KCC to equip four new ships with Silverstream air lubrication technology

Klaveness Combination Carriers (KCC) on Wednesday (15 November) announced a deal has been agreed to retrofit four additional vessels with the Silverstream® System, the air lubrication technology that reduces fuel consumption and the subsequent CO2 emissions.

The technology will be first installed on CLEANBUs Barracuda and Barramundi, with CABUs Balboa and Baffin due to follow. The vessels will join the already outfitted MV Ballard and upcoming MV Baru, bringing the total number of KCC vessels fitted with Silverstream’s technology to six.

The Silverstream® System utilises a series of air release units (ARUs) located along the flat bottom of the vessel. Oil-free compressors generate pressurised air that is sent through the ARUs, creating a layer of microbubbles that lubricate the hull, thereby reducing the friction between the hull and water. This reduction leads to a decrease in net fuel consumption and the subsequent CO2 emissions.

KCC CEO Engebret Dahm, said: “Improving the energy efficiency of our fleet through proven and reliable technologies is crucial to our commitment of delivering cost-effective decarbonization for our customers. Early performance data from the first installation of the Silverstream solution on MV Ballard in September confirms a fuel consumption reduction in line with our expectations. We look forward to expanding its rollout.”

Silverstream Technologies Founder & CEO Noah Silberschmidt, said: “Our collaboration with KCC goes from strength to strength. They are a great collaboration partner for Silverstream Technologies and we are proud to support them on their journey towards net zero. The wet and dry bulk segment is an important one for Silverstream and we are pleased to be able to demonstrate the savings our Silverstream® System achieves in-service on these efficient combination carriers.”

It is expected the Silverstream solution will reduce emissions by an average of 5-7% on KCC’s vessels. In combination with the other energy efficiency measures underway in the fleet, this figure ranges approximately 15% when compared against performance as newbuilds. In addition to the agreed four vessels, KCC carries options for vessels built 2016-2021 to also equip the technology.

London-based maritime clean technology firm Silverstream Technologies on Tuesday (9 April) said it has successfully completed another retrofit of its air lubrication technology, the Silverstream® System, on a large LNG carrier at Seatrium’s Admiralty Yard in Singapore.

The retrofit, which was on a 174k cbm LNG carrier owned by an oil major, was completed in 30 days reinforcing the role that Silverstream’s technology can play as a near-term decarbonisation solution for existing ships. It is the 11th retrofit of the Silverstream® System that the company has delivered worldwide.

The Silverstream® System releases a carpet of air to reduce the frictional resistance between the hull and the water, reducing average net fuel consumption and GHG emissions by 5-10%. Moreover, in the case of LNGCs, these savings result in increased delivered volumes.

Silverstream has a proven track record of newbuild and retrofit installations and has delivered every one of its 69 in-operation installations on time. By completing the retrofit within 30 days, Silverstream also minimises any impacts on a vessel’s profitability.

Speaking on the announcement, Noah Silberschmidt, Founder & CEO, Silverstream Technologies, said: “This successful retrofit at Seatrium of our technology onboard another LNG carrier is yet further proof of our deep experience in the LNG segment. The market conditions and operational factors unique to LNGCs make them perfectly suited to our air lubrication technology, and we will continue to work with energy majors and our yard partners to ensure smooth installations onboard any vessel that chooses us as an efficiency-boosting option.”

Alvin Gan, Executive Vice President, Repairs and Upgrades, Seatrium Limited, said: "As the premier yard in LNGC repairs, upgrades and conversions, Seatrium is committed to working with our customers and partners to provide turnkey, one-stop solutions in energy efficiency retrofits for LNG carriers. Our collaboration with Silverstream Technologies is successfully delivering another retrofit of their air lubrication technology and further solidifies our position in the industry. By providing comprehensive engineering services through excellent project execution, we aim to continue to lead and play a key role in assisting our customers to achieve their energy efficiency targets."

Methanol

LR: Total cost of ownership a potential barrier for methanol propulsion on passenger ships

Report shows TCO for passenger ships retrofitted with methanol dual-fuel engines to be more than double the cost of blended fuel (Blend B30), HFO and HFO with carbon capture technology.

A new report from Lloyd’s Register (LR), released recently, found that the total cost of ownership (TCO) for passenger ships retrofitted with methanol dual-fuel engines to be more than double the cost of blended fuel (Blend B30), heavy fuel oil (HFO) and HFO with Onboard Carbon Capture and Storage technologies (oCCS).

LR’s Fuel for thought: Methanol for Passenger Ships examined the TCO for operators over a 15-year period and based results on a calculation that 65% of voyage time would be spent in EU waters. 

Overall findings identified in the report, based on analysis by the LR Business Advisory team, show the bunkering price of methanol to be the main commercial barrier for its adoption, with the use of less environmentally friendly fossil based (grey) methanol a more commercially attractive proposition for passenger shipowners than a blend of 50% grey, 25% bio- and 25% e-methanol, even when EU emissions taxes are taken into account.

However, the study highlights that methanol is a technically viable fuel for ship operators looking to reduce the carbon emissions of passenger ship newbuilds, owing to the similar characteristics of methanol to existing fuels. 

Viable retrofit paths have also been taken to the sector, such as the pioneer LR project for the Stena Germanica back in 2015. This technical viability is reflected in the global orderbook with passenger ships ranging from small inland vessels to the largest cruise ships awaiting delivery.

The report also outlined that greater investment is needed in green and bio-methanol production along with improved bunkering infrastructure to increase fuel availability and reduce costs to a commercially viable level.

Natasha Pritchard, VP Strategic Key Accounts (Cruise), Lloyd’s Register, said: “Our latest Fuel for thought report brings some much-needed insights for passenger ship owners evaluating methanol as part of their energy transition pathway.”

“Whilst methanol as marine fuel holds considerable promise as a low carbon solution for passenger ship propulsion, the total cost of ownership (TCO) compared to other fuels may represent an obstacle to its widespread take-up in the segment.”

“It is therefore vital that renewable and low-carbon production of methanol is prioritised in order to drive down these costs.”
