DBI technology
Environmental concerns have become one of the main drivers of change in the maritime industry. Increasing regulatory requirements, the pursuit of emission reductions, and the development of electric and hybrid propulsion systems mean that every kilogram of equipment now has real significance. In response to these challenges, DBI technology was developed – a solution that allows for the replacement of heavy copper cables with lighter aluminum wires.
DBI technology is a solution that offers a range of benefits for manufacturers and owners of vessels – from cost optimization and increased fleet durability in operational conditions to increased cargo capacity. Instead of heavy copper cables that add weight to the fleet, lighter aluminum cables are used, offered as a set with specialized fittings and tools.
Zalety technologii DBI
The solution was designed to reduce and optimize weight, translating into tangible operational benefits—from cost and fuel efficiency optimization to increased vessel payload. The system is DNV-certified, confirming its compliance with rigorous industry standards.
The technology has been comprehensively tested for everyday operating conditions. Its resistance to thermal shock and heating cycles, vibration, and tensile loads, as well as its behavior under short circuit conditions, has been verified. Salt mist resistance, water resistance, and fluctuating temperatures and humidity have also been tested, confirming the system’s reliability even in the most demanding operating environments.
Advantages of DBI Technology:
– Weight reduction and optimization
– Optimizing costs, fuel consumption, and increasing payload capacity.
– Technology tested under conditions encountered during daily use:
- thermal shock,
- vibrations,
- tensile strength,
- heating cycles,
- short circuits,
- salt mist,
- waterproof,
- temperature and humidity
– System with DNV certification
What does the system include?
- Flexible aluminum cable
- MTR copper terminal (cross-sections: DBI 95-12, DBI 120-12, DBI 150-12)
- SH450JCM crimping head (included with a storage case and space for dedicated dies)
- Pompa SVEPT20-520JCM (pakowana w walizkę)
- Hydraulic hose for connecting the pump to the SF30J MTR head.
DBI technology was used by (selected projects):
Olympic Bibby
- The main reason for the trial installation was to gain experience with cables and connections in harsh environments (North Sea), where the vessel had a 3-year contract
Olympic Artemis
- On the Olympic shipping vessel, which has been at sea for 5 years, 3000m of 3×150 EMC VFD was installed in 2015.
5 Shipyard Fjord 1 car ferries
- The conversion of the ships to hybrid propulsion was possible thanks to the installation of 5,000 m of cable for each ferry
Electric Cruise Ferry Shipyard Bröderne AA
- In 2019, 1,400m of cable was installed on the aluminum Electric Cruise Ferry.
