Barge Loading Arms

Barge Loading Arm Introduction

Barge Loading Arm (BLA) is designed to load/unload petroleum or chemical products to small ships and barges along protected seacoast or river side.

BLA design ensures six degrees of freedom, allowing movement in all directions generated by tide change, wind, current and other environmental conditions.

As the conventional Marine Loading Arm has brought a significant improvement in safety over a hose solution in the transfer operation of product, BLA is the simple solution, instead of hose to serve the small ship and barge with same advantages.

The BLA is composed of rigid articulated piping, self supported, fully balanced and provides an easier, a safer and a more ergonomic solution without need of extra lifting, supporting equipment or tools required with hoses. With the same reliability level of other Technip Energies’ products, BLA offers a long service life with a low cost of ownership to the user.

Barge Loading Arms – Main Equipment

Chiksan® Swivel Joints

  • The core of a Chiksan ® marine arm is the swivel
  • BLA is equipped with 6 Chiksan® swivel
  • Each swivel joint is made up of a male and a female part joined by two or three ball bearing
  • A compression type packing seal is used to seal the two parts of the swivel
  • Replaceable raceways (snap in race) allow easy revamping and consistency of
Chiksan® Swivel Joints

Connection to the ship manifold by a flange or by a manual QCDC coupler

Drain Ports

BLA is equipped with two drain ports located at the lowest points:

  • One near the inlet flange;
  • One near the connection to the ship.

Each drain port can be equipped with cap or a manual flange
