A crude oil tanker has been boarded by knife-wielding robbers while anchored at the Jose Terminal in Venezuela.

Three robbers were spotted by a crew member on deck-watch shortly after midnight late last week, the International Maritime Bureau’s (IMB) Piracy Reporting Centre said.

He is said to have notified the officer of the watch just before the robbers threatened him with a knife and stole his radio.

The alarm was subsequently raised and the crew mustered on deck, resulting in the robbers escaping with their accomplices in a waiting boat.

“Tankers berthed at the Jose Terminal or waiting at anchor are at risk of boarding by thieves,” UK-based security consultancy Gray Page said.

“Sources say there are numerous incidents of robbers boarding vessels at night. In some cases the intruders are armed, often with knives.”

The robbers are said to typically target cash and valuables and any stores that can be easily moved.

“Venezuela has been struggling with civil unrest and a deteriorating economy. There are concerns that some gangs are in collusion with elements of the Venezuelan authorities,” said Gray Page.

Ships operating in Venezuela have been advised to maintain strict watches at berth and at anchor and should be alert to the approach of small craft.

“When possible, a ship’s sides and decks should be illuminated, while pilot ladders and accommodation ladders should be stowed," Gray Page said.

“Ships’ crews are advised not to go ashore as growing lawlessness could put them at risk.”
