Well over 100 rigs worldwide and a vast number of FPSOs and FSOs rely on Hamworthy KSE equipment for essential functions and operational reliability
On Booth 1463 at OTC 2003 the company will demonstrate technologically advanced systems targeting crude, LPG and LNG markets. In partnership with Navion ASA, Hamworthy KSE has developed a new solution to the environmental problems related to VOC emissions from shuttle tankers. Following a year-long development project, Hamworthy KSE has brought to market a commercially viable VOC recycling system, incorporating proven components and technology.
Development has been focused on the effect of using blanket gas consisting of hydrocarbons produced from liquid VOC to maintain overpressure and keep the tank atmosphere below explosion limits.
VOC recycled to the cargo tank during unloading forms a hydrocarbon blanket which reduces the release of VOC from the crude by as much as 40%.
VOC emitted from the crude oil during loading is condensed in a process plant, and components such as methane and ethane are burned in a boiler to produce steam to be used for operation of the plant.
The solution developed by Hamworthy KSE and Navion reduces the environmental impact of crude transportation and handling by a factor of six (CO2 equivalent) compared with competing systems.
The plant is self-sufficient in terms of its energy requirement, and its complexity and cost have been reduced as a result of the lower emissions.
Minimisation of cargo shrinkage is reflected in added value for involved parties along the product chain.
Hamworthy KSE is a pioneer in reliquifaction and regasification systems for LNG carriers, with experience which is second to none.
The basis for the Hamworthy KSE system is the skid-mounted Moss RS cryogenic heat exchanger, which is specially developed for LNG applications.
By reliquefying boil-off gas onboard the vessel and returning it to the cargo tanks, the system delivers substantial economical and technical benefits.
The system supports the LNG market’s move towards diesel propulsion for LNG vessels, bringing cost benefits in comparison with dual-fired diesel engines.
The company is in discussion with leading players in the LNG market on reliquefaction projects, and is engaged in an ongoing qualification programme with ExxonMobil.
The company is also involved in studies and budget quotations with major customers for skid-mounted LNG regasification systems in the pressure range 40 to 130bar and capacity range 50 to 1000t/h.
There are three alternative HKSE systems steam based, seawater (alternatively with steam backup), and cascade.
They are designed to be located on an FSRU (floating storage regasification units) permanently anchored to receive LNG from carriers, or on SRV (shuttle regasification vessels) overlapping at unloading sites in order to ensure continuous send-out.
Both types of installation are under discussion with El Paso, Bergesen and GolarLNG, while Hamworthy KSE has a co-operation agreement with L Hoegh.
A dedicated version of Hamworthy KSE’s Svanehoj deepwell cargo pump is capable of handling cargoes at around -163C, and represents an extremely economical alternative to submerged deepwell pumps for LNG applications.
In addition, Hamworthy KSE’s Singapore office has received its largest-ever single order for engine room pumps, from Daewoo Shipbuilding and Marine Engineering in Korea.
The pumps are destined for three 138 000t LNG regasification vessels under construction for Exmar Offshore Company.
Hamworthy KSE met the technically demanding requirements of the oil and gas industry to secure the contract to design and supply LPG cooling and reliquefaction plants for a 135 000m3 LPG FPSO, built at the Kure shipyard of Japan’s Ishikawajima-Harima Heavy Industries and destined for the Sanha condensate complex.
The vessel is designed to receive mixed LPG gas from two production platforms, fractionate it onboard to separate butane and propane products, and chill each product stream for storage to await periodic transfer to LPG export tankers.
The scope of equipment supply includes large propane and butane cooling and reliquefaction plants, comprising skid-mounted units with screw compressors, together with 18 Svanehoj deepwell LPG cargo pumps and four booster pumps.
