Guys, Please give me a shed of light. What is the Explosive Decompression ? Regards, RK

All, I need your guidance in my problem following. We would like to buy a communication cable to transmit the signal from signal source to the final actuator. The signal transmitted by mean of MODEM. The distance from the source is about 23 km. We already have about 10 km cable, and we would...

All, Please give me a shed of light on following things. What does it mean 120V 2 phase system, is the 120 V is line voltage or line phase ? how we can have this system ? If i have equipment required 120 V 1 phase system(with neutral, how do i connect to the power system above ? Cheers, RK

Kat, Is your SUTA attached to the umbilical or not? How big the SUTA is ? Perhaps you can utilize an umbilical basket which can deploy with SUTA. However, if the MBR of the umbilical is big, this method is not practical. Currently i have some problem as well in designing the SDB, we think that...

All, Actually the subsea control system vendor have designed the system as what AcesHighJoker advice. Not only the valve, they already put some Hydraulic accumulator subsea. The intention is to maximize the response time. The umbilical only supply the hydraulic pressure to Subsea Accumulator...

Hi Chief, I don't understand with what you are saying. Till now, i have no idea if there is subsea production control system using microwave signal to communicate with subsea control module. Could you provide an information little bit more on this ? Regards, 13392017

Hi Kat, I believe, what you saying here is the communication between Master Control Station and Subsea Control Module through the MODEM. The vendor of subsea control system usually use Half duplex communication and using industry standard FSK NRTZ, however, the vendor usually already have their...

Guys, At the moment, i am looking for the mention subject product. Can you provide me an information on the technical and manufacturer ? Thank you in advance Regards, KR

Hi Kat, I think you can go to website of Umbilical manufacturer such as DUCO or JDR.For the installation you can go for SUbsea7, Technip or Stolt. Regards, RK

Hi jbthiel, Correct, the pump goes to near zero flow. But, it's depend on pressure inside system. In braking mode, the application has some mechanism to decrease or increase operating pressure depend on required braking torque. So, oil will always circulate through oil cooler. Regards, RK

Thanks MortenA, Of course if we choose subsea completion, we will not need any jacket. But the cost to have some subsea completion are very high if you compare with others, especially if in life of field we have some problem with the well. To rent the vessel, they daily rate is amazing...

Gents, Please share your knowledge on selection of subsea completion instead of platform/dry tree, etc. Regards, 13392017

Gents, Appreciate your valuable help on my problem. We select variable vane pump with pressure compensated, because between subsystem/aplication has different requirement on flow rate and pressure. At that time, we think once the pressure reach the setting, the flowrate will be zero. To...

Hydromech.. Setting pressure for system relief valve is 1500 psi. For the pump, we used Rexroth PV7-1X/25-30RE01MC0-16, max.displ. pump is 30 cm3/min; hyd motor Rexroth MP 80/610-F-202, displ. 80 cm3/min; Directional control valve, Atos DHZO-A-0530S5/PA-NPT/7, max. flow 70 l/min. Regards, RK

Hydromech,Budt I will answer one by one, 1. when the brake operate, there is other system/application which pull some wire/cable from wheel of system. This braking system objective is to give some constant tension, which is set by hydraulic brake pressure. This constant tension made by some...

Gents, We just built some hydraulic application which uses variable pump, fixed disp. motor, hydraulic brake, directional control valve etc. In this application, there are two subsystem, one system to brake the wheel, and another is to turn the wheel. Both application are not work...

Dear All Does anyone know what an Annulus Valve is and what it does in a christmas Tree? Thank you for your help

Dear All, I need your advice regarding installation of sensor on 2" high pressure (10000 psi). Is it OK if we just drill some hole and make a thread match with the sensor ? or there is some specific requirement for this. Regards, RK

Dear All, I'm looking for a hand or foot operated pump, double stroke (if any), 50 – 500 cc disp/ stroke with max. pressure 2000 PSI . If you have any information regarding this matter, please share with me. Thanks in advance. RK

Thank you Greye for your valuable input. Best Regards, 133392017 aka aRKey
