CURRICULUM VITAE

Mikael Mäkinen was born in Finland and began his career as a naval architect, spending 20 years leading a range of projects for Wärtsilä before moving to Cargotec. Most recently he was President of Cargotec’s MacGregor business, and has lived and worked in many countries, including seven years in Singapore. “Mikael joins us at an exciting time and I am delighted he will lead our Marine business into the future. He brings with him an impressive set of credentials and extensive experience of our industry, both as a customer and a supplier of marine technology,” said Lawrie Haynes, President of Marine and Industrial Power Systems.

MIKAEL MÄKINEN, PRESIDENT – MARINE, ROLLS-ROYCE INNOVATING FOR TOMORROW’S NEEDS As the new President of the Rolls-Royce Marine business, I am proud to be part of a company that leads from the front, providing a world-leading range of marine systems and equipment – and which is continuing to evolve to help our customers meet new challenges

As part of this investment the Promas Lite system will be installed on four Star-class ropax vessels. Finnlines is one of the largest North-European shipping companies operating mainly in the Baltic and the North Sea and is part of the Grimaldi Group. The experience gained over three years of working on a series of reblading projects for ferries operating in the Mediterranean, also for the Grimaldi Group, meant that the fuel saving benefits were well documented and led to this latest award.
