COPENHAGEN (Bloomberg) — A.P. Moeller-Maersk A/S, the world's biggest shipping company, agreed to sell three oil rigs to Bermuda-based Northern Offshore Ltd. for $455 million amid rising prices for oil production equipment.Maersk will hand over the Endeavour, Enhancer and Exerter rigs on June 15, Northern Offshore, a closely held Norwegian oil drilling company, said yesterday in a statement distributed by Hugin.

Rising oil prices over the past three years have spurred companies to step up the hunt for new fields, causing a surge in rental prices for drilling rigs and offshore services.
