Maneuverability study and economic analysis for tugboat procurement in basin area

Abstract

The growth of the energy industry in Indonesia is increasing rapidly. This study concern about the crude and product oil distribution of one of the biggest oil companies in Indonesia. The distribution of crude and product oil requires large capacity particularly designed bunker transportation, which is an oil tanker. However, the enormous size of the tanker causes the tanker must be assisted by a tugboat to berth at the port of any type of waters. In this study, the simulations were conducted at the Marine Region (MR) III of Tanjung Priok Port, which has a basin-shaped berthing area, to determine the needs of tugboats force based on the size of the tankers. The simulations were carried out in MATLAB software by considering Tankers’ principal dimension, environmental data, Tugboat force (Bollard Pull; BP), and Tugboat’s heading angle. Then, those forces should be combined with each other into several scenarios and reviewed its economics based on the “buy”, “lease”, and “combination” scenario, calculated in the Capital Expenditure and Operational Expenditure factors.
