Preventing Ballast Water Invasive Species Propagation

July 13, 2013

Ballast water is used to stabilize ships at sea, being pumped-in to weigh down a ship for safe navigational conditions when the ships hull is not filled with cargo for a voyage. Controlling the amount of ballast water embarked helps to reduce stress on the hull while providing transverse stability when underway. The correct use of ballast also makes ship propulsion more efficient and increases maneuverability. By correctly controlling the amount and location of ballast within the hull an officer can compensate for weight lost due to fuel and water consumption during a voyage, always maintaining optimum stability. Just by reading the paragraph above it becomes clear to any landlubber that ballast water is vital for safe ship operations.

The Ponta Negra Terminal (TPN) to be built at the south side of Jaconé Beach at Ponta Negra Point is to be one of the biggest ports in the country. DTA Engineering, responsible for the project, unofficially called the Pre-salt port and with an investment forecast of $5,4 billion in an area of 557,2 thousand square meters, is expected to link oil & gas pipelines from the Pre-salt plays to the Petrochemical complex of the state of Rio de Janeiro (Comperj), which is located in the nearby city of Itaborai. The project includes a port, a ship and rig maintenance shipyard and a refinery. Authorities consider the location ideal due to the fact that the point has a natural depth of 30 meters.
