Industry Applications

Offshore Drilling Platforms

Compact, corrosion-resistant space-saving frames engineered for crude oil cooling on offshore rigs, built to withstand continuous marine spray and high dynamic structural vibrations.

Refinery & Petrochemical Plants

Heavy-duty structural frames handling high-temperature fractional distillation cooling units, ensuring rigid plate containment and zero-bypass fluid integrity under fluctuating thermal loads.

FPSO Vessels

Specially designed skidded frames that absorb sea-state wave motions and structural flexing, maintaining constant compression for top-side process heat exchangers.

LNG Liquefaction & Regasification

Cryogenic-tested structural steel frames optimized for extreme temperature drops during natural gas sub-cooling and liquefaction processing, preventing material embrittlement.

Subsea Sub-Stations

Enclosed, hyperbaric-tested structural frames designed for subsea gas compression and cooling systems, featuring specialized cathodic protection compatibility.

Produced Water Treatment

High-alloy lined frames built to manage aggressive, high-salinity produced water and chemical injection cooling loops without risking structural degradation.

Having Doubts? Our FAQ

Does Frigate design heat exchanger frames to meet custom space constraints on existing offshore platforms?

Yes. Our engineering team specializes in brownfield retrofits, utilizing advanced finite element analysis (FEA) to design high-capacity frames that fit precisely into limited footprints without compromising structural load paths or ASME/API compliance.

What raw materials do you source for highly corrosive oil and gas environments?

We source premium, certified raw materials including heavy carbon steel (SA516 Gr 70), 316L Stainless Steel, Duplex, Super Duplex, and exotic alloys or claddings like Inconel, depending on your project’s sour gas (H2S) or marine salinity exposure levels.

Can these frames accommodate third-party inspections (TPI) before shipping?

Absolutely. We regularly coordinate with international inspection agencies such as Bureau Veritas, DNV, Lloyd’s Register, and TUV. All material test reports (MTRs), welding logs (WPS/PQR), and NDT reports are fully documented for seamless validation.

How does Frigate minimize structural deflection under high thermal cycling?

Our designs feature reinforced tie-rod support plates, thick end-plates, and precision-machined guide bars. This heavy-duty configuration ensures uniform clamping pressure across the entire plate pack, absorbing rapid thermal expansions without risking leaks.

What surface treatment options do you provide for offshore deployment?

We offer heavy-duty protective coating systems compliant with the NORSOK M-501 standard, typically involving a 3-coat zinc-rich epoxy paint regime. Hot-dip galvanizing and customized offshore marine-grade specifications are also available upon request.
