides quick and reliable after sales
service worldwide in case of any troubles and needs of repair.
For safe and long-term usage of loading arms, our highly
experienced personnel offer periodical inspection, maintenance andoverhaul with TB-NIIGATA genuine spare parts.
