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 ( 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.

WHAT IS IHM (Inventory of Hazardous Material)?

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

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

Cargohold inspection with Virtual Reality by

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.

Llegarán más de 80 cruceros a Colón

Llegarán más de 80 cruceros a Colón

Alma Solís

Alrededor de 80 cruceros llegaran a la ciudad Atlántica de Colón en Panamá desde septiembre hasta diciembre así lo dio a conocer la empresa que maneja el Puerto de Cruceros Colón 2000, calculando un derrame económico para el país de alrededor de US$25 millones.

La temporada de cruceros regular   comenzará   en el mes de septiembre y se intensifican   la llegada de cruceros en los meses de octubre, noviembre y diciembre.

Se calcula que aproximadamente 200,000 turistas bajen a conocer los atractivos turísticos cercanos al puerto caribeño y si se toman en cuenta los cálculos de la Autoridad de Turismo Panamá que   maneja cifras de la FCCA, la Asociación de Cruceros de Florida y el Caribe, que indica que cada pasajero que baja a puertos   gasta     US$125.00 el resultado es un derrame económico al país US$25 millones.

Los cruceristas realizan giras que comercializan las operadoras   panameñas están las visitas a   las esclusas de Gatún y las de Agua Clara en el lado Atlántico del canal. Además de hacer compras en centros comerciales de la ciudad de Panamá, Zona Libre y   giras ecoturísticas.

De acuerdo con Colón 2000, el   crucero estrella de este puerto de cruceros sigue siendo el Monarch de Pullmantur que   programa por lo menos   16 salidas desde el puerto colonense. Sale todos los viernes.

El calendario de finales del año 2018 está adornado con llegadas de cruceros como el Infinity de Celebrity Cruises, el Island Princessm, el Norwegian Pearl que traen además cruceristas norteamericanos,   ingleses, y alemanes. En el mes de noviembre se esperan 31 cruceros y otros   30 cruceros en diciembre.
