Qualified to industry standards (e.g. ISO 12736:2023) that include simulated services tests.

‍

Subsea production flowlines
- Maintaining the temperature of produced fluids as they travel from the well to the host facility
Subsea pipelines and tiebacks
- Particularly long-distance tiebacks where fluids can lose significant heat before reaching the host
Rigid pipelines
- Where B85 can provide additional thermal insulation
Subsea jumpers and spools
- Insulating complex sections around subsea infrastructure
PLETs and PLET connections
- Where insulation may be required around connection points and associated piping
Manifolds and subsea structures
- Particularly where maintaining temperature is important across complex geometries
Deepwater and ultra-deepwater developments
- Where the combination of low ambient seawater temperatures, high pressures and long flow paths creates significant flow assurance challenges
High-temperature subsea developments
- Where conventional insulation systems may not provide sufficient thermal performance.

Extremely durable

ContraTherm® B85 excels in both its insulation and durable mechanical properties, and was developed to meet the needs of today, tomorrow, and beyond.

Unlimited water depth

The future of oil and gas field exploration will take place at greater depths and greater pressures. B85 is solid, and therefore withstands difficult environmental conditions to ensure reliable and consistent flow.

Bespoke, for all geometries

B85 is a pour-in-place solution which meets tight dimensional requirements and is highly adaptable to suit bespoke needs.
