In addition, HHI has won an order to build a third
LNG floating storage regasification unit (FSRU) for Hoegh on 13 February. Te contract for the FSRU is an option exercised by Hoegh from the original contract signed in June 2011. Te contract is for a 170,000m3 LNG FSRU which is scheduled to be delivered by the second quarter of 2014.
Fuel technology Jo flicks a switch
Meeting environmental regulations has been simplified, says Norwegian operator Jo Tankers, aſter it fitted a diesel switch mechanism that allows its ships to easily switch fuels when necessary. Approved by Germanischer Lloyd the JOWA
Technology Diesel Switch DS MKII allows the operator to meet sulphur emissions regulations in both California Air Resources Board (CARB) and Sulphur Emission Control Areas (SECA). Developed by Sweden’s JOWA Technology, the
company claims that the DS MKII Diesel Switch provides a reliable solution that will prevent any short-term or long-term problems for crew, engine, environment and the owner that an incorrectly performed changeover could create. “Since we installed the DS MKII we have been
experiencing very positive results onboard our vessels”, said Jo Tankers’ fleet manager Andrew Hills.
The DS MKII has unique software developed by
JOWA Technology that controls a blend fuel valve and it has an overall architecture that can be adapted to the available space on board. JOWA Technology says that the low-cost investment
for the DS MKII gives a rapid return on investment. “We now know that we meet the strict sulphur levels
requested in the SECA Areas and in other environmentally controlled areas. Tey can be reached both by using the diesel switch DS MKII for a complete change-over or for running on blend fuel. “We appreciate the software feature including the
history log for change-over and/or blend fuel procedures performed,” said Hills.
Bulk carriers Delphin takes delivery of
supramax Owners Delphin took delivery of its fuel-efficient 57,000dwt supramax bulk carrier Aquila in late January from China’s Jiangsu Hantong (HTS) yard. Sea trials confirmed that the vessel can achieve a
14% reduction in fuel consumption as a result of the improved SDARI design. Sea trials were supervised and appraised by class society Lloyd’s Register. Aquila is the first in a series of bulk carrier designs
that have been optimised for fuel efficiency. The efficiency improvements have been achieved by carrying out a number of straight forward changes including: de-rating the main engine, a new propeller design which has been optimised for the de-rated engine, and fitting a mewis duct. “The daily main engine consumption at a speed
of 14knots at ballast, which would have been about 29.4tonnes, is now about 26tonnes and the daily main engine consumption at a speed of 13.5 knots at design draught, which would have been about 29.8tonnes daily, is now about 26.30tonnes. Te engine’s output has been reduced by nearly 1000kW to 8500kW,” confirmed Lloyd’s Register. Ship designers SDARI said that the structure of the
BC57K design has been, “optimised, satisfying the latest requirements in the Common Structural Rules for bulk carriers, especially to accommodate the severe strength requirement of steel coils. Te new ship will be able to load about 54,000tonnes of steel coils during one voyage with little increase of light weight. Now, the vessel also meets the requirements of EEDI-PHASE I.”
After installing DS MKII, Jo Tankers says it has achieved automatically controlled, safe and economical changeover procedures from HFO to MDO and vice versa.
