TLS news & blogs

A MUD logging unit is installed on the rig when geologic information must be retrieved on a timely basis. If the formations drilled are not well known or if a specific geologic horizon is targeted, mineralogical data from cuttings brought to the surface with the mud might be essential. MUD logging units can discover and evaluate oil & gas reservoirs rapidly, provide complete drilling parameters and monitor toxic gases, thus ensuring drilling safety, enhancing drilling efficiency and reducing operation cost.
As mud logging units are normally located in the hazardous zone 1 or zone 2, where fire or explosion hazards may exist, and the all the measurement equipment installed inside the mud logging units are not explosion proof, therefore the mud logging units should be positively pressurized by blowing fresh air without flammable gases, which creates a safe working environment not only for electric equipment inside, but also for mud loggers and working personnel.
Our explosion proof and intelligent pressurized containers are designed to meet the requirement of clients, suitable for onshore or offshore drilling, A0 or A60 fire rated. Intelligent pressurized containers are equipped with CPFG (combined pressurization, fire and gas control panels), gas detectors, pressurization fan, fire dampers, etc, which is suitable to be used as mud logging cabin.
TLS provides intelligent pressurized containers to global clients for many years. The pressurized container dimension and specifications can be customized according to client’s requirement.

Our range of Ex d combined pressurisation fire & gas (CPFG) systems are PLC based. When used in conjunction with other products, such as gas detectors, smoke detectors, pressure switches, flow switches and pressurization fans, etc, a complete intelligent pressurisation control system can be constructed, which monitors the conditions of pressurised cabins in hazardous areas.

The tertiary recovery has become the dominant technique for the stable production of old oilfields in the Shengli Oilfield. The cumulatively incremental oil was up to 11.50 million tons by the end of Mar/2006. Chemical flooding has developed from single polymer flooding to multiple compo und flooding systems in the oilfield, and a complete set of chemical flooding with the oilfield's characteristics was formed. The tertiary recovery is facing some major problems, such as inadequate high-quality resources of the polymer flooding, replacement difficulty and unbalanced development of the tertiary recovery technology, and great resulted differences among the chemical-flooding implemented units , etc. The chemical flooding technology and the ability to innovate new products should be strengthened. The developmental space of tertiary recovery should be widened through continuously extending technical storage. The polymer-injection project should be well managed so as to enhance the effect of water decreasing and oil increasing. The intensive pilot study will make the tertiary recovery technology replacement faster.
TLS is honored to work as a partner of the subcontractor involving the Shengli oilfield project. The pressurised MCC shelters manufactured by TLS are used in the oilfield.

A motor control center (MCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter, fuses or circuit breaker, and power disconnect.  A motor control center can also include push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. It may be combined with the electrical service entrance for the building.
MCC's are typically found in large commercial or industrial buildings where there are many electric motors that need to be controlled from a central location, such as a mechanical room or electrical room.
A motor control center panel (MCC Panel) is an assembly of one or more enclosed sections having a common power bus and principally containing motor control units. As those electric elements inside MCC panels are not EX approved, In some conditions, such as hazardous zones in FPSO, MCC panels have to be put in pressurised enclosure / containers for safely work. Pressurised containers are composed of CPFG, fire & gas detectors, pressurised blower fan, pressure difference gauge, control panels, etc. which will create a positive pressure working environment inside for the MCC panels by blowing fresh air when the MCC panels are installed inside. TLS offshore containers international is a professional containerised solution provider with tens of years’ experience in this area. TLS teams are eager to give professional support to worldwide clients by providing premium quality containerised solutions.

Pressurised motor control centre (MCC) / power control centre (PCC) shelter located in hazardous zones
 
A motor control centre (MCC) / power control centre (PCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter, fuses or circuit breaker, and power disconnect. A motor control centre can also include push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. It may be combined with the electrical service entrance for the building.
MCC's are typically found in large commercial or industrial buildings where there are many electric motors that need to be controlled from a central location, such as a mechanical room or electrical room, called as MCC shelter.
 
When the above MCC / PCC is used in, around, or near an atmosphere that has flammable gases or vapors, flammable liquids, combustible dusts, ignitable fibers or flyings, there is always a possibility or risk that a fire or explosion might occur. Those areas where the possibility or risk of fire or explosion might occur due to an explosive atmosphere and/or mixture is often called a hazardous (or classified) location/area. The MCC shelter should be positively pressurised by fresh air blowed from safe zone through blower fan.  The whole pressurised MCC shelter is composed with sensors, fire & gas system, intelligent PLC, fire dampers, air-conditioner, etc. The MCC shelter is manufactured according to offshore DNV2.7-1/EN12079 standards, certified by CCS, BV, etc class societies.
