Top 5 Challenges In Wind Power Cable Management
Offshore Wind Power Cable Management
Roxtec Top 5 Challenges
Thorne & Derrick are Approved Distributors for Roxtec, the leading manufacturer of sealing solutions for cables and pipes, to protect electricity Transmission & Distribution assets including windfarm substations against water ingress, gas migration and fire hazards.
Below Roxtec have compiled the top 5 most common issues we all struggle with on offshore substations.
1. Specifications & Certificates
We all want to ensure safety and operational reliability, and use high quality products to deliver the best result we can. Therefore, we often meet specifications and requirements demanding a multitude of certificates. However, it is not guaranteed that all types of cable sealing methods are approved.
The best thing would be to find a sealing solution that has passed all tests and certifications.
2. Uncertain Estimates
It can be difficult to know how many cables or pipes, or what size power and instrumentation cables, we need to route. We can never be sure about making the right openings, or about how to seal all those penetrations. Even the best of estimates cannot predict all late design changes.
What we need is a sealing system that is as adaptable as possible to the number and size of cables, pipes or openings. It should be so flexible that we would be able to have spare capacity.
3. Hard Cables To Handle
It is difficult, or almost impossible, to move and bend a large high-voltage or medium-voltage power cable into the desired position for routing through a deck or bulkhead. It takes a lot of time to reorganize the routing path in order to gain a couple of millimeters of bending radius.
What you need is a solution where you can position and apply a seal to fit around the cables, even if they are in an off-center position.
4. Tricky Design Work
Given the issues mentioned above, the work of design engineers often becomes a nightmare. We need to plan, calculate and design in cable and pipe penetrations at an early stage considering both rollout and maintenance. Sometimes, it means recalculating each opening.
Imagine a web-based design tool that we can use to design and redesign transits in no time.
5. Time-Consuming Installation
We know renewables can save the climate, and we know speed is crucial and time is money. Therefore, it is so frustrating to struggle with sealing solutions that are neither flexible nor easy to install. We cannot accept that project plans fail due to complicated installation work tasks. We should only engage suppliers of user-friendly products who will also train the installation team.
Roxtec provides offshore wind farms with an “all in one” solution for cable entry sealing, cable management and vibration damping. Standardise with Roxtec seals for efficient offshore windfarm cable protection design, quick roll-out and certified protection – cables are securely fixed, sealed and cable lifetime is extended.

Mining Company Fined £3.6 million
after electricians sustain burns in the UK
A mining company has been fined after two electricians suffered severe burns in separate incidents. The owners of Boulby Mine in Saltburn-by-the-Sea, Cleveland were fined £3.6 million and ordered to pay costs of £185,000 after an investigation by the UK Health and Safety Executive (HSE).
Cleveland Potash Ltd, which runs the mine at Boulby near Loftus, admitted two health and safety breaches following arc flashes in 2016 and 2019.
A company spokesman said the firm “deeply regretted” the injuries and “important lessons” had been learned.
Teesside Crown Court heard that on the 3 August 2016 a contract electrician received serious burns from an 11,000-volt electrical system. The mine, which is owned by Cleveland Potash Limited (CPL), extracts organic fertiliser known as Polyhalite. The electrician unknowingly had placed a vacuum cleaner nozzle into a live electrical chamber. He had to be air lifted to Newcastle hospital specialist burns unit, where he was placed in an induced coma for 10 days.
On the 12 February 2019, another electrical contractor made contact with a live conductor on a 415-volt electrical system during electrical testing works and received serious burns. He was hospitalised for six days.
The HSE found deficiencies from the owner of the mine in risk assessment, planning of works, and shortfalls in providing warnings about which parts of the electrical systems the two electricians were working on remained live.
HSE inspectors said that the incidents were ‘easily preventable’ and that there were ‘significant failings’.
The first man suffered “very severe burns” to 20% of his body focused on his head, face, arms and hands and his “ongoing disfigurement, pain and disability is likely to be permanent”. The second man has “fortunately” made a full recovery after suffering burns to 8% of his body, the judge said.
Did you know? – While high voltage equipment does increase the likelihood and intensity of arc flash explosions, they can occur in any live electrical environment – even low voltage. Read The Blog | Why Is Electrical Safety Important?
LET’S CELEBRATE!
August marks the Anniversary of our very own Managing Director, Richard Derrick, who has now been with the company for 30 years! Congratulations Richard, here’s to another 30!

