Hamworthy is supplying cargo systems for six ships being built in China for the Indonesian state-owned oil and gas company, Pertamina: five products carriers and an LPG carrier.
At the end of April Hamworthy signed a contract for five shipsets of cargo pumproom systems and engineroom pumps. The equipment is for five 30,000 dwt products carriers being built for delivery in 2010-2012 to Pertamina by Zhejiang Chenye Shipbuilding Co Ltd, newly established on the island of Daishan near Shanghai.
“Pertamina has supported us in the past decade with equipment orders for 25 tankers of various sizes built in Indonesia, where the previous two are under construction by PT Dok in Surabaya,” said Terje Bjornemo, Hamworthy’s global sales director for pumproom systems. “We are delighted to add another five Pertamina ships to our reference list.”
Each shipset of pumproom system equipment includes electrically driven VFD (variable frequency drive) operated cargo pumps, and electrically driven ballast pumps, stripping pump and cargo and ballast eductors. The equipment will all be controlled and monitored by the Hamworthy Cargo Control System (HCCS).
“Our pumproom systems for discharging tanker cargoes are controlled by a PLC based control system where all signals are electric rather than pneumatic, a technology that we left behind in the mid 1980s,” Mr Bjørnemo said.
