PIPELINE SYSTEM:

There are 12 pipelines from the storage area to the dock.  Four (4) pipelines are dedicated (i.e., the pipeline goes directly into the storage tank), and eight (8) multiproduct pipelines (i.e., the pipeline ends at a pig station).  From thereon, a hose is connected to the receiving tank pipeline.  Pipelines range in diameter from 4 to 12 inches, and are of varied materials of construction (carbon steel, aluminum, and stainless steel.

  


 

 

DOCK FACILITY:

The dock is leased from the Ports Authority.  The dock accommodates tanker vessels up to 800 ft. in length.  The pier consists of a 10 ft. wide trestle from shore to the main breasting dolphin, two auxiliary breasting dolphins, two mooring dolphins, a walkway, and an outboard dolphin.  The pier simultaneously accommodates two liquid product transfers.  Demaco utilizes the east side of the dock; a neighboring company utilizes the west side.  The main breasting dolphin is a cast-in-place monolithic concrete structure with fendering on both sides.   It is supported by on pipe piles filled with concrete.  The liquid unloading facilities consist of a structure to handle the hoses.  Product and service piping (water and nitrogen) terminate on the main breasting dolphin.  

Harbor:  A 300 ft. wide approach channel 40 ft. in depth was dredged in Guayanilla Bay to the marine facility.  The dredged area increases to 380 ft. wide in the vicinity of the pier.
