Engineering & Maintenance

Marlin’s highly trained technical engineers are experienced in assembly, installation, commissioning, servicing, overhaul and repair of a comprehensive range of systems, and equipment. Working with leading international companies as well as the MOD, our processes are thorough, across the entire business, from assessment and diagnosis, through to delivery and certification.

Marlin has dedicated engineering workshops across the UK serviced by overhead cranes, and equipped with sonic baths, vapour blasting and a suite of testing machinery.

Engine Systems & Pipework

Marlin undertakes complete systems and pipe work flushing and passivation onboard vessels. This process is used to remove contaminants, debris, and residue. Flushing and passivation are critical for maintaining the performance and reliability of various systems, including:

Flushing & Passivation

Regular maintenance, including flushing and passivation, helps prevent corrosion, improve efficiency, and prolong the service life of onboard equipment and pipelines, ensuring safe and smooth operation at sea.

Methods of flushing and passivation Marlin undertake:

Air Coolers

Air coolers cool the air that a ship’s engine needs during combustion, so the cooler the air, the more efficient the combustion. A clean and well-functioning air cooler cools better and ensures your ship’s engine uses less fuel and emits less CO2.

Using a combination of high-volume washing, ultrasonic cleaning, close proximity jetting and rinse cycles, with controlled chemical cleaning, Marlin ensures even the most difficult to reach places are effectively reached and a thorough job is carried out.

As part of our cleaning service, we will fully restore the capacity of your cooler and extend its life by applying a protective coating.

Heat Exchangers & Coolers

The lifespan of a heat exchanger is directly impacted by the build-up of limescale, oil and other lubricants, which all affect how efficiently it does its job.

Whether your system relies on tube or plate heat exchangers, regular, thorough and professional maintenance and cleaning is vital, to avoid expensive breakdowns – both in time and cost.

Plate heat exchangers require particularly careful and experienced handling, as plates need to be individually cleaned, checked for fissures or cracks and fitted with new gaskets, if required.

Duct & Ventilation

Our highly trained technicians will overhaul, clean, and maintain any number of ventilation systems, to keep ducts and vents in optimal working order.

Using powerful extraction fans and mechanical brushing, we ensure that all debris is removed from within the ventilation trunking, reducing the risk of blockages or a decrease in the flow of clean air.

Our technicians are fully trained on assembly, installation, and strip down on a multitude of systems, all with the aim of improving efficiency and reducing unscheduled down-time for you.
