Hydril Pressure Control Subsea Pump

Subsea Pumps Comments Off

Hydril Pressure Control Subsea Pump photo subsea pumpsOver $50 million was invested in the development of the MudLift pump, not only on equipment, but also in defining and writing well control and operational procedures for the entire system. These efforts have resulted in a pump with features that include:
• Discharge pressures to 6,600 psi which means it can operate in water depths to 10,000 ft
• Flowrates from 1,800-4,000 gpm for drilling and mining applications
• Positive displacement technology which provides high system efficiency and unsurpassed solids handling capability
• Actuated valves that guarantee positive shutoff in the presence of solids – large particles that would prevent other valves from closing completely are sheared by the valve’s design
• Powered by seawater, the MudLift eliminates the requirement
for high power subsea power distribution and provides a use for the transport water used during mining applications
– seawater is returned to the sea
• Seawater power pumps located on deck and available for easy maintenance

Subsea Multiphase Pump Compressor – SMPC

Subsea Pumps Comments Off

Subsea Multiphase Pump Compressor   SMPC photo subsea pumpsThe Bornemann Subsea booster (SMPC) is the consequent further development of the subea Multiphase Pumps and the heavy duty topside Multiphase Pump type MPC.

The new Double-Pressure-Compensated (DPC) pump design provides the basis for the new Subsea Multiphase Pumps.
It basically consists of two main components:

The pressure casing, rated for water depths and process pressure.
The pump-motor-module, including all rotating equipment.

Subsea Boosting

Subsea Pumps Comments Off

Subsea Boosting  photo subsea pumpsAs offshore production moves to deeper, more harsh environments, the use of surface structures is becoming prohibitive due to complexity and cost. This has led to subsea processing, which has created a new emerging market for processing equipment.

Advantages of Direct Drive Systems® Permanent Magnet Motors
Smaller Rotor Diameters: For the same power level, our PM motor rotors are smaller when compared to induction motors. Since the friction losses in a flooded motor are related to the diameter of the rotor, our motors incur significantly lower mechanical losses.
Larger Air/Liquid Gaps: Since subsea motors are flooded, the distance between the rotor and the stator is actually a liquid gap. Due to PM characteristics and Direct Drive Systems’ proprietary designs, the motor gap can be increased up to 20 mm., compared to 4 mm. for induction motors. This increase not only provides lower mechanical losses, but also provides the opportunity to introduce canning between the rotating and stationary parts of the motor to prevent any process fluids or gasses from entering into the electric systems.
Higher Speed of Operation: Currently, induction motors are limited in their speeds (approximately 3,800RPM). However, if the motors could operate at much higher speeds, the hydraulic section of the pump would become more efficient (by up to 4 percent). The differential pressures would also increase, enabling the pumps to be installed in deeper waters – a significant advancement for deepwater projects such as in the Gulf of Mexico, where the water depths can approach approximately 9,842 ft. (3,000 m).
Qualifications: Currently, all subsea pumps utilize fluids pumped from the topside through the umbilical. If the pump systems can survive on regenerative Monoethylene glycol (MEG), already utilized in the well, both installation and operating costs would significantly decrease. We are qualifying our motors to operate in regenerative MEG.
System Level Benefits: Besides the pump system benefits of our PM motors, there are also complete system benefits. Due to the energized permanent magnets, Direct Drive Systems’ PM motors operate on a constant torque basis, which means that our PM motors can provide full torque at any speed. They are not dependent on speed like induction motors. This unique property provides quick startups, and therefore, the complete electrical system does not have to be rated for the startup conditions. For example, an induction motor requiring 400AMPS will need 1,600AMPS during start up, which means the electrical system (cables, drives, penetrators, and transformers) all must be rated for 1,600AMPS, whereas Direct Drive Systems’ PM motors will never exceed 400AMPS for the same working conditions. This is a significant cost savings, especially when longer step outs are used.

Framo Subsea Pump

Subsea Pumps Comments Off

Framo Subsea Pump photo subsea pumpsThe Framo Subsea Pump Control System (SPCS) offers seamless integration of subsea and topside control systems and is tailor made for subsea boosting applications. The Framo SPCS ensures optimum operation of the subsea system with both high reliability and high availability.

The Framo SPCS has been developed in order to ensure:
Safe monitoring and control of subsea pumps and compressors
Provision of a high data rate communication link for any subsea instruments
Performance of traditional production system operations

The subsea pump control system is also suited to operate subsea satellite and full field developments as subsea production control system. Beside the primary objective of safe operation of the subsea equipment there are two other important aspects that have driven the development of the SPCS. First, provide an open architecture that enables inclusion of various instruments subsea for improved control and condition monitoring. And second, the ability to provide a high capacity communication link with bandwidth control, in order to fully take advantage of subsea instruments like MulitPhase Flow Meters and other data intensive instruments.

SPCS has been supplied for many projects and are operating a wide range of systems:
Subsea multiphase pump systems
Subsea multiphase compression systems
Subsea multimanifold systems (including production trees control)
Subsea raw seawater injection systems (including water injection trees control)

Curtis Subsea Pump

Subsea Pumps Comments Off

Curtis Subsea Pump  photo subsea pumpsCurtiss-Wright EMD has been designing and manufacturing critical application pumps since the first nuclear submarine, the USS Nautilus, was built in 1952. Today, our unique, patented marine pump and motor designs continue to set the standard for performance and reliability and have led to product innovations in the commercial markets.

Curtiss-Wright, in partnership with Petrobras, Brazil’s international energy company, and Leistritz Corporation, a manufacturer of specialized positive displacement pumps, developed a state-of-the-art submerged, canned electric motor and multi-phase pumping system for deep-sea oil recovery. Subsea multiphase pumping systems enable and optimize production from the growing number of deepwater reservoirs being developed in the Gulf of Mexico, West Africa, offshore Brazil and other parts of the world. In addition to providing the power needed to lift oil from the reservoir to the platform, Curtiss-Wright’s pumping system also creates the potential to accelerate the oil production rate by as much as 50%, providing a dramatic increase in return on investment for our customers. Curtiss-Wright’s first system is being deployed by Petrobras in the Campos Basin’s Marlim Field offshore Brazil at a water depth of 640 m (2,100 ft).

In 2006, Curtiss-Wright formed a joint venture with Cameron International Corporation to market and supply subsea multiphase pumping systems to the international offshore oil industry. The joint venture combines the motor and pumping system expertise of Curtiss-Wright with the subsea systems integration experience of Cameron, a world leader in the supply of subsea equipment.
