marine terminal is equipped with an emergency electricity generator, piping, and a warehouse to
store towropes, firefighting equipment, and spill control and response equipment. Smaller boats
and tugboats, used to transport tankers in and out of the main platform, use the fluvial piers
located to the south at the land end of the terminal. Halfway along the pier to the south is the
main LPG and diesel loading and unloading platform. This platform, a medium-draft pier, is
designed for ships with a maximum draft of 7 m, whereas the fluvial or low-draft piers allow
vessels with a maximum draft of 4 m.
The site operates in four 8-hour shifts, which considers three working shifts and one resting.
Maintenance areas operate in two work shifts and one administration shift, Monday through
Friday. All other shifts are seven days per week.
The site generates its own electricity at the onsite generation plant. For backup supply, the site
is connected to the electrical grid. The onsite generation is steam generated by 70% natural gas
and 30% refinery gas or sweet gas. Compressed air is generated internally at a compressor
plant. The site receives natural gas from the Ecopetrol facility, which is transported by
PROMIGAS to the site. The generation system is set up with dual burners, so either fuel oil or
natural gas can be burned in the boilers.
Water is supplied by Agua de Cartagena (ACUACAR), and usage is approximately
2,300 gal/min (0.146 m 3 /sec). The intake for this supply is the Magdalena River through Canal
del Dique. Drinking water for onsite operations is supplied by a third-party company. Water is
stored in tanks and is treated by various processes according to its final use. Water to be used
for the fire extinguishing network is stored in tanks untreated and also in ponds on the southern
part of the property. Industrial and sanitary water is clarified with addition of flocculants and
chlorine. Cooling water is further treated through a demineralization process to remove
hardness. This process includes the following phases: clarification, filtration with sand and
activated carbon, demineralization, and aeration. The water supply is supplemented by an
intake from the ocean amounting to approximately 20,000 gal/minute (1.21 m 3 /sec) of cooling
water, which is subsequently chlorinated and discharged back to the sea. This water is also used
to dilute the skim-pond effluents. Wastewater from the office areas is discharged to the septictank
system, consisting of approximately 35 septic tanks. The remaining wastewater from the
