Main presentation

Founded in 2020 and based in Saint Nazaire, ALKA MARINE specialises in services for marine renewables projects. It owns a 37m tug and anchor-lifting vessel - ALMA KAPPA - sailing under the flag of France. It also owns a hybrid-propulsion survey and research vessel - ALKA BULLDOG.
With its integrated solutions, ALKA MARINE aims to contribute to the development of France's marine renewables industry. It applies exacting standards for safety, quality and respect for the environment. To achieve this, the company draws on its founders' expertise: ALMA SHIPPING, a French fleet owner operating 12 vessels in West Africa and KAPPA OFFSHORE SOLUTIONS, a design and engineering office specialising in marine seismic data acquisition.
