Introduction

A magnetic solution is a mounting or attachment method that uses permanent magnets, typically neodymium, to fix equipment to a steel structure without welding, drilling or bolting. In offshore engineering, this replaces installation methods that would otherwise require hot work, surface penetration or permanent structural modification.

We build our magnetic systems, including the V-Mag© series, around this same principle: attach fast, hold reliably, and leave the surface as it was found.

How do neodymium magnets like the V-Mag© series work in industrial mounting?

Neodymium magnets are the strongest commercially available permanent magnets. The V-Mag© 70 and V-Mag© 340 use this material to generate holding force high enough to secure brackets, cable trays, tools and instrumentation directly onto ferrous steel, without any mechanical fastening.

Because the magnet itself carries the load, there is no need for a welded seam, a drilled hole or an adhesive cure time. The unit is positioned, engaged and load-tested on site. On a wind turbine tower, an offshore platform deck or a vessel hull, this means installation happens in minutes rather than the hours a welded connection would take, including setup and cooldown.

What makes a magnetic solution non-penetrating and non-destructive?

Non-penetrating means the surface is never drilled, cut or welded. Non-destructive means that once the magnet is removed, the surface returns to its original condition, with no scarring, no weld pool, no coating breach.

This matters offshore because every penetration or weld point is a potential entry point for corrosion. A steel structure that has never been welded on has one less variable to inspect, coat and monitor over its service life. It is a simple mechanical fact with a direct environmental consequence, which we return to later in this article.

How does a magnetic solution differ from welding or bolting?

Welding fuses two pieces of metal using heat, which requires a power source, shielding gas or flux, a qualified welder and, offshore, a hot work permit with a standby fire watch. Bolting requires drilling through the base material, which breaches any coating and introduces a new stress point.

A magnetic solution needs neither. The magnet is placed, the holding force does the work, and the installation is complete. There is no cure time, no cooldown period and no need to isolate hazardous atmospheres before starting. That single difference is what removes most of the environmental cost we describe in the next section.

Key points:

• A magnetic solution uses permanent magnets, usually neodymium, instead of welding, drilling or bolting.
• The V-Mag© series generates enough holding force to secure brackets, cable trays and instrumentation on ferrous steel.
• Non-penetrating installation leaves no drilled holes, weld seams or coating damage on the base structure.
• Removal restores the surface to its original condition, which supports both reuse and clean decommissioning.
• No hot work permit, standby fire watch or cure time is required before the installation is load-ready.
• The absence of welding and drilling is the direct reason magnetic solutions carry a lower environmental cost than traditional methods.

Traditional offshore installation methods carry a high environmental cost because welding and drilling require hot work permits, fuel-burning equipment, consumable materials and standby personnel, all before a single bracket is fitted. Every one of these steps adds emissions, waste or long-term corrosion risk to the project.

We see this cost most clearly on projects where a simple mounting job turns into a multi-day operation once permits, generators, welding consumables and inspection are added to the schedule.

What emissions come from hot work offshore?

Hot work offshore means any activity that introduces an ignition source, most commonly welding, grinding or cutting. Each of these processes burns fuel, either through the welding generator itself or through the vessel or platform power system supporting it, and each produces fumes that must be managed under offshore health and safety rules.

Welding fumes contain metal oxides and, depending on the coating being welded through, can release additional compounds from paint or primer burning off. On an offshore platform or vessel, this means enclosed extraction, respiratory protection and downtime while the area clears. Grinding adds its own airborne particulate, which needs the same extraction and protection measures even though it produces no flame.

None of this is required when the same job is done with a magnetic mount. There is no fume to extract, no particulate to filter and no downtime built into the schedule for air quality to clear before the next task can start. We go into the safety side of removing hot work in The Benefits of No-Welding Magnetic Tie-Offs for Offshore Safety, which pairs directly with the emissions reduction described here.

How does structural penetration increase long-term corrosion risk?

Every weld and every drilled hole breaks the coating system that protects offshore steel from seawater and salt-laden air. Coatings are engineered as a continuous barrier. Once that barrier is interrupted, the surrounding area becomes a point where corrosion can start and spread underneath the coating, often before it is visible from outside.

Repairing this means re-coating, which itself involves surface preparation, primer and topcoat application, most of it done with materials that have their own environmental handling requirements. A structure with fewer penetrations has fewer of these repair cycles over its service life, and each of those cycles removed lowers material use, waste and inspection cost across the asset's lifetime.

