It is reported that by June 1, the berth construction of the CP-300 drilling platform of Liaohe Oilfield Equipment Manufacturing Corporation entered the Helong phase. It is the first self-elevating drilling platform developed and built by Liaohe Oilfield Equipment Manufacturing Corporation. The rig, which is exported to foreign countries, is scheduled to be completed in the first quarter of next year. At present, the design and development of the CP-400 drilling platform is nearing completion, and the basic design will be submitted to the China Classification Society and the American Bureau of Shipping. This indicates that the high-end petroleum equipment in Liaohe Oilfield has been “made” from “manufacturing”.

Liaohe Oilfield Equipment Manufacturing Corporation started the CP-300 drilling platform project in early 2010. From design to construction, it has independent intellectual property rights to fill the technical gap of the domestic jack-up drilling platform. The CP-300 drilling platform can drill at a depth of 91.44 meters with a drilling capacity of 9000 meters.
Before the CP-300 drilling platform was designed and manufactured, domestic manufacturers of drilling platforms purchased drawings for production. Liaohe Oilfield Equipment Corporation aims at the advanced level of international counterparts, keeps a close eye on the frontier of technology, and organizes scientific research personnel to set up projects. In April last year, it passed the review of relevant departments to complete the design of the first self-elevating drilling platform with independent intellectual property rights in China.
It is reported that this company will complete the first domestic self-propelled seat-type wind power installation platform, automatic drilling rig and rack and pinion drilling rig. Among them, the successful development of automated drilling rigs and rack and pinion rigs will change the history of the current drilling needs of thirteen or four employees, and only two or three people can operate.

Agriculture Industry Disinfection

Disinfection efficacy testing is usually done with planktonic cells or more recently, biofilms. While disinfectants are much less effective against biofilms compared to planktonic cells, questions regarding the disinfection tolerance of detached biofilm clusters remain largely unanswered. Burkholderia cepacia and Pseudomonas aeruginosa were grown in chemostats and biofilm tubing reactors, with the tubing reactor serving as a source of detached biofilm clusters. Chlorine dioxide susceptibility was assessed for B. cepacia and P. aeruginosa in these three sample types as monocultures and binary cultures. Similar doses of chlorine dioxide inactivated samples of chemostat and tubing reactor effluent and no statistically significant difference between the log(10) reductions was found. This contrasts with chlorine, shown previously to be generally less effective against detached biofilm particles. Biofilms were more tolerant and required chlorine dioxide doses ten times higher than chemostat and tubing reactor effluent samples. A second species was advantageous in all sample types and resulted in lower log(10) reductions when compared to the single species cultures, suggesting a beneficial interaction of the species.
