The two illegal Vietnamese fishing vessels are yet to be destroyed.
A team was sent out on Tuesday and today to continue assessment of the situation.
The vessels were towed out of Fairfax Harbour on Monday by the PNG Defence Force Navy vessel HMPNGS Buna to a sinking site outside Port Moresby.
However, due to bad weather, they were left on a reef off the coast of Fisherman Island.
The destruction was organised by the National Fisheries Authority and planned to be carried out by the PNGDF Navy's explosive ordinance and diving team.
The operation was aborted halfway through due to rough seas which made it difficult for the navy team as the swirls reached about five metres high, making the vessels very unstable.
The assessment team consists of naval personnel, fisheries officers while external clients are Pacific Towing service.
Fisheries officer Mark Bangkoma said they are yet to receive a report from the assessment team which will determine their next course of action.
“The team have gone out to assess the condition of the boats and if they can be towed out about half a mile to the designated area to be destroyed.
“The operation now depends on the assessment by the experts at the Pacific Towing service as the strong winds and rough seas continue to hinder operation,” Bangkoma said.
The vessels were used by 50 Vietnamese fishermen who had been fishing in PNG waters off Budibidi Island in Milne Bay Province. This was on December 22, 2016.
The two illegal vessels were apprehended by the PNG Defence Force naval ship HPNGS Seadler while fishing in the waters of Milne Bay.
A total of 77 drums of beche-de-mer, or sea cucumbers, were found on board the foreign vessels.
The Bomana District Court early this year ordered that the two illegal vessels be destroyed.
