First All-Electric
Ferry in North America

Art Anderson Associates and partner EESImarine have been developing concepts for an all-electric ferry and are now teaming up to generate funding for the implementation of the concept for Skagit County’s Guemes Island-Anacortes passenger and car ferry replacement in Washington.

Art Anderson Associates proposed to the Skagit County Board of Commissioners the all-electric ferry as a viable replacement for their aging ferry, with additional benefits of less lifecycle costs and environmental impacts than a traditional diesel ferry.

The Skagit County Board of Commissioners signed a resolution directing its Public Works Department to conduct an all-electric ferry feasibility study with Art Anderson Associates.

The all-electric ferry being developed will be a practical alternative for operators of shorter-run ferries throughout the world that want to accomplish zero emissions and achieve a reduction in overall costs of operations. It is projected the all-electric ferry will reduce owner costs by up to $170,000 per year and provide an overall breakeven cost after five years of operation compared to an engine-driven vessel.

The vessel’s propulsion and power would be supplied by two battery banks using low-maintenance technology. The battery banks can be easily arranged around required structural support, significantly simplifying vessel arrangements due to the elimination of many engine and fuel support systems.

The power system design requires no exotic hull materials or design and can also be used to retrofit an existing vessel. New all-electric vessel construction costs are estimated at approximately 5 percent more than an engine-driven version.

This design concept has the potential to be a true differentiator in the marine industry as an alternative form of vessel propulsion. With demonstrated performance and future advances in battery technology, this propulsion system can be scalable and ultimately contend with other means of propulsion for cost of construction and operation, and having zero environmental impact.

If successful, this project would be the first all-electric, battery-powered vehicle ferry in North America.


Integrated Wireless Charging/
Mooring to be Developed

An agreement has been signed between Wärtsilä and Cavotec to jointly develop the world’s first combined induction charging and automatic mooring concept. Wärtsilä has developed a wireless charging system based on inductive power transfer. Cavotec provides automated mooring systems for various types of vessels, as well as shore power and reel systems. By combining the strengths and expertise of the two companies, an integrated wireless charging/mooring concept is to be developed for use in Wärtsilä’s ship designs.

Wireless charging eliminates the cable connection between the vessel and shore, thereby securing and facilitating safe connections and disconnections. It also reduces maintenance since wear and tear to physical connection lines is eliminated. Similarly, damage to electrical outlets caused by seawater, snow and ice is also avoided. The new project’s integrated system will be capable of transferring more than 1 MW of electrical energy. This is some 300 times more than that of current chargers used by electric cars.


APOS Survey Installed
On Bibby Offshore Vessel

Kongsberg Maritime Ltd., the U.K. division of Kongsberg Maritime, has completed the first ever APOS Survey installation on Bibby Offshore’s long-term charter vessel, the Olympic Bibby. Launched in December, the new APOS Survey operator station enables surveyors to leverage the power of Kongsberg Maritime’s HiPAP High Precision Acoustic Positioning system to deliver accurate survey results simultaneously while the HIPAP is still used as a DP position reference.

APOS Survey station offers full LBL and SSBL, quicker mobilization times and is designed for both permanent and temporary installation on vessels, negating the mobilization cost and time associated with over-the-side portable transducers.

APOS Survey communicates directly with the HiPAP transceiver, which enables the surveyor to operate independently of the bridge. Acoustic interrogations are interleaved or run simultaneously with the DP system updates, without making changes to the vessel’s APOS software or installation parameters. With APOS Survey, the surveyor can interface local survey-grade sensors, IMU, gyro and GNSS, set up lever arms and load sound velocity profiles independent of the vessel, thus unlocking the full potential of HiPAP for survey operations.


DNV GL Acquires
Gothia Power

Gothia Power, a leading Swedish power system analysis company, has been acquired by DNV GL. This establishes DNV GL’s technical and strategic power system services in the Swedish and Baltic energy markets.

Gothia Power’s 28 power system experts work out of offices in Gothenburg, Malmö, Västerås and Oskarshamn. The company offers advanced analysis and measurements for power production, power transmission and power consumption.

DNV GL’s strategy is to address the energy trilemma of reliability, affordability and sustainability in the energy industry, aligned with the technological and business-related opportunities the company sees in the future.


Seatronics Reaccreditation as
Valeport Calibration Facility

Seatronics is the first to sign up for enhanced accreditation as a supplier of third-party calibrations to the ROV and survey communities globally. The enhanced accreditation is provided by Valeport, a U.K. manufacturer of oceanographic, hydrographic and hydrometric instrumentation.

Seatronics has established calibration facilities in Aberdeen, Singapore and Houston. The original calibration facility was established in Aberdeen in 2003 to manage Seatronics’ extensive range of Valeport assets. Since then, the facility has been extended to handle increased throughput and to support the growing demands of Seatronics’ customers requiring local third-party calibrations. Following the success of the operation in Aberdeen, Seatronics replicated the facility in Singapore in 2005 and in Houston in 2008.