Key points:

• Hot work offshore requires permits, standby fire watch and fume extraction before installation can begin.
• Welding fumes contain metal oxides and, depending on coating, additional compounds from burned paint or primer.
• Every weld or drilled hole breaks the coating barrier that protects steel from seawater and salt air.
• Broken coating creates a corrosion starting point that often spreads before it becomes visible.
• Re-coating after a repair adds material use, surface preparation waste and additional inspection cycles.
• Longer hot work windows mean more generator and vessel fuel burned per installation.
• Fewer structural penetrations over an asset's service life directly reduce long-term maintenance and material cost.

Magnetic solutions eliminate hot work emissions by removing welding, cutting and grinding from the installation process entirely. Without an ignition source, there is no fume extraction requirement, no hot work permit and no standby fire watch team on site.

We have seen this shift a project schedule directly: a job that once needed a hot work permit application, a fire watch rota and extraction equipment can, with a magnetic mount, start as soon as the surface is clean and dry.

What happens to a project's emissions profile when welding is removed?

Removing welding removes three emissions sources at once: the welding process itself, the generator or power supply running it, and the extraction or ventilation equipment needed to manage the fumes it produces. On an offshore installation, these three systems often run in parallel for the full duration of the hot work window.

With a magnetic solution, that entire window disappears. The equipment needed is a surface preparation kit and the magnet itself, both of which require no combustion and no extraction. Over a project with multiple mounting points, this adds up to a measurable reduction in on-site fuel use and airborne emissions.

How do magnetic solutions reduce the need for hot work permits and standby fire watch teams?

Offshore hot work permits exist because welding introduces ignition risk in environments where hydrocarbons, coatings or other flammable materials may be present. Issuing a permit typically requires gas testing, isolation of nearby systems, and a dedicated fire watch person for the duration of the work plus a cooldown period afterward.

A magnetic mounting installation introduces no ignition source, so none of these steps apply. The crew installing a V-Mag© bracket does not need a hot work permit, a gas test or a standby fire watch. This removes both the personnel time associated with those roles and the operational risk of managing an ignition source on an active offshore asset.

Key points:

• Magnetic solutions remove welding, cutting and grinding from the installation process.
• No ignition source means no fume extraction system is required during installation.
• Removing hot work also removes the generator load used to power welding equipment.
• Hot work permits require gas testing, isolation and a standby fire watch, none of which apply to a magnetic installation.
• Crews can begin work as soon as the surface is prepared, without a permit application process.
• Fewer parallel systems running during installation lowers on-site fuel use per project.

Non-penetrating installation protects coating integrity because the surface is never drilled or welded, so the corrosion barrier stays continuous. A continuous coating system is significantly less likely to develop the localized corrosion that leads to structural leaks or steel section loss over time.

On offshore assets, where inspection access is limited and repair costs rise with every meter below deck or below the waterline, keeping the coating intact is one of the most direct ways to manage long-term environmental risk.

How does welding damage corrosion coating on offshore steel structures?

Welding generates heat far in excess of what most coating systems can tolerate. The heat-affected zone around a weld burns off the coating, and the weld itself leaves bare, unprotected steel that must be re-coated after the fact, usually under field conditions that are harder to control than the original application.

If that re-coating is incomplete, or if the heat-affected zone extends further than the visible repair area, a corrosion cell can form at the boundary between old and new coating. This is a known failure mode on retrofitted offshore structures, and it is one that simply does not occur when no welding takes place.

How does a non-penetrating magnet mount help maintain ISO 14001 compliance?

ISO 14001 asks an organization to identify and control the environmental impacts of its operations, including the materials and processes used during installation and maintenance work. A mounting method that avoids welding fumes, coating damage and additional waste streams is easier to document and control under an ISO 14001 environmental management system than one that introduces all three.

We hold ISO 14001, ISO 9001 and ISO 45001 certification through Bureau Veritas, and our own environmental management approach is built around the same principle we apply to our products: reduce the number of processes that create waste, emissions or long-term risk in the first place.

Key points:

• A continuous, unbroken coating system is the main defense against corrosion on offshore steel.
• Welding heat damages the coating around the weld and leaves bare steel that must be re-coated.
• Incomplete re-coating after a weld repair can create a new corrosion cell at the repair boundary.
• Non-penetrating installation avoids this failure mode because the coating is never broken in the first place.
• ISO 14001 requires documented control of the environmental impacts from installation processes.
• Removing welding, drilling and their waste streams simplifies environmental management documentation.

Magnetic solutions reduce vessel days because installation happens in minutes instead of the hours a welded connection requires, once permits, setup and cooldown are included. Fewer vessel days mean less fuel burned per project and a shorter window of exposure for the crew on site.

