Heat Exchanger Motors.
We now offer a complete range of water filled, watertight, submersible subsea motors with integral heat exchangers in 10-inch, 12-inch, 14-inch and 16-inch size for 2 pole and 4 pole speeds.
These subsea motors offer a significantly lower temperature rise when compared with standard submersible subsea motors. This is an advantage that can be utilized when customers want to operate in water with a high ambient temperature, or when there will be minimal cooling water flow available. Even with the standard applications the lower temperature rise will extend the life of the motor significantly. There is an accepted rule of thumb for electrical insulation that its life is shortened by one-half for every 10°C increase in operating temperature. The winding operating temperature for a normal water filled submersible motor is about 70 degrees.C, in 25 degree.C water. However an SME Heat Exchanger Motor will be running at about 45 degree.C. (This is 25 degrees cooler). This magnitude of difference in temperature rise will have a significant positive impact on motor life.
The basic design principle for these subsea motors is to circulate the internal water in the motor remove the heat from the "active" parts of the motor, and then pass it through a heat exchanger which brings the internal water back to somewhere close to the external ambient water temperature - before feeding it back through the "active" parts again to remove more heat. The heat exchanger increases the external surface area of the motor by 50% and the water circulation allows the heat to dissipate more evenly and quickly out of the subsea motor and into the external water. The small impeller inside the subsea motor that circulates the water has an insignificant impact on the motor efficiency in terms of additional load, while the subsea motor has an improved efficiency because the stator and rotor copper losses are reduced due to the lower operating temperature.
Motor Thermal Protection Unit
All SME Heat Exchanger Motors come with four (4) PT100 temperature sensors installed in the motor. One PT100 is attached to the thrust bearing assembly that will detect excessive thrust loads and overheating in the thrust bearing. One PT100 is installed in the end winding on the non-drive end of the motor. One is installed half way down the slot in the winding in the middle of the motor. One is installed in the end winding on the drive end of the motor.
SME can offer one temperature protection unit (SME4TM) to monitor all four PT100'S installed in the Heat Exchanger Motor.
Water Pump Motors. Our water pump motors are not vertically oriented, water filled, down hole pump motors, as has previously been the norm throughout the subsea industry. Silvercrest/SME motors are substantial oil filled submersible motors, designed to run in the horizontal axis with a large thrust bearing assembly to withstand water pump loads. We can offer specially designed turbine pumps to match our motors. Again these pumps are not the usual vertically oriented type, these are specifically designed with a twin bearing arrangement, for use in the horizontal axis. Thus dramatically extending operational life and improving pump reliability. Silvercrest recently delivered ten 260kW, 3000VAC, double ended, 2 pole, stainless steel bodied motors to CTC Marine Projects Ltd. The motors will be used by CTC on their subsea plough and trenching vehicles worldwide. This was a bespoke order that was completed in six weeks from receipt of order, ex-works from our manufacturing facility in Australia. The 260kW/ 3000V / 60Hz / 2 pole pump motors (designed specifically for use in the horizontal axis) were fitted with shafts at both ends, in order to mate with three tandem mounted hydraulic pumps on one end and a Hayward Tyler M6 single stage water pump-set on the opposite end. In this 260kW model, rather than using the pivot shoe arrangement, typical of vertically oriented pump-sets, heavy duty tapered roller bearings were fitted to the rotor to manage the water pump induced end-loads. Thus giving a calculated bearing life in excess of 11,000 hours, even when used in the horizontal axis. Depth rating on each motor is 10,000 meters, with oil filled compensation. Motor housings are 316 stainless steel, with Mylar coated windings (the ultimate in winding coating technology) being used in each motor at the request of CTC, giving an insulation rating of >16kV at a temperature of 140 degrees C.
Rov and Subsea Plough and Trencher Motors. Silvercrest offer an established range of Rov motors ranging from 5HP to 500HP. All of these motors are available in either SS316 or Hard Anodized Aluminium finish. We will also design and build submersible motors to suit your individual requirements and subsea project. Our motors are in use with most of the major operators worldwide such as Saipem, SMD Hydrovision, Sonsub, CTC Marine Projects, Impresub, Fugro, Thales, MTQ, LD Travocean and Canyon Offshore.

We can supply ROV HPU submersible motors from 30kW to 250kW, trenching HPU submersible motors from 100kW to 450kW, trenching jetting pumps, plough HPU submersible motors, plough jetting motor pump sets, turbine and centrifugal water pumps, hydraulic pumps, Rexroth A7 and A10 series pumps, and Sauer 90 series & Kawasaki KV3 series pumps. We also offer a range of subsea components for manned submersibles, ROVs, submarines, subsea trenchers and subsea ploughs. Also oil compensation units (Compensators). We supply AC thrusters as direct replacements to existing DC thrusters from 1kW to 50kW in size.
Oil Compensator Units. Silvercrest/SME supply oil compensator units for subsea vehicles, to suit manned submersibles, ROVs, submarines, subsea trenchers and subsea ploughs, and subsea equipment. We can offer a range of oil compensation unit sizes, including a 2.7L Compensator. 7 x 1/4" NPT (BSPT). SA-HC-0745-MAS.
This is a rolling diaphragm, positive pressure compensator (2700cc capacity), manufactured in corrosion resistant plastic suitable for ROV and tooling applications. These units are particularly suitable for compensating thrusters, compensating oil filled junction boxes, compensating valve packs, and other subsea applications
Motor-pump sets (depth rated to 3000m) for subsea trenching operations. Silvercrest/SME has recently manufactured and supplied two 265kw motor-pump sets for SMD-Hydrovision (England). The package comprised 265kw subsea motors, 2-pole, 3000v, 3ph, 60hz. Together with Jetting Pumps (wet end only, operating at 2-pole, 60 hertz). The motors were a stainless steel construction, and the pumps Zinc Free Bronze. These motor-pump sets will be installed onto one of the world’s largest subsea trenching vehicles. In addition, Silvercrest /SME has manufactured and delivered in just eight weeks from order, two water turbine pumps to CTC Marine Projects based in Teeside (England). The pumps will be used by CTC, in conjunction with Silvercrest/SME submersible 260Kw motors, on their subsea plough and trenching vehicles worldwide.
The two Silvercrest SH-M6R submersible pumps with a 231mm OD impeller and a nominal operating speed of 3600rpm will be used as an alternative to the Hayward Tyler model M6-1 stage CI/BR/SS submersible pump. The Silvercrest pump although matching the performance of the Hayward Tyler unit, is specifically designed for horizontal operation providing a greatly increased reliability for use in horizontal and downward angled operation.

Unlike a down hole pump motor such as the HT Sumo, our motors do not use pivot shoe thrust assemblies. As a result our motors are compensated for depth pressure using oil rather than distilled water as in the case of down hole pump motors. Unlike most motor manufacturers, we manufacture our own core laminations on site, affording maximum flexibility in design. We can bespoke manufacture virtually any shape of motor you may require. In this 260kW model, rather than use the pivot shoe arrangement, we fit heavy-duty tapered roller bearings to the rotor to manage the water pump induced end loads. Thus increasing the reliability and service life of the motor by a factor of 10 or more when used in the horizontal axis. Our superior Mylar coated windings are the ultimate in winding coating technology. Mylar coated windings have an insulation rating of >16kV at a temperature of 140 degs C. No other winding coating even comes close to this standard. We can offer you submersible motors with the following specification:-
