The U.S. Coast Guard dispatched a helicopter and fixed-wing airplane from Air Station Cape Cod Monday evening after a fishing vessel and tanker were involved in a collision at sea.

Nobody was injured and both vessels remain operational. The circumstances behind the collision are under investigation, a Coast Guard spokesman told WBSM.

The 70-foot F/V Edna May collided with the 605-foot tanker Iver Prosperity about 25 nautical miles south of Martha's Vineyard at around 8:10 p.m. on January 22. The Edna May suffered damage to its bow, and it was escorted by a Coast Guard boat back to its home port of Tiverton, Rhode Island with its four crew members aboard. The Iver Prosperity was checked out for seaworthiness by the Coast Guard, and some holes to the hull were detected. However, the tanker remained its integrity and no pollution was released, the Coast Guard said Wednesday. The tanker remained operational.

The Iver Prosperity, built in 2007, is an oil and chemical tanker flagged in the Marshall Islands, according to publicly available vessel tracker data. At the time of the accident, it had reportedly been traveling from Saint John in Canada to the Port of Providence.

Correction: An earlier version said the Coast Guard Helicopter was dispatched from Station Menemsha. Also, the Coast Guard released updated information about damage to both vessels on Wednesday.