Vessel day cost is one of the largest line items on any offshore project, and it is also one of the most direct proxies for fuel use and emissions, since every extra day on site means the vessel or platform's power systems keep running.

How many vessel days can a magnetic installation save compared to welding?

A welded bracket installation offshore typically includes permit approval, gas testing, hot work setup, the weld itself, a cooldown period and a coating touch-up before sign-off. Depending on access and weather windows, this can extend a single mounting job across an entire shift or more.

A magnetic installation compresses this to surface preparation, magnet placement and load verification, work that is typically measured in minutes rather than the shift or more a welded connection requires. Multiplied across a project with dozens or hundreds of mounting points, this difference compounds quickly.

How does faster installation reduce fuel consumption and CO2 per project?

Every day a vessel or platform team spends on an installation task is a day of generator run time, crew transport and, on larger projects, standby support vessels. Shortening the installation window shortens all three simultaneously, without requiring any change to the vessel's own fuel efficiency or engine specification.

Fuel burned scales with time on task, which makes this one of the easier savings to calculate in offshore project planning. A method that removes hours from each installation point removes the fuel associated with those hours, project by project, point by point. Across a full retrofit or new-build scope, that arithmetic applies to every mounting location on the schedule, not just a single bracket. We break down the time savings in more detail in How Magnetic Solutions Help Offshore Projects Save Time, which this fuel and emissions case builds directly on.

Key points:

• Welded installations include permit approval, gas testing, cooldown and coating touch-up before sign-off.
• Magnetic installations skip these steps, reducing a job to surface preparation, placement and load verification.
• Vessel day cost is one of the clearest available proxies for fuel use and emissions offshore.
• Faster installation shortens generator run time, crew transport needs and standby vessel requirements.
• Time saved per mounting point compounds across projects with large numbers of installation points.
• Fuel consumption scales directly with time on task, so shorter installation windows reduce fuel burned.

Magnetic installation generates far less waste than welding or bolting because it uses no welding rods, no shielding gas, no grinding discs and no drilling swarf. The main consumable is a surface preparation wipe, compared to an entire supply chain of materials behind a single welded connection.

Waste offshore is not just an environmental line item. Every consumable used has to be shipped out, stored, tracked and, if unused, shipped back, and every waste stream generated has to be segregated and shipped ashore for disposal under the platform or vessel's waste management plan. Fewer consumables and less waste means less of this logistics chain running in the background of the project.

The table below sets out the difference directly, based on what each method requires per installation point.

What consumables does welding require that magnetic mounting eliminates?

A single welded connection typically draws on welding rods or wire, shielding gas, grinding discs for surface preparation and finishing, and often a fresh coating kit for the repair afterward. Bolting adds drill bits, fasteners rated for the environment, and sealant to manage the new penetration point.

A magnetic installation replaces this entire list with a clean surface and the magnet itself. There is no rod, no gas cylinder, no disc and no drill bit consumed per mounting point, which also means none of the packaging, transport or disposal associated with those items offshore.

How much waste does a magnetic installation generate compared to welding or bolting?

Welding produces slag and spent electrode waste. Grinding and drilling produce metal swarf, some of which ends up overboard or in deck drainage if not carefully managed. Both processes also produce damaged coating material that must be removed before re-coating can begin.

A magnetic installation produces none of these waste streams. The only material used is a surface preparation wipe, and the magnet itself is not consumed. It stays in place, or it is removed intact and relocated to the next project.

Key points:

• Welding consumes rods, shielding gas and grinding discs per installation point.
• Bolting adds drill bits, fasteners and sealant to manage the new penetration.
• Magnetic installation replaces this entire consumable list with a surface preparation wipe.
• Slag, spent electrodes and metal swarf are common waste products of welding and drilling.
• Damaged coating material must also be removed and disposed of before re-coating.
• A magnetic solution produces none of these waste streams, since the magnet itself is not consumed.

Reusable magnets support a circular approach because the same unit can be removed intact and relocated to a new project, instead of being cut away and scrapped at the end of an asset's service life. This reduces both the steel waste generated at decommissioning and the number of new units manufactured for the next project.

We build the V-Mag© series with this reuse in mind, which is part of why it competes directly with welding on total lifecycle cost, not just installation cost.

Can magnetic solutions be relocated and reused across projects?

Yes. Because the magnet is never welded or bolted in place, it can be released from one surface and repositioned on another without cutting, grinding or leaving material behind. A bracket used on a wind turbine tower during construction can be removed at project handover and redeployed on the next tower, or a different asset entirely.

