LNG-FUELLED MARINE VESSEL TRAINING SYSTEM

According to IMO’s IGF Code of January 1st, 2017, personnel working on vessels using gases or other lowflashpoint fuels must be properly trained. These training requirements are further addressed through STCWregulations. Kongsberg Digital’s latest K-Sim Engine model, Diesel Electric Dual Fuel Cruise Ferry, enablessafe, realistic and efficient training on LNG-bunkering procedures for engineering students and crew. It isspecially designed to support IMO’s IGF Code and STCW’s new requirements for basic and advanced training

IGF Code and STCW regulations

Because of stricter environmental requirements for sulphur emissionin shipping, LNG is increasingly used as a clean fuel alternative, specifically for vessels operating in Emission Control Areas (ECA), suchas the North Sea, Baltic Sea and designated coastal areas in theUnited States and Caribbean Sea. The 2020 global sulphur limit isset at 0.5%, which will increase the use of LNG as a fuel worldwide.

Based on IMO’s IGF Code the STCW requirement raises the bar forthe education of students and seafarers responsible for safety duties,as well as masters, engineer officers and other personnel with directresponsibility for the care and use of LNG-fuelled systems on a vessel.

In order to satisfy section A-V/3 paragraph 1 of the STCW requirements, basic training is required for all seafarers responsible for designated safety duties related to the care and use of LNG fuel in additionto emergency response on board ships subject to the IGF code.Whilst for section A-V/3 paragraph 2, advanced training is requiredfor masters, engineer officers and personnel with immediate responsibility for the care and use of fuels and fuel systems on the ships.

Sophisticated LNG-bunkering simulator fulfils the trainingrequirement

Kongsberg Digital provides a range of K-Sim Engine simulator models enabling engineers to learn and practice daily procedures whilegaining vital skills crucial for operational safety. To support propertraining regarding sulphur emissions, the latest engine simulationmodel, K-Sim Engine DEDF42 Cruise Ferry, provides both basicand advanced training for LNG bunkering operations. It provides acost-efficient and safe way to build knowledge and test procedures,while fulfilling IMO’s IGF Code and the STCW requirements in addition to being certified for training by DNV GL.

LNG BUNKERING TRAINING SYSTEM

The new DEDF42 CF model is provided as a PC desktop systemfor student training. It is based on a dual fuel diesel electric configuration with the engine room systems on board a cruise ferry. Inaddition to training on operating a medium speed, dual fuel (gas anddiesel oil) engine, the K-Sim Engine DEDF42 model’s main purposeis to facilitate training courses that comply with STCW.

Main training elements:

  • Characteristics of LNG (low flashpoint fuels quality)
  • Safe working practices with LNG equipment
  • LNG bunkering operation procedures
  • Fire prevention
  • Emergency procedures
  • Operational principles of dual fuel generator installations
  • Fuel oil and LNG supply system for diesel generators

In addition, the simulator includes sufficient control relevant for theparticular ship type enabling the realistic simulation of the ship/truck/shore to ship interface and the required checks and operations.

  • Shore side mimic: selection of barge, tank and truck, includingfuel quality, methane number, Wobbe Index and density
  • Connection/disconnection of shore/ship/truck interface (LNG)
  • Flow rate control
  • Emergency shutdown implementation
  • Purging control
  • Capabilities to simulate effects of excess line pressures andresulting action
  • Onboard LNG storage and bunkering system
  • LNG monitoring system for bunker operation
  • LNG emergency shutdown
  • Gas heating

Dependent on background knowledge and experience of thetrainee, the simulator provides training for system familiarization,operations and procedures for:

  • Propulsion plant Integrated Automation System (IAS)
  • Alarm and Safety Warning System (ASWS)
  • Power Management System (PMS)
  • Propulsion Control System (PCS)
  • Dual fuel diesel generator sets and support systems
  • Electric power supply incl. switchboards and distribution centre
  • Ventilation control system in machinery space

INSTRUCTOR CONTROL& ASSESSMENT

Kongsberg Digital Engine Room and Cargo Handling simulators havea state-of-the-art Instructor, Monitoring and Assessment system.In close cooperation with experienced worldwide instructors, the Norwegian Maritime Directorate and DNV GL, Kongsberg Digital has designed and developed a user-friendly and efficient approach that enables instructors to optimize the pedagogical value of exercises for students.

The Instructor can easily configure each Student Station to define what information shall be accessible and visible, including defining which subsystems apply to each station, and indicators that should be viewed. Instructors have access to a unique tool that allows the assessment of students on all levels, from support to management.This allows the Instructor to monitor, and use for assessment, not only alarms, but any of the available variables in the simulation model.

The assessment can be performed during simulations where theInstructor is absent. The instructor has the possibility to print out assessment reports for each individual student reflecting his performance, including pass or fail. The Instructor, Monitoring and Assessment system also has an intuitive and user-friendly feature for Recording and Replay, allowing full debrief after simulator exercises.

We are pleased with the LNG bunkering solution delivered by Kongsberg Digital. The system enables us to offer advanced training for ships subject to the new IGF code, including simulated training scenarios. The simulation training is provided in a safe and realistic environment, where students and professionals can learn to better understand the complexities, risks and hazards of working with LNG

DNV GL COMPLIANCE

In addition to meeting the STCW requirements based on the IMOIGF Code, the K-Sim Engine DEDF42-Cruise Ferry model has achieved DNV GL Statement of Compliance as a Class S simulator.This is based on latest DNV GL Standards for Certification of Maritime Simulators that addresses specific requirements for simulatorsused for training ship`s officers using LNG as fuel.The DNV standard is based on the requirements of the STCW convention which requires the approval of simulators when used for mandatory simulator-based training, or when used to demonstrate competence.
