A regional contractor for St. Croix’s heavy industry
We’re a certified Caribbean contractor that mobilizes crews and equipment to St. Croix when a plant, tank or structure needs work done to standard. The island carries one of the largest industrial footprints in the Leeward Islands.
We bring qualified welders, AWS D1.1 and ASME IX procedures, API 650/653 tank capability and the rigging to lift and set steel, so a St. Croix project gets certified capacity for the scopes that need it.
Built for the refinery, the oil terminal and heavy industry
St. Croix hosts one of the largest refinery and oil-storage complexes in the Caribbean, the former HOVENSA facility now operating as an oil-storage terminal, alongside its ports and industry. That base runs on tank work, piping, structural steel and mechanical maintenance.
That’s exactly our scope: storage tanks under API 650 and 653, pressure equipment and piping under ASME, structural steel under AWS D1.1, and rotating-equipment maintenance during turnarounds.

From enquiry to a documented handover
A clear path that keeps your project on standard and on schedule.
Scope & enquiry
You send the drawings or scope. We review the code, materials and feasibility, and come back with a quote.
Engineering & WPS
We confirm qualified welding procedures (WPS/PQR), verify mill certificates and material traceability, and plan the lift and weld sequence.
Fabrication & welding
Our in-house shop and field crews cut, fit and weld to AWS D1.1, ASME IX and API, with dimensional and heat-input control.
Delivery, install & inspection
We rig, lift and set the work, run visual inspection and NDT (dye penetrant, ultrasonic), and hand over full documentation.
Built to the standards your facility relies on
Industrial work is only as good as the code behind it.
For your procurement team: welder qualifications (WPS/PQR), certificate copies and safety documentation are available on request for vendor approval.
