The Oceandiva London is a fully electric event vessel that will sail on the River Thames. Energy is supplied by two lithium battery packs with a total capacity of 2.2 MWh supplied by EST-Floattech.

The energy storage system is one of the cornerstones for the vessel’s CO2-neutral operation. In this way, EST-Floattech is instrumental for the vessel having received the Green Award Foundation’s Gold Certificate with a Platinum Label. This is the highest level of recognition for shipping companies committed to environmental protection, safety and quality. Oceandiva London is also the first vessel of its kind to receive it.

Industry firsts

The groundbreaking vessel, which will enter service this summer, features several industry firsts. What little CO2 the vessel might release, will be balanced by the same amount being absorbed from the atmosphere. The batteries are charged by both green fast charging shore power and onboard solar panels, with a biofuel generator as back up for longer excursions.

The Oceandiva London is a flag bearer of the Net Zero Marine Services (NZMS) programme to decarbonise London’s river.

The new event vessel was designed for the British events company Smart Group by Amsterdam-based company Oceandiva – who operates similar ships in the Netherlands, Germany and Belgium. Working in collaboration with Oceandiva, Smart Group owns, manages and operates the vessel.

The 86-metre-long and 17-metre-wide Oceandiva London – the largest floating event venue on the Thames – offers 2625 m2 of flexible indoor and outdoor space spread across three decks. It can host a range of events, whether static or sailing in the heart of the city.

The vessel was built by VEKA Group of Werkendam, the Netherlands. Electrical system integrator Werkina Werkendam commissioned EST-Floattech for the energy solution. Nesec Fund Management BV from Rotterdam, a specialist maritime financing institution, enabled the project.
