China Auto Corp (CAC) associate Neftech Pte Ltd reports signing an agreement with American President Lines (APL) to install its proprietary cavitation fuel treatment technology on the main engine of one of APL's largest vessels, a 10,100 TEU container ship. The agreement also gives APL the option to buy the system for up to 10 such ships, subject to a minimum of four. The latest agreement follows a multi-million dollar deal with APL unveiled earlier this year in which APL purchased Neftech main engine systems for four of its 2,500 TEU ships. Neftech say that two systems have already been installed and the third one will be delivered this month with the fourth unit scheduled to be delivered in May 2012.
