Swedish Electric Ferry Gets Superfast Charging
Swedish power company Vattenfall and compatriot electric ferry propulsion systems and marine consultancy platform Echandia Marine cooperate on electric ferry with superfast charging.Vattenfall and Echandia Marine have developed a new solution for electric ferries that is designed to minimise emissions and noise and at the same time lower operational and maintenance costs and provide superfast charging.The systems are installed on E/S Movitz that operates in central Stockholm and…
ABS to Class First 'Tri-fueled' Vessel for Harvey Gulf
ABS has been selected to class two Offshore Supply Vessels (OSV) being retrofitted with a battery/converter system by Harvey Gulf International Marine.The Harvey Energy will become the first ABS-classed dual fuel and battery vessel and the first U.S. flagged OSV equipped with a battery/converter system. The Harvey Supporter will become the second vessel in the Harvey Gulf fleet to have a battery power system.The battery installation, which is expected to achieve the ABS class notation ESS-LiBATTERY…
Rolls-Royce Receives AIP For Hybrid Tug Propulsion System
Rolls-Royce received Approval in Principle (AIP) from classification organization ABS for its novel hybrid propulsion system for tractor tugs.The AIP was granted following an evaluation of the world’s first hybrid tug, a unique vessel designed by Jensen Maritime and which Nichols Brothers Boat Builders will deliver to Baydelta Maritime LLC in February 2019. The vessel will be the first tug boat installed with the Rolls-Royce hybrid propulsion system.ABS considers the Rolls-Royce hybrid system is…
ABS Grants AIP for Wärtsilä HY Hybrid Power Module
Wärtsilä’s hybrid power module, the Wärtsilä HY, has been granted Approval in Principle (AIP) by ABS. This AIP follows another issued by ABS in 2017 for Wärtsilä’s hybrid propulsion tug designs.Wärtsilä said it leveraged its strengths in both engine design and electrical and automation (E&A) systems do develop the fully integrated hybrid power module combining engines, an energy storage system and power electronics optimized to work together through a newly developed energy management system (EMS).
Tech File: Propelling Hybrid Electric Solutions
Growing interest in hybrid-electric power systems is expanding the search for new propulsion and energy-storage systems in the workboat sector, where compliance with emerging environmental regulations and a relentless pursuit of operational efficiency are driving change. To meet demands for cleaner more efficient power, owners are examining the potential for less conventional methods of energy generation and storage – such as fuel cells, lithium-ion batteries, super-capacitors, flywheels, wind and solar – to propel their vessels.
ABS: New Guidance on Energy Storage
ABS has published The ABS Guide for Use of Supercapacitors in the Marine and Offshore Industries (Supercapacitor Guide) to support safe application of hybrid power in the marine and offshore industries. The maritime industry is increasingly interested in using supercapacitors as an energy storage solution when quick energy delivery is required during a peak loading condition. Particularly, offshore supply vessel (OSV) owners are considering supercapacitors to supplement energy supply during high-load operations, such as using power thrusters for dynamic positioning while station keeping.
ABS Advises on Hybrid Electric Power Systems
ABS has published the ABS Advisory on Hybrid Electric Power Systems to help marine and offshore owners and operators make decisions about energy generation and storage. “ABS continues to lead industry safety with the first comprehensive Advisory to address the latest hybrid electric power technologies,” said ABS Chairman, President and CEO Christopher J. Wiernicki. With the increased industry focus on environmental compliance and operational performance, many owners and operators…
Maran Takes Delivery of Electric LNG Carrier
The first electrical LNG carrier to be ordered by Maran Gas incorporating induction-based electric propulsion motor technology from GE’s Power Conversion business is expected to enter commercial service in July. The Woodside Rogers, built by one of the major Korean shipbuilders, Daewoo Shipbuilding & Marine Engineering (DSME), at its shipyard near Busan, successfully completed sea trials in late April and was handed over to Maran Gas on July 1. It is the first of seven LNG carriers…
New Control Systems Installed on USS Mount Whitney
Naval Sea Systems Command completed the installation of new control systems aboard USS Mount Whitney (LCC 20), April 8, which will reduce fuel usage and crew workload. Engineers from the Naval Surface Warfare Center Carderock Division - Ship Systems Engineering Station SSES installed the new control systems on a number of shipboard engineering components and are specifically designed to improve automation on the optimally manned ships. "Military Sealift Command-operated ships like the Mount Whitney traditionally have lower manning levels…
MetalCraft Unveils First Electric Powered Patrol Boat
Patrol Boat-1 is really the first, the first ever electric powered patrol boat. MetalCraft Marine designed and built the boat for the City of Annapolis’ Harbormaster. The boat utilizes a Steyr hybrid diesel/electric engine that permits either electric power or for higher speeds, diesel power. The propulsion is a Hamilton 274 waterjet. The jet can propel the boat in electric patrol mode at 4.5 knots, as it approaches and checks boats in the harbor ensuring anchoring permits are valid.
