An increase in demand for exhaust gas cleaning systems is anticipated as a result of this USA regulation.
covering engine and fuel standards which are similar to those set out by International Maritime International (IMO) under Marpol. One of the key features of the new rule is acceptance that USA flag ships and vessels operating in USA ports can meet new sulphur emissions targets by employing exhaust gas cleaning devices, better known as ‘scrubbers’. An earlier draſt had suggested that the targets would have to be met by using low sulphur fuels alone, but the EPA has had a change of heart following

evaluation of the technical options available, the SPB LNG tank technology has been retained for the storage of liquefied gas. Te choice was driven by considerations such as accessibility for maintenance, robustness, and therefore long-term offshore life availability, and re-deployability. Tis hull can be adapted to also suit
the requirements for floating storage and regasification units (FSRU) for which demand is expected to grow with the LNG market. An agreement has now been signed
he USA Envi ronmental Protection Agency (EPA) has recently announced a new rule
between SBM and IHI shipyard of Japan, for the detailed engineering and the further construction of LNG hulls. SBM has funded IHI to develop the basic design of a 230,000m3
multi-function
hull. Te long-term agreement provides that IHI offers its construction capacity at the Aichi Works for an early project,

operating in the proposed Emissions Control Area (ECA) 200 miles off the USA and Canadian coasts. Te regulation is therefore expected to significantly increase demand for scrubber refits on vessels trading to and from North America. Following the USA decision to accept
scrubbers as a viable means of reducing emissions, the UK-based company, Hamworthy Krystallon, has become the first non-North American company to be awarded accreditation as a manufacturer of an ‘emerging technology’ by the United
Capabilities Te Linde Multi-stage Mixed Refriger- ant (LiMuM) process has been selected for the liquefaction system based on its thermodynamic efficiency, robust design, compactness, and proven performance. Te FPSO facility will be able to treat, fractionate, liquefy, store, and export the LNG as well as any by-products from the gas field production, such as LPG and condensates. The nominal size of the developed
facility provides an output of 2.5MM tonnes per year of LNG which, therefore,
is typically suitable for fields in excess of 1tcf recoverable gas reserves. The comprehensive topside design will enable the process of almost any natural gas composition. Linde and SBM are both confident that
States’ Environmental Protection Agency (EPA).Te primary goal of the emerging technology programme is to support the early deployment of new technologies that will reduce emissions from the existing fleet. Hamworthy Krystallon suggests that
there is a strong upcoming demand for this type of facility and the best resources of both companies have been mobilised and are working on this project. For SBM Offshore, the objective of
data from operations on vessels already fitted with its scrubber technology confirms greater than 98% sulphur oxide gas removal and up to 80% particulate removal. According to the company it now has a network of global shipyards ready to install the scrubbing system onboard cruise ships, ferries and other vessels. SRCT
this LNG FPSO initiative, complemented by the other products, is to serve the industry with a solution to monetise energy resources that otherwise would be untapped and by doing so, to place the company as a pioneer in this market and to maintain a leading position in the long term, in the same way as it did in the crude oil FPSO lease and operate segment, where it is still a significant player today.
