Transport and logistics
Managing critical infrastructure and preparing for the energy future
The transport and logistics sector is on the road to a better, cleaner Britain. Fuelled by the government’s transport decarbonisation plan, as the industry is committed to reaching Net-Zero by 2050.
Transport currently represents roughly a quarter of global CO2 emissions from energy, of which 60% is from heavy-duty transport – trucking, shipping, and aviation. While the future of surface transport appears to be electric, decarbonisation of long-distance shipping and aviation will likely require low-emissions liquid fuels from bio or synthetic sources.
At the same time operators are fighting to maintain their hard-won reputation in a competitive market while ensuring capacity for growth and expansion.
As your trusted environmental partner, we can work with you to ensure your critical assets remain compliant through the energy transition and beyond so you can focus on your unique business strategy.
Our services to the transport and logistics sector across road, rail, air and water
Take a look at our full range of services in our interactive graphic below from audit, maintenance, repair and response across all your critical assets and fuel infrastructure.
Road transport and logistics organisations are currently at a crossroads of deciding whether to move to the erratic HVO market or electric and hydrogen fuelling which requires larger up-front costs. Alternatively, road operators could stick with diesel and take the hit on higher costs.
What all these energy types have in common is a requirement to maintain infrastructure and critical assets compliantly and efficiently to reduce the risk of environmental damage and operational downtime.
As passenger rail continues to occupy largely electrified routes, freight operators, who utilise a mix of electric and diesel, are looking at alternative fuel options such as hydrogen which in certain circumstances can be a relatively simple switch.
Whether diesel or hydrogen the requirement to maintain infrastructure and assets compliantly and efficiently is critical to reduce the risk of environmental damage and operational downtime.
What the law says
A pollution incident as a result of a poorly maintained asset or inadequate containment is a strict liability offence.
The Regulators and Courts view failure to adhere to relevant standards and good practice, particularly in relation to a robust maintenance and inspection schedule, as not enforcing ‘proper systems for avoiding commission of the offence.’
Failure to adhere to standards and good practice guidance is considered an 'aggravating factor' in considering enforcement action and can invalidate insurance.
We can help your organisation to remain compliant, avoid environmental penalties, liabilities, reduce operational downtime and protect your hard-won reputation.
Maintaining your critical assets compliantly can reduce your culpability level from reckless or deliberate to negligent or low / no culpability in the event of an incident.
Regular storage tank inspections and maintenance are essential to minimise the risk of faults, leaks, contents contamination, and pollution. From install to surveys, fuel polishing, uplift and decommissioning, our tank services meticulously clean and maintain assets of any material and capacity, even in confined spaces or inaccessible locations.
Using the latest high-pressure or ultrasonic technology, our skilled engineers and specialist welders test for leaks and structural concerns, repair faulty tanks, and provide detailed follow-up documentation.
- Onsite visits to define requirements and assess underground, ground level, or above ground systems
- Remote inspection, cleaning and diagnostic services using ultra-sensitive ATEX Zone 1 AdlerViewTM cameras
- Leading-edge non-destructive testing (NDT) and analysis to identify corrosion, weaknesses, and welding defects
- Complete follow-up reports and targeted remedial work
- Compliant with EEMUA Level 2, API and NDT standards
Cleaning and purging
We clean and purge all types of storage tanks, from retail forecourt containers to major refinery and military holding systems.
- Proven man-entry and non-man-entry techniques, including gamma jetting, 360 cleaning heads, and state-of-the-art robotic systems
- Suitable for changes of stored product, contamination, deterioration, decommissioning, transportation, or standard upkeep
- Delivered by engineers accredited in water jetting, ultra-high-pressure jetting, shot blasting, and confined space entry
We monitor and repair all varieties of above and below ground tanks and actively reduce the risk of asset failure and environmental incidents. Our tank lining technology provides a cost-effective alternative to tank replacement extending the life of your assets. Tank lining offers total resistance to:
- Ethanol-based fuels
- Wide range of chemicals
Fuel uplift and transfer
Our nationwide network of tankers, leading-edge equipment, and trained specialists is the UK’s largest, delivering fuel uplifts, transfers, and crossover management when and where you need them. We uplift fuel from storage tanks above or underground, matching every site access and volume requirement with a fleet that runs from vans to articulated tankers.
Whether you’re decommissioning a single tank or full site, we work with you to plan the process from initial environmental audit to final site sign-off.
Our DSEAR-trained engineers prepare tanks and pipework by purging them of gas and liquid, regulating flammable vapours and controlling the risk of leaks, fires, and explosions.
- CompEx electricians isolate electrical distribution equipment and prepare potentially volatile structures for removal
- Cutting-edge cleaning techniques remove residual fuel from containers, lines, separators, and dispensers, minimising contamination hazards at every step
With the site clear and compliant, our complex civils teams step in to begin excavation, working
above and below ground to clear earth, pipe networks, tanks and buildings.
Once the physical assets are extracted, targeted remediation work actively minimises contamination. Once compliant the site can be formally signed off ready for onward development.
A secondary containment (or bund) confines hazardous spills in the event of an accidental release or tank breach. Our highly skilled operators ensure your compliance with Ciria C753. We work across the full range of systems – including fuel, oil, diesel, chemical, and gas – to ensure your bunds are lined, cleaned, audited, and maintained to protect against environmental damage.
Our bund construction services use quality materials, advanced protective coatings, and reliable glass-reinforced plastic (GRP) linings to offer lasting assurance against pollution incidents.
Whether you’re surrounding fuel, oil, diesel, chemicals, or gas tanks, our experienced engineering team make sure you meet all relevant storage regulations including Ciria C753 and create a containment structure that proactively prevents hazardous spills and costly tank replacements.
A bund audit highlights structural damage, lining system defects, or pollution hazards before a spill event causes environmental harm and possible financial penalties.
- Trained professionals survey and monitor containment structures
- Services to support any type of tank
- Identifies current or emerging threats, compliance issues, and occupational H&S risks
Regular cleaning is key to an effective bund maintenance programme, ensuring that your secondary containment system is structurally sound and free of contaminants.
- Powerful vacuums extract water or leaked tank contents
- Jet washers achieve a complete clean across the entire structure
- Suitable for confined, inaccessible spaces
Because many bunds were constructed more than 80 years ago from porous brick or concrete, a high number need regular reinforcement to perform at their best.
- Exclusive polyurea AdlerCoatTM works in a single application
- The UK’s most durable and hard-wearing bund lining
- Resistant to hazardous substances, including fuel and chemicals
Adler and Allan is the UK’s top separator servicing and maintenance provider, helping your business remain compliant with regulations as well as safeguarding against pollution, flooding, and fines.
The onus is on operators to demonstrate compliance with regulation, current standards, and good practice to reduce the risk of a pollution incident and any subsequent enforcement action.
BS EN 858-2:2003 and PPG 3* highlight that separators should:
- Be fitted with an automatic warning device/high level alarm
- Be serviced and maintained as a minimum on a 6 monthly basis
- Be subject to a maximum interval of a 5 yearly integrity test
- Have full service and maintenance records available for inspection
