KONGSBERG is pleased to announce that Shell has just signed a five-year contract for the installation of its JAWS (Just Add Water System) software on board 45 LNG carriers chartered by Shell. These are LNG carriers that already use the Kongsberg Maritime K-IMS Information Management System suite of applications.

The signing of the contract follows a successful one-year trial, co-led by KONGSBERG, Shell and LNG shipping service provider Gaslog, on board the LNG carrier Methane Julia Louise. The ship’s shaft power consumption was recorded for nine months prior to the installation of JAWS, as well as throughout the one-year trial with the JAWS software installed, and the trial demonstrated that JAWS could provide significant fuel savings for the vessel.

JAWS is a user-friendly hydrodynamic optimization program with no additional instrumentation required. It calculates the most advantageous operating conditions in real time based on algorithms developed from historical high frequency vessel data. The system continuously issues recommendations for optimum trim and draft, helping crews reduce fuel consumption and GHG (greenhouse gas) emissions. JAWS provides live data that allows ship and fleet managers to monitor and report emissions savings.

K-IMS, on the other hand, is a web-based solution that gives ship’s crews and shore teams continuous access to crucial voyage and vessel data. Providing JAWS as an app in the K-IMS suite makes it instantly available to all K-IMS users.

During the one-year test phase, onboard and shore monitoring confirmed that the JAWS software generated substantial average energy savings of 5% when its recommendations were followed. This benchmark data was compared to performance data collected from sister ship Methane Becki Anne, which followed a similar trading pattern.

One of the immediate results of the tests was the commitment of NSML (Nigeria Ship Management Limited) to invest in JAWS software for 11 of its LNG carriers.

“JAWS has come at a pivotal time for shipping operations,” says Karrie Trauth, Senior Vice President of Shell Shipping and Maritime, “when digitalization is recognized as a key enabler for an industry determined to reduce costs, reduce emissions and improve efficiency. It was encouraging to see JAWS directly referenced in the International Energy Agency’s World Energy Outlook 2021 flagship report as a key technology to meet emissions reduction targets in the shipping sector.

The availability of JAWS via the K-IMS solution will prove essential in view of the imminent review by the IMO of its GHG reduction strategy. In 2023, new constraints will apply to performance measures, notably the SEEMP (Ship Energy Efficiency Management Plan), in which shipowners are required to monitor and continuously improve the energy efficiency of their ships in all circumstances. operations, and the CII (Carbon Intensity Indicator), in which cargo vessels are required to keep their carbon emissions below a mandatory level, measured in grams of CO2 per DWT (deadweight rate) per nautical mile.

JAWS is not only applicable to LNG transport: Shell is currently working with KONGSBERG to include JAWS in the Kognifai marketplace, which will allow the system to become available to ocean-going vessels of all types using Vessel Insight infrastructure.
