Gas conversions demand greater corrosion protection

NOA60HS eliminates the risk of anti-corrosion coatings applied with low film thickness

Nippon Paint Marine is advising shipowners and shipyards converting existing oil and gas carriers into storage and production units to ensure their fuel, water and cargo tanks are sufficiently protected from corrosion.

According to data from the coatings’ specialist, reduced dependence on Russian oil and gas is leading to increased demand for ships able to transport and, in particular, store gas at key...

Bureau Veritas conducts successful proof of concept for corrosion detection powered by A.I

Bureau Veritas conducts successful proof of concept for corrosion detection powered by A.I

© Bureau Veritas Marine & Offshore

Paris La Défense, 19 April 2021 – Bureau Veritas (BV), a world leader in testing, inspection, and certification (TIC), has successfully proven the value of deploying its artificial intelligence (AI) solution for corrosion detection during a hull inspection of a water ballast tank on a bulk carrier by an aerial drone. The test was conducted in partnership with the RIT...

Scrubber Market Readies for Rebound Amid Anticipations

The scrubber market is ready for a rebound as suppliers anticipate promising quicker installations and new technologies, says an article published in Riviera Maritime Media.

Scrubbers an attractive investment

Based on various factors, scrubbers can be an attractive investment for shipowners for emissions compliance. Few factors listed are:

  • equipment price, 
  • installation cost, 
  • how many days a ship sails within an emissions control area, 
  • the price differential between HFO and MGO, 
  • fuel...

The hidden risks of biological corrosion

The IVR Association issued an informing paper explaining the hidden risks of biological corrosion and providing additional information on how to avoid bacteria that damage ship bilges; The technical leaflet “Biological Corrosion” is focusing on a number of cases where the issue of leaking engine rooms seems to be more and more common these days.

Accordingly, the phenomenon of leaking engine rooms is mostly caused the water ingress is by very local corrosion perforations. Investigations that...

Gard: Challenges Faced With Improper Scrubber Installation

Marine insurer Gard advises its members that the installation of scrubber units must be carefully monitored in order to minimize errors, reports Maritime Executive.

Scrubber installation to be monitored
  • The issues range from a risk of premature corrosion and potential piping failure.
  • Additional potential casualties from improper workmanship include the possibility of sparking a fire within the unit during shipyard hot work and the failure of poorly-executed shipyard welds during operation.

With...

NRL Pigment Package for Ship’s Color and Gloss Retention

U.S. Naval Research Laboratory (NRL) designed pigment package to slow discoloration of the exterior coating on surface ships is producing early, positive results, reports MarineLink.

What is the issue?

NRL researchers created the pigment combination to satisfy the fleet requirement for the Navy standard “haze gray” paint that will remain color stable for longer than current coatings. 

Many paint manufacturers had produced new coating technologies that solved a variety of other problems, such as...

ABS brings artificial intelligence to vessel corrosion

The American Bureau of Shipping recently collaborated with Google Cloud and software engineers SoftServe to use artificial intelligence (AI) models to detect levels of corrosion and marine coatings breakdowns on brown- and bluewater vessels.

The pilot project is aimed at developing image recognition software tools that can examine early signs of degradation in hull structures, to avoid unsafe working conditions, unscheduled maintenance and resulting operational downtime.

The effort demonstrated...

‘Catastrophic structural failure’ caused sinking of Stellar Daisy

Two years after the VLOC Stellar Daisy sank along with almost its entire crew in the South Atlantic Ocean, the Marshall Islands issued the investigation report on the accident, identifying a ‘catastrophic structural failure of the ship’s hull‘ as key cause of the accident.

The incident

On 31 March 2017, the 266,141 dwt, very large ore carrier (VLOC) Stellar Daisy was underway in South Atlantic ocean, on its way from Brazil to Qingdao, China, when it sank about 1,700 off Uruguay. The water depth...

Inadequate maintenance leads towing vessel to sink

The NTSB issued an investigation report on the flooding and sinking of the towing vessel ‘Nancy C’ on Lower Mississippi River, near Dyersville, Tennessee, in March 2018. The investigation identified poor maintenance as key cause of the incident.

The incident

On 6 March 2018, about 1630 local time, the uninspected towing vessel Ms Nancy C was moving and positioning cargo barges while operating in Everett Lake, a tributary of the Mississippi River, when a deckhand discovered water in a void at the...
