We understand the shipyards building process and the end user’s operation. Weka provides cooling solutions and other marine products by engineering and integrating tailored solutions in order to achieve optimal product performance while maintaining the right integral cost price. Our ‘first time right’ project approach is valued by our partners because our excellent technical coordination during the engineering, production or commissioning processes, relieves the shipyard during their building process.
