Electrical heat tracing for surface heating on arctic vessels & structures to prevent snow & ice accumulation

The Proposed “IEEE 45.8 Recommended Practice for Electrical Installations on Shipboard - Cable Systems” will reference EHT (Electrical Heat Trace) for heating pipes, tanks, and instrumentation on-board ocean-going vessels. The globally recognized IEEE 515 Standard for resistance heat tracing addresses “traditional” freeze protection and temperature maintenance applications on-board tankers and FPSO (Floating Production, Storage, and Offloading) facilities, but not for keeping un-insulated surfaces above freezing. As fossil fuels are discovered offshore in arctic regions, their development requires increasing resources to prevent the accumulation (or melting) of snow and ice. Outdoor stairs, handrails, walkways, and other exposed and un-insulated surfaces require protection in these harsh environments. These represent growing requirements for EHT to be installed on, in or under surfaces to reduce unsafe conditions during normal operations or during emergency conditions.
