A method of controlling an accumulation in a fluid system and associated apparatus is disclosed. The method comprises heating. The heating is adaptive or adaptable. The method comprises adapting the heating in accordance with a parameter associated with a development of accumulation. The parameter is monitored. An associated subsea heating system () for controlling an accumulation in a subsea flow line () is also disclosed.

Method for hydrate control

A subsea system comprises a multiplicity of subsea installations (M-. . . M-n) and a common transmission line () in an umbilical for the conveyance of power or data communication electrical signals to the subsea installations. The system provides on the common transmission line a plurality of safety signals (T-. . . T-n) in the form of tones separate in frequency from each other and the other signals on the line. Each subsea installation is arranged to receive from the common transmission line selectively a respective one of the safety signals for the control of a fail-safe device () in the installation.
