IMO ADOPTS CLIMATE CHANGE STRATEGY FOR SHIPPING
Nations meeting at the United Nations International Maritime Organization (IMO) in London recently have adopted an initial strategy on the reduction of greenhouse gas emissions from ships, setting out a vision to reduce GHG emissions from international shipping and phase them out, as soon as possible in this century.
The vision confirms IMO’s commitment to reducing GHG emissions from international shipping and, as a matter of urgency, to phasing them out as soon as possible.
More specifically, under the identified “levels of ambition”, the initial strategy envisages for the first time a reduction in total GHG emissions from international shipping which, it says, should peak as soon as possible and to reduce the total annual GHG emissions by at least 50% by 2050 compared to 2008, while, at the same time, pursuing efforts towards phasing them out entirely.
The strategy includes a specific reference to “a pathway of CO2 emissions reduction consistent with the Paris Agreement temperature goals”.
The initial strategy was adopted by IMO’s Marine Environment Protection Committee (MEPC), during its 72nd session at IMO Headquarters in London, United Kingdom. The meeting was attended by more than 100 IMO Member States.
IMO Secretary-General Kitack Lim said the adoption of the strategy was another successful illustration of the renowned IMO spirit of cooperation and would allow future IMO work on climate change to be rooted in a solid basis.

ARE ‘SMART BOLTS’ THE THING OF THE FUTURE?
In the future, intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong. This could reduce the risk of human injuries and save cost.
A research team at NTNU in Gjøvik is working to create bolts that send an alert when something is not as it should be or when maintenance is needed. Each bolt must be able to contact a control center, which will receive messages from all intelligent bolts of this type in all installations around the world.
The team working on these wireless bolts includes Professor Michael Cheffena, two fellows and the manufacturer Dokka Fasteners. The vision of the research team is to develop wireless sensors to be installed inside the bolts. If the sensors detect that something is wrong with the bolts, they will send a message to the Dokka Control Center, which will then send a message to their customers. This makes it easier for operators to keep an eye on their equipment and prevent major accidents.
“Many structures like wind turbines, oil and gas installations are subjected to heavy loads. Today’s manual methods for controlling and maintaining bolt loads are very time consuming and costly. So, therefore, developing an effective, common monitoring system is of technical importance,” said Cheffena.
