Marine loading arm for ship tanker fluid transfer, internal floating roof

Marine Loading Arm

A Marine Loading Arm is an articulated pipe system for then transfers of liquids or gases. This may be operated manually or
hydraulically.

A marine loading arm comprises several components namely: base riser, inboard arm, outboard arm, balancing assembly, supporting structure, and operating system.
The articulation is assured by swivel arrangements.These arrangements (or styles) allow for complete movement in all planes.

We design and manufacture a wide range of Marine Loading Arms to load and unload almost any liquid and compressed gas product from river barges, ships and ocean going super tankers. Pantograph balanced mechanical link technology provides the stability and strength for this most demanding task.

The design of the marine loading arm / Land loading arm varies from client’s requirements and environment. So the user need to fill the “design datasheet”, which include: terminal tidal range, ship's tonnage, liquid handled, pipeline size, pressure rating, environmental parameters (the wind load, temperature, earthquake loads), etc.
Unless otherwise required by user, the design environment parameters of LYGSVT marine loading arm are as follows:
• Design wind speed: static (stowed) state: ≤55M/S
• Design wind speed: ≤ 16 M/S
• Earthquake resistance coefficient: 0.3 G

Major Models:

At present, the marine loading arms designed and manufactured by our company are of many structural forms: AM61, AM62, AM63, AM64, completely capable of meeting the requirement of domestic and foreign markets.
