pROJECTS & NEWS 

Floating production storage and offloading Unit

This month we have been working on a project to supply electrical safety equipment to switchrooms on a floating production, storage and offloading platform (FPSO) located in the North Sea – a floating production storage and offloading (FPSO) unit is a floating vessel used by the offshore oil and gas industry for the production and processing of hydrocarbons, and for the storage of oil. Ship-shaped FPSOs are by far the most widely used type of floating production unit, accounting for over 100 deployments globally.

The customer required a replacement for their current insulating matting to be installed in their LV and HV switchrooms on board the FPSO. The replacement was required due to the age of the existing matting; showing typical wear and tear and no longer providing the correct level of safety or insulating protection to offshore workers.

The switchrooms on the vessel ranged from 1kV to 17.5kV, and required matting to meet the correct voltages. After careful project specification, Thorne & Derrick supplied the client with Class 2 insulating matting for the HV switchroom, plus Class 0 matting for the LV switchroom according to IEC6111. Each versatile roll was supplied at 10 x 1m wide, with the end user intending to cut the rolls to suit the individual requirements.

Thorne & Derrick supplied the materials in 3-4 days from stock – see also storage, use and care of insulating matting for further information.

It involves a subsea development of production and water injection wells tied back to a floating production, storage and offloading vessel (FPSO) with oil export using shuttle tankers.

improving access

A pair of new lifts has been installed at Meols station to improve accessibility for those travelling on the Merseyrail network.

The £2.2 million project was funded through the Department for Transport’s (DfT) Access for All programme and forms part of a wider project funded by both the DfT and Liverpool City Region Combined Authority.

The Access for All programme was introduced to make travelling more convenient for disabled passengers travelling by train across the country, and previous projects on the Merseyrail network include lift installations at Formby, Birkenhead North and Orrell Park.

Green Energy Transition & The Electrification of Society By Roxtec

Green Energy Transition & The Electrification of Society By Roxtec

Green Energy Transition By Roxtec

Cable & Pipe Transits

The Green Energy Transition and the electrification of the society put pressure on the power industry. Sustainable power generation, efficient transmission and distribution, and safe storage are some of the challenges that call for smart protection of equipment against multiple risk factors. That is why Roxtec cable and pipe transits are omni-present – from solar plants and wind farms to long-distance HVDC and grid projects.

As experienced penetration seal provider, Roxtec is involved in the energy transition and contributes to renewable hybrid projects as well as energy storage and balancing of the transmission and distribution grids. The company has a long story within wind power and is cooperating with all major offshore wind operators.

Roxtec provides cable duct seals and expertise to wind farms on land and to solar power plants as well, and participates in a variety of development projects within renewable power generation. With an impressive collection of tests, approvals and certificates, Roxtec also supplies seals to nuclear power projects.

---

Efficient storage and use

Generating power is, however, not enough. There is a need for reliable energy storage that enables a balanced and optimized use of the electricity grids. When you can store energy, you can take care of the complete harvest from your solar plants and wind farms, even when the grid is too full to handle it. Roxtec is working with world leaders in energy storage, but also within green hydrogen. The latter enables efficient use of excessive renewable energy for preparing green hydrogen instead of wasting it.

Ensuring HVDC transmission

There is also a need for increased transmission to accelerate the transition. The UK is a good example with both extension of offshore wind power and transmission through HVDC, high-voltage direct current. Roxtec follows the cable and provides sealing from the submarine to the land-based cable.

Rob Cullen, Power Sales Manager, Roxtec UK

“We became aware of drawbacks with traditional methods of sealing cable ducted systems between the shore and the local substation. As we have great relationships with cable manufacturers, project developers and delivery partners, it was a simple decision for them when we were able to bring both standard and bespoke sealing solutions,” says Rob Cullen, Power Sales Manager of Roxtec UK, and continues:

“They can now save significant time since Roxtec installations do not require curing time. Our seals also provide advantages in terms of cable management and retention whilst being vermin-proof. When our customers understood we provide training and technical support, they were very happy. As result of this mix of product and support we have managed to secure two major landfall projects and one underground transmission project in the last eighteen months.”

---

Batteries for charging

Another example within distribution is found in The Netherlands. A growing manufacturer of industrial modular energy storage systems that can be used for every conceivable application such as energy storage, balancing of the electricity grid or fulfill temporary energy requirements, is using Roxtec seals to protect the mobile and stationary battery containers against fire, gas and water.

The industrial storage systems are also used in solar plants of all sizes to enable storage of the produced energy until the right time for usage.

In the same region, Roxtec has become the preferred supplier of seals to onshore landing stations for offshore wind power. The cables used for connecting energy from distant turbines to the onshore grid must be protected from environmental threats, electromagnetic interferences and effects of lightning strikes.

Therefore, the engineering and construction companies have specified Roxtec seals for shielding, bonding and grounding. One landing station can receive power from several offshore wind farms and can have more than 1,000 openings to seal.

Hans Durinck performing installation training with customers onsite

“The thing is to always provide good service,” says Hans Durinck, Manager Outdoor Sales of Roxtec Netherlands. “I often go onsite, and the owners and all the different contractors know that they can call me any time if they have questions regarding our safety solutions. I will not ever try do their job, but I can certainly take away some of their troubles. We know sealing, so we bring peace of mind to them.”

---

CABLE TRANSITS

Roxtec cable transits are used to prevent water, gas, fire, dust and rodents from entering cable duct openings and potentially causing damage to cables and other electrical infrastructure.

Cable transit systems can be designed for sealing medium/high voltage substations including 11kV/33kV and “triplex” type cables in single, multiple or trefoil configuration.

Roxtec modular cable transit seals are based upon a rubber design with seals that are constructed of a number of removable layers to secure a watertight, gas tight and fire proof seal around the cable or pipe – the range includes rectangular transits and round transits to fit a variety of pipes and cable sizes.

Cable transit products ensure safety, reliability and efficiency by providing an effective, dependable seal around cables and pipes through an opening, penetration or duct.
