Inertia and a resistance to change prevents progress even where the allure or reason for the initial attraction has long since past.
Working with Marechal, a world-leading manufacturer of industrial plug-socket assemblies, Thorne & Derrick can provide increased safety and improved reliability compared to the traditional “hard-wiring” approach to low voltage power distribution using their innovative Decontactor technology.
Marechal Decontactors can be disconnected under full electrical load for planned maintenance or rapid change out of equipment during plant shutdowns and turnarounds.
Marechal plugs feature a safety button placed on the upper section of the safety socket enabling the user with a single press of the button to disconnect the equipment up to 250A – no specialist skills or training is required to install the plugs.
Marechal plug-socket assemblies can be removed in complete safety – the power outlet installation is safe and does not represent an electrical hazard guaranteeing operating speed and time savings during installation operations or machine shutdown.
As an additional feature a safety shutter protects the user according to IP4X/IPXXD – the live contacts are inaccessible behind the closed shutter.
Electrical power can be controlled and distributed up to 1100V, 660Amps using the Marechal P66 high voltage connector for industrial applications.
The Marechal decontactor is a plug and socket with an integral load-break switch – this unique design offers various benefits :

Protecting Workers by Reducing Pinch & Crush Injury
uploaded by Chris Dodds | Sales Marketing Manager at Thorne & Derrick
Thorne & Derrick are Specialist Suppliers to the UK and international Renewable Energy Industry of products and equipment to provide safe and reliable LV HV Electrical Cable Termination, Jointing, Tooling & Installation of Power Systems up to 66kV.
This article covers the introduction of a Hand Safety Measure to reduce risk and improve safety for workers in the offshore wind industry involved in both construction, operations and maintenance (O&M).
Thorne & Derrick working closely alongside a multinational power company leading the energy transition from fossil-based to renewable generation of electric power have introduced a significant improvement to industry Health & Safety.
The adoption of the innovative ShoveIt product from Hand Safety Tools will reduce hand injuries while working with suspended loads or manoeuvring objects in offshore wind turbine nacelles. This could include manual handling activities, such as moving suspended heavy items including tooling, equipment, kit personnel bags to the work area.
Thorne & Derrick, a leading Distributor of Personal Protection & Site Safety Products, were invited to propose product recommendations to ensure a “hands-free” working procedure for turbine technicians and workers guiding suspended or hoisted loads into and out of nacelle loading hatches.
A Risk Assessment identified potential hand injury hazards relating to Pinch-Points when manoeuvring, grabbing, guiding and positioning suspended loads – the mitigation measure required adequate working length (up to 1.75m), lightweight for ease of use and allowance for a tool lanyard attachment.
Following risk review, Thorne & Derrick submitted the ShoveIt product for field trail and evaluation over a 2 week rotation period to gather collective performance feedback from the clients team – the 72” Length Rubber Insert Shove-It Hand Safety Tool was concluded to be optimal for the safe movement of the loads.
During the product trial the No Touch Hands Free safety tool was field tested during all weather conditions to ensure its suitability, particularly in high wind and low temperature periods (affecting grip ability) when conditions for manoeuvring loads into and out of the hatch can be most difficult and dangerous.
This Hand Safety Tool is made from non-conductive materials and features a rubber insert that provides a secure grip on the load without damaging it – the lightweight design makes it easy to handle, even in windy conditions. The tool lanyard attachment allows the operator to secure the tool to their wrist or harness, reducing the risk of dropping the tool and causing an accident.
The ShoveIt tool was found to be very effective in guiding loads in and out of the Nacelle loading hatch and the client was delighted with the results – ShoveIt has now been introduced by the H&S Team into their working Method Statement to reduce hand and finger injuries to the turbine and deck crew working across Irish & North Sea assets.
The ShoveIt Hand Safety Tool pictured in field use within a wind turbine tower to safely guide hoisted loads into and out of the nacelle loading hatch avoiding manual dragging and associated injury.
The load movement, handling and transfer of items from the Crew Transfer Vessel (CTV) to an asset via a crane mounted on the TP external platform can involve risk and exposure to potential hand injury accidents and incidents during the physical handling of loads.
The ShoveIt No Touch Push / Pull Pole Hand Safety Tool helps avoid hand injuries while working with suspended loads or manoeuvring objects across all industries. Users maintain proper ergonomic body positioning for safe handling out of the line of fire – this enables users to guide loads, move and position objects, as well as grab slings and taglines without physically placing hands on the item.

