Protecting your assets & minimizing downtime

Fast Turnaround

Repairs and upgrades to existing jackup legs are JSA’s day-to-day business.
Fast turnarounds for jackup leg components such as racks, chords, and
bracings are possible due to our extensive steel inventory and fully integrated
manufacturing capability. Our stock materials carry multiple certifications and
include 100 KSI yield plates in thicknesses of 4”, 5”, 6”, 6 1/2”, and 7” which
can be used on virtually any jackup anywhere in the world.


Through our quality resource mills in South & North America, Europe, and Asia,
we meet your most stringent chemical and mechanical properties with seamless,
SAW, ERW & HFI pipes to various API 5L and plate grades. Our Jackrabbit plant
has the ability to make small diameter welded pipes as per API, ABS, DNV, etc.


We fabricate extra high strength, offshore, shipbuilding/hull, boiler/pressure
vessel and structural steel to various International structural steel standards
such as API 2W/2H, EN 10025, EN 10225, and ASTM.

Cut Shapes

Our state-of-the-art steel and flame cutting facility produces the finest
available steel products for the oil & gas industry, and commercial usage.
Our specialized flame cutting machines with CNC controls are designed to
meet our high standards and installed with precision alignment.


Engineering, Consultancy, Inspection & Welding services are provided through
Jackup Structures Alliance (JSA). Our core business is the supply of critical
structural components for offshore jackup rigs. JSA also has the capabilities to
provide on-site technical services in the builder’s yard to assist with the assembly, erection, and alignment of the legs, guides, and jacking systems. Also included
in our capabilities is the basic design of fixtures for assembling the legs, welding procedures and other fabrication guidelines. In addition, JSA provides general
light and heavy fabrication of other components for rigs with special emphasis
on high-strength steels, such as:

• Jackup gear racks and chords.
