Zero-Emission Heat Recovery System wins Maritime Innovation Award

November 9, 2017


KOTUG International BV has won the Maritime Innovation Award 2017 at the annual Maritime Award Gala. On 6 November 2017 the award was handed over by the expert Jury for the new cost-effective and sustainable system to store and regenerate heat on tugboats, the Zero-Emission Heat Recovery System.

The Heat Recovery System makes the tugboat operation more energy efficient and therefore more green. A tugboat produces heat during operation and  it requires energy during stand-by periods. Kotug has developed a way to re-cycle the cool water heat from the main engines and store the heat in a smart latent heat buffer. The required energy is needed for the climate control and to keep the engines warm. It  is usually derived from electrical shore power at a considerable cost.

“We are very proud with this acknowledgement by the expert jury of the Maritime Awards. It is a great encouragement for us to continue to develop and to innovate. The use of Phase Change Material (PCM) technology is new in the maritime industry and has great potential not only for tugboats, but for every type of vessel, as it can be tailored to different spaces and user profiles. KOTUG is looking into more applications for temperature control purposes.”, said Koos Smoor, Manager Fleet Performance & Innovation at KOTUG.

The Heat Recycling System has been installed on the ZP Bison a tugboat of Kotug Smit Towage, and is working properly. The new system is an eco-friendly and cost-effective solution. It reduces shore power consumption with 50%, thus cutting CO2 emissions by half. Which is approx. 50.000kWhr less on the meter every year. These savings are a major achievement with regards to the reduction of the operational cost and the emission reduction.

Ard-Jan Kooren, CEO Kotug International: ”We see beauty in solutions that combine the golden triangle of state-of-the-art technology, sustainability and cost reductions. This innovation is an answer to market demand as well as environmental requirements and actually reduces costs as well.”

The goal of the Maritime Award is to raise awareness of the innovative power generated and radiated by the maritime and offshore supply industry. The prize also aims to stimulate innovative developments within the maritime cluster. Kotug’s Zero-Emission Heat Recovery System, answers these questions with its economical, technical and environmental benefits.
