Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When selecting offshore platforms for supply, it is recommended that companies match specifications based on key technical parameters such as actual operating water depth and bearing capacity. For example, there is a significant difference in structural strength requirements between shallow and deep water projects.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable delivery records in offshore oil and gas development or wind power installation scenarios.
  • For the application of offshore platforms in different scenarios such as exploration drilling and production oil storage, attention should be paid to parameters such as anti-corrosion design and modular expansion capability to adapt to high salt spray environments or long-term berthing needs.
  • When purchasing offshore platforms, it is usually necessary to combine the supplier's industry performance and platform statistical information, such as past project data in the North Sea or Southeast Asian waters, which can be used as one of the reliability assessment criteria.

Knowledge Base

Q

The selection of seamless pipes for offshore wind power platforms requires protection against seawater corrosion, salt spray corrosion, and wave impact. The material selected is 2205 duplex steel pipe or BFe30-1-1 copper nickel alloy pipe. 2205 duplex steel pipe is resistant to seawater corrosion, has high strength, and has strong resistance to wave impact; BFe30-1-1 copper nickel alloy pipe is resistant to marine biological attachment and suitable for pipelines that come into direct contact with seawater. Wall thickness increase

Q

N08028 achieves a perfect balance between corrosion resistance and mechanical properties through the synergistic effect of ultra-low carbon austenite structure and high nickel, chromium, molybdenum, and copper. Its wide application in chemical, marine, energy and other fields is not only due to its excellent performance, but also thanks to standardized production processes (such as ASTM B668) and flexible heat treatment processes. With the development of corrosion-resistant materials

Q

316 stainless steel contains molybdenum element and has a much higher resistance to seawater chloride ion corrosion than 304. It can withstand long-term salt spray corrosion. Adopting 5-8mm thick serrated flat steel (serrated depth 3-5mm), with a spacing of 50mm between horizontal bars, forming a dense anti slip texture, with a friction coefficient of ≥ 0.9, it can still effectively prevent slipping in damp or salt covered conditions. The welding area has been passivated to avoid
