Freeport Harbour Expansion Freeport, Grand Bahama Island
Since 2010 Arc Surveying & Mapping, Inc. (Arc) has provided Freeport Harbour Company (FHC)
with topographic and hydrographic surveying services in support of FHC port expansion
projects. Freeport Harbour is located approximately 50 miles east of West Palm Beach Florida
and is a trans-shipment facility, accepting the largest container ships in the world. The entrance
channel and container berths are approximately 65 feet deep.
Safety and coordination with the Harbour Master, pilots, contractors and vessel operations is
essential in Freeport due to constant berthing and traffic. An open berth is surveyed as soon as
available and topographic surveys are performed during times convenient to container
movement. In addition to topographic construction layout and as-built surveys, Arc has
performed all hydrographic surveys for the port including pre and post dredge surveys.
In 2014 Arc performed a bathymetric and shoreline survey of the entire harbour, adhering to
British Admiralty Charting Standards, for upgrading navigational charting and construction
purposes. A fully equipped Arc survey vessel was transported to the island via ferry from West
Palm Beach, Florida. Within 24 hours the survey vessel was offloaded, calibrated and ready to
work utilizing a Reson 7101 multibeam swath sounder, a Riegl VZ 400 terrestrial laser scanner,
an Applanix POS/MV and an RTK system for tidal measurements. Hysweep was used for
equipment configuration, data collection and processing. Horizontal datum for Freeport is
NAD83 UTM Zone 17 N. Vertical datum is MLW meters.
Freeport Harbour is a unique operation as the expansion is never ending. Bahama Rock
Company drills, blasts and excavates the expansion areas utilizing mine-type draglines, shipping
the road base quality material to the U.S. mainland. As a result of dragline excavation, the
slopes in expansion areas are extremely irregular. In order to develop construction plans for
container berth expansion, FHC contracted with Arc to survey the entire harbour including the
seafloor and shoreline with close detail to slopes. The object of the detailed multibeam slope
survey was to develop a plan to drive corrugated sheeting along the irregular slope and to grout
between the sheeting and cavity prone slope, thereby stabilizing future berths.
