FPSO vessels operate in harsh offshore environments, where space is limited and uptime is non-negotiable. Traditional shell-and-tube exchangers often fall short due to their large footprint and susceptibility to fouling from crude oil, produced water, or seawater. Process engineers need equipment that delivers high heat transfer efficiency while withstanding corrosive fluids and fluctuating pressures. This is where modern FPSO heat exchanger designs, particularly welded plate types, offer a practical solution.
A welded plate heat exchanger uses a series of corrugated metal plates brazed or welded together, creating alternating channels for hot and cold fluids. Unlike gasketed units, the welded construction eliminates elastomer seals, making it ideal for high-temperature and high-pressure duties common in FPSO topside processing. The counter-current flow pattern maximizes temperature cross, achieving approach temperatures as low as 1°C. This design is particularly effective for crude oil heating, produced water cooling, and gas compression interstage cooling.
When selecting an FPSO heat exchanger, engineers should evaluate these standard performance ranges:
These parameters make welded plate exchangers a strong alternative to traditional shell-and-tube units, especially when weight and footprint are critical.
For crude oil heating and produced water cooling, HT-Bloc welded plate heat exchangers offer high thermal efficiency and compactness. In gas processing or amine systems, wide gap welded plate heat exchangers handle viscous or particle-laden fluids without clogging. For seawater cooling loops, gasketed plate heat exchangers with titanium plates provide corrosion resistance and easy maintenance. Each design is compatible with existing Alfa Laval or Compabloc installations, allowing retrofit without major piping changes.

Every FPSO heat exchanger we supply comes with free thermal design and selection service, ensuring you get the right unit for your process conditions without overpaying for oversized equipment.
Yes, wide gap welded plate designs are specifically engineered for fluids with suspended solids or high viscosity. The gap between plates can be increased to 5–15 mm, reducing the risk of blockage while maintaining good heat transfer performance.
Simply provide your process parameters—flow rates, inlet/outlet temperatures, operating pressure, and fluid properties. Our engineers run thermal simulations to select the optimal plate pattern, material, and size, delivering a datasheet within 2–3 business days at no cost.
Yes, many of our gasketed and welded plate designs are dimensionally interchangeable with major brands. We can supply replacement plate packs or complete units that fit existing frames, minimizing downtime during retrofits.
Our manufacturing facility is ISO9001 certified, and we hold ASME U stamp for pressure vessel fabrication. Units can also be supplied with DNV, ABS, or Lloyd’s certification upon request for offshore projects.
For standard welded plate units, lead time is 8–12 weeks from design approval. Custom designs with exotic materials or special coatings may require 14–16 weeks. We offer expedited delivery for urgent maintenance shutdowns.
Welded units require minimal maintenance since there are no gaskets to replace. Periodic chemical cleaning or backflushing is recommended to remove deposits. We provide a detailed maintenance manual with every shipment.

Industrial furnace and boiler exhaust gases carry vast amounts of unutilized thermal energy. The SHPHE custom Plate Air Preheater (PAPH) is target-engineered to intercept this high-temperature flue gas, recovering valuable waste heat and transferring it directly back to incoming combustion air or process gas streams. By substantially elevating the temperature of your flame feed, our custom systems optimize combustion thermodynamics, deliver massive fuel savings, and significantly reduce industrial carbon and emissions footprints. Built to withstand severe flue-gas environments, SHPHE PAPH systems serve as the premier choice for modern, energy-intensive plants prioritizing decarb compliance and maximum thermal efficiency.
The SHPHE Printed Circuit Heat Exchanger (PCHE) represents a paradigm shift in microchannel thermal management, meticulously engineered for the world's most critical and demanding industrial boundaries. Developed to surpass the physical limitations of conventional shell-and-tube designs in ultra-high-pressure environments, our custom PCHEs integrate advanced photochemical etching and solid-state diffusion bonding to provide unmatched safety, thermal efficiency, and integrity under extreme stress. Initially deployed within high-consequence sectors such as aerospace and nuclear power generation, PCHE technology has completely revolutionized high-density thermal processing. Today, SHPHE brings this breakthrough engineering to mainstream energy transitions—including LNG liquefaction, supercritical CO² power cycles, hydrocarbon processing, and high-pressure hydrogen systems—enabling plants to maximize energy recovery, ensure zero-leakage security, and significantly shrink environmental footprints.
Since the invention of the plate heat exchanger (PHE) in 1923, thermal technology has evolved from standard food-grade processing to highly complex industrial operations. At SHPHE, we take this classic, versatile design and transform it into highly bespoke heat transfer solutions tailored to your unique process fluids and thermal loads. While traditional gasketed PHEs offer high efficiency and compact footprints, SHPHE optimizes plate corrugations, metallurgy, and sealing systems to handle your specific chemical, HVAC, or energy recovery parameters. Our custom-engineered gasketed plate heat exchangers provide outstanding scalability and ease of maintenance, serving as an indispensable asset for heavy industries—including oil and gas, metallurgy, and food processing—where uptime, energy recovery, and long-term sustainability are top priorities.

Mike Torres
Lead Process EngineerWe've been using this FPSO heat exchanger on our latest project offshore Brazil, and I have to say, the thermal performance is rock solid even under fluctuating crude flow. Installation was straightforward, and the maintenance access is way better than the old shell-and-tube units we had. Only wish the delivery lead time was a bit shorter.
Sarah Kim
Rotating Equipment TechnicianBeen working with these exchangers for about six months now. They handle the high-viscosity crude without fouling up as fast as I expected. Had a small leak on a gasket last month, but the support team sent a replacement kit overnight. Not perfect, but honestly, it's the most reliable unit on our FPSO deck right now.
Jake Henderson
Senior Project ManagerSpec'd this heat exchanger for a new FPSO conversion project and it passed FAT with zero non-conformances. The compact design saved us about 15% deck space compared to the competitor's bid, and the pressure drop numbers matched the datasheet exactly. My client's inspection team was impressed. Definitely my go-to for future topside modules.
Elena Rossi
Process Safety EngineerI'm usually the one who finds fault during HAZOP reviews, but this exchanger checked all the boxes for relief sizing and material compatibility with sour service. The titanium clad tubesheet feels robust. Only gave it 4 stars because the documentation pack could be more detailed on the thermal cycling limits for start-up scenarios.