This is not possible with a welded fixing, which is permanently fused to the structure it was installed on and has no value beyond that single application.

How does removable mounting reduce steel waste at decommissioning?

Decommissioning a welded fixture means cutting it away from the parent structure, which produces both a steel offcut and a section of coating and base material damaged in the process. At scale, across a platform or turbine array being decommissioned, this adds up to a significant volume of mixed steel waste that must be handled and disposed of.

A magnetic fixture is released rather than cut. The base structure is returned to its original state, the fixture itself is recovered whole, and neither generates the cutting waste associated with a welded or bolted alternative.

Key points:

• A magnetic fixture can be released and relocated to a new project without cutting or grinding.
• Welded fixtures are permanently fused and have no reuse value beyond their original installation.
• Decommissioning a welded fitting produces steel offcuts and damaged coating material as waste.
• Releasing a magnetic fixture returns the base structure to its original condition.
• Reuse across projects reduces the number of new units that need to be manufactured.
• Lower decommissioning waste is a direct, measurable outcome of using a removable fixing method.

Magnetic solutions are already reducing environmental impact across wind energy, marine, oil and gas, and telecom installations, wherever equipment needs to be mounted on steel without welding or drilling. Each sector uses the same underlying principle for a different application.

How are magnetic solutions used in wind energy and marine installations?

In wind energy, we use magnetic brackets and anchor points during tower construction, commissioning and maintenance, for everything from cable routing to temporary tie-off points. Because turbine towers are often accessed under time pressure during narrow weather windows, removing welding from these tasks directly shortens the time technicians spend working at height offshore.

In marine applications, magnetic mounting is used on vessels and fixed marine structures for equipment brackets, cable management and temporary fittings, where hull or structural penetration is either restricted by class rules or simply undesirable given the maintenance burden it creates.

How are magnetic solutions used in oil & gas and telecom infrastructure?

On oil and gas platforms, hot work restrictions are often at their strictest, given the proximity of hydrocarbons. Magnetic solutions let teams install brackets, instrumentation mounts and cable management without triggering a hot work permit process, which can otherwise be the single largest source of schedule delay on a platform retrofit.

In telecom infrastructure, much of the work involves mounting antennas, cabinets and cable trays onto existing steel structures, onshore and offshore alike. A non-penetrating magnetic bracket avoids drilling into structures that may already be at capacity for permitted penetrations, or where the asset owner restricts further modification.

Key points:

• Wind energy projects use magnetic anchor points and brackets during construction, commissioning and maintenance.
• Removing welding from tower work reduces time spent at height during narrow offshore weather windows.
• Marine applications use magnetic mounting where hull penetration is restricted or undesirable.
• Oil and gas platforms benefit most from avoiding hot work permits in hydrocarbon-restricted zones.
• Telecom infrastructure uses non-penetrating brackets where structures are near their permitted penetration limit.
• The same magnetic principle applies across sectors, adapted to each industry's access and safety constraints.

Magnetic solutions perform reliably in extreme offshore conditions because the V-Mag© series is built for corrosion resistance and permanent or semi-permanent holding force in salt, wind and temperature extremes. Fewer maintenance visits over the asset's life translate directly into fewer emissions from repeat vessel trips.

How corrosion-resistant are magnetic solutions in saltwater environments?

Offshore steel structures are under constant exposure to salt-laden air and, in marine and platform applications, direct seawater contact. A mounting solution has to hold its rated force through this exposure without corroding at the contact point or degrading the surface it is mounted to.

The V-Mag© series is corrosion resistant by design, which is part of why we can rate it for permanent or semi-permanent installation offshore rather than treating it as a temporary fix that needs regular replacement. One documented case describes a V-Mag© 340 installation that held through multiple seasons of storms, heat and freezing conditions without moving.

How do fewer maintenance visits reduce emissions over an asset's lifecycle?

Every maintenance visit to an offshore asset involves a vessel trip, a crew transfer, and often a support vessel or helicopter depending on distance and weather. A fixing that needs to be re-torqued, re-coated or replaced on a regular schedule adds these trips to the asset's maintenance calendar for as long as it remains in service.

A fixing rated for long-term exposure without degradation removes that recurring trip from the schedule. Over a twenty-year asset life, the difference between an annual maintenance visit and no visit at all for a given fixing point is not a small number once multiplied across every mounting point on the structure.

