Cylinder LO trace
heating cable
WinGD specifies the 10QTVR2-CT self-regulating heating cable for engine in-
ternal and external cylinder LO piping. Detailed technical information about this
cable can be found in MIDS.
To reach the required LO temperature of 40 +10/-5°C, the proper length of
heating cable must be selected for the engine and traced along the system side
piping spirally or in parallel, depending on the cable/pipe ratio (see Figure 4-19).
Figure 4-19 Trace heating cable arrangement
Considering the ME power, LO feed rate and environment condition, WinGD
specifies a minimum heating cable length ‘Lc’ as listed in the following table:
Table 4-3 Heating cable specification
Considering the system side cylinder LO pipe length ‘Lp’, the heating cable must
be longer than the lubricating oil pipe, i.e. ‘Lc’ > ‘Lp’.
Insulation of trace heated
cylinder LO pipe
To maintain the desired temperature, the system side cylinder LO pipe must be
well insulated. The following requirements must be considered:
• Insulation material such as mineral wool, glass fibre, or other material of
class approved type can be applied.
• WinGD recommends an insulation thickness of minimum 25mm.
NOTE
On the engine side, electrical trace heating is applied in the rail unit to
keep the cylinder lubricating oil within the required temperature range,
even during gas operation in cold areas.
