Jacinto Port docks, Houston Texas

Dock retrofits at JacintoPort Enterprise facility

Deepwater was contracted to design and install a cathodic protection (CP) retrofit of the existing dock structures, dolphins and bulkheads associated with Enterprise’s Morgans Point assets, Dock 1A assets and the Enterprise bulkhead for Dock 6/7 at the Houston ship channel's JacintoPort Enterprise facility.

The waterside retrofit sacrificial solution at Morgan’s Point was based on the exposed surface area of the structure and the physical space available for the installation of the retrofit anodes. The primary goal of the cathodic protection system is to provide a low-maintenance system for a design life of 20 years. The Morgan’s Point assets consist of multiple dock structures and two separate bulkhead sections. A total of 111 anodes, each weighing 285 lbs and 14 more 540 lb anodes were installed on docks, bulkheads and firewater piles.

Deepwater designed and installed a cathodic protection (CP) retrofit of the existing dock structures, dolphins and bulkheads associated with Dock 1A assets where a total of 64 anodes, each weighing 285 lbs, and 9 more 540 lb anodes were installed on docks, bulkheads and dolphins at Dock 1A.

The previous ICCP system for Dock 6/7 consisted of 3 anode sleds routed back to an existing TR rated at 100 A. The anode sleds had become non-functional and replacement with ICCP anodes was required. Deepwater’s ICCP retrofit consists of 3 bulkhead-mounted anodes at near-even spacings in the areas with sufficient depth to accommodate the anodes, and utilizes the existing rectifier that has an output of 100 A. The three bulkhead-mounted anodes were designed to accommodate this current demand with a design output of 35 A each. Potential readings for Dock 6/7 were –660 mV pre-installation and –1097 mV post-installation.
