Last weekend the Shackleton was forced to abandon the survey in the area around the Schiehallion and Foinaven FPSOs which are to the West of the Shetland Isles due to poor weather.
We then relocated to the Bruce platform to the East of the Shetlands where the weather was more suitable for survey work so the small Lynx ROV proceeded to carry out an inspection of the Bruce platforms risers which is basically a pipe that rises from the sea bed up to the platform to deliver the oil for processing.
Also at Bruce an inspection of 32" ∓ 24" spool pieces was carried out. Spool Pieces are connections between the main pipeline and the risers which are designed to allow for any heat expansion from the pipe.
From the Bruce platforms it was then a 3 hour steaming time to the next location which was Harding.
Harding is a jack up installation which sits on top of a storage tank, The tank is connected to a pipeline which runs to a PLEM (pipe line end manifold) which in turn is connected to an STL (submerged turret loading) that has a floating buoy on the surface and a tanker comes along and picks up the STL, connects it up to the tanker and exports oil for transportation to the mainland. The survey in this area was for the anchor wires to the STL using the large solo ROV.
On completion of the Harding tasks the Shackleton headed for Peterhead for a short port call to exchange clients,collect some spare parts and top up with fresh victualling stores.

Our new Clients include Bluewater Industries , ATP-oil and gas incorporated and Shell.
Our next task was to do a pre-lay route survey between two rigs starting from L6 Well head to G17d- AP Platform a total of 39.5 km.
L6 Wellhead is located about 40 miles to the North of Terschelling in Holland so to arrive there we had a 28 hour transit time from Peterhead.
The purpose of the survey is to ensure there are no obstructions or debris between the two points that would interfere with a pipeline laying project.
Above: (1) Survey start point L6 Wellhead and (2) finish point G17d-AP Platform showing a new platform under construction.
During the Survey a large heavy fishing net was discovered so at the moment we are on the way back to the point where it was found for an attempt to move or recover the obstruction.
That's about all for the Shackleton update so the following photos are of a few routine tasks performed this past week.

And not forgetting the survey crew buried inside the ROV control rooms......

Events this coming week include, protective mattress laying in the Trent Gas Field area and a full Ships Crew change at Immingham on Thursday 14th July which means the end of the four month duty period for Captain John Marshalls team, handing over to Captain Graham Chapmans team who will be on duty until about mid November. So to all the crews family and friends we will see you all in a few days time.
Thanks to Ray Davis for most of the photos again.
