AIP honor event was held at HHI’s Seoul workplace
South Korea’s Hyundai Heavy Industries intends to optimize the effectiveness of Very Large Containerships (VLCSs) by streamlining the power system.
HHI and also Korea Shipbuilding & & Offshore Engineering (KSOE) have actually been granted Approval in Principle (AIP) for a brand-new multi-grid power system style system for 15,000-TEU containerships.
The innovation damages down the VLCS power system right into 2 different kinds of power tons: “essential loads,” needed to run the ship. and also “service loads,” required to maintain the intermodal reefers at appropriate temperature levels to name a few points.
For standard container ships, onboard electric tools is usually powered at a reduced voltage degree– 440V or much less. As container ships have actually come to be bigger, nonetheless, the complete quantity of electrical power needed has actually expanded, requiring 6.6 kV or higher-voltage power systems onboard. As an outcome, setup of approximately 8 large-capacity transformers to transform high voltages right into reduced voltages has actually come to be inescapable.
The brand-new HHI technique makes use of multi-grid power systems to decrease the capability of each system, permitting low-voltage power circulation to change the existing high-voltage power circulation. No voltage conversion implies there is no need for the big transformers considering approximately 64 heaps in accumulation that would certainly or else be filled onto the ship, enabling an added loader capability of 60 FEU many thanks to much better room application.
The economic advantage used by the removal of voltage conversion is a cost savings of regarding $320,000 per vessel.
Further, claims HHI, the versatility in the quantity of power provided abreast with the amount of the containerized freight increase the power effectiveness of the ship, getting rid of the unneeded power consumptionof standard power systems.
“With this technology, we have applied for 12 patents at home and have also filed for an overseas patent in the EU, Canada, China and Japan,” stated an authorities of HHIGroup “We will continuously work on the research and development towards better ship efficiency for other types of vessels as well, aiming for enhanced customer satisfaction.”
