MACS3

The MACS3 Loading Computer System is a computer controlled loading system for commercial vessels, developed by Navis. Prior to October, 2017 it was offered by Interschalt maritime systems GmbH, before by Seacos Computersysteme & Software GmbH.
MACS3 consists of computer hardware and a range of software, which aim to minimize the operational load while loading a vessel, and to prevent any hard limitations from being breached.
Design principles.
The software architecture and user interface of the MACS3 Loading Computer System are designed according to the standard ISO 16155:2006 Ships and marine technology - Computer applications - Shipboard loading instruments, and to the following Rules and Recommendations:
Software structure.
The software of MACS3 Loading Computer System includes the MACS3 Basic Loading Program, performing functions of Categories A and B according to the ISO 16155:2006 and (optionally) a range of additional modules and programs, performing functions of Category C:
The system runs under Windows 10 Professional 64Bit.
Programs and Features.
MACS3 Basic Loading Program.
MACS3 Basic Loading Program is designed for all vessel types (containership, tanker, Bulk carrier, general cargo, RoRo, Passenger ship) in accordance with the unified IACS Requirement L5 "Onboard Computers for Stability Calculations". It is approved by all leading classification societies: 
LR,
ABS,
DNVGL,
BV,
ClassNK,
KR,
CCS.
MACS3 Basic Loading Program performs:
MACS3 Basic Loading Program supports client–server software architecture for distributed cargo management and allows the complete loading condition (container, tanks, general cargo and constant items) to be stored in a single compressed mxml-file, making it very easy for you to exchange loading conditions between ship and office.
BELCO Container Management Module.
BELCO enhances the MACS3 Basic Loading Program with easy-to-use container management features, enabling to create the valid Stowage plan for container ships. It works with high level of integration into MACS3.NET, so any changes to the container cargo are immediately reflected in the MACS3 stability and strength calculations. The results of the MACS3 and BELCO can be displayed simultaneously at any time.
The MACS3 screen and print reporting in PDF, HTML and XML formats is also fully available to BELCO.

Market Penetration.
The onboard loading computer MACS3 is being used in a wide range of container vessels, multipurpose vessels, bulk carriers, tanker vessels, roro vessels and passenger vessels. Its ship library includes more than 6,500 ship profiles. For the container vessel segment, MACS3 holds a share of approximately 65%.
The MACS3 loading computer software has been in use for training purposes since 1999. Initially only available to Germany naval schools, it is now also deployed at European and Chinese maritime universities.
