Cameron International Corp. will close its Drilling Systems – Topsides Controls Group facility in northwest Houston due to the oil and gas industry’s continued challenging market environment.

In a letter to the Texas Workforce Commission dated Dec. 1, 2015, Cameron said that the closing of the facility will result in the permanent layoffs of approximately 55 employees over the next four months. The first round of layoffs will begin Feb. 1, 2016 and then again April 1, 2016, “subject to changing business circumstances and needs,” the letter states.

Cameron will offer severance benefits and transition programs, including outplacement services, to laid off employees. Company policies do not contain provisions for transfer, bumping rights or reassignment, but employees can apply for open positions at other Cameron locations.

Cameron, oilfield services provider, announced in November that the company would be laying off 75 employees at a different Houston facility on Thomas Road beginning as early as Jan. 11, 2016.
