Marine Technical Limits (MTL) designs, manufactures and configures plant and equipment specifically to support efficient tank inspections, and repairs, whilst on-station and in production.
Using our equipment and systems, you will have confidence that safety is being managed to a superior standard while also maximising the efficiency and quality of on-station inspections and repairs.
Our Safe System of Work is aptly named as it’s a fully integrated power distribution and ventilation system with inbuilt fire and gas detection, dampers and automatic shutdown. The executive automatic shutdown makes the system safer, as it does not rely on communication and human action. To meet project needs, we have developed a range of Zone 1 and Zone 2 power and ventilation equipment which can support the full range of inspection and repair activities on all sizes of FPSOs and FSUs.

The Safe System of Work is aptly named. It is a fully integrated power distribution and ventilation system with inbuilt fire and gas detection, dampers and automatic shutdown. The executive automatic shutdown makes the system safer, as it does not rely on communication/human action.
To meet project needs, MTL have developed a range of Zone 1 and Zone 2 power and ventilation equipment which can support the full range of inspection and repair activities on all sizes of FPSO’s / FSU’s: ventilation supplies from 9,000m3/hr to 108,000 m3/hr and power supply provision to support a single hotwork site or up to 12 hotwork sites in a tank/space. In all equipment configurations, the ventilation and hotwork power supplies are automatically shutdown if an unsafe condition occurs.
The logic conditions, equipment status and alarms produced by the Safe System of Work can be relayed to the installation Central Control Room (CCR) via Wifi or wired ethernet.
In order to free up a bed space and maximise productivity during a repair, MTL have developed a solution that replaces the additional communications control room person. This system could essentially be described as an electronically relayed T-card system, with a remote display screen in the CCR.
At the tank entrance there is a simple entry switchboard system which also provides a local display of who is inside the confined space. This entry board contains a PLC which relays the entry status signals to the CCR using wired or wireless ethernet.
Each time a switch is moved on the entry board, it is automatically relayed to the display board which shows who is in the tank and tallies the head count. The display board has battery backup so that in the event of power failure, the last screen shot is still displayed. The system can also be adapted to operate using swipe cards / proximity tokens.
The selection of the most suitable access method for executing repairs at height is dependent on the quantity of work to be carried out, the resource pool available and the nature of the tasks. Whilst it may be suitable to carry out some tasks using only rope access, more difficult scopes are made more efficient if stable work platforms can be provided. MTL have developed work platform designs in steel, GRP and using scaffold for a wide range of tank workscopes with great success.
The extent of cleaning required prior to executing an inspection or repair scope will vary depending on the condition of the space and the nature of the work to be carried out. MTL are experienced in defining cleaning requirements appropriately and where necessary can project manage and oversee bulk demucking, hotwashing and pumping of residual fluids in tanks spaces. We hold hotwashing and pumping kit in stock and we have a thorough understanding of how to run bulk demucking scopes safely and efficiently.
For MTL managed repair projects, MTL supply all of the necessary equipment to execute the works offshore: welding and cutting plant, hand tools, construction aids, rigging equipment, welding consumables, welding gas, compressed air distribution, power distribution and extension cables. We also carry a stock of Classification Society approved ship repair plate in a range of sizes to suit the most likely urgent repair scopes.
When carrying out coating repairs MTL strive to ensure that the best quality repair is achieved. Every effort is taken to ensure that the surface is prepared to a high standard to ensure that coating repairs adhere properly and last. Our dehumidification system enables us to achieve the optimum environment for carrying out coating repairs while on station.
