1. A remotely controlled twistlock assembly, comprising:
a T-shaped twistlock locking pin;
a twistlock housing within which the T-shaped twistlock locking pin is mounted;
a motion converter mounted within the twistlock housing and connected to the T-shaped twistlock locking pin;
a remotely controlled pin actuator linked to the motion converter in a manner such that extension and retraction of the pin actuator causes rotation of the motion converter and the T-shaped twistlock locking pin;
a latch mounted within the twistlock housing and engageable with the motion converter such that the latch locks the motion converter when the latch is engaged with the motion converter and unlocks the motion converter when the latch is disengaged from the motion converter;
a remotely controlled latch actuator linked to the latch in a manner such that retraction and extension, respectively, of the latch actuator controls engagement and disengagement, respectively, of the latch with the motion converter; and
at least one feedback device mounted within the twistlock housing and positioned to provide remote reporting of a position of at least one of the motion converter and the latch.
