DSL has designed a unique new range of API rated drilling masts for 250 – 500,000lb hook load capacity carrier, trailer workover and drilling rigs.

The masts have been designed to be fully interchangeable with a wide range of existing rigs to provide drilling contractors with a simple solution in the event that one of their masts gets damaged or otherwise put out of service.

A 400-500,000lb capacity mast is now nearing completion and this, along with the 250-350,000lb capacity hook load will be held in stock to enable a fast response to customer requirements;

The masts are designed and manufactured in accordance to API 4F 4th Edition and come complete with complete certification package and monogrammed name plate.

DSL Engineering has taken the opportunity to implement weight reductions where possible, for instance, the 500,000lb capacity mast can also be used for a 400,000 lb capacity application thus avoiding modification to existing raising and scoping cylinders.

DSL is an API 4F & 8C licenced Drilling Structures manufacturer.

We also support drilling contractors & operators with a range of support services including rig upgrades, refurbishment, inspection and recertification from its Worldwide locations including Dubai, Singapore, UK, India and Indonesia.
