Kongsberg has signed an agreement with MEXMAR, for installing a new integrated ‘Full Picture’ technology on the Platform Supply Vessel (PSV), SEACOR Maya, focused on decreasing CO2, NOx and SOx emissions and reducing operating costs through reduced fuel consumption.

Mantenimiento Express Marítimo SAPI de CV (MEXMAR) is SEACOR Marine’s joint venture in Mexico, which operates 15 offshore supply vessels. Kongsberg will supply full integration of the energy storage system with a custom designed Energy Control System (ECS), and the existing Dynamic Positioning (K-Pos DP-22) and Integrated Automation System (K-Chief 700 IAS), both of which will be upgraded as part of the contract.

The upgraded K-Pos DP-22 system functions include Power Load Monitoring and Blackout Prevention. The system will display all battery data including capacity and status, supporting ability to maintain position on DP even after a worst-case single thruster or power failure.

Core components of the system include Dynamic Load Prediction, Dynamic Inertia Control and Dynamic Hybrid Control combined with an automatic start/stop strategy. This optimisation enables significant fuel efficiency while also extending battery life, lowering lifetime costs and maximising the investment in hybrid power.

The delivery is planned in January 2018 and the contract includes an option for a second vessel.

“On completion of the upgrade, SEACOR Maya will feature one of the most advanced powertrain solutions of any vessel at sea,” said Tim Clerc, Manager of Engineering, SEACOR Marine. “The hybrid power solution has the potential to significantly reduce operational costs while at the same time provide access to new functionality for improved safety and effectiveness of DP operations.”
