This text is a case study in why abbreviations should NEVER be used in business communications! Here are my suggestions:
Delivery time -- I presume that this is the title for the next two lines below
ETD Pluritec premises by week 9. -- Estimated time of delivery to the Pluritec office/factory/facilities is in the the 9th week from (now / manufacture / purchase order date) at the latest.
Shipment on the first available vessel. Last shipment date on L/C 10/03/2008 -- It will be shipped as soon as possible. The latest shipment date according to the letter of credit is October 3rd or March 10th, 2008.
