A seismic shift for the isles
This week marks a milestone for Lerwick Harbour in its involvement with the North Sea oil and gas industry since its arrival in UK waters.
Fifty years ago, two seismic survey ships operating east of Shetland sought shelter in the port. They are believed to have been the first oil-related vessels to call at the start of Shetland’s transformational and ongoing relationship with the industry.
The Shetland Times of Friday 3rd July 1964 reported that the Cedar Creek from the USA and the Runmond III, from Holland, surveying for Western Geophysical on behalf of a British “petroleum” company, had been stormbound in Lerwick the previous weekend. They later headed for Norway.
Lerwick Port Authority’s harbourmaster Calum Grains said: “Oil-related vessels weren’t recorded separately from general ships through the 1960s. Only with increasing activity in the 1970s were they categorised and counted by their types.
“Research by our staff and recollections from the then shipping agent at Hay & Co led to these two vessels which are believed to be the first oil-related ships into Lerwick.
“By way of comparison, at 151 gross tonnes the Cedar Creek is around the size of the port’s current vessel Kebister. The then fairly new stern trawler Runmond III, at 241 gross tonnes, is comparable to a modern local white-fish vessel.
“Seismic ships now calling at Lerwick can be significantly larger – some Ramform vessels weigh in at over 10,000 tonnes.”
Since oil vessels were first categorised in the port’s records in the 1970s, around 40,000 have called at Lerwick which developed as a leading support centre.
Captain Grains added: “No-one could have guessed then what these two vessels heralded for Shetland in oil and gas activity and the impact on the economy and community over the next five decades.
“Or that, 50 years on, development would still be continuing onshore and offshore, with years of production to come – and that we would still be investing in the port to make the most of more new opportunities.”
The offshore industry is a major beneficiary of investment by the port authority which is proposing to spend another £30 million-plus in the next few years. Development over the decades means Lerwick now has almost 4,000 metres of quay, including over 1,300 metres of deep-water berthing, and 130,000 square metres of laydown. Future capital projects will include another 1,800 metres of quay.
