Deep Water Ocean Current Measurements at multiple locations Makassar Strait and Sulawesi Sea, Indonesia
April 2001 to Dec 2004
To augment regional coverage, Unocal requested two (2) additional current meter systems be purchased and deployed at selected locations (confidential) in the Sulawesi Sea and Makassar Strait. Ocean Data designed and installed additional current meter systems over the course of the next several years. Each location was instrumented consecutively, that is, moved from location to location with little intermediate downtime. Field operations were combined with other Unocal-sponsored current measurements in the region. The following table represents the location, water depth, duration of the deployment, and number of service operations. Data return rates for these programs exceeded 99.9%. At this time, Ocean Data personnel were servicing multiple mooring systems during each trip to the region, with trips occurring about every 3-4 months, or more frequently upon special request. The field team consisted of two (2) Ocean Data personnel. In all cases, Ocean Data personnel were responsible for all field operations, logistics, and data management. In what became a routine matter, Ocean Data would initiate email contact with Unocal vessel logistics coordinators, those individuals responsible for rig moves, anchor handling, and supply runs. Based on rig and vessel activities, Ocean Data would utilize available chartered boats to perform the mooring servicing, minimizing delays and cost. Ocean Data designed the servicing operations to be compatible with nearly any available vessel; and demonstrated the proficiency of our methods with a zero-incident safety record (since program inception in 1999).

These mooring systems continue to collect current information presently at additional locations in the Makassar Strait. Ocean Data services these systems and reports results on a periodic basis.
