About

Maersk Line is aiming at a 60% reduction of CO2 emissions per moved container in 2020, relative to 2007 standards. A state-of-the-art waste heat recovery system can recover up to 8% of the main engine brake power, but is not able to recover the energy in the jacket water cooling system and lubricant oil system. An organic Rankine cycle (ORC) can convert the low temperature heat of these heat sources into electric power producing the equivalent to about 5% of the main engine brake power.

The PilotORC project aims at evaluating the prospect of using an ORC unit for maritime applications. Endurance tests will be performed of an ORC unit recovering heat from the main engine jacket water cooling system on one of Maersk’s container vessels. The results of the tests will be used to further validate and develop the simulation tools at DTU. Research will be carried out on methods for the design optimization and control of ORC units installed on ships. Moreover, models will be developed for estimation of thermophysical properties of novel working fluids suitable for maritime applications. The potentials for introducing the ORC technology for retrofitting purposes as well as for new-buildings will be addressed.

PILOTORC
Arnold Maersk at Lindø shipyard in 2003, by mid - February 2016 the ORC unit will be installed in this vessel.
