Project: A new drilling platform, type WC13-6 (J275)

· Owner: CNOOC Ltd., Zhanjiang / China

· Technical Engineering and construction platform: CSE Shenzhen, Shekou Shenzhen / China

· Application protection: Shen Zhen Yue Yang Company, Shenzhen / China

· Completion date: August 2013

· Ceramic Polymer partner and technical consultancy in China: Guangzhou Petrochemical Technology Co. Wwin Ltd., Guangzhou, PRC 510160

There is a risk of corrosion in the situation above and below average water offshore constructions. To obtain a durable corrosion protection was applied directly onto the metal substrate, "Ceramic-Polymer SF / LF-SRB."

 

Exista un risc mare de coroziune in zona situatia deasupra si sub nivelul mediu de apa a constructiilor offshore.  Pentru obtinerea unei protectii anticorozive durabile, a fost aplicat, direct pe substratul metalic, produsul „Ceramic-Polymer SF/LF-SRB” .

 

Advantages and properties "Ceramic-Polymer SF / LF-SRB"
 

·Excellent resistance to sea water

·Very good abrasion resistance

·The effect of stopping fouling due to neutralizing elements that endanger the material surface Patent-No. WO2011 / 000 339 A2· Apply the product is very simple, it is performed by spraying

·No solvents

·Easy to clean

· ISO 20340- meets the requirements recommended protection systems for offshore structures

· Test involving impact on the ecosystem, according to GB 18420.1 + 2-2009 (China Standard)

 

What is needed to protect the pillars of the drilling platform?
 

In the tidal area and impact area with water, the oxygen content of seawater is higher, influenced by currents and waves. Therefore, the process of corrosion is accelerated by the constant movement of the water. Furthermore, there are cases of extreme mechanical abrasion caused by the permanent flow of water. So special protections is of crucial importance in this sector. In areas with deep water, cathodic protection anodes provide adequate against corrosion damage.

· Easy to clean

· ISO 20340- meets the requirements recommended protection systems for offshore structures

· Test involving impact on the ecosystem, according to GB 18420.1 + 2-2009 (China Standard)

SRB Series: Limiting a buffer integrated using biocides capsules

Active biocides contained in this product is encapsulated in the polymer matrix. At first, the product has no antiseptic capacity and its exposed to external factors.

During interaction with microorganisms, it releases encapsulated biocides toxic and causes a local effect. Protection product is not affected by the permeation of the organisms. "Ceramic-Polymer SF / LF-SRB" ensure a smooth surface without discontinuities, which can be cleaned with ordinary equipment.
 

"Ceramic-Polymer SF / LF-SRB" China—meeting the  standard toxicity test criteria according to GB 18420.1 + 2-2009
 

· Institute: National Oceanic Administration, Division South Sea

· Toxicity Test: and shrimp gobies

· Test method: monitoring 20 fish in five different cups, which bear protection, with a water temperature of 25 ° C. The test period lasted 96 hours (Gobies) and 72 hours (Brine Shrimp)

· Result: Protection does not influence the life of fish and shellfish

Ceramic products offshore applications Polymer- April protection systems extensively tested met the criteria, according to ISO 20340.

One of the most important standards in offshore protection is ISO 20340 anti-corrosion (performance requirements for protective paint or similar offshore structures).
 

 

Tested products:

·         Ceramic Polymer SF/LF

·         Ceramic Polymer SF/LF-3

·         PROGUARD CN 200

·         PROGUARD CN 100 iso

 

Test procedures in accordance with ISO 20340, cycles of 25 weeks (6 months), following the next model:

· 3 days of simulated weathering, UV radiation and evaporating water every 4 hours

· 3 days of continuous spray of salt-based spray (5% solution based on sodium chloride) at a temperature of 35 ° C

· 1 day the product is exposed to extreme thermal shock, placement in a room with a temperature of -20 ° C

Only very resistant products can meet this requirement. "Simulation sea conditions" with UV radiation, permanent humidity and spraying a salt based substances keep the material specifications. The main challenge is represented by extreme thermal shock. The remaining water freezes inside the product tested. In most cases, this leads to detachment of the edge protection.

Polymer ceramic product showed no defects such as bumps, cracks or peeling. The four products shows a very good adhesion capacity. There were no traces of corrosion between the metal surface and protection applied.
