Masts & Substructures
Heavy-duty masts and substructure systems engineered for drilling rigs of all sizes.
Heavy-duty masts and substructure systems engineered for drilling rigs of all sizes.
DSL designs and manufactures a variety of mast and substructure configurations — standard cantilever, box-on-box, trailer rig or any other configuration that suits your requirements — with whatever capacity or combination of loadings you need, from 500 through to 3000 HP rigs.
Location most often governs the rig design, so we offer a range of designs to suit yours, be it a fast-moving desert rig, a standard land rig or a winterised rig for extreme cold climates. Rig moving and skidding systems, zero discharge, pipe handling and other features can all be incorporated.
Whether you need a replacement mast and substructure for an existing rig or are building a new one, we can also undertake any interface engineering required for your rig and its equipment.
