Helemaal waar Leo !.
Maar op die productie platforms staan kranen met een iets mindere hijscapaciteit...…………... :lol:

Op de rigs van Zapata Offshore waar ik 5 jaar op gedraaid heb, werden kranen gewoon gebruikt. Ik kan me daarvan geen enkele test herinneren. Dat waren LeTourneau elektrische kranen, die maximaal 60 ton konden hijsen, afhankelijk van hoe ze gerigged waren. Doorgaans was er 1 exemplaar dat voor 15 ton was gerigged, daar was het snelst mee te werken en die werd standaard gebruikt om de suppliers mee te behandelen.
De 2 anderen waren voor 45 ton gerigged.
Maar alle cranebooms hadden al knikken (wegens niet al te voorzichtig werken, waarschijnlijk) maar niemand die zich daar echt druk om maakte.
OK, dat was tussen 1973 en 1978, en het zal best wel veranderd zijn, maar er werd meer aandacht geschonken aan 'Safety Pays" d.m.v. instruktiefilms, die je dus MOEST bekijken. En verder was het behalen van bonussen door zoveel mogelijk "non-lost-time days" te halen reuze belangrijk. O god, als je zonder hard-hat rondliep aan dek. De mijne, een alu-cap van MSA, ligt nog altijd als trofee hier thuis :mrgreen: Veel van die Yanken droegen nog altijd die "tropenhelm-modellen", met een rand rondom. Die waren toen al officieel niet meer toegestaan...

Dat heb ik in de jaren 1977 / 1978 bij Amoco wel anders meegemaakt Louis.
Daar werden die craneweights dapper het veld rondgesjouwd. Dat was in het Leman- en Indefatigable field wat vanuit Great Yarmouth verzorgt werd. Dat was nog in de tijd dat ik bij Smit Lloyd voer. Long time ago…………... :wink:

Ik moest ff zoeken, maar ik had er tenslotte ook nog foto's van. Ik vraag me af of je tegeswoordig nog zo met kranen kunt werken:

Maar bij ons werden ze gewoon zo gebruikt, alhoewel niet voor 60 ton :mrgreen:

Het lijkt wel alsof die crane boom een keer achterover gegaan is...…………... :roll: :!: :idea:

Johan Sverdrup living quarters topside ready for sail-away

With 560 beds the Johan Sverdrup living quarters topside is the largest of its kind in Norway. The fourth and last platform for the first phase of the giant project is now ready for sail-away from Kværner’s yard on Stord to the Johan Sverdrup field, where it will be installed in a single lift.

“This is an important day for Equinor, the Johan Sverdrup partnership and the Norwegian continental shelf (NCS). This is the last platform in the first phase of the project development, and the completion of the living quarters topside takes us one significant step closer to the start-up of Norway’s big source of income for the next 50 years,” says Arne Sigve Nylund, executive vice president for Development and Production Norway.

The Johan Sverdrup field – owned by license partners Equinor, Aker BP, Lundin Norway, Petoro and Total – is expected to provide value and revenue to the Norwegian state and society of more than NOK 900 billion over the field’s life.

A joint venture between Kværner and KBR was awarded the NOK 6,7 billion contract in June 2015 for constructing the Johan Sverdrup utility and living quarters topside. Leirvik AS was assigned to construct the living quarters modules for the platform. At peak, more than 2000 people have been involved in constructing the platform.

On 15 February this year the joint venture formally handed over the topside to Equinor, just as planned more than 3 ½ years ago. One month later, after further preparations, the living quarters topside is now ready for sail-away to the Johan Sverdrup field in the North Sea where it will be transported on board the lifting vessel Pioneering Spirit.

“Kværner, KBR and Leirvik have delivered a high-quality platform on time and cost. As regards health, safety and environment, the project had a few incidents in the early phase. But the way our suppliers have turned this around has been commendable, so the overall results also in this area have been good,” says Trond Bokn, senior vice president for the Johan Sverdrup development.

“The platform’s high quality and degree of completion at the moment is vital to be able to start field production as planned in November this year,” says Bokn.

“This is perhaps the closest to a «plug-n-play» platform of this size we have ever seen, proving that the joint venture in collaboration with Leirvik have delivered an excellent product,” says Aud Hove, Equinor’s project manager for the utility and living quarters topside.

«This is also a result of the good collaboration and high quality in execution which the project has had since day one. We’ve met every milestone as originally planned, which is quite unique,” says Hove.

The high degree of completion has been achieved by, inter alia, use of the Pioneering Spirit lifting vessel. The vessel’s ground-breaking lifting technology enables completion and testing of bigger topsides onshore before they are installed in a single lift offshore. Carrying out the work onshore instead of offshore leads to major savings and reduced health, safety and environment risk.

The single-lift installation technology was introduced globally during the installation of the drilling platform on Johan Sverdrup last summer.

Now the vessel will be put to work again, first by lifting the 26,000-tonne processing platform for Johan Sverdrup which according to plan will occur in the next couple of days, before the vessel returns to Stord to pick up the 18,000-tonne living quarters topside.

At the Rosenberg WorleyParsons yard in Stavanger yesterday Equinor and the Johan Sverdrup partners celebrated that the two last bridges and the flare tower for the processing platform were ready for sail-away to the field.

With this, Johan Sverdrup is ready for installing the five last pieces constituting the first phase of the giant project puzzle.

Jan De Nul Group's newest jack up vessel 'Voltaire' will be equipped with Huisman Leg Encircling Crane.

Huisman has been awarded a contract for the design, engineering, construction and delivery of the main crane on Jan De Nul’s newest offshore wind turbine installation vessel ‘Voltaire’. The crane will be unique in its size, capacity and novel features to allow efficient installation of the next generation offshore wind turbines.
JDN 1.jpg

The vessel will be built by COSCO Shipping Heavy Industry in China and the Huisman crane will be built in Huisman’s own production facility in Xiamen, P.R. of China and installed at the shipyard. With an unrivalled crane capacity of over 3,000 tonnes and an evenly unrivalled lifting height, this jack-up vessel will be able to support the renewable energy industry to build the future wind farms at sea.

The global offshore wind industry is developing the next generation of offshore wind turbines. These turbines can be more than 270 metres high and are fitted with blades of 120 metres long. Offshore installation vessels currently available on the market are facing increasing difficulties to install these types of turbines due to the turbines’ sizes and installation heights, as well as the ever-increasing foundation dimensions. With this new Huisman-crane Jan De Nul is ready for future developments in the market.

The Voltaire will be equipped with the biggest leg encircling crane ever installed on a wind turbine installation vessel and together with its flyjib will have the highest lifting height in the world. Since 1984, Huisman has successfully delivered more than 224 heavy lift offshore cranes with capacities ranging from 300 up to 10,000mt. This extensive track record in building novel solutions provides the basis on which Huisman is capable of successfully delivering step-changing lifting technology. Primary examples of this are Huisman’s unique segmented slew bearing design, significantly reducing the weight of the crane, and the crane’s fully electric drive system, which was first introduced in the 1980’s.

This contract is the second project in a row between Jan De Nul and Huisman following a project to develop and produce the world’s largest monopile gripper in a record period for Jan De Nul’s Vole au vent wind turbine installation vessel. This project was awarded mid 2018 and will be delivered in the upcoming months.

Joop Roodenburg, President of Huisman: “As the next generation wind turbines are becoming bigger and bigger, we keep on pioneering to develop novel and innovative solutions to install these turbines. We are therefore extremely happy with the confidence and trust that Jan De Nul placed in Huisman by awarding us with this second contract.”
