Semac 1 at the Murchison

I took this pic on final approach to the accomodation barge, Borgland Dolphin I think. Despite the pic I have absolutely NO recollection of this barge, Semac 1, whatsoever. Or maybe it was only there in a pipelaying mode and not accomodation. I was one of a small number of men who were sent onto the Bergy worker crane barge to live. It was out of this world and when the authorities discovered just how good it was, we were taken off and it was used for Conoco staff only. I remember a stainless steel bucket full of dressed crab. It was also fitted out with the first sauna any of us had ever seen. This would be August/September 1980.

The Dolphin was relocated to other side of platform to let the lay barge come in and start the oil export pipeline. It headed off in an arc towards the Thistle platform.

The SEMAC was built to build the FLAGS gasline and that was it's life over. It did it in record time with several months of contract left over and it then laid some of the interfield Shell pipelines before being bought by Brown and Root and continuing for many more years in the North Sea. She is still called SEMAC and is operated by Saipem currently in Singapore awaiting work.

The summer of the HUC was hot and they had to ban guy from swimming off the back of the Bergy Worker after work. Hard to believe in this day and age.

I worked at the shipyard where she was built and signed on to put her in operation in the North Sea.

I started on the Semac1 in 1982, Joe Wray was my Supt, best barge I ever worked on, my father later became Supt, other Supt included Red Monday, Joe Evans & John Sullivan, I don't know where "Semac1" ever got her name, she was to us at B&R the "BAR420".

The legendary semi submersible pipelay barge SEMAC 1 was beached at Alang on 8th January 2016 for disposal. She was built to do one job, lay the 36" SHELL EXPRO FLAGS (Far north Liquids and Associated Gas System) gasline from the Brent Field to St Fergus gas terminal which paid for her construction. She ended up working until last year, 40+ years. She was built for Shell Expro and J Ray MacDermott from which her name was derived.

Two innovative vessels, the Regal Service and the Royal Service were built at the same time by Zapata Offshore (by Ulstein?) to supply her with pipe from three stacks, they had two moving carriages that moved the central and forward stacks aft to allow the cranes to pick up pipelengths in the safest, most workable way. The FLAGS job paid for them. Royal Service was scrapped some time ago but Regal Service is now Energy Miner and is a suction dredger chasing minerals and gems from the South American seabed.

SEMAC 1 had sister semi-submersible laybarges, Santa Fe Choctaw I and II (her forebears) and Viking Piper (now LB200), Castoro Sei followed, she is still working.

I was told it was a join venture of Shell Exxon Mobile Amoco Conoco.

Added by N Lewis Bodden on 07 December 2017.
I think that was the original group but Mobile, Amoco and Conoco pulled out to concentrate on their own discoveries including the Beryl, Hutton and Murchison fields respectively.
