How to decarbonize your ship - battery hybrid + varying engine load

This case study also examines a general cargo ship with an auxiliary engine of 116 kW that is outfitted with a battery to make it a ‘battery hybrid’ while at berth. Again the battery pack powers the ship for several hours while idling or moored and is recharged using the auxiliary engines. This time however, engine load is varied in different loading scenarios to determine the impact of different operational profiles on the business case.

How to decarbonize your ship - general cargo ship with battery hybrid

This case study examines a general cargo ship with an auxiliary engine of 116 kW that is outfitted with a battery to make it a ‘battery hybrid’ while at berth. The battery pack powers the ship for several hours while idling or moored and is recharged using the auxiliary engines. Cost savings generally occur with an average engine load below 50%, but are mostly dependent on engine maintenance costs, spares and consumables as well as total battery pack costs.

How to decarbonize your ship - Large Fishing Trawler

This is a case study on how to decarbonize a fishing trawler - the Jacobus Maria - using shore power, battery hybrid EES and biofuels. 20% CO2 reduction is achieved, half of which stems from the use of biofuels (HVO). The hybrid battery pack is economically not feasible with the assumptions used and the operational profile. The Jacobus Maria has 1 MW installed engine capacity. Total cost would be at least €1M. 10% CO2 reduction can be achieved with approx. €50k.

Inside a Battery Container

The Corvus BOB (Battery On Board) is a standardized, class-approved, modular battery room solution available in 10-foot and 20-foot ISO high-cube container sizes. The complete system comes with battery, monitoring system, HVAC , TR exhaust, plus firefighting and detection system. The plug and play battery room simplifies integration into any system integrator’s power management system on board a ship. The battery cells have passive thermal runaway protection, and are type-approved according to DNV.

Maritime Battery Forum with Syb ten Cate Hoedemaker

During the lunch and learn, current forum Director Syb ten Cate Hoedemaker will exchange knowledge and experience from the usage of batteries within the shipping and offshore industries. You will learn which batteries will suit your vessel, plus discover the costs and payback for different operational modes. Which battery suits your vessel, your needs, your operational profile? This is the key question discussed in this lunch and learn with Maritime Battery Forum.

Get Ready for the Alfa Lift, an Electric-Hybrid Heavy Lift Crane Vessel

The Alfa Lift, a new build heavy lift crane vessel owned by Offshore Heavy Transport, is on track to enter service by early 2022. The vessel features a 3,000 ton main crane, 10,000+ m² smart deck which can be fully submerged to a depth of 15 meters and a electric-hybrid battery system made by Kongsberg.

The Big Friendly Hybrid Giant

The North Sea Giant, a Norwegian offshore construction vessel, is the first DNV class-approved ‘hybrid’ DP3 vessel with three batteries on-board that have a total capacity of 2.034 kWh. The batteries have been installed in an upgrade and serve the purpose of spinning reserve, peak shaving and load leveling. Since then, fuel consumption is reduced in all operational modes with over 2 million liters of diesel per year, saving up to 30% fuel.
