Subsea thermal insulation


Thermal insulation is an essential component of flow assurance

Improve efficiency and protect against wax and hydrate formation

Why do we insulate?

Maintains

a min temp

during the ’no

touch’ time

Trends in insulation of subsea structures and pipelines


But at the same time

" Easy oil" is starting to run out in certain areas

Drive to explore deeper

Drive toward harsher environments

Deeper oil can be hotter and higher pressure

Developments are more expensive and fields fragmented

Concerns about Wax and Arrival Temperature

hydrates came as a surprise to many......

Flow assurance is a issue and Thermal

Management becomes a issue.

• More complex completions

• More complex hydrocarbons

• Longer tie-ins and tie-backs

• Deeper water

• Artificial lift starts to be used

• Subsea Processing

• Min. Arrival temperature

Longer transfer runs

Hydrate problems

Wax problems

More extensive use of seabed equipment (trees, manifolds, ...)

Heat loss a growing problem as hot oiling can’t be used

Subsea insulation of structures and Pipelines


Insulation of subsea structures


• Subsea processing is proposed – Troll Pilot – and seen to work

• S2B concepts with larger levels of autonomous operation are

developed

• High levels of redundancy are required for stable up-time

• Distances become too large for methanol and MEG inhibition due to

size of regeneration plant

• Active heating concepts in combination with wet Insulation

• Flow assurance becomes the main driver for field design

• In-country content is a requirement for success

• Complexity of structures leads to work being performed at client’s

facility

Insulation of Pipelines


Multiflow Pipelines have been insulated since late 80’s and today there

is a large selection of systems

• Wet insulation• Polypropylene based systems

• Polyurethane based systems

• Rubber based systems

• Pipe In Pipe• Bonded and unbonded

• Active heating• Direct Electrical Heating

• Heat tracing in PIP
