Как в 2-ух случаях перевести HOWEVER,чтобы перевод не повторялся ?

However, through the fault of the manufacture that did not produce the equipment on time and because of the difficulties in providing transport facilities there was a delay in the delivery of the third consignment of loading on November 2016.

However, the validity of the above contract had expired by the time. The validity of the letter of credit for the last third consignment of equipment is over, and that is why we urgently ask you to prolong the time of the L/C till January 2017 or confirm payment of invoices to be мейд for collection.
