HX-201 is a shell-and-tube heat exchanger manufactured by Wärmetechnik Boll, commissioned in 1998
and installed on the Hall 2 process line at the Aldervik yard.[^s1]

On 12 June 2026 HX-201 developed a tube leak on the shell side and was taken out of service.[^s2]
The machine register still listed HX-201 as in service at that point; the June 2026 service
report records the entry as needing correction to out of service.[^s3] Process cooling runs on the
plate heat exchanger [HX-210](../registries/machine-registry-aldervik-yard.md) alone until
HX-201's tube bundle is replaced; HX-210 has the capacity for this at summer load, but not at full
winter load.[^s4]

## Change Log

- 2026-06-12: taken out of service after a shell-side tube leak; the machine register's "in
  service" status is superseded and corrected here.[^s2][^s3]

## Open Points

### Tube bundle replacement
id: op-tube-bundle-replacement
- 2026-06-17: replacement tube bundle for HX-201 ordered, targeted for July 2026.[^s5]
