Derrick Assembly
Expert derrick assembly and installation services with experienced crews available worldwide.

Expert derrick assembly and installation services with experienced crews available worldwide.
DSL rig-building crews erect and outfit derricks all over the world, working for shipyards, derrick manufacturers, drilling contractors, main contractors and operators in any location. Our experience ranges from standard angle-leg derricks to massive double derricks and everything in between.
We can simply provide our expertise to assemble and install the structure, or undertake all other aspects of the installation such as mechanical, electrical and piping. Our approach is to plan carefully in advance — schedules, risk assessments, safety plans, project-specific method statements and quality plans — which helps you integrate derrick erection and outfitting with the rest of the project and plan for both overall safety and production.
