The webpage at www.oisaonline.com shows an emblem, or seal, consisting of
a chain surrounding a symbol made up of a steering wheel, a ship and an anchor,
said chain in its turn surrounded by the name of the organization in Arabic? and
English. Moreover, there is an inscription (what does it say?) below the central
part of the seal. OISA, the Organization of the Islamic Shipowners' Association
was founded 1981 and is located in Jeddah, Saudi Arabia. Some photos in the file
are very interesting, see p. 2 showing various national, house and/or
association flags plus a large OISA flag. It appears to be green with a white
disk bearing the emblem. The inscriptions are black as far as I can see, the
central part black (upper part inside steering wheel, blue) and the chain
yellow. Jan Mertens, 7 April 2004
Based on description and its logo, I have
created its flag image. Zoltan Horvath, 20 February 2011
