Building a
test rig

Test rig for Cameron Sense AS

Wagenborg Foxdrill was delighted to have been selected from seven companies to erect a test rig in Andoya, Kristiansand, Norway on behalf of Cameron sense AS, the drilling & production systems business unit of multinational Cameron. The company designs and produces pressure control equipment - systems to control pressure in a drilling hole – and drilling equipment.

However, Wagenborg Foxdrill was awarded this assignment under the condition that execution had to start within two weeks. This naturally meant that the entire project preparation also had to be realised within two weeks: engineering lifting plans, writing working procedures, QHSE documents, equipment lists and packing equipment containers. Subsequently, everything was transported to Norway after which Wagenborg Foxdrill got the project underway.

During the first days our employees were mainly sorting all the equipment and materials, such as beams, bolts, nuts and plates. Before starting, the project manager decided to split the assembly of the rig into three separate sections. For every section two side panels were assembled horizontally on the ground. Subsequently, three mobile cranes positioned the two panels so they were straight and then the missing beams were installed. All the sections were assembled until the entire rig, measuring 50 m in height, was built.

After the installation of the entire rig in early January, the staircase was built and positioned, and the final terraces and grids were installed. Then all hydraulic ducts, air ducts, cable gutters, including the cables, were mounted.

Finally, an overhead crane was installed at a height of 50 m. This crane will be used to lift so-called smart rackers in and from the test rig. A smart racker is a fully automised drill pipe handling system.

The type signification III and IV indicates for which drill string the pipe handler can be used. A drill string indicated the number of connected drilling jars. A type III is meant for drill strings comprising three drilling jars; a type IV is suitable for drill strings with four drilling jars.

The test rig was delivered to Cameron Sense in February. Nowadays the rig is used to test the smart rackers type III and IV. The rig was built next to an assembly hall in which the smart rackers are produced. After assembly the smart rackers are thoroughly tested in the rig and when the tests are successful, they are transported all over the world to be put into action.
