MAN Diesel & Turbo (MDT) is providing the compressor technology for Shell Canada’s Quest Carbon Capture and Storage (CCS) Project, located in Alberta, Canada. Quest will be the world’s first commercialscale CCS project in an oil sand operation. Quest will capture more than one million m.t. per year of CO2 from its Scotford Upgrader and store it deep underground at a nearby injection site. Quest will begin injecting CO2 in 2015. Shell ordered a RG-type integrally-geared centrifugal compressor from MDT for delivery in 2013.
MDT Berlin will construct and hand over this type RG90-8 frame size for the first time. Four pinions are engaged with a different gear ratio, thus leading to diverse rotating speeds. Each pinion mounts two impellers in a back-to-back arrangement. They are compressing the CO2 in eight stages to a discharge pressure of 130 bar. This integrally geared centrifugal compressor handles 80,000 cubic meters of CO2 per hour. The discharge pressure of 130 bar is sufficient to send the compressed CO2 about 60 kilometres via an underground pipeline to a wellhead, as well as injecting the dense-phase CO2 2.3 kilometers below the surface into a saline rock formation for permanent storage.
With the U.S. shipping industry facing a period of upheaval and with tighter environmental restrictions coming over the next decade, the popularity of future marine fuels will rest upon commercial considerations, according to a white paper from London-based, FC Business Intelligence (FCBI). Many shipping firms have been forced to find innovative ways to preserve or recover margins eroded by lower shipping rates and higher overall costs, said FCBI. Ship owners, fuel refiners, bunkering providers and others are readying themselves for LNG as a shipping fuel. The huge supply of gas in North America has made LNG attractive as a means of lowering operating costs and meeting environmental standards.
The catalyst for change in the marine fuel market is environmental regulation, enacted by the International Maritime Organization (IMO), according to FCBI. The designation of Emissions Control Areas (ECAs) represents the first step. There are two ECAs in U.S. waters which place restrictions on sulfur oxide (SOx), nitrogen oxide (NOx) and particulate matter (PM) emissions. Marine fuels must have a sulfur content of no more than 1% mass, falling to 0.10% on 1 January 2015. IMO rules also subject vessels to emissions standards for NOx, which are applicable to diesel engines, and vary depending on the engine size and maximum operating speed. LNG-fuelled vessels would make it easier for ships to meet environmental requirements and eliminate PM.
The adoption of these emissions regulations around U.S. waters has increased prices for low sulfur fuels, ultimately pushing up the cost of shipping and causing ship owners to consider alternative options. To add to their concerns, the IMO will carry out a study to determine whether to introduce a global 0.5 % sulfur emissions cap by 2020.
The future appears to be a choice between burning traditional heavy fuel oil fitted with emissions abatement technologies, bringing lower sulfur marine fuels, i.e., marine diesel oil or marine gas oil, or shifting to LNG. There appears to be some consensus that LNG fuel might be more costeffective than using alternative low-sulfur distillate fuels such as marine diesel. Some ship owners and shipbuilders are also considering a dual-fuel approach such as marine diesel and LNG, in order to hedge against the possibility of shortages.
The route to LNG becoming widely used in shipping is peppered with obstacles. The main issues concern the cost of initial investment, the availability of bunkering infrastructure and the cost efficiencies of LNG compared to other compliance solutions. A primary issue is the cost of building an LNGfuelled vessel, or converting an existing vessel for LNG. Adopting LNG requires a purpose- built engine or modifications to an existing one, as well as a significant investment in an LNG tank system.
Lost capacity is also a concern when retrofitting ships. Overall, the estimated cost for an LNG-fuelled ship would be about 20- 25% higher compared to an equivalent vessel. However, a study by Germanischer Lloyd & Man found that payback times for an LNG system compare favorably to scrubber systems. But as the payback time for larger vessels would be longer than 60 months, the LNG system would break even only with the more stringent 2020 IMO sulfur emissions regulations taking effect.

Six two-stage screw compressor units for six offshore oil production installations, known as floating production, storage and offloading units (FPSO), have been ordered from MAN Diesel & Turbo for Brazilian energy company, Petrobras. Each package compresses oil-associated gas in two stages, using a combination of Skuel and CP oilfree screw compressor types, each of which represents one compression stage.
Using horizontally split casings, Skuel screw compressors are able to draw high volumetric flows at comparatively low discharge pressures. By contrast, CP-type compressors with vertically split casings can generate about three times higher discharge pressures, but process lower volumetric flows.
A combination of the two types combines their respective advantages. The Skuel stage pre-compresses the process gas but with increasing density its volumetric flow is reduced. The CP stage is then able to increase the pressure. MAN Diesel & Turbo Brazil is acting contractor, and contractual partner IESA Oleo e Gas S/A has an option on two further units.
