The MACS3.NET Loading Computer System is a computer controlled loading system for commercial vessels, developed by Software Solutions Department of INTERSCHALT maritime systems AG. Prior to September 1, 2007 it was offered 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.
The software architecture and user interface of the MACS3 .NET 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:
- Rules & Guidelines of Germanischer Lloyd, chapter "Loading Computer Systems"
- ABS Guidance Notes for the Application of Ergonomics to Marine Systems
- BV Rules for the Classification of Steel Ships, Pt C, Ch 3, Sec 3 "COMPUTER BASED SYSTEMS"
- IACS Recommendation on Loading Instruments (No 48)
The software of MACS3.NET 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:
BELCO Container Management Module
DAGO Dangerous Goods Modules
StowMAN Stowage Planning
SEALASH Lashing Module
MIXCARGO General Cargo Module
RoRo Module
Crane Operation Module
Bulk Carrier Modules
Tanker Modules
BallastMAN Ballast Water Exchange Module
Voyage History
DastyMAN Damage Stability
Online Program (Tanks Online)
The system runs under both 32- and 64-bit operating systems Windows 2000, Windows XP and Windows Vista.
MACS3 Basic Loading Program is designed for all vessel types (container, tanker, bulk carrier, general cargo, RoRo, passenger) in accordance with the unified IACS Requirement L5 "Onboard Computers for Stability Calculations". It is approved by all leading classification societies: GL, LR, ABS, DNV, BV, NKK, KR.
MACS3 Basic Loading Program performs:
Ship stability and strength calculations, covering all pertinent international regulations like e.g. IMO A.749
Numerical and graphical results for Metacentric height GM, trim, heel, draft, shear forces, bending moments and torsion
Metacentric height GM check against various approved GM requirement curves
GZ curve for dynamic stability
Automatic wind pressure calculation
Automatic ballast tank optimization
Tank plan with visual editing
Optional online measurement of tank levels and draft (sold separately)
User interface with tabbed main window for multiple views, all fully customizable
Screen and print reports in PDF, HTML and XML formats
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 enhances the MACS3 Basic Loading Program with easy-to-use container management features. 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.

BallastMAN manages a ship’s ballast water exchange on the high seas in accordance with IMO Resolution A.868 (20).
Sequences of tank emptying and filling can be completely planned and executed, thus making sure that the exchange is carried out both safely and efficiently. During Planning Stage BallastMAN determines the fastest and safest sequence, continually calculating stability and longitudinal strength. During Execution Stage BallastMAN monitors the tank levels online, issues instructions when to operate pumps and valves and warns if a crucial deviation from the plan is detected.
BallastMAN creates the Ballast Water Reporting Form required by U.S. Coast Guard / NBIC, AQIS and New Zealand

Each tank may be switched online or offline individually
