Dry Sump
Units that are installed
on board ships or floating production platforms may require the dry sump
option. This option would be required if the roll and yaw of the ship
would cause the frame lube oil pump to lose suction of the oil in the
sump or any of the running gear to foam the oil from contact with the
oil level. Refer
to Frame Tilt Limits for Offshore
for allowable
tilt with a wet sump in offshore applications.
If the dry sump is selected, both
frame ends are supplied with drains and an additional oil pump chain oiler
is provided. An
oil sump strainer is provided by Ariel to be placed in the pump suction
line at the outlet of the Packager's wet sump.
The packager is responsible to
provide a lube oil reservoir sized and located such that the oil pump
will have suction regardless of the tilt of the ship or floating platform.