Thorne & Derrick are Approved Distributors for CSD Sealing Systems – we have specified and distributed their products across numerous onshore and offshore substation projects.
CSD Technical Services were recently contracted to carry out water and gastight sealing of cable entry points.
This was on a DNO substation at a council maintenance and storage depot. This was also a part of an action plan to reduce carbon emissions across the site.
Using CSD’S NOFIRNO Duct Seal System distributed by Thorne and Derrick, it has successfully sealed all entry points, helping to prevent any water or gas ingress in the building.
Completing the seal with a 20mm layer of NOFIRNO sealant will provide a technically advanced and high performance duct seal. View the complete range of CSD Sealing Systems to protect against damage caused by water ingress, gas spread or fire/flame to cables and ducts.
NOFIRNO | Substation Sealing | CSD The NOFIRNO Duct Seal is designed to provide simple and effective long term building entry sealing protection. The system can be used in new build projects or in retrofit applications to replace existing failing seals. It can be installed directly into concrete openings, plastic ducting or into any existing transit frames.
The site remained operational throughout the installation, with CSD working alongside and in partnership with other contractors and existing site workers. The NOFIRNO Duct Seal System was the selected solution for sealing the entry points.
All entry points into the substations were successfully sealed using CSD’s NOFIRNO Duct Seal System to prevent any water or gas ingress within the building.
This was to ensure the site remained operational. The openings within the control room which consisted of 37 x 160mm cable ducts and a 1 x 690mm x 900mm cable entry, was sealed along with a 1 x 230mm x 430mm cable entry in the DNO building.
A second visit to site was made to remove 1 x 150mm installed seal following the installation of an additional cable. This seal was then resealed using the NOFIRNO Duct Seal System. The client feedback was very positive, and they will be looking to use CSD for future projects.
The NOFIRNO Seal System comprises of two components; 60mm rubber NOFIRNO multi-sleeves which providing the cables with support, ensuring separation.
It helps provide a backing for the second component which is a 20mm layer of NOFIRNO Sealant. To ensure the NOFIRNO Sealant adheres correctly, the areas where the sealant is to be applied should be clean and dry before application.
For example the cables and any frames and structures. The NOFIRNO multi-sleeves are then installed providing cable separation and a firm backing for the NOFIRNO Sealant layer.
NOFIRNO duct seals consist of rubber multi sleeves which are in bonded strips of 10 sleeves and a high quality silicone based sealant which are quicker and easier to install than the CSD standard RISE duct seals.
The bonded sleeves can be easily torn off for filling smaller gaps and using cutting tool sleeves can be quickly slit to allow fitting around cables ensuring cable separation – NOFIRNO duct seals are also used to pack the free space, providing a backing for the application of the cable sealant.
• Tested to prove no deterioration in performance
• Provides flood protection and prevents water and gas ingress. The pressure is rated up to 2.5 bar from the front and back of the seal.
• Quick and easy to install
• Easy re-entry for adding, removing or replacing cables

NOFIRNO | Sealing Substation Cables | 400kV High Voltage (HV)
CSD Sealing Systems were recently contracted to carry out water and gastight sealing of cable ducts on a newbuild High Voltage substation project where the previously installed seals were leaking.
The NOFIRNO® Duct Seal System was used to successfully seal all entry points so that all buildings were water and gastight, helping to prevent water ingress, reduce the risk of equipment damage and ensure the site remains operational.
CSD Technical Services were contracted to carry out water and gastight sealing of cable entry points on this new build substation project. This substation would prove to be one of the largest built substations built across the UK and would ensure the transmission of renewable energy generated from a new offshore windfarm.
The NOFIRNO Duct Seal is designed to provide simple and effective long term building entry sealing protection. The system can be used in new build projects or in retrofit applications to replace existing failing seals. It can be installed directly in to concrete openings, plastic ducting or into any existing transit frames.
Sealing Substation Cables
The previously installed seals were leaking and therefore the client was concerned regarding the damages these leaks could bring to their assets. The NOFIRNO Duct Seal system, manufactured by CSD Sealing Systems and distributed in the UK by Thorne & Derrick, was the preferred solution to prevent flood damage to the high voltage (HV) cables and electrical infrastructure.
Outcome of Using Duct Seal Systems
All previous sealing materials were carefully removed ensuring that no cables were damaged during the removal. Following removal of the failing seals our team thoroughly cleaned all cables and the duct openings to remove all old sealant and any dirt, dust, and concrete.
All entry points were successfully sealed across the site using CSD’s NOFIRNO Duct Seal system. All buildings are now water and gastight helping to prevent water ingress and reduce the risk of equipment damage and ensure the site always remains operational.
The NOFIRNO Duct Seal system comprises of two components; 60mm rubber NOFIRNO multi-sleeves which provide cable support, ensure cable separation, and provide a backing for the second component which is a 20mm layer of NOFIRNO Sealant.
To ensure the NOFIRNO Sealant adheres correctly, the areas where the sealant is to be applied should be clean and dry before application i.e., the cables and any frames/structures. The NOFIRNO multi-sleeves are then installed providing cable separation and a firm backing for the NOFIRNO Sealant layer. The system will provide a water and gastight seal to certified levels of 2.5 bar and has been shown to provide protection for a period of at least 50 years.
• Tested to prove no deterioration in performance for more than 50 years
• Providing flood protection and preventing water and gas ingress – pressure rated up to 2.5 from the front and back of the seal
