<strong>Deepwater</strong>: Dry Trees vs. Subsea Tieback • Dry trees preferred for accessibility • Dry trees more difficult for flow assurance • Typically cannot depressurize • Short cooldown times (2-8 hours) • Fewer insulation/heating options than subsea • Limited chemical (MeOH/MEG) deliverability • Wax deposition more difficult to remediate
