Mainport Africa Shipping was established in South Africa in 1981.
The company, headed by the then cofounder Sean Minogue, traded as a Liner and non-Liner ships agency with a wide portfolio of clients throughout South Africa. Mainport became a byword for quality and professionalism in the shipping sector in Southern Africa and the predominant agent to the break-bulk and project cargo market
A change of shareholding took place when Irish Mainport Holdings became majority shareholders in 1998. Irish Mainport remained as majority shareholders until 2013, at which time Hull Blyth Group, the Africa ship agency specialists purchased their shares and those of the minority shareholders to become sole shareholder of the company. Fiona Calitz, daughter of the founder Sean Minogue, herself in the business for 20 years, and previously a minority shareholder, was appointed as the Managing Director.
As a wholly owned division of the Hull Blyth Group, Mainport Africa Shipping has the backing of a strong international brand with significant market penetration on the continent, especially in West Africa and substantial financial resource.
