Denmark will send a naval vessel to West Africa’s Gulf of Guinea to aid the fight against rampant piracy.

The decision follows a call by A.P. Moller-Maersk A/S and shipping industry groups for a more assertive international response to kidnappings that occur in the region. The waters in the area are the most dangerous for seafarers worldwide, accounting for almost all maritime abductions in recent years.

The Danish government will deploy a frigate equipped with a helicopter to patrol international waters in the gulf from November for an initial period of five months, according to a statement published Tuesday. The vessel will combat piracy by providing escorts to civilian shipping and carrying out rescue operations following attacks, it said.

Last year, 95% of the 135 seafarers seized worldwide were kidnapped in the gulf, a vast expanse of the Atlantic Ocean stretching from Senegal to Angola, in 22 separate incidents, according to the International Maritime Bureau. Hostages are usually taken to Nigeria, where ransoms are negotiated.

Copenhagen-based Maersk, the world’s biggest shipping company, is responsible for more than a third of maritime trade in the gulf, while as many as 40 Danish-operated vessels sail through the area daily. Maersk said in January that “effective military capacity” needs to be dispatched to the region.

“If we are to get serious about managing security in the Gulf of Guinea, an international military presence is necessary,” Danish Defense Minister Trine Bramsen said in Tuesday’s statement. “We are working for more countries to assume a responsibility.”
