Description of the Related Art After the production of a subsea well is finished, the subsea well is closed and abandoned. The Subsea well closing pro

Hot and cold tapping procedures are covered below. Hot Tapping For hot tapping, a specialized tapping machine is always required. In addition to the tapping sleeve and machine, the assembly consists of a branch valve (gate or ball) and the cutting device (see Figure 3)

of hot tapping and shutdown procedures, use the above subcategories to calculate the cost of each. 1.3.2 HOT TAPPING COST BREAKDOWN In order to do a cost-benefit analysis, the direct cost estimation for hot tapping needs to be completed. This is done at the start of a project and may

After the hot tapping process the customer will connect the prefabricated and preinsulated new line with the preinsulated Shut-Off valves to the TONISCO Hot tapping Valve by welding. TONISCO hot tapping valves are designed to be used only once. After the new line is completed by hot tapping the sluice plate will be removed and the

To run through a successful hot tapping process, drilling and welding abilities are re-quired. Target systems in the industry of hot tapping are for instance cooling systems, district heating, gas and water distribution. (TONISCO. 2014a.) 2.1.1 About TONISCO Hot Tapping TONISCO developed several drilling devices for hot tapping.

A typical hot tap requires a: the hot tapping drill tapping saddle / clamp, ball valve. Hot tapping takes approximately 30-60 minutes, depending on the size of the hole and the pipe material. Note: Hot tapping can be dangerous and should be performed by experienced technicians only. Care should be taken when using the hot

that the company is not quite at the mini-mum working capital level required. As a reasonableness check to our calcu-lations, we can compare to a hypothetical bond program. Many sureties will often grant a bonded program of ten to twenty times working cap-ital. Therefore 265 working capital times 15 would produce a bonded program of 3,975, or close to 4,000 in revenues. Twenty times working .
