Not something that would happen often, but when Airdrill got a call from a Japanese government funded aid project manager involved in a harbor deepening program in Northern Vietnam after only 20% of the required work had been completed on some 18 months, we knew we had to do something special.
The level of local support for any rigs on site was minimal however there were two big diesel powered generating sets on a barge available as a starting point. With a 2-4 meter tide run plus 1-2 meters of swell and the aid of GPS positioning a rig with a fully floating drill head was designed. To achieve the desired production rates the client requested 2 rigs and to reduce time consuming moving of the barge the rigs were mounted onto rails along one side of the barge.
Hurricane have released the next generation of compressor boosters. The 6T-276-41 and 4T-276-41 replace the popular M41's and 636's respectively. Both the 6T-276-41 (1800cfm) and the 4T-276-41 (1400cfm) use a four cylinder single stage booster block. The 6T is powered by a Caterpillar 3208, while the 4T is powered by the John Deere 4045.
US manufacturer, Schramm Inc. and Australian engineering services company, Airdrill have strengthened their relationship by renewing and expanding the Australian Dealership Agreement. The agreement allows Airdrill to continue assembling Schramm drill rigs and manufacture Schramm components under license. The agreement also expands Airdrill's territory to include Australia, Indonesia, Malaysia and New Guinea. The agreement was signed following the successful assembly and commissioning of the Schramm T685WS Rotadrill for McKay Drilling in mid 2003.
West Australian manufacturer Airdrill Ltd has developed an exciting new concept in heat exchangers called 'Airdrill Cooler'. This innovative low cost alternative to existing heat exchange technology, is more robust, easier to maintain, and less complex to manufacture than the existing technology, which is used extensively in the mining and resources sector.
As Peter Hall, Airdrill's Mechanical Engineer explains, "We use heat exchangers in Airdrill's compressor boosters to supply high pressure air for the drilling rigs we make. Basically they work like a car radiator to cool hot air or fluids.
