Access and maintenance lifts

Alimak specializes in rack and pinion-driven lifts for industrial locations and has more than 25 years' experience of offshore applications. The modular-built lifts are adaptable in size and capacity and do not need a machine room or lift shaft. The lifts, which are available in explosion-protected designs, provide safe and convenient access in hull columns, derricks, flare towers, and platform modules. Recent offshore references include the Kvitebjørn and Valhall developments in the North Sea, Rig 184 for GlobalSantaFe, and the new Khazar and Mærsk-owned semsiubmersibles for the Caspian. www.alimak.com

These include formed heavy plate details in Weldox and Hardox and armor steels. The company also has fabricated complex shapes for the art world. In 2000-2001, it supplied 304 panels, each unique in shape and size, for the hull of a conference hall in Berlin, designed by architect Frank O. Gehry. www.deform.se

Drinking water treatment

E.C.T. Offshore Service offers comprehensive services for the treatment of drinking water offshore. Its systems have operated on over 250 rigs and platforms, many of which have annual service contracts with E.C.T. Due to the company's close cooperation with the Norwegian government, it can ensure that the installations fulfill their requirement for this service. E.C.T. also runs courses "Drinking water treatment for offshore personnel." www.ectoffshore.se

Galley and laundry appliances

For the last three decades, Electrolux Marine has supplied food service and laundry equipment to the offshore sector. Galleys and laundry onboard platforms, rigs, and supply vessels need to be equipped with the sturdiest and most heavy-duty equipment available. Electrolux is continually updating and refining its product range, and also focuses on hygiene, economics, safety, and after-sales service. www.electrolux-professional.com

On/offline turbine cleaning

Gas Turbine Efficiency develops, makes, and markets systems for gas turbine cleaning with high efficiency, while minimizing impact on the environment by keeping CO2 and NOx levels as low as possible. The GTE concept provides a high degree of atomization of heated water or detergent through specially designed nozzles, operating at pressures of 50-80 bar. The benefits compared to lower pressure systems are improved wash efficiency, optimized use of water/detergent, and use of the same nozzles for both on- and offline washes. The company's latest system is designed to minimize the need for revenue-losing, unscheduled shutdowns, i.e., necessita-ting an offline wash. The new system allows the turbine to be washed at part or base load without putting the operation at risk – and again, with consequent savings in water and components. www.gte.se

Riser/moorings analysis

Glisco Optekon provides OCED cost-effective design software to optimize design of the riser/floater/mooring system interaction for FPSOs. This software allows the user, for instance, to design a fatigue optimized floating system with steel catenary risers in deepwater. www.optekon.com

Semisubmersible design

GVA Consultants, one of the world's leading designers of semisubmersible platforms, has designed more than half of the purpose-built floating production units around the work, in addition to a large number of drilling and accommodation units. Currently, the company is engaged in four newbuild projects: Thunder Horse and Atlantis for BP, Kristin for Statoil, and Khazar for NIOC. www.gvaconsultants.com

Winch performance

Hagglunds has been working with manufacturers and operators of winches to optimize applications for 40 years. The Hagglunds name is known for per-formance and reliability, particularly with mooring and lifting applications. Typical features of the company's winch drives are: high power (up to 1.2 mw); accurate, constant tension at low and even zero speed with very high mechanical and starting efficiency; no stick-slip effects; strong low-speed performance, and low inertia, providing highly responsive controls. www.hagglunds.com

Hot isostatic processing

Metso Powdermet has won several major contracts from the offshore industry in recent years. HIPed PM Near Net Shape products are supplied from the world's largest hot isostatic processing facility, in Surahammar, Sweden. Main applications are pressure vessel items such as manifolds for topside and subsea installations, valve bodies, swivels, eye-pieces, and large wall thickness fittings. Material grades used are primarily high strength stainless steel: ferritic 12%Cr, 6Mo austenitic and 22-25%Cr duplex ferritic/austenitic grades with high corrosion resistance. Products are made in sizes up to 15 tons, 1:2 m OD and 2.8 m long. www.powdermet.com

High-density concrete

Minelco uses the unique properties of magnetite to produce MagnaDense, a high grade, natural aggregate with high density. MagnaDense is used as loose ballast or aggregate to produce high-density concrete. Due to its high specific gravity, the product is suited to ballasting concrete constructions such as rigs and caissons. Concrete produced using this material also brings advantages for pipe coatings and other subsea constructions. Other applications include coastal protection, radiation shielding, and counterweights. www.minelco.com

Airborne sea/spill surveillance

Swedish Space Corp. has developed a new generation of its airborne surveillance system. The MSS 6000 could be a useful tool for offshore operators as well as for traditional US Coast Guard users. In this new system, not only radar and infra-red images, but also AIS and satellite transponder data is integrated into the electronic situation awareness map to give a detailed and up to date overview of conditions on the sea surface. This overview is transmitted via a data link to the ship or shore to provide real time management information. www.ssc.se