Insulation Piercing Connectors
Insulation piercing connectors connect and make electrical contact with conductor ends, whatever the conductor cross-section, type and insulation. Because they pierce the insulation during installation, preparatory work on the conductor, such as stripping or brushing the contact area, is eliminated when live working.
Insulation Piercing Connectors LV for Low Voltage Live Working & Cable Jointing
2DIREKT
The 2DIREKT clamp is connected directly to the distribution transformer screwing onto the transformer bushing and secured via a clamping groove and clamping screw. This reduces the amount of installation work and the risk of connection errors. No cable lugs have to pressed on, and no wire-end ferrules have to be fitted. There are fewer points of contact and transition resistance is minimised.
> 2DIREKT from PFISTERER | Connections & Clamps for Bushings & Busbars
ISICOMPACT
The ISICOMPACT establishes all contacts for a 4-conductor cable branch using a single screw connection – when the screw connection is tightened, contact is established by piercing the insulation on the main line and branch lines.
Once the required clamping force has been achieved, the screw shears off and thereby ensures successful installation. By providing protection against contact and thus against electrical hazards, the ISICOMPACT is designed for live line work on low voltage electricity networks.

Battery Storage | Portable & Fixed Gas Detection Monitors from Crowcon
August 8th, 2022
Battery Storage
Portable & Fixed Gas Detection Monitors from Crowcon
Introduction
The Paris Agreement on climate change holds nations accountable for reducing their greenhouse emissions and reliance on fossil fuels, thus driving them to invest and use renewable energies, such as solar and wind.
However, the sun doesn’t always shine and it’s not always windy – or it might be very sunny or windy, leading to over-supply of the grid. To ensure that renewables are used for maximum benefit, any excess energy they produce (i.e., that isn’t needed for the grid at that time) is stored in local storage facilities, which take the form of large batteries.
These release energy later – when the grid requires more power, or when there is less sun or wind, such as overcast nights or calmer, duller days. However, these batteries can only release energy for a few (between 1 and 12) hours, so their use is limited to short-term, energy-on-demand requirements.
Batteries are effective at reducing power outages since they can also store excess traditional grid energy. The energy stored within batteries can be released whenever a large volume of power is needed, such as during a power failure at a data centre to prevent data being lost, or as a back-up power supply to a hospital or military application to ensure the continuity of vital services. Large scale batteries can also be used to plug short-term gaps in demand from the grid.
These battery compositions can also be used in smaller sizes to power electric cars and may be further scaled down to power commercial products, such as phones, tablets, laptops, speakers and – of course – personal gas detectors.
Applications

Gas Hazards in Batteries and Other Power Storage Sector
Dangers
- Typical processes and associated gas detection issues
Li-ion battery fires
- A major concern arises when static electricity or a faulty charger has destroyed the battery’s protection circuit. Such damage can permanently fuse the solid-state switches into the ON position, without the user knowing. A battery with a faulty protection circuit may function normally, but it does not provide protection from short circuit
- At this point, a gas detection system can establish if there is a fault and may be used in a feedback loop to shut off power, seal the space and release an inert gas (such as nitrogen) into the area to prevent any fire or explosion
Leakage of toxic gases prior to thermal runaway
- Thermal runaway of lithium-metal and lithium-ion cells has caused numerous fires. Studies have found the fires to be fuelled by the flammable gases that are vented from the batteries during thermal runaway
- The electrolyte in a lithium-ion battery is flammable and generally contains lithium hexafluorophosphate (LiPF6) or other Li-salts containing fluorine. In the event of overheating, the electrolyte will evaporate and eventually be vented out from the battery cells. Researchers have found that commercial lithium-ion batteries can emit considerable amounts of hydrogen fluoride (HF) during a fire, and that emission rates vary for different types of battery and state of-charge (SOC) levels. Hydrogen fluoride can penetrate skin to affect deep skin tissue and even bone and blood. Even with minimal exposure, pain and symptoms may not present for several hours, by which time damage is extreme
Hydrogen and explosion risk
- With hydrogen fuel cells gaining popularity as alternatives to fossil fuel, it is important to be aware of the dangers of hydrogen. Like all fuels, hydrogen is highly flammable and if it leaks there is real risk of fire
- Traditional lead acid batteries produce hydrogen when they are being charged. These batteries are normally charged together, sometimes in the same room or area, which can generate an explosion risk, especially if the room is not properly ventilated
- Most hydrogen applications cannot use odorants for safety, as hydrogen disperses faster than odorants do. There are applicable safety standards for hydrogen fuelling stations, whereby appropriate protective gear is required for all workers. This includes personal detectors, capable of detecting ppm level hydrogen as well as %LEL level. The default alarm levels are set at 20% and 40% LEL which is 4% volume, but some applications may wish to have a custom PPM range and alarm levels to pick up hydrogen accumulations.

