IMTECH DIESEL ELECTRIC SYSTEM

Imtech to supply Rainbow Warrior green systems

Imtech Marine Group is to supply the entire "green" technical infrastructure on board Greenpeace's new flagship Rainbow Warrior III.

As an international environmental organization, Greenpeace wants its new flagship to be the ultimate example of sustainability. The ship is constructed from environmentally friendly materials, and its design is based on an extensive sustainability study. Preliminary tests were carried out at the Delft University of Technology and in a wind tunnel operated by Wolfson Unit Southampton.

Though Rainbow Warrior III will be fully equipped with sails it will have the option in unsuitable weather conditions to switch to diesel-electric propulsion.

Engineering of the energy-efficient electrical propulsion will be among Imtech Marine Group's responsibilities. The system will give considerable energy savings and substantially lower carbon emissions compared to a conventional propulsion system. This technology will only be used when there is not enough wind to sail. The emitted residual heat will be used to heat the water system. The intelligent integration of all electrical and electronic systems on board allows for additional energy savings. An important role has been assigned to the sustainable platform automation and the intelligent energy distribution system, which will be installed by Imtech. In addition, Imtech will provide the ship with the most up-to-date navigation and communications technology.

In the U.S., Imtech Marine Group is involved in the engineering of an ecological tour boat that sails on a combination of solar energy and sustainable electric propulsion.

In another project, Imtech is working with Feadship (a leading designer and builder of luxury yachts) and MTU on a study of the options for green luxury (mega) yachts. This study is supported by SenterNovem (an agency of the Dutch Ministry of Economic Affairs) and the Dutch research institutes TNO and MARIN.

Imtech is also responsible for the engineering and implementation of the electric propulsion on board the futuristic solar cell vessel Solar Planet. On this vessel, thousands of photovoltaic cells to convert sunlight directly into electricity to drive a quiet and clean electric engine that handles propulsion. In 2010, this ship will be used to make the first voyage around the world powered by solar energy.
