BWTS Retrofit 3D Scanned in 8 Hours

Posted Leave a commentPosted in Uncategorized
As all members of the Maritime Family are always looking ways to minimize downtime, standby and maximize waiting time, we in 24Marine.com have implemented 2 Scanners in our BWTS 3D Scanning retrofit teams. With two scanners and with careful coordination’s we can achieve 40% time reduction in 3D scanning retrofit projects for vessels.

See below few scenarios where we have taste the benefits and time savings:
-Scanning two separate ballast tanks in parallel
-Scanning Pump room and Engine room in simultaneously
-Scanning Main Deck and Engine room in parallel

We have completed many projects with record times between 8 to 10 hours scanning time, while the vessel is at Port or awaiting at anchorage.

 Here our formula:
2 Scanners X 4 Engineers = 8 Hours Ship scanned 

Tips for good 3D laser vessel scanning projects

Posted Leave a commentPosted in Uncategorized
We are always looking to get the best data for our internal and external customers.

While performing 3D laser scanning projects for BWTS and EGCS retrofits, we use few techniques to optimize and standarize our data delirevables.

Tip 01:
– We always orientate the scanner to the same relative direction inside the vessel

Tip 02:
– Whenever possible we progress in the area using clock wise orientation.

Tip 03:
– When scanning inside ballast tanks, we try to mark a reference in the area we are scanning.

Vessel Conditions Surveys without affecting operations

Posted Leave a commentPosted in Uncategorized

We have been performing conditions surveys onboard vessels, for many years now.

One of our main objectives is not to affect vessels-cargo operations during inspections. For this reason is very important to plan, here few details to consider for a Successful condition survey while in port.

– Full contact with the superintendent at least a week before.
– Coordination with Master, (to prepare documents, spaces to inspect, etc) and post-survey comms.
– Early coordination with local Agent, to understand vessel plans (port call, anchorage time, others)
– Once onboard have a pre-meeting with chiefs from all departments and Master.
– Need to understand the vessel plans and priorities, adjust vessel inspection based on that.

Safety pins for CO2 Valves

CO2 Cylinder Valves

In many locations we have detected the misunderstanding on the usage or not of safety pins on CO2 Systems Cylinders Valves.

As per FSS Code Chapter 9. “2.1.1 Any required fixed fire detection and fire alarm system with manually operated call points shall be capable of immediate operation at all times”

There are two types of valves for automatic release CO2 Cylinders:

Type A Valves: For type A cylinder valve, the safety pin acts as a safety device during transportation, installation and testing phases. The pin must be removed to commission the system otherwise the CO2 system is inoperable.

Type B Valves: For type B cylinder valve, the safety pin is necessary to prevent the unintended discharge of CO2 due to vibration and the pin is required to remain in place until discharge of the CO2. Where the CO2 is discharged remotely from a fire station, the CO2 can be discharged without removal of the safety pin.

Surveys during Panama Canal

Posted Leave a commentPosted in Uncategorized

Panama Canal transit time is normally between 10 to 12 hours, this time give Operators, Charters, and Owners the opportunity to perform surveys. Panama Canal Authority has limits on critical equipment tests, enclosed space entries, and any other activities that could affect the vessel operations while in transit.equipment test at the anchorages.

Here below factors we normally take into account before deciding if performing the survey while the vessel is transiting the canal:

  • Panama Canal transit time is normally between 10 to 12 hours, this time give Operators, Charters, and Owners the opportunity to perform surveys. Panama Canal Authority has limits on critical equipment tests, enclosed space entries, and any other activities that could affect the vessel operations while in transit.equipment test at the anchorages.
  • Here below factors we normally take into account before deciding if performing the survey while the vessel is transiting the canal:
  • For surveys that need equipment test, we can use some anchorage time, before or after canal transit.
  • If the vessel is planned to have a stop-over in the lake, it is a good opportunity to check the bridge and decks.
  • Canal transit time is perfect to inspect Engine room areas and interview Engineers.
  • Bunker time before or after Canal is a good time to interview Bridge Crew.
  • Tanks inspections is possible at the anchorages.
  • IHM Surveys is possible during Panama Canal Transit without the need for Anchorage time.
  • 3D Scanning is only possible during Anchorage time and/or port call, as the vibration while the vessel is moving can affect the quality of the 3D Scans.
  • ISM-MLC-ISPS Audits, possible during Canal, and timing the critical equipment test at the anchorages.

In 24marine.com we are looking all options and possibilities to perform surveys, taking advantages of any time available, while respecting regulations and operations limitations.

Remote Inspections with Drones on Ships

Posted Leave a commentPosted in Uncategorized

During 2019 and 2020, many Class Societies have developed guidelines for Remote Inspection Techniques (RIT) using Unmanned Vehicles as Drones and ROV, in order to assess the conditions of the ship and perform hull conditions surveys with reduced human exposure and lower cost.
 
IACS 42 (Guidelines for RIT), shows the details and recommendations for this type of survey, mainly focus on close-up surveys and gauging.
 
The drone inspection is definitely a way to save time and money and to enhance SURVEYORS safety, as many of the inspected areas are high risk and difficult to access safely. With SMART SURVEY system, our marine surveyors never have to risk their lives by climbing to high places or be exposed to hostile conditions to conduct surveys.
 
The maritime industry has the main focus on the capabilities of Unmanned Vehicles to access and navigate the survey areas. In 24marine we have managed to adapt our Vehicles to be able to confirm whether or not the structure contains defects, such as corrosion, pitting, cracking, buckling, or coating breakdown. In the video below, see our vehicles in actions:

Here a summary of benefits of RIT with drones:

  • Reduce risk for surveyors and inspectors, which are not exposed to the risks of working at height nor, necessarily to enter confined spaces.
  • A lot of time-saving during the inspection.
  • Great potential for enhanced quality evidence when assessing the condition of the spaces.
  • Reducing ship’s downtime and optimizing the preparation before the repairs.
  • Reduce the survey costs
  • Improve the efficiency of inspection techniques
  • Reduce the survey time (real-time streaming)
  • Set limits on conventional risk evaluation
  • Ensure a comprehensive risk assessment
  • Are easy to operate
  • Are environmentally friendly

Ultrasonic Hatch Test for Vessels

Posted Leave a commentPosted in Uncategorized

Over 40% of all P&I claims are due to damaged cargo caused by water ingress via the hatch covers. This represents more than USD 40 millions of damaged cargo yearly.
The main cause of cargo damage is non-watertight hatch covers. Cargo damage due to water ingress from hatch covers remain an important part of insurance claims.
This is the reason; Insurers and Clubs require vessels to maintain hatch covers in a waterproof condition. It is also the statutory requirement for as in the International Convention on Load Lines, 1966.
There are different methods for testing hatch covers:

  • Ultrasonic Testing
  • Chalk test
  • Air test
  • Water hose test.

The Ultrasonic test is the only method that generate systematic and objective results, to determine if the hatch conditions are acceptable or not.

How to perform Ultrasonic hatch Testing

Using just a sound transmitter inside the cargo hold and a detector outside, 24 Marine can detect ultrasonic waves coming from the cargo hold. The hatch cover is closed, fully cleated, and battened. The operator then uses the hand-held detector to listen for the ultrasonic waves from the outside, picking up all sounds that pass through the sealing arrangements, vents or cracks.

Before starting the test, our SMART SURVEORS calibrates the receiver for Open Hatch Sound Value (OHV). Then when performing the test, it recommended to use the 10% benchmark.

  • If the sound levels are higher than 10% of the OHV, the seal is not acceptable.
  • If the sound levels received is less than 10%, the hatch covers are in a weathertight condition.
