The growing demand for dynamically positioned (DP) vessels to operate in water depths to beyond 2500 m requires reliable and redundant acoustic position reference systems. This has placed demands on improved repeatability and accuracy which is better met by Long Baseline (LBL) equipment. However, the major limitation of LBL systems is the requirement to deploy and calibrate transponder arrays prior to commencing operations. This has typically been carried out by a dedicated survey vessel, requiring detailed planning and co-ordination to minimize the cost impact on DP drilling vessels. This led to the development of an integrated acoustic positioning systems which can be installed on DP vessels.
