First Container Vessel with MACS3 Loading Computer On-board to Receive Route Specific Container Stowage RSCS+ Class Notation from DNV GL

Vessel owned by shipping company Claus-Peter Offen to profit from improved access to flexible container stowage solutions 

Navis, the leading provider of maritime software solutions for cargo operations and vessel performance, announced today at SMM 2018 that the ship-specific MACS3 Sealash module on board a 8,000 TEU container vessel has been successfully approved by the classification society DNV GL. The vessel owned and managed by Hamburg-based Offen group, is now able to apply the latest update of Route Specific Container Stowage (RSCS+) lashing regulations from DNV GL, July 2018 edition. The update allows the maximum theoretical capacity for this vessel to increase by approximately five percent.

Based on the updated cargo securing manual (CSM), Navis naval architects implemented the RSCS+ model in the MACS3 Sealash software to be approved by DNV GL, which will helps ship owners benefit from route specific container stowage rules. As part of the upgrade in RSCS+, vessels can now access the DNV GL webpage for worldwide routes without additional approval from the class. Using the class-approved lashing computer, the cargo officer can choose between calculations for unrestricted service, long-haul routes and short sea voyages. As a result, more cargo can be safely loaded on the vessels based on its typical trade pattern and weather forecast for short-sea voyages. Additionally, this model allows ship operators to avoid most of the restow operations caused by increased vessel stability after being discharged having returned from ocean passage.

“Our goal was to integrate rules by all major classification societies into MACS3 as quickly as possible to ensure that our customers have access to the safety regulations and economic benefits,” said Guy Rey-Herme, President of XVELA and the Head of the Maritime Solutions at Navis. “Collaboration between the ship owner, lash maker and classification society helped us overcome technical obstacles and led to a swift and successful implementation.”

Navis continues to remain in contact with all major classification societies such as Lloyds Register, Bureau Veritas, American Bureau of Shipping, Chinese Classification Society (CCS), Korean Register (KR) and NK Class to pave the way to a fast integration of their cargo securing rules with Navis software.
