In 2024, the Safeen Group introduced the Bu Tinah, the world’s most powerful electric tugboat, into permanent service at Khalifa Port in Abu Dhabi, UAE. Built by Damen Shipyards, the electric vessel represents the next generation of sustainable harbour tugs and is a testament to the Safeen Group’s commitment to decarbonising maritime operations in the region. ComAp was honoured to provide the advanced AC/DC Power Management System (PMS) for this pioneering vessel, which efficiently manages onboard power from both battery and gen-set sources.

The Bu Tinah features a custom Damen design and a top speed of 12 knots. Onboard propulsion is provided by two Ramme TW 1400r_L electric engines, delivering a combined 3,700 bkW at 500 rpm. These are powered by a 2,782 kWh battery system, supported by two Caterpillar C32TA gen-sets producing 1,175 kVA at 690 V and 60 Hz. The tug is designed for full-electric operation, with future integration of shore charging infrastructure planned.

This advanced hybrid-electric configuration, controlled by ComAp’s PMS, enables smooth load management and blackout prevention, while optimising energy source prioritisation and heavy consumer coordination. The Bu Tinah delivers an impressive 78.2 tonnes of bollard pull, officially certifying the vessel as the most powerful electric tugboat in the world by Guinness World Records™.

In addition to its record-breaking performance, the Bu Tinah is also highly significant in the region as the first vessel of its kind, setting new standards for sustainable port operations in a region that has historically been dominated by conventional propulsion. With zero emissions from “tank to propeller,” the Bu Tinah highlights a clear move towards more sustainable and efficient port infrastructure in the Middle East.

ComAp’s hybrid PMS solution ensures full control over the Bu Tinah’s complex power system, allowing seamless transitions between energy sources and reducing dependence on fossil fuels. Furthermore, the system provides heavy consumer management, DC voltage matching, and precise control over the battery and gen-sets, as well as the soon-to-be-installed shore power connection.
