Specialists in
Tie-in & Subsea Solutions
We transform complex offshore challenges into practical, reliable subsea systems. With expertise spanning concept, engineering, and fabrication, we deliver solutions optimized for performance, cost, and constructability.
H-mode Tie-in system
The H-mode tie-in technology is patented and field-proven subsea tie-in system for 4″–36″ lines, applicable to rigid spools, flexible lines, PLRs, and export lines.
Open Porch
An innovative large-bore tie-in solution for export lines. It eliminates side shifts, manages operational loads, and offers modular configurations like PLET integration to streamline subsea installation.
Subsea Loading System
A qualified offloading solution for shallow fields, enabling direct oil transfer to shuttle tankers. It eliminates the need for permanent export pipelines or FSO/FPSO infrastructure through integrated modules.
Flexible-to-flexible
Connect two flexible lines, then recover the tie-in tool for reuse. Only the connector and hubs remain on the seafloor with the flexible lines.
