Ship-Based Carbon Capture Techno-Economic Guide

This blog provides techno-economic guidance for the use of SBCC onboard your vessel, including operational impact, logistics and of course the costs for implementation. Key points include the following; SBCC is applicable to virtually all ship types, sizes and fuel type but LNG is preferred. SBCC produces 2 m3 of CO2 per day per MW. SBCC costs €115 per ton CO2, is a CAPEX dominated technology and costs €175k per MW.

MoU for North Star Support Vessels on Offshore Wind

Maersk’s Stillstrom and North Star have signed a Memorandum of Understanding (MoU) to accelerate the adoption of offshore charging and vessel electrification technologies for Offshore Support Vessels (OSVs) in the offshore wind sector. Offshore charging hubs will enable the vessels to recharge their battery systems using wind energy while in the field.

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.

Making the Impossible Possible

This blog sketches a vision on how to convert the largest crane vessel in the world - Sleipnir - owned by Heerema Marine Contractors, to a zero-emission vessel. Several promising carbon reduction measures are combined which are technically viable and based on matured technology including electrification and BES, solar panels, synthetic fuels, CCS and possibly hydrogen combustion.

Ørsted and Maersk to Test Offshore Vessel Charger

Maersk and Ørsted are building a ‘power-buoy’ that can act as both a mooring point and a charging station for vessels, enabling them to turn of their engines when laying idle.
