|09/01/09||0500||Depart home by taxi and proceed to LCY airport.|
|0615||Arrive LCY, check in to VLM flight to Schipol|
|0800||Depart on KL210 to Achipol.|
|1020||Landed at Schipol, cleared inwards, ticket purchased for train to Roermond.|
|1250||Arrive Roermond and check in to nearby hotel, taxi to Sif Yard|
|1320||Arrive at Sif yard, meet BartOverbeek the project manager and RoelCorstjens the Sif QA Engineer. Initially we go through the holds raised by our TRN 37 Ra.
The loads imparted by the monopiles and TPs to the deck of the barge La Paz were accepted to be within the designed max of the barge for practical purposes but these are to be officially quantified with support documentation from the barge owners. Loads under the monopiles at the support points were reported as being 21 tonnes per m2 and under the TP 18.80 tonnes per m2. The supports are placed at the barges solid floors so these loadings should be acceptable.
Minimum UK clearance at Roermond will always be greater than 1.2metres.
At Kats clearance will be greater than 1 metre (Tidal curves for the ports were sighted at this meeting).
The barge trim was also addressed in that it will be less than 0.5 metres.
Mooring arrangements at Sif and Kats were discussed. I impressed on them that it is normal practice to submit a mooring plan with line loads included. At Sif and Kats the barge will be moored in barge special ‘barge havens’ that protect the barges from the effects of current and to a large extent, wind (especially at SifRoermond).
Total cargo load for the barge on this first transportation is quantified at 1106.8 tonnes. The barge’s deadweight capacity is 3299 tonnes.
|1400||Have a conducted tour of the construction halls. Crane and rigging certification is sighted, and appeared in acceptable order. Cranes and lifting slings appear to be in good order.|
|1425||Board the barge La Paz which is moored by 30mm mooring wires to hand cranked winches on the barge deck in Haven 9 at Sif. It is already loaded with three Transition Pieces and two monopiles.
The dunnage is sighted as being as per the loadout drawing (as per procedures QP 060 B2021 1 but amended to include the TPs). The barge is a recent build 2006 and appeared in good order. No damage or corrosion is noted. The bilge wells sighted as clear.
|1500||Return to offices, sight KATS crane and lifting equipment certification (copies). All appears to be in order.|
|1545||Last monopole (MP09/A7) is rigged ready for lifting, C of A LC26378/NDC/RGH issued.|
|1613||Loaded onto the two monopiles previously loaded.|
|1615||Barge settled, draft aft noted as 1.95 metres.|
|1700||Walk back to hotel for the night.|
|10/01/09||0845||As arranged previous day, walk to Sif yard and meet with Bart Overbeet. Overnight an email has come in from Naval Sondhi with some queries. I am asked by Bart Overbeet to go through them with him. I responded by indicating that although this (current) transportation was likely to be deemed acceptable (by me) each point should be formally responded to the client by Sif.|
|0910||The pusher tug for the transportation is the ‘Taurus’ which had arrived at the yard overnight. I witnessed it manoeuvring a similarly specified (to la Paz) barge very adroitly at another Sif haven (at the same yard) and then boarded it. Certification was not available but I was given a tour of the vessel including the machinery spaces which were very clean and in good order. The tug can control the barge’s bow-thruster remotely via a telemetry cable.
The crew were very experienced and reported that the minimum underkeel clearance through out the 30 hour transport to Kats would be at least 3 metres. Draft of the tug was 2.2 metres.
The three monopiles will be discharged at Kats on Monday and then the barge will proceed to Hoboken (near Antwerp) which is a Sif facility to discharge the TPs. There the TPs will be coated.
Weather conditions for the transport were forecast to be cold but benign with a moderate Southerly wind expected at Kats on Monday.
|1035||C of A LC 26378/NDC/RGH issued for sailaway. Taurus manoeuvres the Barge (connected to the barge’s bow) clear of the Haven and moves it downstream to moor it alongside another barge which is moored to the shore. Once done, the Taurus then connects to the stern of the La Paz in pusher tug configuration, un-moors it and proceeds on passage.|
|1050||Make arrangements to meet Sif representatives at Kats on Monday morning. Informed that the intention is to stow the monopiles on gravel aggregate dykes.|
|1120||Walk back to hotel. As I have to be at Kats first thing on Monday morning there is nothing to be gained by returning to the UK today and then flying out again tomorrow in readiness for the early Monday attendance.
Thus I make arrangements to travel to Vlissingen (where there are numerous hotels) tomorrow and travel to Kats on Monday morning.
|11/01/09||0959||Commence rail journey from Roermond to Vlissingen.|
|1320||Arrive Vlissingen, taxi to hotel, check in.|
|12/01/09||0550||Check out of hotel, taxi to station.|
|0614||Commence train journey to Goes.|
|0635||Arrive Goes, wait to be collected BartOverbeek.|
|0720||Arrive Hoondert Yard at Kats. Barge and Taurus are secured in the KatsHaven, moored alongside a similarly specified barge to La Paz.|
|0730||Meet HansFilius who is Sif’s local representative. We together inspect barge mooring arrangement, Gravel dykes and crane lifting grommets. The man in charge of the Kats operation is the owner MarcelHoondert.
The dykes are approximately 1 metre high (levels checked by attending surveyors), 6-7 metres wide at the base and 30-40 metres long.
|0820||First monopole lifted from barge.|
|0845||Monopile landed on dykes (two of), allowed to sink into aggregate, sinkage noted at less than 5 cm. By drawing, a maximum depth of 50cm would be required to achieve support over 90 degrees (a quarter of the circumference), so monopole is lifted clear and the dykes are pre-shaped’ ready to receive the pile. Pre-shape is 4.3 metres long by 2 metres wide.|
|0912||1st Pile (MP09/A7) landed in pre-shapes, weight off, no settlement noted.|
|0915||Lifting grommets clear.|
|0945||2nd monopole lifted from barge. Noted that barge lists approximately 5 degrees at this point.|
|1105||2nd pile into pre-shape, no settlement noted.|
|1130||3rd Pile lifted from barge.|
|1220||3rd Pile into preshape. Informed by Sif that next week (19th) they will double stack piles onto the first layer (except for outer most pile) and ‘monitor the behaviour’. I suggest that I attend for that ‘trial’.|
|1240||Sif reps drive me to suburbs of Dordrecht where I catch a local train to Rotterdam at 1345.|
|1428||Catch train from Rotterdam to Schipol.|
|1855||Depart on VLM flight to LCY|
|1915||Arrive LCY, taxi to Margate.|