Switchgear Control Using Trapped Key Interlocking | Castell
August 8th, 2022
Switchgear Systems
In this article, Castell discusses how trapped key interlocking is implemented within switchgear control whilst maintaining system integrity.
Factors such as aging infrastructure, technological advancements, lack of investment, demands for cleaner and reliable ever-present energy, have significantly altered the scenery of the energy sector with switchgear systems becoming increasingly complex.
Switchgear systems can utilise or involve several incomers, earthing systems, making the integration of HV (High Voltage), MV (Medium Voltage), LV (Low Voltage) or switching incomers and common supply busbars potentially complicated. This not only increases the potential level of complexity but also the need for robust and reliable safety systems to ensure personnel safety, electrical equipment protection and its correct, safe mode of operation at all time.
The safe and effective operation of switchgear can be achieved through a sequential release system which sets out a process that must be followed removing the need for reliance on work instructions alone.
The system designer should consider the operational processes in conjunction with the safe state of equipment. A challenge with switchgear if one or more supplies shuts down due to an overload or power failure or for planned maintenance purposes is that the remaining supplies will have to carry the load. Therefore, the sequence of operation must be controlled in such a way to ensure that power is maintained, the shutting down of the remaining supplies due to overload is avoided and the collapse of the entire system is prevented.
Trapped key interlocking constitutes an effective way to control the sequential operation of switchgear systems. A trapped key interlocking system can ensure a process is followed and cannot be circumvented. The transfer of a key ensures that wherever personnel find themselves, in either starting or shutting down operations, they can be assured that they are safe through the control of switchgear isolation.
Management of complex switchgear systems can be controlled through a blanking system. The blanking system means that some of the symbols on the busbar locks have a part coded lock which denotes it can be isolated by more than one of the keys forming the switchgear system.
For instance, if we part coded a lock to A ‘Blank’ we can use any 2-character symbol keys with a prefix of ‘A’ to operate the lock (see below for more examples). The system’s integrity is maintained by the design of the nomenclature chosen for the incomer and busbars.
This means the open and closing operation of the switchgear can be controlled with less locks and keys. Blanking systems, although not suitable for every switchgear application, offer some significant advantages. More specifically, they remove the need for excess keys and additional key exchange boxes allowing for a simpler interlocking system. Implemented correctly, they can also provide cost and time saving benefits.
Applications
Applications for incomer and busbar interlocking or incomer, generator and busbar interlocking are used in any environment where there is a demand for reliable energy sources such as data centres or building management services like factories, hospitals, airports, rail and stadiums.
Example 1: Incomer and Busbar Interlocking
This system requires five locks and three keys. In the normal operation the keys are trapped in the incomers in the closed position and both bus couplers are open.
The symbol sequence will allow appropriate incomers to be open allowing the key to be released, transferred and inserted and trapped to the associated bus coupler allowing it to be closed. The symbols used here are AA, AB and BB for the Incomers and A_ (A BLANK) and _B (BLANK B) for the bus couplers.
Example 2: Incomer and Busbar Interlocking
This system will require four locks and two keys. The keys are trapped in incomer 1 and 2 with the switches in the closed position.
Both the bus coupler and incomer 3 open.
The symbol sequence will only allow incomer 3 or the bus coupler to be closed after the appropriate key has been released, transferred and inserted into the bus coupler or incomer three lock.
The system ensures that only two incomers are supplying at any time.
The symbols used here are AA and AB for the incomers and A_ (A BLANK) for the bus coupler.
Example 3: Incomer, Generator and Busbar Interlocking
The normal operation is the two incomers are closed with bus coupler and generator are both open. The symbol arrangement using key symbols AA, AB, A_ (A Blank) on locks with just keys AA AB will ensure safe switching operation.
It will not be possible to have incomer 2 and generator closed at the same time to avoid paralleling.
The symbols used here are AA and AB for the incomers and A_ (A BLANK) for the bus coupler.
Designing an interlocking system
The design of an interlocking system is a process that must be carefully undertaken. A good interlocking scheme requires all risks and operational procedures are considered in advance ensuring integrity. This can proactively address how the system will respond in both operational and failure modes along with routine maintenance.
An interlocking system will set out the process and steps that must be followed to ensure personnel cannot access potentially dangerous areas. When maintenance activities are being performed, trapped key interlocking systems can ensure that the switchgear system is always put in a safe state. Trapped key also ensures that the system operates efficiently and there is no chance of, for example, switching two incoming feeds on to a common busbar significantly reducing risks (such as fire, arc flash) as well as the possibility of equipment damage.
Conclusion
Complicated switchgear systems need to have a robust management system to protect personal and machinery. Designed correctly, an interlocking scheme can contribute to eliminating human error on site while permitting safe access to electrical equipment. Integration of older equipment with new switchgear can be a challenge, trapped key interlocking allows for the safe integrating with OEM switchgear, ensuring safe site operations and negating the need for complicated controls.
Castell have been delivering safety solutions for switchgear since 1922. Working closely with original equipment manufacturers (OEMs) has enabled Castell to produce interlocks designed specifically for use on the leading manufacturers own breakers, isolators, disconnectors and earth mechanisms. Castell offer a range of isolation products for switchgear applications.
The FS lock range can perform in the harshest environments using figure symbols as the unique identifiers enables defining a unique blanking system which allows for easier use of switchgear within the integrity of the trapped key system. FS locks can be incorporated into all Castell product for isolation equipment. Where isolation requires an un–masterable solution on switchgear, Castell Q range offers the ability to uniquely code locks to site requirements and as with the FS range, the Q range of locks can be used on all Castell isolation products.
