The HiPAP system is a high precision acoustic positioning system that is used for positioning of subsea targets on both shallow and deep water. It uses both Super Short Base Line (SSBL) and Long Base Line (LBL) positioning techniques. The HiPAP system establishes subsea positioning so accurate in SSBL mode that the more complex LBL principle is made redundant within reasonable depths. The time and cost of survey operations are therefore reduced to a minimum.
The HiPAP system is also a reliable underwater reference for Dynamic Positioning (DP) systems. The system always sends raw position data to the DP system, allowing the DP itself to perform the evaluation, weighting and filtering of its references. The HiPAP system is important for safe operation of dynamic positioning systems because it provides extreme positioning accuracy and reliable underwater reference for DP systems.
High Precision Acoustic Positioning System (HiPAP) has a number of advantages and applications that make it useful in various maritime operations and there's a HiPAP Basic Skills video course with more detailed description.
This video material contains experience sharing collected from many years of hydro acoustic usage. It is essential for confident operation of HiPAP system in dynamic positioning and will help you develop your knowledge for the further understanding and use of APOS system. The material involves all necessary explanations and aspects of hydroacoustic system setup and principle of operation for dynamic positioning.
The video material consists of:
- Basic understanding of sound in water, its properties, and its effect from surrounding factors.
- General familiarization with HiPAP and APOS.
- All steps from A to Z in setting up and using the system for dynamic positioning.
- Practical use of transponders and hydroacoustic system in SSBL mode.
- Geographic position in SSBL.
“Basic Operations with HiPAP” is made for the basic level of Marine Officers/DPO/JDPO who would like to boost their knowledge about the sound in water and how to use it for dynamic positioning in SSBL mode (Super Short Base Line). The material is prepared by seafarers for seafarers containing only essential info for beginners to improve confidence in operations with hydroacoustic systems. The material is taken on a live system in operational conditions.
