MACS3 Load Calculator on CCS New Buildings


On three 20,000 TEU new series of the China COSCO Shipping (CCS) group will be installed MACS3 charge calculator. The orders mark a new dimension for the ship's charging computer developed by Interschalt.

As of this year, Navis Carrier Solutions develops and distributes Interschalt's planning software and load calculator. The company from Oakland (USA) marks the global technology standard for the management of cargo movements in terminals. With the integration of Interschalt Software, Navis has extended its portfolio to the carrier market in order to provide more integrated solutions for better visibility and better instruments for the planning and execution of container movements. As of now, software solutions such as StowMan, MACS3 and Bluetracker are under the umbrella of the Navis brand.

The ships, which are now to be equipped with the systems, bear the construction numbers H1413-1415, and are currently being built at the Shanghai Wai Gao Qiao shipyard in China with delivery between April 2017 and February 2018.

The MACS3 ship's charging calculator, according to the manufacturer, covers a wide range of calculations regarding hydrostatic, leak-proof and longitudinal strength. In addition to the hardware, the basic program includes squat calculations, the containment management module BELCO, the dangerous goods module DAGO I, the Lash function Sealash (GL 2013) as well as the on-line interface to the tank measuring system, Hull Stress Monitoring and the trimming optimization module TROP Allows the trim to be optimized with respect to a reduced fuel consumption based on the current charge state.

In addition, a second contract on the equipment with MACS3 of six identical 21,000 TEU sister ships with the construction numbers H1416-17, 1420, 1427-1429 was concluded with the builder Shanghai Wai Gao Qiao, which will be put into service between May and December 2018. The new program with MACS3 on board will complement two additional 20,000 TEU container ships for the CCS group with the construction numbers C20k-1-2, which are currently being built on the Dalian Shipyard and are due to be delivered in March and June 2018.

"These three new builds mark a new dimension for our shiploader, which has never been deployed on ships of this size," says Selke Eichler, Head of Customer Relation Management (MACS3) at Navis Carrier Solution (formerly Interschalt Software) in Flensburg. Through the merger of Chinese Shipping Container Line CSCL and COSCO, the cargo calculator is used on 158 ships of the new fleet.

The MACS3 load calculator has been on the market since 1994 and is connected to XVELA, a cloud-based traffic collaboration platform for line operators and terminal operators, to enable terminal load-plan validation with MACS3 stability calculations. MACS3 is also connected to the StowMan StupMan program, which is used by a number of regular lines, including COSCO. In addition to container ships, MACS3 offers ship-specific loading computers for bulkers, multi-purpose ships and tankers.

With a view to the further development of the software, the next update in April 2017 will include many new improvements regarding the congestion and segregation requirements according to the IMDG Code as well as contingency plans including the latest dangerous goods amendments pursuant to Amendment DAGO 38.
