WHAT IS ELECTRIC HEAT TRACING

Protect your process

LNG CONFERENCE MOSCOW, MARCH2017

Electric heat tracing protects

critical processes by

maintaining process

temperatures and providing

freeze protection

PENTAIR

WHAT IF HEAT TRACING FAILS

Protect your process, your installation, and your people

LNG CONFERENCE MOSCOW, MARCH2017

Failure will result in frozen equipment, blocked pipes,

production loss, plant shutdown, structural equipment damage,

repair work, safety issues …

PENTAIR

HEAT TRACING DESIGN REQUIRES AN INTEGRATED APPROACH

Integrated approach for lower Total Cost of Ownership

LNG CONFERENCE MOSCOW, MARCH2017

Complete designed systems, including

heating cables and components,

insulation, control & monitoring,

power infrastructure

Multiple engineering disciplines are

involved: process, mechanical, piping,

electrical, instrumentation

PENTAIR

OTHER TYPES OF TRACING INCLUDE STEAM AND FLUID TRACING

Other types of tracing :

• Steam

• Recirculating Fluid

• Hot Oil

• Glycol

Heat tracing is used to maintain temperature of non-flowing fluids by replacing the heat lost through thermal insulation on pipes, vessels and associated equipment

Pentair provides the appropriate technology for the specific application

HEAT TRACING CHALLENGES FOR LARGE PROJECTS IN ARCTIC CLIMATES

3. Extreme cold temperatures affect materials + personnel. • Select reliable, qualified products

• Designs must consider upset conditions (LNG - cryogenics)

Materials and Designs Must Be Compatible with Demanding Applications

LNG CONFERENCE MOSCOW, MARCH2017

4. Many facilities are unmanned + access to equipment is difficult• Limited time & personnel for field interventions

• Advanced control & central monitoring is key for operational reliability with

minimal site intervention

2. Many stakeholders involved from around the world• Global support from pre-FEED to construction phase

• Local support during start-up and operations

1. Project management & Engineering is complex• Large Engineering capacity + standardized work

• Accurate, fast change management + clear progress reports

HEAT TRACING SOLUTIONS FOR YAMAL LNG2. SINGLE PARTNER WITH GLOBAL REACH & LOCAL PRESENCE

Pentair is a global organization and is used to handle

international projects.

• Engineering in 5 Pentair design centers + St-Petersburg

• Project management with Technip, France

• Installation supervision on Construction Yards, Asia

• Local team for start-up, commissioning, spare parts, Sabetta

• Technical support group in St-Petersburg + Moscow

One reliable partner for complete project and life cycle support

HEAT TRACING SOLUTIONS FOR YAMAL LNG3. SELECT RELIABLE, QUALIFIED PRODUCTS

• Raychem invented self regulating heat tracing + recognized as a global standard

• Large installed base operational in arctic climates in Russia + globally (offshore/onshore)

• Widest range of heat tracing technologies for all LNG applications

• Products that are exposed to cryogenic exposure are tested and qualified at -170°C

• 2000 km+ of Raychem heat tracing cables on Yamal LNG

Products have to withstand LNG cryogenic exposure

LNG CONFERENCE MOSCOW, MARCH2017

HEAT TRACING SOLUTIONS FOR YAMAL LNG 4. SMART CONTROL & MONITORING

• We selected local control systems with central monitoring, providing optimal total cost of ownership + highest operational reliability

• 1200 hazardous area electrical field panels + 35 central control & monitoring panels for full visibility from central location

• Real time monitoring, for pro-active maintenance and reduced site activities (real-time data, alarms, history logging, trending, …)

• Flexible, user-friendly programming and adjustments during commissioning and operations

Operational reliability. Full visibility. Less site interventions.

HEAT TRACING SOLUTIONS FOR YAMAL LNG 4. SMART CONTROL & MONITORING

Unique smart capabilities specifically for this project:

• We developed a remote monitoring device in the field panels, for central monitoring of all electrical circuit breakers on site

• We developed low temperature cut-out limits in our controllers, to switch off heat tracing circuits in case of unforeseen cryogenic LNG exposure, to protect tracing system

Smart control & monitoring = lower risk for installations + less exposure for personnel to arctic conditions

Smart control & monitoring = lower risk for installations and personnel

LNG CONFERENCE MOSCOW, MARCH2017

PENTAIR

When harsh arctic conditions call for unmanned plants,

the use of advanced control & monitoring in electrical

heat tracing systems ensures operational reliability of

your process with minimal need for site activities
