Cargo Tanks – Drone Inspection

Drones and UAV offer a very real solution for the inspection of confined areas, such as tanks / cargo holds. Traditional inspection of these tanks is a laborious, expensive and poses many potential risks. The use of a drone revolutionises the time  needed and the the safety of cargo tanks and cargo holds inspection.

By performing tanks  and cargo holds inspections using drones the specialist (24marine.com) can check the the real time conditions of places that are not accesible by normal human conditions.

A drone can be quickly deployed to capture images and video to allow asset inspectors to view all internal spaces. This includes fitting pipes, wall and bulkheads junctions, welding, structural members, without the need for workers to spend time in a highly hazardous environment,  workinng at high.

Industry statistics shows that 98% of the costs are related to HSE and preparation, only 2% to the inspection itself. By removing the need for staging, scaffolding, downtime and the time is taken for humans to enter confined spaces leads to a cost reduction that amounts to hundreds of thousands of dollars


Traditional cargo tank inspection takes days to implement. Tank inspections carried out by a drone can take as little as two hours per tank. or cargo hold.

LESSONS FROM THREE VESSELS COLLISION AT ANCHORAGE

Details on the attached file.

Lesson Learned:

  1. Port administrations need to have an increased safety distance when the weather conditions are not favorable.
  2. During adverse weather conditions is recommended to have the engine on standby mode, since once the vessel start develop momentum it close to impossible to stop without engine.
  3. The anchor performance is heavily defendant on the amount of chain deployed, in order to have the anchor on the correct position to bite the floor.
  4. During heavy weather conditions the position monitoring need to be more often than in normal situations, there in the market many GPS for bridges with anchor monitoring alarm, that give officers on watch a ring when the threshold is passed.

This Incident was taken from Marine Accident Investigation Branch from UK.

Incompleted Maintenance the Cause of Vessel Fire (U.S. NTSB)

Interesting investigation from U.S. National Transportation Safety Board (NTSB).

The U.S. NTSB has determined that an insufficient preventative maintenance program and lack of guidance for responding to engine high-temperature conditions, led to the January 14, 2018, fire on board the small passenger vessel Island Lady, in the waters of the Pithlachascotee River, near Port Ritchey, Florida.

 

The NTSB’

s investigation determined:

  • • Tropical Breeze Casino Cruz’s lack of guidance regarding engine high-temperature alarms led to the captain leaving the port engine idling, rather than shutting it down, leading to the fire.
  • • The lack of a requirement for a fire detection and suppression system in an unmanned space containing engine exhaust tubing prevented early detection of, and a swifter response to, the fire in the lazarette.
  • • The captain’s decisions to return to the dock and to subsequently beach the Island Lady were prudent and increased the likelihood of survival for those on board.
  • • The failure of the port engine’s raw-water pump led to overheating of the engine and exhaust tubing.

    • The raw-water pump’s failure resulted from Tropical Breeze Casino Cruz’s failure to follow Caterpillar’s recommended maintenance schedule.

  • • The Island Lady’s crew had insufficient firefighting training.
  • • The use of plastic tubing on local tank level indicators and lack of automatic shutoff valves on the fuel tanks resulted in the release of diesel fuel, which contributed to the severity of the fire.
  • • The U.S. Coast Guard did not correctly assess the Island Lady’s fuel system’s compliance with applicable regulations during an inspection of the vessel.
