Marine engineering firm Baker Marine Solutions, based in Covington, Louisiana, has unveiled a new service operation vessel (SOV) design for the US offshore wind industry.
The new BMS 1776 is designed to be built in the United States to ABS class standards and is fully certified to operate in US waters, using US offshore workers, BMS said.
“With the rapid expansion of the U.S. offshore wind industry, U.S. companies must be prepared to build SOVs designed specifically for U.S. shipyards to support the installation and maintenance of domestic wind farms,” said said BMS President Jim Baker. “The BMS 1776 brings this capability home.”
The construction design eliminates the need for advanced manufacturing techniques such as hot and cold rolling of steel, thereby reducing overall construction costs and total construction time, according to the designer.
The BMS 1776 was created with the aim of reducing carbon emissions during the design, construction, operation and maintenance of the ship, BMS said. For example, MARIN’s hull optimization studies have increased hull efficiency by 23%, resulting in a top speed of 13.5 knots.
The vessel is fitted with Siemens’ state-of-the-art BlueDrive PlusC system which will increase safety, reduce operating costs, improve life cycle economics and reduce the overall carbon footprint. Variable speed generators will allow engines to operate at optimum speed setpoints based on the most efficient fuel consumption and torque capacity.
Additionally, an available hybrid battery system can store excess energy and provide peak clipping if needed. The battery system further increases redundancy and improves the dynamic operation of the motors, while reducing the total number of operating hours. Electric regenerative actuation allows the gangway go to work system of the vessel reducing power consumption by more than 80% compared to hydraulic power pack models.
A “digital twin” of the vessel is kept from existing production models, allowing the life cycle of every part on board to be tracked. This results in easy maintenance planning while minimizing downtime. Direct emission monitoring allows operators to track on-board and remote emissions in real time.