This is also where extreme conditions performance and environmental impact overlap directly. A fixing that fails under storm loading or salt exposure does not just create a safety issue, it creates an unplanned vessel mobilization to repair or replace it, often at short notice and outside the normal maintenance calendar. Unplanned trips are typically less fuel-efficient than scheduled ones, since they cannot be combined with other work on the same visit. We cover the operational side of this in How Magnetic Solutions Enhance Offshore Efficiency in Extreme Conditions and Why Extreme Conditions Challenge Offshore Efficiency.

Key points:

• Offshore mounting solutions must hold rated force through constant salt and moisture exposure.
• The V-Mag© series is corrosion resistant and rated for permanent or semi-permanent offshore use.
• A documented case shows a V-Mag© 340 installation holding through multiple storm seasons without movement.
• Every maintenance visit to an offshore asset involves a vessel trip and crew transfer.
• Fixings that avoid regular re-torquing or replacement remove recurring trips from the maintenance calendar.
• Over a multi-decade asset life, fewer maintenance visits per fixing point add up to a measurable emissions reduction.

ISO 14001, ISO 9001 and ISO 45001 certification, held by the supplier and verified by an independent body such as Bureau Veritas, confirm that a magnetic solutions provider manages environmental impact, quality and safety under a documented system, not just as a product claim.

What does ISO 14001 certification mean for a magnetic solutions supplier?

ISO 14001 is the international standard for environmental management systems. It requires an organization to identify the environmental aspects of its own operations, set objectives to reduce negative impact, and demonstrate ongoing compliance through audit.

For a magnetic solutions supplier, this covers everything from how products are manufactured to how installation guidance is documented for clients. We hold ISO 14001 certification through Bureau Veritas, which means our environmental management approach is independently audited, not self-declared.

How do ISO 9001 and ISO 45001 support environmental compliance alongside quality and safety?

ISO 9001 governs quality management, ensuring products perform consistently to specification project after project. ISO 45001 governs occupational health and safety management, which is directly relevant offshore given the hot work, working-at-height and manual handling risks that magnetic solutions are often used to reduce.

Together with ISO 14001, these three certifications describe a supplier whose environmental performance is tied to the same management discipline as its quality and safety performance, rather than treated as a separate marketing claim.

Key points:

• ISO 14001 is the international standard for environmental management systems, verified by independent audit.
• ISO 9001 governs consistent product quality across projects.
• ISO 45001 governs occupational health and safety, relevant to the hot work and working-at-height risks magnets help reduce.
• We hold all three certifications through Bureau Veritas.
• Independent certification separates a documented environmental management system from an unverified marketing claim.
• Buyers evaluating environmental credibility should ask for certification evidence, not product descriptions alone.

Choosing the right magnetic solution for an environmentally focused offshore project starts with matching holding force and surface condition to the load, then checking corrosion rating, install and removal method, and whether the fixture needs to be reused elsewhere afterward.

What technical factors determine which magnetic solution fits a given project?

The base surface material and thickness determine available holding force, since magnetic attraction depends on the steel's magnetic permeability and the air gap between magnet and surface. Load direction matters too: a static vertical load behaves differently under a magnetic mount than a dynamic or shock load, which is why our V-Mag© 70 and V-Mag© 340 are rated separately for different force requirements.

Beyond holding force, the environment matters just as much: temperature range, exposure to seawater or chemicals, and whether the installation is permanent, semi-permanent or temporary. Fall protection anchor points, such as our P-Tool©, carry additional certification requirements given their safety function, which a general-purpose bracket would not need to meet.

When should magnetic solutions be combined with other Engiso products on the same installation?

Larger projects rarely need just one product. A cable management task might combine V-Mag© brackets with a TBR Bracket© interface plate where a non-standard fitting needs to sit between the magnet and the equipment being mounted. A maintenance job involving both fall protection and flange work might combine the P-Tool© with our flange alignment tools on the same platform visit.

We work through this combination with clients directly, since the right mix depends on the specific structure, access constraints and safety requirements of each project, not a fixed template applied regardless of site conditions. For a general walkthrough of selection criteria beyond the environmental factors covered here, see How to Choose the Right Magnetic Solution for Offshore Operations.

Key points:

• Holding force depends on the base material's magnetic permeability and the air gap at installation.
• Load direction, whether static, dynamic or shock, changes which magnetic product rating is appropriate.
• Environmental exposure, including temperature range and seawater contact, determines corrosion rating requirements.
• Safety-critical applications like fall protection anchor points carry additional certification needs.
• Larger projects often combine several magnetic products, such as brackets with interface plates.
• The right combination depends on site-specific conditions, not a single standard configuration.
