Shell-and-Tube Cooler
medium
17 / 17 models (Inspector)
A shell-and-tube cooler passes cooling water through a tube bundle inside a shell while oil or jacket water flows around it, trading the compactness of a plate cooler for tubes that can be mechanically cleaned and individually plugged without stopping the plant.

What sets a shell-and-tube cooler apart
Inside the shell, a bundle of straight or U-tubes carries one fluid, usually sea water or low-temperature fresh water, while the second fluid, jacket water, lubricating oil or charge air, flows through the shell around the outside of the tubes, redirected back and forth by baffles to improve contact time. Compared with a plate heat exchanger, a shell-and-tube design gives up compactness and thermal efficiency per square metre, but it tolerates dirtier, more corrosive water, handles higher pressure differentials without gasket concerns, and lets a single leaking tube be plugged and left out of service rather than forcing a full plate-pack strip-down.
Main components
Shell
The outer pressure-containing cylinder, usually carbon steel with a corrosion allowance or a cladding on the water side.
Tube bundle
Copper-nickel tubes, 90/10 or 70/30 CuNi, are standard where raw sea water is the coolant, chosen for resistance to biofouling and erosion-corrosion; titanium tubes appear on high-duty or aggressive-water applications. Tube walls run roughly 0.7-1.2 mm.
Tube sheets
Thick plates at each end that the tubes are expanded or welded into, separating the shell side from the water boxes.
Baffles
Segmental plates spaced along the bundle that force the shell-side fluid into a zig-zag path, raising turbulence and heat transfer at the cost of pressure drop.
Water boxes and end covers
Removable covers at each end that let the tube bundle be pulled for cleaning or replacement without disturbing the shell-side piping.
Selection and sizing
Sizing runs on heat duty in kW, the temperature approach between the two fluids, allowable pressure drop on each side, and a fouling factor assumed for the water quality expected in service. Sea water coolers are usually oversized against a clean-tube calculation specifically to absorb the fouling that will accumulate between cleanings. Tube material, number of passes and bundle length are the practical trade-offs weighed against available engine room space and the vessel's typical trading water quality.
Regulations and class
Shell-and-tube coolers in essential cooling services fall under class society rules for machinery piping systems, which set minimum design pressure, material approval and testing requirements, typically a hydrostatic test at 1.5 times design pressure. Where the cooler sits in a fuel oil or lubricating oil circuit near hot surfaces, SOLAS II-2 insulation and leakage-containment requirements apply to the surrounding installation rather than to the cooler itself. There is no fixed statutory survey interval specific to the cooler; it is covered under the periodic survey of the cooling water and lubricating oil systems in the vessel's class survey scheme.
Typical faults
| Fault | Cause | Consequence |
|---|---|---|
| Tube fouling | Marine growth, silt or scale on the water side | Falling heat transfer, rising jacket water or LO temperature over weeks |
| Tube erosion | Sea water velocity too high, or sand and grit ingestion | Wall thinning, eventual pinhole leak and cross-contamination |
| Galvanic corrosion | Mismatched tube and tube sheet materials, or exhausted sacrificial anodes | Localised pitting, tube failure well before nominal service life |
| Tube-to-tube-sheet leak | Expansion fatigue or poor original rolling | Sea water into the oil or fresh water side, contaminating the lubricant |
| Water box gasket failure | Age and thermal cycling | External leak, loss of cooling water inventory |
What to look for in a supplier
- Class-approved design with certified hydrostatic test records for both shell and tube sides.
- Tube material recommendation matched to the vessel's actual trading area water quality, not a generic default.
- Availability of replacement tube bundles or individual tubes sized to the existing tube sheet pattern, so a repair does not require a whole new cooler.
- Anode fitment and access for renewal without pulling the full bundle.
Pull and inspect the tube bundle at the interval the water quality earns, not the interval on the maintenance sheet - a cooler running clean, filtered fresh water fouls far slower than one on raw estuary sea water.

Common Failures & Inspection Points
- Area: Gasket wear and embrittlementCheck: Inspect seals visually for cracks, hardening, swelling and discoloration; verify material compatibility with process fluids; check ClipGrip™ fastening. Aging symptoms and loss of elasticity are replacement indicators.
- Area: Clamping dimension and tightness (Tightening Dimension A)Check: Verify A-dimension per manufacturer specifications with caliper (metallic contact required). Keep bolts clean and lubricated. Avoid over-tightening. Perform regular re-tightening after operating hours. At too low A-dimension, pressure loss and leakage are to be expected.
- Area: Fouling and scale formation on plate surfacesCheck: Monitor pressure differential across heat exchanger (increase indicates deposits). Check heat duty versus design value. Optimize CIP intervals after performance audits. Deposits generate higher pump load (energy waste up to 8,000 kWh/year possible).
- Area: Plate corrosion and cracks / breakthroughsCheck: After disassembly, inspect plate surfaces for local measurements (pitting), cracks and perforation corrosion. Verify material compatibility with process fluid. Observe fatigue cracks especially at corners and transitions. When perforation occurs, plate is unrecoverable and must be replaced.
- Area: Pressure test and tightness inspectionCheck: After disassembly and cleaning, perform hydrostatic test per data sheet. Test pressure typically 1.5× operating pressure. Check external and internal leakage at all connections and plate edges. Document findings.
- Area: Plate sequence and alignment (5-point alignment)Check: After opening, verify plate sequence and honeycomb pattern (corrected chevron patterns must alternate). Activate/validate 5-point alignment system for larger units. Offset or misplacement leads to short-circuiting and reduced heat duty.
