A fluid diverter

A method of monitoring the integrity of a subsea well or a fluid sequestration site, the method comprising:

• i) capturing a volume of fluid being released by the subsea well or the fluid sequestration site, using a fluid control unit;
• ii) directing the volume fluid to a detection unit, using the fluid control unit;
• and
• iii) restricting the flow of the volume of fluid to the detection unit until its flow rate exceeds a threshold value, using the fluid control unit.

An apparatus for monitoring the integrity of a subsea well or a fluid sequestration site, the apparatus comprising a fluid control unit for restricting the flow of a volume of fluid until its flow rate exceeds a threshold value, the fluid control unit comprising:

• a first unit enclosing a first volume and arranged to capture the volume of fluid within the first volume and to provide the volume of fluid to a second volume;
• and
• a second unit at least partially enclosing the first unit and enclosing the second volume and arranged to provide the volume of fluid from the second volume to a third volume;
• wherein:
• the fluid control unit is configured to restrict the passage of the volume of fluid to the third volume until the flow rate of the volume of fluid exceeds a threshold value.

A method of restricting the flow of a volume of fluid until its flow rate exceeds a threshold value as part of a process for monitoring the integrity of a subsea well or a fluid sequestration site, the method comprising:

• providing a first unit and a second unit, the second unit at least partially enclosing the first unit;
• capturing the volume of fluid within a first volume enclosed by the first unit
• providing the volume of fluid to a second volume enclosed by the second unit;
• providing the volume of fluid from the second volume to a third volume;
• and
• restricting the passage of the volume of fluid to the third volume until the flow rate of the volume of fluid exceeds a threshold value.
