Tie-in & Subsea Solutions
Nautilus Subsea designs, engineers, and delivers robust subsea structures tailored to each field. From concept to installation, we combine technical expertise with practical fabrication experience to create reliable, cost-efficient solutions built for tough offshore conditions.
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.
About Us
Nautilus Subsea is a product-focused engineering company with a strong emphasis on subsea tie-in systems. We combine engineering expertise with practical product development experience, supporting clients with robust and field-proven subsea solutions.
Our team has comprehensive experience across all key project phases, from concept development and FEED studies through detailed design and engineering, to fabrication follow-up and offshore installation and supervision. This end-to-end involvement ensures designs that are not only technically sound, but also practical and efficient to execute offshore.
We have worked on both greenfield and brownfield developments, including the design and delivery of infield structures and tools for inspection, maintenance, and repair (IMR). Our hands-on approach and deep understanding of subsea operations allow us to develop tie-in solutions that reduce risk and simplify offshore execution.
