The largest containership ever to dock in Honolulu slipped into the harbor Monday morning — but not under its own power.

The 1,138-foot Sofie Maersk, a fully loaded containership from Denmark capable of holding more than 7,200 containers, was towed into Honolulu Harbor after losing power to its main engine and drifting since early March.

The massive blue-hulled ship, with dozens of rows of containers stacked 10 or more tall, will undergo engine repairs and take provisions here before it continues on its way to Asia, according to maritime industry news reports.

The ship is the largest container ever to visit Honolulu Harbor, the U.S. Coast Guard reported. Tied up at Pier 2, the ship is so loaded with cargo, its bridge at midship barely sticks out over the stacks of containers.

Petty Officer 3rd Class Amanda Levasseur said a Coast Guard crew boarded the ship Monday morning and will finish its inspection today.

The standard port inspection of an international vessel examines such things as structural integrity, registration and other required paperwork, she said. Levasseur added that nothing looked out of order Monday.

The cargo is expected to remain on board during the repair, according to the World Maritime News, and the estimated arrival in China — originally scheduled for March 9 — is now set for April 8 at the earliest.

The Sofie Maersk was built in 1998 by Copenhagen-based Maersk Line, the world’s largest container shipping company. Attempts to reach the company Monday were unsuccessful.

According to several reports, including the Insurance Marine News, the ship suffered an engine breakdown in the North Pacific on March 4 and was drifting until about March 16. That’s when the Resolve Pioneer, a U.S.-flagged, 80-ton ocean-going tugboat from Alaska, met up with the crippled vessel and began towing it toward Hawaii.

A potential cause of the engine failure was not disclosed, the World Maritime News said.

The Sofie Maersk reportedly has a rotational voyage that takes it across the Pacific from Balboa, Panama; Buenaventura, Colombia; and Lazaro Cardenas, Mexico, to Qingdao, China; Shanghai; and Busan, South Korea.
