In December 2022, channel mainetanance dredging project was started at PT. Pertamina Hulu Mahakam offshore seafaring line. The initial plan for this project was to be done on 5 April 2023 (96.6 days) with one clamshell dredger and three set of hopper barges which were towed by two tug boats and one anchor handling tug. But in reality, the offshore channel maintenance dredging completion date, which was performed by PT. KERUK SEJAHTERA using crane barge KS 12, was delayed to 19 May 2023 (43.4 days delayed). Two main problem were identified using Kepner Tregoe Situation Analysis (KT-SA) based on the company data processing and one most main contributing problem (lack of daily sedimen production; the initial plan was 1500 m3/day) then be analysed using Kepner Tregoe Problem Analysis (KT-PA) and the root cause was constructed using cause-map with brainstorming methode included in the process between author and some of PT. KERUK SEJAHTERA dredging crew in crane barge KS 12 (the crew didn’t know how to predict when the equipment will need to be replaced especially for the ones which are not included in the 3rd party inspection scope). Substitute, Combine, Adapt, Modify, Put on another use, Eliminate, Rearrange (SCAMPER) technique then be brought in the brainstorming session with PT. KERUK SEJAHTERA dredging crew on crane barge ABC to bring alternative solutions for the root cause of the problem. Furthermore the SCAMPER result be brought to brainstorming with PT. PHM dredging operation assistant manager, as the problem holder and matter expert, and filterd to three most possible alternative solutions. These three most possible solution then examined using Simple Multiple Attribute Rating Technique (SMART) method with eight stages wer performed. The criteria used in this method are offshore channel dredging project cost, offshore channel dredging project schedule, coordination with other entity, and permit to work (PTW) & derogation. The objective of this research are knowing what factors affecting the dredging project in PT. PHM offshore channel case and the alternative solution to be brought in the next offshore channel maintenance dredging.
