José Juan Domine, Joaquín Tintoré and Enrique García incorporated Trasmediterránea on 26 November 1916 by combining their shipping companies; operations began on 1 January 1917. Management moved from Barcelona to Madrid following an April 1923 decision, while the registered office remained in Barcelona. In 1931 the Republic required names honouring the monarchy and its politicians to be replaced by city names; Ciudad became the usual fleet prefix. The company moved to Cadiz in 1936 as the Civil War divided its fleet between the two sides. In 1978 most state-held capital passed to Trasmediterranea State Society. SEPI subsequently held 95.24%. Interests included freight forwarder Naviera Mallorquina, charterer Agenica Schembri, Royal Hispania from 1994, and one-third of Spanish Cruise Line, which began activities in April 2001. Navicon is recorded as a possible agent.
Privatisation in 2002 transferred SEPI’s holding to a consortium led by Acciona Logística with 60%, alongside Caja de Ahorros del Mediterráneo, Compañía de Remolcadores Ibaizábal, Agrupación Hotelera Dóliga, Suministros Ibiza and Naviera Armas. The name became Acciona Trasmediterrànea, though the 2011–12 register still used Compañia Trasmediterrànea with Acciona in parentheses.
Spain, Barcelona; management later in Madrid.
