Hydrates, solid crystals looking like compact snow (gas system) or slurry (oil system), are formed of water and gas at high pressure and low temperature (Figure 1) [1]. These conditions are usually encountered during shutdowns and restart operations in deepwater environment.

Considering the associated production shortfalls and the cost of offshore remediation means, line blockage due to hydrates formation must be avoided [2]. And as a consequence, one of the main constraints in the design and operation of deepwater subsea developments has often been the management of hydrates in the production flowlines.
