Wärtsilä and CBO to partner in Latin America’s first hybrid vessel upgrade project

The technology group Wärtsilä and CBO, one of Brazil’s leading operators of offshore support vessels, have recently signed an agreement to convert a vessel from CBO’s fleet to operate with hybrid propulsion. The ‘CBO Flamengo’ will be the first vessel in Latin America to be fitted with a battery pack for hybrid propulsion, which will improve the vessel’s energy consumption and reduce its carbon footprint. The order with Wärtsilä was placed in October 2020.

The Wärtsilä Hybrid Solution to be installed on the ‘CBO Flamengo’, a platform supply vessel (PSV), complies with the DNV-GL’s ‘Battery Power’ class notation, allowing the ship’s engines to run more efficiently by operating safely with fewer engines at a higher load. The hybrid system will provide redundancy power and reduce intermittent load increases (peak shaving), thereby saving fuel and reducing exhaust emission levels. Furthermore, because the engines will operate for fewer running hours, maintenance requirements and costs will be reduced.

“CBO is always interested in new technologies and innovation is in our DNA. We seek less fossil fuel consumption and this, aligned with our ESG (environmental and social governance) initiatives, makes the decision to install batteries in our vessels a natural path. CBO will offer more efficient operation to our clients, and this will be the first step of more to come. Wärtsilä is a leader in innovation and has extensive know-how in hybrid battery systems for ships, so we are pleased to join forces with Wärtsilä to implement new technologies into CBO’s fleet,” says Marcelo Martins, Technical and Commercial Director at CBO.

“We are proud that a forward-looking company like CBO has selected Wärtsilä as its project partner in supplying this ground-breaking technology for Brazil’s first hybrid vessel. Our strong track-record and depth of experience in developing advanced hybrid solutions were the key reasons for the award of this contract,” says Ian Brouwer, Senior Sales Manager at Wärtsilä Marine Power.

The scope includes the power conversion, project services, the hybrid solution delivery, and commissioning. Delivery of the Wärtsilä equipment is scheduled for April 2021. Installation and integration of the equipment will be handled by CBO.

The marine industry’s first integrated hybrid power module

By combining its competences in marine electrical, automation and engine technologies, Wärtsilä has brought together multiple functions and systems to deliver a single integrated hybrid power module that combines engines, an energy storage system, and power electronics optimised by a unique and highly sophisticated energy management system (EMS).

The EMS functions as the ‘brain’ in the Wärtsilä Hybrid System. It optimises the energy flows between the different power sources, storage, and consumers to achieve the highest efficiency possible.

Thyssenkrupp Marine Systems acquires Oceana Shipyard

Thyssenkrupp Marine Systems – based in Kiel, Germany – has just signed the contract to acquire the Oceana Shipyard (Itajaí / SC) from the company Aliança S.A., which belongs to the Grupo CBO.

The agreement creates the initial basis for the construction of Tamandaré Class frigates for Brazilian Navy, as well a greater growth of the company in the country. The transaction is subject to approval by antitrust authorities and official entry into force of the frigates’ contract, scheduled for mid-2020. The acquisition will be carried out through the Brazilian subsidiary Thyssenkrupp Marine Systems do Brazil.

By agreement, the transaction value will not be disclosed.

“Even in difficult times like these, we continue with determination and remain strongly at our customers side. With Oceana, we have an excellent infrastructure for the construction of the most modern frigate in the country for the Brazilian Navy. The acquisition highlights our commitment to Brazil and will be an important economic factor, especially today. The shipyard also offers us the prospect of taking orders from other customers, not only locally, but also in other South American countries”, says Rolf Wirtz, CEO of Thyssenkrupp Marine Systems.

The Oceana shipyard was created in 2013 to produce high quality and technology offshore support vessels and is ideal for large projects. In the next two years, 800 local workers will be recruited just for the Tamandaré Class project. This means that ships with high national added value can be built in Brazil. The ships are expected to be delivered between 2025 and 2028.

CBO acquires PSV 4,900 and targets opportunities for chartering ‘high-spec’ vessels

In December 2019, the Grupo CBO announced the purchase of the PSV Standard Supporter (4,900 dwt) in international market. The vessel currently operates in North Sea under the management of partner Fletcher Group, whose headquarters are in United Kingdom.

According to the Brazilian company, the CBO Supporter will be available for new opportunities in 2020 in Brazil, in North Sea or in other promising markets.

The vessel, built in Norway in 2009, works with a diesel-electric propulsion system and has as main characteristics: DP2, “clean design”, “comfort class”, “oil recovery class” and “firefighting 1 class” (combat system FIFI-rated external fire protection 1). The PSV, which accommodates up to 25 people, has 1033 square meters of deck area and 10 tons per m² of resistance. According to CBO, the vessel’s 15 tanks are capable of transporting diesel, water, mud, brine, cement, oily water, methanol, and other special products.
