Liquid Cargo Handling Simulator (LCHS)

Today, the problem of accident rate on ships carrying liquid cargoes, remains an important issue. Cargo handling/ballasting and auxiliary operations simulators are the only means of training qualified liquid cargo tanker and gas carrier personnel in the tasks required to perform their functions safely and efficiently.

These simulators can be used for studying the tanker’s layout, its gear and systems, for training in systems and machinery control and in the correct performance of cargo handling operations in both standard operating conditions and in emergencies.


  • familiarising with the tanker layout, its machinery and systems;
  • training in the control of systems and plant;
  • study of the design and operation of the parameter monitoring and alarm systems;
  • training in the correct performance of operations and standard and emergency situations.


The advantages of Transas simulators consist of a number of unique solutions and approaches:

Load Control System

The Transas simulators use LCS, which is in operation on board 900 ships worldwide.

Different cargo types

In the simulators, different cargo types can be selected from the available database. These databases have been expanded to allow carrying out operations on practically all the types of cargo.

Accurate mathematical model

The mathematical model is superior in its implementation to the models used in simulators by other producers. The mathematical model in use allows processes to be accelerated without detriment to the physical realism, whereas the training time is reduced.

Graphics user interface

The interface is optimised for familiarisation with the entire system operating principles as well as for acquiring practical skills for handling the equipment. The main tanker units are implemented as 3D objects, cross sections of individual assemblies are shown. Computer animation is used for displaying the current processes.


In compliance with part I/12, the simulator allows:

  • training in Maritime Academies and Coastal centres;
  • competency checks at the Maritime Administrations and crewing companies;
  • onboard training and demonstration of competency.

In compliance with A-I/12, the Transas simulator features:

  • LCHS class in Guangzhou Training Centre, Chinaoperational capabilities and limitations of shipborne equipment,
  • phisical realism appropriate to training objectives as per (p.1, pp.2);
  • behaviour of shipboard systems imitated by the mathematical model and the user interface as per (p.1, pp.3);
  • instructor capabilities enabling monitoring of the operational environment (p.1, pp.4), tracking of exercise conduct procedure and debriefing of trainees (p.1, pp.6).

The simulator allows basic watch and chief officer training within the framework of A-II/1, A-II/2 in the part of:

  • cargo planning, safe loading and unloading cargoes;
  • prevention of sea pollution;
  • maintaining of the ship stability and seaworthiness;
  • study of the ship design and systems.

The simulator has a number of capabilities which allow basic watch and chief engineer training within the framework of A-III/1, A-III/2 in the part of:

  • control of pump ang piping systems;
  • operation of ballast and cargo handling system;
  • maintaining of the ship stability and seaworthiness;
  • study of hydromechanics.

The simulator allows special training of the ship masters, officers and the crew within the framework of A-V/1 in the part of:

  • characteristics of transferred media (p.2, p.11, p.18, p.26);
  • tanker design and equipment (p.10, p.17, p.28, p.30);
  • ship operations (p.12, p.19, p.31);
  • emergency procedures (p.14, p.21, p.33).

For full compliance with the Convention requirements, the LCHS has been supplemented with Load Control System module which makes the simulator compliant with requirements of B-I/12 p.40 in the part of:

  • LCHS class in Meriturva Training Centre, Finlandeffective operation enviroment, including cargo control station for handling and stowage of cargoes (pp.1);
  • modelling of the ship stability and stresses on its hull in the course of cargo handling operations (pp.2);
  • imitation of fluid transfer operations and related calculations(pp.3).

In addition, Transas has incorporated in the simulator 3D animation capabilities for the operating machinery as per recommendations B-V/1 (p.2, p.4, p.6), and following recommendation (p.15) Transas has developed models of concrete tankers currently in operation.
