DOF Subsea at the moment has two vessels piloting Kongsberg Maritime’s new vessel efficiency optimization instrument
Kongsberg Maritime has launched an clever and dynamic determination help system for optimizing a spread of vessel operations. Called Eco Advisor, the vessel efficiency optimization system displays the vessel operation and its atmosphere, together with energy technology, propulsion, environmental forces and management system dynamics. This allows operators to attain reductions in gasoline, emissions and upkeep prices, with out compromising vessel redundancy margins or vessel operational effectivity.
The vessel efficiency optimization answer is an final result of a joint “Intelligent Efficiency” analysis venture between Kongsberg Maritime, vessel operator DOF Subsea AS (DOF), analysis institutes Sintef and NORCE, and Innovation Norway aimed toward creating applied sciences to observe and scale back the GHG (greenhouse fuel) emissions throughout vessel operations.
With stricter laws and a worldwide want for trade to function as sustainably as potential, EcoAdvisor supplies dwell vessel efficiency optimization recommendation on how ship homeowners can scale back their carbon footprint while on the identical time lowering OPEX.
“EcoAdvisor demonstrates clearly how a decision support tool relying on the power of digitization can help vessel operators remain competitive in a growing green market,” says, Odd Hagen, VP offshore gross sales, Kongsberg Maritime. “Several factors contribute to inefficiencies in maritime operations, such as multiple engines running at low utilization, load variations, and large power fluctuations due to mission equipment and thrusters. Vessel owners have found it challenging to achieve sustainable operations due to conservative requirements from charterers and a lack of a holistic overview of their operations.”
“EcoAdvisor creates an intelligent and comprehensive overview of all these factors, delivering advice that enables efficient, cost-effective and sustainable solutions to be made without compromising vessel redundancy margin,” says Hagen. “Further, the history log and reporting functions in EcoAdvisor™ can be used to determine the Energy Efficiency Existing Ship Index (EEXI) the Energy Efficiency Operational Indicator (EEOI) and Carbon Intensity Indicator (CII) to ensure compliance with IMO regulations.”
REAL-TIME DATA
EcoAdvisor works by gathering and analyzing real-time information from varied methods onboard. These embody dynamic positioning (DP), built-in automation methods (IAS), navigation and energy administration methods (PMS). This information is handed by way of a non-linear optimization solver to seek out the optimum arrange of the facility plant for the present environmental situations, contemplating the demand from varied customers together with thrusters, mission gear and lodge masses. The optimum load reference for engines and state of cost reference for batteries is computed based mostly on their effectivity and energy loss.
Based on this evaluation, operational recommendation is supplied to the captain, DP operator and chief engineer on what equipment (engines, batteries and thrusters) could be stopped to run the vessel extra effectively and sustainably. This recommendation is dynamic – if a change within the imply climate situations (wind, wave and present), energy plant system or DP system settings is detected, EcoAdvisor’s suggestions might be revised accordingly. All recommendation is backed up by a system overview indicating why these adjustments are fascinating, how any steps will alter the stability between effectivity and redundancy margin, and what the real-time impact of the measures are.
EcoAdvisor features a Voyage Energy Calculator (VEC) function for transit operation. This helps the operator to find out the whole power consumption for various pace profiles together with added resistance resulting from wind, wave and present for chosen routes based mostly on the climate forecast. This permits operators to resolve the optimum pace with minimal gasoline power consumption for a particular journey, in line with their departure/arrival time necessities.
Utilizing EcoAdvisor’s revolutionary vessel efficiency operation options on the usage of turbines, thrusters, and the setup of the facility plant, whereas sustaining and making certain security throughout DP operations, DOF at the moment has “Intelligent Efficiency” pilot schemes working on two vessels (Skandi Vega & Skandi Africa) and is anticipating optimistic information from these.
“We see there is potential for both savings and reduction of greenhouse gas emissions, and if the result from the pilot vessels is as expected, we anticipate that this will be installed on a larger part of our fleet”, says Arnstein Kløvrud SVP Technology & built-in options at DOF.
