The DHL Balloon, in Singapore, was the world's second largest tethered helium balloon.[1] It was inflated in 2006, and closed and dismantled in October 2008.
History
The DHL Balloon was first located on Tan Quee Lan Street in the Downtown Core of Singapore, near the New 7th Storey Hotel and Bugis MRT station.[1][2] Launched at a cost of $2.5 million, the DHL Balloon was a joint venture by Aerophile Balloon Singapore Pte Ltd and Vertical Adventure Pte Ltd, and took one year to plan.[1] The project was sponsored by global courier, freight and logistics company DHL Express which received exclusive advertising space on the balloon.
The business partners involved in the project worked with the Urban Redevelopment Authority (URA), Singapore Land Authority and Singapore Tourism Board to allow public advertising on the balloon, and arranged to lease the site at a cost of more than S$1 million over two years. Prior to this project, large advertisements in public areas were not allowed in Singapore.[3] S$800,000 was spent priming the ground for the balloon and another S$60,000 to purchase the helium.[4]
On 19 April 2006, 40 crew members took 12 hours to inflate the French-made balloon, which took its first passengers in May 2006. The DHL Balloon was operated by Singapore Ducktours, a company which also offers city tours on its amphibious vehicles.[1] By September 2007, more than 150,000 people had ridden on the balloon, 70% of whom were tourists. Up to 1,000 people rode the balloon each weekend and its usage was the highest among all of Aerophile's balloons.
The DHL Balloon's lease on its site on Tan Quee Lan Street expired in August 2008[5] and URA terminated the lease as the site was to be used for the new Downtown line's Bugis MRT station. Singapore Ducktours considered three alternative sites: Beach Road near Park View Hotel, Clarke Quay near Novotel Clarke Quay Hotel, and Gardens by the Bay at Marina Bay but was told by the authorities that these sites were unavailable. Other plans included relocating the balloon to Kuala Lumpur or Johor Bahru in Malaysia. Terminating the venture would cost the company S$1.2 million.[4]
Unable to find a suitable site at which to continue operations, Singapore Ducktours dismantled the DHL Balloon in October 2008.[6]
Ride
Passengers could ride the DHL Balloon and have a view of Singapore's Central Area, including the central business district, Suntec City, Marina Bay, Orchard Road and Little India, and could see Indonesia and Malaysia.[2] Standard flights to Script error: No such module "convert". typically lasted between seven and ten minutes and higher level flights to Script error: No such module "convert". lasted up to 13 minutes.
Features and specifications
The DHL Balloon measured Script error: No such module "convert". in diameter and was filled with 6,500 cubic metres (8500 cu. yd.) of helium. It was certified as an aircraft.[2] It was one of only fifteen similar balloons around the world in cities including Paris and Hong Kong made by Aerophile.
As the balloon was anchored to the ground with a metal cable, it was only able to ascend and descend vertically. It was approved by the Civil Aviation Authority of Singapore to ascend to a maximum altitude of Script error: No such module "convert"., or around 48 stories. Flights to either Script error: No such module "convert". were offered. It could accommodate a maximum of 29 passengers in its gondola.
Piloting
The balloon, which flew between two and six times an hour, was operated by a pilot within the gondola. A hydro-electric winch system controlled take-off and landing.[1] As a safety measure, the balloon was not flown when there was lightning, rain, or when the wind speed exceeded five knots on the ground as measured by an anemometer.[7]
Maintenance
A crew of six pilots worked in rotation with one on duty at any one time. They conducted routine checks daily, weekly and every three months on the balloon and its equipment. The helium was replenished every four to six months and engineers visited the balloon each year to conduct an inspection.[7]
