Pier 54, Telescopic Pile Stubbing

November , 2015

Global Diving & Salvage, Inc. was contracted to provide diving services to assist with removal and replacement of Teredo worm damaged piling under Pier 54 along the Seattle waterfront. Damaged piling were cut off at or below mudline and replaced with new telescopic pile stubs. The galvanized pile stub is made up of an inner and outer section. The stub was maneuvered into position using floats, the base was lowered to the divers who slid it over the exposed, prepared, pile and secured it in place. The telescopic stub (inner section) was secured to the underside of the pile cap. The inner and outer sleeves were then welded together. In total, approximately 45 piles were repaired / replaced.
