A Nigeria LNG vessel has evaded a pirate attack in the Gulf of Guinea.

A suspicious approach was made to the 176,809-cbm LNG Lagos II (built 2016) while it was underway 173 nautical miles (320km) off Nigeria on Friday.

A wooden boat with between eight and 10 people on board, carrying "ladders and hooks", closed to a distance of 0.5nm, according to security consultancy Ambrey.

The master carried out evasive manoeuvres while crew gathered in the citadel.

Ambrey tracked the gas carrier turning to starboard and increasing speed from 12.7 knots to 16.3 knots.

Voyage restarted

The vessel has since resumed its voyage from Sagunto in Spain to Bonny in Nigeria.

The incident highlights the heightened risk in the region since the monsoon rains stopped in October — and the huge distance offshore that the gangs can strike.

Attacks have been almost daily, with 13 crew kidnapped from two general cargoships this week alone.

A Greek tanker has also been boarded three times this month.

Nigeria LNG did not reply to a request for more information.
