GulfMark Offshore, Inc. (NYSE:GLF) announced Friday it intends to offer $150 million in aggregate principal amount of its 6.375% Senior Notes due 2022 for sale in a private offering to fund vessel construction costs.

The notes will have substantially the same terms as the $300 million aggregate principal amount of 6.375% Senior Notes due 2022 issued by GulfMark in March 2012.

GulfMark says it intends to use the proceeds from the notes offering to repay certain existing credit facilities and for general corporate purposes, including to fund vessel construction costs.

Houston-headquartered GulfMark owns, operates and manages a fleet of modern offshore support vessels that work in support of the upstream oil and gas industry in the North Sea, Gulf of Mexico, and Brazil, among other high growth markets.
