3.1 Mechanism of corrosion of back of upper deck plate The mode of corrosion at the back of the upper deck of a crude oil tank is so-called general corrosion,wherein the steel plate is cor- roded almost uniformly.It has been reported that the rate of corro- sion is generally within 0.1 mm per year.Steel News - AISTNew crude oil tankers of 5,000 dwt or higher are required to use corrosion-resistant steel in the bottom plates and strength deck of the cargo oil tank.The new regulations were enacted to prevent marine pollution from oil spills caused by corrosion problems in oil tankers.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextCargo Tank - an overview ScienceDirect TopicsCargo tank washing.After discharge of cargoes,oil tanker cargo tanks can be cleaned by either hot or cold water,fresh or sea water,or by crude oil washing.Water cleaning machines can be fixed in a tank or may be portable,the portable machine being connected by hose to a deck water main before being introduced through a tank-cleaning hatch

Nippon Steels NSGP-1 Approved for Oil Tanker Cargo

Nippon Steel announced on Wednesday the firms high corrosion resistant steel plate for crude oil tanker,named NSGP-1 (Nippon Steel Green Protect-1),got approval from ClassNK as the world first steel plate that can be adopted to bottom plate of oil tanker cargo tanks with high corrosion resistant performance required by IMO (International Maritime Organization).NYK and Nippon Steel Receive Ichimura Industrial AwardNippon Steel identified that the corrosion was caused by highly concentrated and strong acidic salt water that would separate out from crude oil and accumulate at the bottom of tanks.The company then developed a new steel material,NSGP-1,which exhibited superior corrosion resistance even in an extraordinarily severe environment.Liquid Cargo Tankers - PaintSquareture is similar to that of crude oil tankers.All cargo tanks receive a chemically resistant coating system to protect the steel surfaces from corrosion and to prevent cargo contamination.In bare steel tanks,liquid cargo can impregnate rust scales and pitted areas.While it can be impossible to clean these surfaces with pressure water

Development of Corrosion Resistant Steel for Bottom

Pitting corrosion on the bottom plates of cargo oil tanks (COT) in very large crude carriers (VLCC) is very serious problem.Each tank may suffer up to 1,000 pits,with some reaching a depth of as much as 10 mm.As a result,the workload of repairing such pitting corrosions in periodical dock inspection is extremely heavy.Development of Corrosion Resistant Steel for BottomPitting corrosion on the bottom plates of cargo oil tanks (COT) in very large crude carriers (VLCC) is very serious problem.Each tank may suffer up to 1,000 pits,with some reaching a depth of as much as 10 mm.As a result,the workload of repairing such pitting corrosions in periodical dock inspection is extremely heavy.Corrosion wastage model for ship crude oil tanks Nov 01,2008 corrosion steel plate for cargo oil tank of crude carrier#0183;Brondel et al.has illustrated the effects of the different gases encountered with the crude oil on the overall corrosion rate of carbon steel.The relationship between the corrosion rate and hydrogen sulphide concentration is fitted well to a power function of the following form (see Fig.2) (6) d (t) t = 0.5363 H 2 S 0.3973-1.439,R 2 = 0.987 where d(t)/t is the corrosion rate
