Drilling Rig Derrick
Lee C. Moore's drilling rigs can be found on the job of virtually every major drilling company around the world in a variety of environments, including off shore. These rigs are very large which makes them difficult to handle and transport. Job site material handling is often rough and tumble. The durability of hot-dip galvanizing (HDG) makes it the perfect coating for these conditions without special handling or packaging. Drilling rigs are exposed to and expected to be operational in extreme weather and temperature conditions as well as harsh chemical environments. Fortunately HDG can withstand termperatures ranging from -75 degrees F to 392 degrees F and performs well in a pH range of 4.5 to 12.5. In addition to creating a barrier between steel and the envirnoment, zinc has the ability to cathodically protect the substrate metal, even if the coating is damaged. The excellent field performance of a hot-dip galvanized coating provides the customer with a durable and cost-effective product that requires little or no maintenance, despite the size and complexity of the rig.
The size of these structures makes coating maintenance difficult. The pace at which they are being erected, used and then moved to a new location makes maitenance downtime very expensive. HDG provides a longer life span than any other protection plan with little or no maintenance costs which is critical to a driller's success.
Lee C Moore learned years ago about the value of a durable hot-dip galvanized coating for their rugged derricks. Today their rigs are found around the world, some in operation for over 40 years. Detailed maintenance records have been kept on every rig ever built and as a result, Lee C Moore continues to specify hot-dip galvanizing.
