“Shore supply to rigs provides a huge improvement in saved CO2 and NOx emissions. We have roughly calculated that a rig will save 10 to 15 tonnes emissions per day. This represents an annual saving of 4,500 tonnes of emissions”. CCB Project Manager, Sveinung Vethe CCB Project Manager Sveinung Vethe A better tomorrow is driven by drives Docked oil rigs spend large sums on diesel power generation and normally represent major local CO2 and NOx emissions, when parked at Norwegian yards. However vessels visiting Coast Centre Base in Norway now win huge power savings thanks to a shore supply system developed and delivered by SEC and Frekvensomformer.no. By closing down their own generators they save up to 5,000 litres of diesel every day. And the benefits don’t stop there. The air is cleaner and the port is quieter, too. The shore power system is a popular choice amongst vessels harbored at CCB. It offers very competitive power prices, as well as the benefits of the fuel savings. Norway enjoys very low elec- tricity prices due to its large hydroelectric power stations. This helps to make the shore power system an attractive alternative to diesel generators, even in periods where fuel prices are low. At quayside or on deck The shore power container is very flexible. It can either be placed on the deck of the rig or on the quay side. The shore power supply container is typically placed on the deck of a semisub rig located at CCB while it is waiting for the next contract. The alternative to supplying the rig from shore power would be to operate the rig on its own generators – which consume approximately 5,000 litres of diesel daily. The shore power supply can thus save a lot of local pollution in the port area of Ågotness – while also saving money for the vessel owner. CCB Project Manager Sveinung Vethe explains: “We have the capacity to supply one rig, currently the COSLPioneer, with clean shore power. In the future our goal is to expand capacity to supply all rigs with clean Trial before purchase Initially CCB rented a shore power supply container from SEC and Frekvensomformer.no to get some experience with the technology. The feedback from their customers was very positive – so they decided to invest in their own transformer substation for shore power containers from SEC. As well as purchasing the shore power container itself, a new substation and larger power cables were required Therefore in order to establish the shore power supply, CCB had to invest in improved infrastructure. A range of the shore power supply systems from SEC and Frekvensomformer.no. “We have the capacity to supply one rig, currently the COSLPioneer, with clean shore power. In the future our goal is to expand capacity to supply all rigs with clean power – so we will definitely invest in more systems in the future”. CCB Project Manager, Sveinung Vethe 2
