Energy entrepreneur Steve Remp was dealt a financial blow after £2million was wiped-off his shares in SeaEnergy.
Remp, who used to head the Aberdeenshire-based firm, remains the company’s largest shareholder.
The firm is the latest to suffer on the back of a faltering oil price, losing 75% of its stock market value this year.
On Friday the company’s shares closed out at 5.25p – up from last month’s low of 4.37p but a significant drop from June 2011’s high of 69.5p.
Remp is believed to own 4.2million shares in the firm.
In September, the company, which provides technical services and advice to the oil and gas, renewables and nuclear sectors, issued a warning that it would into meet its full-year expectations and it expected to make an operating loss for the year.
