IN-LIEU OF DRY-DOCKING (UWILD)

Based on regulation of Direktur Jenderal Perhubungan Laut No. HK.103/1/4/DJPL-14 about Pelaksanaan Dock (Pelimbungan) Kapal Berbendera Indonesia, ship inspection can be performed by the Under-Water Inspection In-Lieu of Dry-Docking (UWILD) method, an inspection of the activity of the bottom of the ship without docking-up to the shipyard. UWILD is an innovation-alternative to intermediate surveys that can be performed on ships under 15 years old. In general, intermediate surveys carried out by dry-docking system, in which ships are required to docking-up to the shipyard and requires a long time. However, by using the UWILD method, the ship don’t need docking-up to the shipyard, but the ship remains at sea and inspected using under-water diving system. Various advantages gained in the implementation UWILD obtained from the time faster, cheaper cost and commission increased ship days.
