Summary of the Project

Unique Group’s Buoyancy & Ballast division completed a 1500-tonne load test on a barge-mounted crane using Water Weights bags.

Client Requirement

The client approached us with a requirement to perform proof load testing for a heavy lift crane on the BG Fenix a heavy-lift cargo barge working in the Gulf of Mexico. The main and the auxiliary hoists required testing to 1500 ton and 400 ton respectively using Water Weights bags.

Challenges faced

  • The Fenix barge vessel was docked on the Pentepec River in the state of Veracruz, hence logistics was a challenge owing to the remoteness of the location.
  • In order to achieve the load test weights, Unique Group had to custom design the spreader beam arrangement in cooperation with one of its vendors and adapt the rigging on the Water Weights.
  • To perform the required load test, 40 Water Weights bags had to be packed and mobilised to the project location.

Unique Solution we delivered

Unique Group’s Water Weights team provided a complete turnkey solution inclusive of expert technical support along with lift design and planning.

The entire load was achieved using a bespoke 4 beam spreader arrangement and combination of 40 Water Weights bags of 55-tonne and 35-tonne capacities.

The bags were rigged to the main and auxiliary hoists only once to achieve a wide variety of capacities for load application at various stages during the test. Throughout the project, the filling and emptying of the water in the bags was controlled through the supplied manifold and valve systems.
