Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	8. Goodwill In March 2020, the overall offshore market conditions declined primarily due to the outbreak of the COVID-19 pandemic and the developments in the global oil markets. This decline was evidenced by lower commodity prices, decline in expected offshore rig counts, decrease in our customers’ capital budgets and potential contract delays. As a result, an interim goodwill impairment analysis was performed in connection with the preparation and review of financial statements during the first quarter of 2020. Based on this analysis, we fully impaired our goodwill balance of $7.7 million, all of which was in the Eastern Hemisphere reporting unit. These charges are reflected as "Impairments" in our Consolidated Statements of Income (Loss).
