Industry leading subsea connector R&D and testing facilities Siemens Subsea Connector Excellence Center in Ulverston, UK

Testing is sequenced in such a way as to ensure the correct flow of information from each discrete test. Sequencing allows determination of the number of connector sets and parts required to satisfy qualification. Qualification is generally carried out in conjunction with an industry and/or client specification.

Our laboratory is a world-class example of its type, where individual components and materials are categorized – why is one better than another? Here, we conduct

fundamental research, looking at interactions between different materials: lifetime modeling – ageing oils and elastomers to simulate the age of the connectors and construct theoretical models.

For example, we analyze dielectrics – the quality of insulation. We simulate the ageing process so that if we guarantee 30 years’ product life, we have complete confidence in that guarantee. The machine we use is a FTIR (Fourier Transforming Infrared Spectrometer) – and at the time of writing there are only two of these machines in the UK. With this, we can analyze and assess the quality of materials right down to the molecular level, identify and assess faults and potential causes of failure, as well

understand why certain materials perform so well. The results of all such research and CCT (Critical Component Testing) are then fed back into product development and continuous improvement, de-risking the subsequent qualification programme. Additional development test equipment includes our test cages, up to 200 kV; our thermal cycling testing facility; our environmental chamber; and our numerous pressure vessels – up to 2,000 bar, with HV facility.

well to topside. The pumps increase oil recovery and can be specified for new field developments, or for existing fields to extend their life. SpecTRON 10 connectors have a nominal voltage rating of 6/10(12)kV, in accordance with the IEC voltage class system. This makes them suitable for 3-phase system voltages up to 12kV (Um).

Verification tests and results trending

To detect any deterioration of the component during the test programme, certain tests need to be performed throughout.

• Helium leak (He) test to verify seals upon completion

• Contact resistance (CR) test to determine resistance of connector assembly contacts

• Insulation resistance (IR) test to check insulation and check for presence of conductive contaminates

• High voltage (HV) test to check for build quality

• Partial discharge (PD) test – an insulation quality check

CR, IR, HV and PD are often carried out at the start of a test sequence and at the end, unless the test sequence plan states otherwise. Dismantling and examination is performed when deemed necessary, as outlined in the qualification sequence.

Electrical and thermal qualification tests

• Temperature rise test – qualifies the connector’s ability to run at full load current and beyond. Defines the test

parameters required to perform thermal cycling test

• Thermal cycling and extended thermal cycling – generally follows the heating cycles voltage test described in IEC 61442

• Thermal short circuit and dynamic short circuit test to demonstrate connector’s ability to withstand a specified short circuit condition and to determine compliance to future project requirements

• Electrical breakdown test to determine the voltage at which insulation breaks down

• Impulse voltage AC withstand test to assess ability to withstand transient over voltages (switching)

• Earth fault current test to determine if the connector pair earth circuit can conduct a project-specified earth current

Pressure (hyperbaric) qualification testing

• Hyperbaric mate / de-mate test (inc. partial mate / de-mate) to demonstrate that the connectors can successfully mate / demate at pressure; can be performed at extremes of temperature if deemed necessary

• Hyperbaric crush and flooded back end test to ensure the connector is able to withstand a number of surface recoveries and continue to function even with the primary barrier breached

• Hyperbaric long term test to ensure the connector is able to withstand long term service conditions (30 years’ service)

• Differential proof pressure and creep tests to establish the penetrator’s ability to withstand differential pressure, without loss of seal or

structural integrity (determine if the penetrator pin and associated components are susceptible to creep over an extended time period)

Mechanical qualification tests

• Thermal shock test to evaluate effect of rapid temperature excursions on components within the connectors

• Mechanical load / impact shock test to establish capability to withstand bending moments which may be accidentally applied during installation or service

• Cleaning and spillage test to ensure cleaning of marine growth, calcium or accidental spillage of chemicals can occur topside without degradation or damage

• Repeated misalignment mate / demate test / locking device test / mating forces test to ensure successful mate / demate at maximum misalignment

• Vibration, mechanical shock and endurance tests to ensure withstanding of vibrations, from flow pipes, rotating machinery, rough handling and transport

Non metallic hose, jumper and jumper termination tests

• Jumper / cable pull test to determine the mechanical strength of jumper swages and crimped joints

SpecTRON testingTo ensure reliability of our connectors, we conduct a rigorous test and qualification program.

Maximum current throughput is up to 520A, depending on the temperature and pressure inside the pump motor. This means the connectors can provide power to pump motors rated to 9MW (12,000 hp), or to 5MW (6,700 hp) for systems requiring Category C operation. SpecTRON 10 has been qualified to 450 bar test (4,500 meters) for use in deepwater to 3,000 meters. «

Adapting Siemens technology for use on the seabed

Dependable power supply and distribution is vital for any subsea processing facility. The Siemens Subsea Power Grid (SPG) Qualification Program is thus attracting great interest from the global oil and gas community. The grid is a complete medium-voltage power supply and distribution system installed on the seabed. It incorporates proven high-quality Siemens industrial components including subsea transformer, subsea switchgear and subsea variable speed drives, as well as a comprehensive power control and communication system. As one of the key enablers for subsea processing on a large scale, the Siemens Subsea Power Grid will be a standard-setting “game changer,” and will mark a milestone in powering large-scale seabed processing facilities that can reliably operate for long step-

outs and withstand extreme pressure and temperature conditions. Siemens’ confidence in its ability to configure complex power transmissions to multiple subsea consumers is grounded in our experience as a technology leader in land-based power grids with distribution to various consumers. By using proven Siemens technology and adapting it to subsea conditions, environments previously considered as ”harsh” by operators will, in the future, not be a challenge anymore.

Current project status Siemens is currently in the final stages of the five-year SPG program, taking a step-wise approach towards helping the oil and gas industry realize the transition towards the full vision of the subsea factory. The expectation is to be first to market with a power grid system with pressure-compensated electronics

qualified for remote deep waters.

The subsea transformer was already successfully tested in shallow waters in 2012. It is fit for purpose and the design verified with a market-ready product that is ready for a large power range. Pressure testing in the lab for various components and sub-assembly is currently being conducted in the Trondheim Pressure Lab. In late 2014 and 2015, switchgear, variable speed drive (VSD), the power communi-cations and control system as well as the complete power system will be shallow-water tested and qualified.

The availability of the Subsea Power Grid will allow operators to realize large-scale subsea processing. Later, the technology can be adapted to other industries that need power equipment on the seabed, such as deep-sea mining or the renewable industry. «

Deepwater reservoirs induce hydrate and wax formation, which can cause flow assurance challenges such as reduced capacity or even flowline and pipeline blockage.

Siemens’ direct electrical heating (DEH) power systems contribute to prevent wax and hydrate formation and to a consistent flow of hydro-carbons and despite challenging fluid characteristics and temperature conditions at the seabed.

They allow for OPEX savings through reduced chemical injection and dumping into the sea, in addition to low CAPEX and maintenance costs while also avoiding depressurization during shutdown. Combined with Siemens’ customized power design and components, they help to further increase system reliability and lifetime performance.

Typical containerized DEH solution
