Free fall lifeboat simulator (full mission, on the dynamic platform)

:: Download details

Purpose

Freefall lifeboat simulator is intended for training of personnel working on ships equipped by freefall lifeboat in accordance with STCW Code:

• Section B-I/14, 1.1 ‘Guidance regarding the responsibilities of companies and recommended responsibilities of masters and crew members’,
  
• Section A-VI/1 ‘Specification of the minimum standard of competence in survival craft and rescue boats other than fast rescue boats’,
• Section A-VI/1, Table A-VI/1-1 ‘Specification of minimum standard of competence in personal survival techniques’.

The simulator can be used to train the coxswains of free fall lifeboats operated on mobile offshore units in accordance with OPITO standard "Offshore Lifeboat Coxswain Training"




Knowledge and skills

The simulator allows to drill the following skills:

• boarding lifeboat,
• freefall launching,
• clear the ship’s side,
• handling lifeboat in rough weather.

Structure

The simulator includes the following equipment and software:

• embarkation station,
• free fall lifeboat,
• 6 DoF dynamic platform,
• computer and video equipment,
• software that ensures the operation of the simulator.

Operational scheme

All students can feel some stress during launching, emergence and being in the lifeboat, but in safe manner.




Lifeboat

The used lifeboat is a part of a real freefall lifeboat with the bow cut off. The bow section is closed by an end bulkhead made of the lifeboat hull material. Maximum overall dimensions L x W x H, м: 3,25 х 2,68 х 1,86. 

The lifeboat is equipped in accordance with LSA Code.

At the request of the customer, the hull of the lifeboat can be marked with the special name of the ship or name of the organization and port of registry as well as logotype.










Dynamic platform

AThe dynamic platform ensures the movement of the lifeboat along the trajectories and at the speed set in the software, including freefall launching and float free, as well as the behavior of the lifeboat on the water surface in rough sea.

Technical characteristics of the dynamic platform:

Dimensions, excluding the boat	2,5 m * 2,5 m * 1 m
Base diameter	2,5 m
Maximum list	24°
Maximum trim	46°
The movement amplitude	Up and down – 0,6 m Aft and ahead – 1 м Right and left – 1 м
Turning	110°
Power consumption	15 kW
Weight	700 kg
Weight of the oil station	180 kg
load capacity	1250 kg
Voltage	380 V + 220 V

*** A new version of the simulator with a different model of the vessel installed on the 6 DoF platform can be developed under the order.

Computer and video equipment

CCTV is installed in the cabin and outside with the output of information to the instructor's workplace, and with the possibility of recording and archiving exercises. Monitors are installed in place of the portholes to display the visualization of the surface situation.

Software

The software consists of:

• Instructor WorkPlace (IWP),
• Student WorkPlace (SWP),
• Dynamic platform control module,
• Module for processing commands from the lifeboat controls.

IWP functions:

• choice of the navigation area;
• adjusting:
• wave height,
• precipitation intensity,
• visibility restrictions,
• time of day,
• drift speed and direction;
• video and audio monitoring of what is happening inside the cabin, the ability to provide a loudspeaker connection for operational messages.
• video recording for debriefing.
• emergency stop of the exercise, return of the simulator to its initial state.

Navigation areas:

• Open sea.
• A part of the sea near coastline, for drilling skills of intentional grounding a lifeboat.

SWP functions:

• Freefall launching
• Starting and operating an engine
• Handling lifeboat in rough weather
• Intentional grounding a lifeboat
• Display of the surface situation

Dynamic platform control module

The module controls the dynamic platform in order to ensure its movement along the trajectories corresponding to the freefall launching and emergence, as well as the behavior of the lifeboat on the water surface in rough weather.

Module for processing commands from the lifeboat controls

The module ensures processing commands from the following controls:

• Engine control panel buttons
• Throttle
• Steering wheel
• Release devices
• Top light button
• Search light button
  

Methodical guidelines for using the simulator

The simulator is supplied complete with guidelines for the use of the simulator, developed in accordance with the Technical description and operating instructions for a freefall fire-proof lifeboat.
