ECDIS Situation Awareness (ECDIS SITAWARE)

As many of you might have experienced the ECDIS training based on IMO/STCW requirements is not enough to give navigators the necessary in-depth understanding. We now offer an e-learning model, called ECDIS-SITAWARE that we claim meets this shortcoming. Our approach is focusing on the necessity to raise the navigators’ awareness of the technical limitations and the pitfalls for unsafe use of ECDIS in various situations.

In this course unsafe use of ECDIS is not understood as poor motivation, rather, limitations and pitfalls are explained in a concrete manner using simple language.

The course is based on a real incident and covers four main themes:

1. Scale Issues

2. Wrecks and Obstructions

3. ENC quality and Alternative Information Sources

4. GPS and AIS positioning

The course starts with an introductory chapter explaining what it means to have situation awareness regarding ECDIS. Ten chapters then covers one awareness aspect each concerning ECDIS use. Each Chapter follows a common pedagogic template in three parts:

1) a short presentation of the awareness aspect,

2) an example taken from a real grounding accident, and

3) a multiple-choice question activating the learner and testing understanding at the same time

The course takes the average learner about 1.5 hours to complete.

Each chapter can also be printed out in standard A4/Letter format as reflection sheets. This makes excellent supporting material for reflective discussion amongst navigation officers. The learners will get an immediate feed-back on their test score in %. In addition, the learner and their employer will receive an overview of the test result.

The system is based and can be used on smartphone, tablet or PC. The course has been tested with positive result in several major shipping and crewing companies.

ASOG simulator training

Learning goals for ASOG training should be based on job specific scenarios, field layout, vessel and platform model and weather conditions to secure that the participants have an in-depth understanding of SOW and ASOG procedures for the subsea operation in question and should include goals such as technical skills as well as teamwork and communication to secure safe handling of

  • thruster failures
  • increasing weather
  • reference systems
  • drift off
  • loss of switchboard
  • drive on
  • drift on using tugs

For each goal the DPOs shall be able to handle any emergency and crisis scenarios including manual takeover when needed.

Assessment of the course participants should be an integrated part of the training session. Technical and non-technical assessment criteria should reflect the nature of the operations an include elements such as

  • Ship handling
  • Operation of DP
  • Use of maneuvering equipment
  • Situation awareness
  • Two-way communication
  • Teamwork

The training at Simsea lasts for two days and consists of two parts.

Part 1: E-learning module to study the SOW and ASOG procedure including a test to document learning outcome. The test will be repeated in the beginning of part 2.

Part 2: Simulator training including a scenario for each learning goal and facilitates a comprehensive review of project procedures in a realistic environment. All personnel involved in the training will be given familiarization in use of simulators and related equipment.

We recommend to use two simulator bridges for each shift of 6 bridge officers. In such a case we will have two DPOs at each bridge. Captain and Chief Officer train in their roles on-board; they will follow the exercises from the instructor room, enter the bridge when they are called for and participate in the assessment of the bridge teams.

A thorough brief will be carried out before each exercise to secure a mutual understanding of the purpose for the exercise and assessment criteria in use. Execution of simulator exercises will be performed as on board per relevant procedures and will be observed by Simsea instructors as well Captain and Chief Officer (one bridge each). A debrief, a two-way feedback session will be performed after each exercise. This session will include learning outcomes and the results of the assessment.I

Lead instructor has many years of DP experience offshore and long experience as simulator and DP instructor. He will in addition to the overall management of the training program be instructor for one of the simulator bridges. He will be assisted of an experienced master mariner and simulator instructors to run the other simulator bridge and to run the tugs in one of the drift-on scenarios. Our lead assessor will be responsible for assessment including coordination of the assessment team. He holds a PhD in organization psychologies and has many years as assessor, simulator instructor and teacher. 3

We will use two K-Sim Offshore bridges including K-Pos DP2 for the training sessions. Both bridges are certified as Class A simulators by DNV-GL. The ship dynamics is simulated on the K-sim offshore vessel simulator. The K-sim offshore vessel simulator integrates advanced physics engines with hydrodynamic modelling of the highest quality to provide realistic ship behavior and interactions. From the simulators instructor station, one can provoke faults in the vessels propulsion plant, power management system, thrusters and sensors. It is also possible to adjust weather conditions such as wind, waves, swell, current, precipitation and visibility.


A fully integrated model of Edda Fauna is set up on DP 200 meters from Kristin to perform riser rectification. The DP system is set up using 3 DGPS, 1 HiPAP and 1 FANBEAM as reference systems. A broadcast voice recording system is available for monitoring communication on bridge.3

E-learning will take place on Simsea’s web-based training platform which is available at lap-top, tablet or mobile phone.
