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

Posted Leave a commentPosted in Uncategorized

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.

3D Laser Scanning for Boats

Posted Leave a commentPosted in Uncategorized

In Naval architecture and marine engineering, 3D documentation is used to support design, construction and new system installations on-board vessels. It provides designers and planners a helpful tool for collecting accurate documentation to create 3D models of the actual vessel configuration.

Laser scanning adds great and easy flexibility, with millimeter precision space and surface geometry, to prepare and plan designs in a digital twin.

WHAT IS IHM (Inventory of Hazardous Material)?

Posted Leave a commentPosted in 24marine, Hazmat, IHM, Panama Canal

IHM is a list that provides ship-specific information on the actual hazardous materials present on board, their location, and approximate quantities onboard vessels.

The purpose of an IHM survey is to provide ship owners, managing agents, crews, engineers, and workers with a management report of all the hazardous materials which, are on-board the vessel.

The main materials that the IHM survey covers:

  • Asbestos
  • PCB’s
  • TBT’s
  • ODS.
  • PCT
  • PBB
  • lead in paint.

The IHM has the following parts:

  • PART I: Materials contained in ship structure or equipment
  • PART II: Operationally generated wastes, and
  • PART III: Stores

The IHM Part I shall be prepared and certified for new ships and ships in operation and shall be maintained and kept up to date during the operational life of the ship, while the IHM Part II & III are only required to be prepared when the ship is decided to be sent for recycling. For the preparation of IHM Part I, hazardous materials set out in appendix 1 and 2 of the HKC or Annex I and II of the EU SRR shall be investigated.
The picture below shows part I, part II and part III.

IHM Part I for new ships should be developed at the design and construction stage based on suppliers’ declarations on the hazardous material content of the products. The determination of hazardous materials present on board existing ships should, as far as practicable, be conducted as prescribed for new ships. Alternatively, in the case where documentation is not available, samples shall be taken from the ships to investigate the hazardous materials.
For new ships, all the hazardous materials listed in Appendix 1 & 2 or Annex I & II shall be investigated, while for ships in operation Appendix 1 / Annex I is a must, and Appendix 2 / Annex II is to be investigated as far as practicable.

There are two main legislations with respect to ship recycling in the market, one is IMO Hong Kong Convention (HKC) SR/CONF/45 and the other one is the EU Ship Recycling Regulation (EU SRR) EC No 1257/2013. HKC has in total of 6 guidelines and MEPC.269(68) is the guidelines for the development of the inventory of hazardous materials (IHM) under IMO.

The Hong Kong Convention:

It will enter into force 24 months after the date on which the following conditions are met:

  1. Signed by at least 15 states;
  2. The combined merchant fleets of the signatory states are not less than 40% of the GT of the world’s merchant shipping,
  3. The combined maximum annual ship recycling volume of the signatory states, during the preceding 10 years, is not less than 3% of the GT of the combined merchant shipping of the same states.

The entry into force conditions of HKC is not met yet (Aug 2020) and its compliance is on a voluntary basis.
HKC will apply to ships, operating in the marine environment, which is equal to or above 500 GT. Navy ships and domestic ships are excluded from the scope.

According to the EU Ship Recycling Regulations:

  1. New ships flying a flag of an EU member state, shall be delivered with a valid IHM which is certified;
  2. End-of-life ships going for recycling shall have a valid IHM certified and shall be sent to one of the recycling facilities in the EU List of approved ship recycling facilities.
  3. Existing ships flying the flag of an EU member state and third-party ships visiting EU ports and anchorages, from 31 December 2020, shall have a valid IHM on-board, which is certified.

“New ship” means a ship for which either:

  • the building contract is placed on or after the date of application of this Regulation;
  • in the absence of a building contract, the keel is laid or the ship is at a similar stage of construction six months after the date of application of this Regulation or thereafter; or
  • the delivery takes place thirty months after the date of application of this Regulation or thereafter.

Cargohold Condition Survey with Virtual Reality

Posted Leave a commentPosted in 24marine, Drones, Insurance, Panama Canal, ROV, safety, smartsurvey

Every vessel or offshore installation, no matter the size and type, has a high potential accident opportunity. While the seaman, surveyors, contractors may be experts in one area, they may not be fully aware of the dangers and potential accidents that can happen onboard.

We in 24marine strongly believe that virtual reality can contribute to decrease the number of preventable accidents and bring a new dimension of details on the survey reporting systems. It has the potential to document conditions, detect failures, perform tests, and save lives in the long-term.

In the video below 24marine team conducted a Virtual Reality Survey on a Cargo Hold, using Enterprise Level Drones and Virtual Reality post-processing referring the spaces to the vessel drawings.  To navigate virtually inside the cargo hold, please click on this link http://www.24marine.com/vrcargohold/

Cargohold inspection with Virtual Reality by 24marine.com

The virtual replication of the surveys spaces allows decision makers to assess the survey areas, in details and without risking any life, a part of introducing big savings on scaffolding, equipment and preparation time. Below a summary of benefits of using virtual reality in cargo hold and confined spaces onboard ships:

  1. Increase quality.
    Virtual reality offers a common spatial experience that leads to better decision-making. Because there are almost no misinterpretations.
  2. Save time and money.
    By allowing a better pre-planning stage, as drones and virtual reality crew and sets are reduced compared with other techniques as scaffolding, ropes crews, cherry-pickers.
  3. Improve survey review.
    The inspected area gets recorded in real time (real life), can be analyzed and re-analyzed as many times as required.
  4. Reduce downtime.
    Surveys performed by drones and Virtual Reality, reduced the impact of surveys times on vessels busy and tied schedules.
