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).

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…

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…

Equipped with a GE electrical induction-based propulsion solution, the Woodside Rogers can be powered by tri-fuel engines that run on natural gas, marine diesel gas or heavy fuel oil.

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…

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 propulsor 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.

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.

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.
