The Yantai Raffles Shipyard in China has solved a valve weight problem in the construction of a crane/pipelaying barge by using Amot G three-way temperature control valves, following recent design improvements that proved to make them the lightest and most compact units available. Some 50% smaller in height than typical temperature control valves while still meeting robustness requirements, these industry-standard valves also had the advantage of allowing greater flexibility of piping arrangements. The 157m heavy derrick 3800t barge is a support vessel for offshore platforms in the Bo Hai Bay area of China, used by the China National Offshore Oil Company for equipment lifting and laying oil and gas pipes to the shore. The yard originally selected a different company’s valves for the Wartsila-engined barge, but discovered that those were too heavy during the engineering review. To help reduce weight, the ship owner specified Amot G valves. These provided the required rapid and accurate regulation of fluid temperatures to 100C with a maximum flow rate of 3000mü/h. They also offered the benefit of suiting both mixing and diverting applications with electric, pneumatic or electro-pneumatic controls.
