The key Venezuelan oil terminal of Jose has been partly closed by a tanker allision.
The weekend accident closed the South dock at state oil company PDVSA's offshore platform, Reuters reported.
It cited three sources as naming the vessel involved as Eletson Corp's 73,000-dwt Meganisi (built 2004), which was bringing in heavy naphtha from the US.
It has been moved to Jose's East dock, but had not finished discharging, the report said.
PDVSA has not commented.
Eletson confirmed to TradeWinds that the tanker was involved in an incident "while berthing alongside an offshore platform at the South Pier of Jose Terminal, Venezuela."
"The vessel was proceeding to the South Pier to berth as instructed, with a pilot on board and three tug boats assisting," it added.
"As she was smoothly moving into position alongside the pier, she touched a fender which collapsed upon contact.
"The berthing was aborted and the vessel was instructed by the terminal to move to a different berth, where she is currently unloading and scheduled to sail on 31 August."
There were no injuries, no oil pollution and no damage to the vessel.
Eletson immediately contacted the UK P&I Club and all relevant authorities.
It is not clear how long repairs to the dock will take.
The East and West docks had no more capacity to discharge naphtha imports and load crude for export, the sources said.
VLCCs are taking up to five days to load there, they added.
Earlier this month, ConocoPhillips and PDVSA reached a payment agreement in a $2bn arbitration case, halting a dispute that had blocked PDVSA exports from its Caribbean terminals.
The case related to the nationalisation of Conoco assets more than 10 years ago.
Conoco had seized PDVSA assets to enforce an international award for compensation against the Venezuelan company.
PDVSA agreed to make an initial payment of around $500m within 90 days of signing the agreement.
The remainder is to be paid quarterly over four and a half years, Conoco said.
