There is a regulatory and environmental imperative to reduce emissions from shipping which accounts for 2.4 per cent of global CO2 emissions (ICCT 2015), 13 per cent of SOx emissions and 15 per cent of global NOx emissions (Guardian 2017). The options are to change fuel type which requires considerable time and development work, or in the short term to encourage ‘slower sailing’. According to a Transport & Environment analysis a ship speed reduction of 25 per cent leads to a reduction of fuel consumption and emissions of 58 per cent. But to maintain the return on capital and ‘slow sail’ efforts must be made to cut the turnaround time in ports. To cut turnaround time there are two options being to add more expensive cranes, or to multi-lift containers at much lower cost. To lift more containers there are two options. For laden containers stronger cranes, reinforced quaysides and tandem spreaders are required. But a quicker and much less expensive option is to use BLOK Spreaders for empty container moves which represent 24 percent of all containers moved (higher or lower in different locations depending on the balance of trade) which can be managed with existing cranes and quaysides. To achieve four times faster cycle times for the STS cranes BLOK Trailers (which are double width trailers) can be used to replace four single trailers, again increasing efficiency. A barrier to speeding up the process is the manual removal of twistlocks and that remains one of the most hazardous aspects of container handling. The more pricey option is to use two automatic twistlock removers but again there is an opportunity to make savings with a BLOK Trailer and BLOK Rig. The final piece of the jigsaw is to guarantee the strength of tandem lifted containers and their liftlocks which is also addressed by using the BLOK Rig and BLOK Cert, a certificate that confirms the testing of the lifting container.
The System currently comprises five products which can be used in a ‘pick and mix’ way for different handling systems or all together for maximum efficiency
