Dewatering

Dewatering

Effective dewatering is a critical part of any commissioning operation after hydrotesting has been completed and is often done during the lifetime of pre-existing pipework. Typically, this is achieved with conventional mechanical pigs either set up in temporary subsea launchers or performed from a platform or FPSO. In such cases the pigs used require full PLR facilities so the pig must be recovered and this can add significant cost to an operations.

Further to this, the bore of the pipeline can vary along its length if it is an older pipeline which makes the line unpiggable by conventional means.

SANCCUS SOLUTIONS

Sanccus provide a selection of solid but flexible gel pig options which do not require PLR facilities as the gel pigs can be preinstalled during laydown and flushed to the environment through any size of port. These pigs are highly flexible so can be used on otherwise unpiggable pipelines.

Our CEFAS approved pigs can be ejected to the sea but can also be chemically broken down if required.

PRODUCT INFORMATION

Pipelines Range
Pipelines Range

Gel technology is very versatile and can be applied anytime during the lifetime of a field from helping to remove hydrotest fluids when commissioning to the bulk removal of hydrocarbons and solids prior to maintenance or when preparing a pipeline for responsible decommissioning.

M-Gel Pig
M-Gel Pig

M-Gel Pig is a highly flexible gel pig with shape memory used in situations where a mechanical pig cannot be applied. It is capable of extruding through chokes and restrictions up to 50% of its diameter and returning undamaged to its original size and shape once through.

Hyper Gel Pig
Hyper Gel Pig

Hyper Gel Pig is a highly flexible gel pig with shape memory which is specifically designed for use in environments of extreme temperature. This means that Hyper Gel Pig can be applied under extreme pipe conditions and can also be stored in very hot or very cold climates without damage.

Atlas Pig
Atlas Pig

Atlas Pig is a highly flexible gel pig with shape memory used in situations where a mechanical pig cannot be applied. It is also capable of withstanding pressures up to 600 barg for up to 72 hours. This allows Atlas Pig to be installed during pre-commissioning.

Mono Gel Pig
Mono Gel Pig

Mono Gel Pig is a pipeline pig made from a mixture of gelled monoethylene glycol and water. Having a melting point of around 30°C it is typically used in colder climates and as with all gel pigs it is used in situations where a mechanical pig cannot be.

Hydro Gel Pig
Hydro Gel Pig

Hydro Gel Pig is a pipeline pig made from a mixture of gelatine and water. Having a melting point of around 25°C it is typically used in colder climates and as with all gel pigs it is used in situations where a mechanical pig cannot be.
