Transport processing fabrication installation

A variety of assets has been deployed for the transportation. Piles are transported using tugs and barges for the transports from Aalborg and geared vessels from Seville and Aviles. Installation of the jacket foundations comprises four consecutive steps. The piles are driven into the seabed using a specially designed self levelling pre-piling template able to position the piles to the exact tolerances.

The piles are driven by a kJ hydro-hammer. The template and hammer spread are deployed from the Giant 7 converted for the Wikinger Project into an offshore crane barge by installing a t Liebherr crane. Once installed the piles are dredged and cleaned using specialist tools deployed from two DP vessels.

Jackets are installed with one of the Boskalis sheerlegs Taklift 4 with a capacity of t. After installation the annulus between the jacket legs and the piles has been grouted using high strength grout pumped from a grout factory deployed from another DP vessel. After grouting the jacket foundation has been inspected and handed over to the client. A wide range of self-owned vessels have been deployed on the Wikinger project ranging from support vessels, multicats, tugs, barges, a rock dumping vessel, installation vessels and one of our sheerlegs.

In addition various support vessels, tugs and barges were hired on the project. In total some 25 vessels were deployed. Noise mitigation measures are in place during pile driving to meet the strict requirements set by the German Authorities for pile driving in the Baltic Sea.

Three noise mitigation measures have been applied:. Boskalis has proven its capability to execute complex projects to the highest safety and environmental standards overcoming difficult technological challenges using tailor made vessels and equipment.

Generating pipe spools in the Pipe Fabrication shops are the best economic way for reducing site installation costs for big size projects.

All equipment, tools and manpower are available in the pipe fabrication shop and pipe spools are produced with high quality. Pipe fabrication Specification is an engineering documents that provides all guidelines to be followed by pipe fabricators for spool pipe fabrication. The specification for piping fabrication provides the minimum requirement of preparation of detail shop drawings and the fabrication, requirements for inspection and testing.

It lists down all applicable codes and standards. I am a Mechanical Engineer turned into a Piping Engineer. I am very much passionate about blogging and always tried to do unique things. This website is my first venture into the world of blogging with the aim of connecting with other piping engineers around the world.

Dear Mr. Dey, Thank you very much for posting this. Eagerly awaiting for your next post. I am a mechanical contractor and done various mechanical job but specially pipeline.

Regards and Thanks, Surinder Mitra. Mr Dey, Nice information given by you hope you will send next in future the information about flow and pressure.

One of the first and most influential steps in process piping design is material selection. The most common option includes stainless steel, however Inconel, Monel, Hastelloy and other specialty materials may be available to meet challenging constraints.

No matter how complex your process piping system, keep in mind that straight routes are invariably easier to install and maintain. The simpler you can keep your pipe route, the more affordable it will be. What makes sense on paper may be difficult to install in practice, depending on existing equipment, piping, and walls. For this reason, flexibility must be incorporated into the planned pipe route to account for natural imprecision in the installation process.

Just as a solid design allows for the practicalities of installation; maintenance, repair and cleaning must be considered. To facilitate proper upkeep, consider breaking longer sections into shorter, more manageable pipe sections.

Doing so makes it easier to disassemble a localized portion of the piping for repairs or upgrades. Similarly, consider how the piping will drain before being serviced, and ensure that valves are easily accessible. Failure to consider these factors can unnecessarily lengthen the maintenance process, all while inconveniencing and potentially endangering technicians. Functionality must be the core concern when developing any piping system.

The specific application will dictate the appropriate suction requirements, pipe friction, insulation, and control valves for the system.
