ajor investement in hybrid propulsion technology by the world’s two largest enginebuilders underline the key role these technologies will play in meeting today’s requirements for low emissions and high efficiency. In June, MAN Diesel & Turbo announced its intention to acquire a 40 per cent holding in Canadian hybrid specialist Aspin Kemp and Associates (AKA). The investment came about as part of MAN Diesel & Turbo’s strategic development programme, ‘Basecamp 3000+’, launched in 2016. As part of this programme, the company announced strategic acquisitions and partnerships to expand its product range with respect to the global trends of decarbonisation and digitalisation. The move toward hybrid technology is seen as a key plank of this strategy, said MAN chief executive Dr Uwe Lauber. “The partnership with AKA is a key element in our strategy to strengthen our role as technological forerunner in the field of marine propulsion,” he said. “AKA’s specialised expertise links battery storage systems and marine engines. The new co-operation marks an important step on the way to further establishing ourselves as a principal system supplier for energy management on board ships.” Energy management systems (EMSs)

provide fully automatic control and optimise the power distribution of drive components of ships. On ships with hybrid drives, electric motors and battery storage systems are employed alongside diesel and multi-fuel engines. The battery system is recharged with surplus energy from the engine, enabling the engine to be operated in its optimum load range at all times. Any load peaks can be quickly and efficiently covered by the electrical storage system. AKA’s collaboration with key industry partners has allowed it to develop and continuously improve technology for power, propulsion, and drilling applications in the offshore oil and gas and marine sectors, which the company will build on through this new partnership. “AKA is a
