The disclosure provides a system and method for locking and unlocking an extendable column to a deck. A deck-to-column connection assembly includes a pawl and shim used in a sequential de-ballasting and ballasting of the column to the deck that can easily lock and unlock the column with the deck. Generally, the locking method includes ballasting the column to insert a pawl between the column and the deck, de-ballasting the column to raise the column relative to the deck and create a vertical gap between the column and the deck, inserting a shim to fill the gap and secure the pawl in a deployed position, and further de-ballasting the column to raise the deck connected to the column. Generally, the unlocking method lowering the deck to float on water, de-ballasting the column to remove compressive stress on the shim, removing the shim, ballasting the column, and retracting the pawl.
