Research in Ballast Water Exchange for a Jack-Up Drilling Unit

Abstract

A new IMO Ballast Water Management Convention was adopted and came into force in 8th Sep. 2017. The IBWMC (International Ballast Water Convention) covered four major vessel types: Single/Double Hull Tanker, Bulk Carrier and Containership. Research in BWM (Ballast Water Management) of Jack-up Platform is rare. The Jack up was built prior to the date which Convention comes into force and was delivered after date, so BWM of the Jack up is focused on Ballast Water Exchange Plan, which should be approved by Flag State or by CLASS (if authorized by Flag State). In this paper, a sequential method is hosen to exchange ballast water, and calculation is carried out to ensure that the stability is maintained in whole process.
