Lifting and Rigging Seminar

The 12th Lifting and Rigging Seminar took place in Amsterdam, which was organised by the International Marine Contractors Association (IMCA). It brought together many industry professionals from Europe, South Africa, and North and South America. The international conference focused on the technical and operational challenges posed by increasingly heavier lifts in the offshore wind sector. Allen Leatt, IMCA’s Chief Executive Officer inaugurated the 12th Lifting and Rigging Seminar and said that the focus for this year’s seminar is on lifting technology in the offshore wind sector.

Event update from the Chairperson of LRMC

Laura Lombardi, Managing Director, Usha Martin Italia and Chairperson of IMCA’s Lifting & Rigging Management Committee (LRMC) shares her thoughts on the recent Lifting & Rigging Seminar, held in Amsterdam.

About Laura Lombardi

Laura Lombardi is the Managing Director of Usha Martin Italia, which is the technical and R&D center of Usha Martin Group, a global manufacturer of high-performance wire ropes. Laura has a Bachelor’s degree in Mechanical Engineering and has been involved with IMCA since 2010. She became the vice chairperson of LRMC in 2016 and chairperson in February 2021.

Background of the International Seminar

The Lifting & Rigging Seminar is put together by a workgroup, comprising people involved in the LRMC’s work. Hence, they are all IMCA members with vast experience and in-depth knowledge of offshore lifting activities within our industry. The LRMC generates these events as forums for discussion between members and non-members alike with a focus on critical technical and operational topics. Bringing together a mixture of presentations and workshops allows attendees to focus on specific topics during the day, identifying the actual state of the industry and its future requirements and encouraging contractors, suppliers, and representatives from regulatory bodies to share their experiences and needs.

In this conference, Laura stepped at the last minute to Chair the seminar on the day as unfortunately David Cannell from TechnipFMC, who has traditionally fronted this event, was unable to attend. Our thanks go to David for his great contribution to getting in touch with the speakers and developing the event and we look forward to his return at the next seminar.

The theme focused on the technical side of offshore lifting and the challenges created in the renewable energy market, which is stretching the vessels and equipment capabilities, with components that are continuously getting bigger and more complex. We had a great speaker lineup with contributions from all areas of the industry, and I would like to thank each of them for their time and efforts in being part of this event and sincerely thank all attendees for their interaction.

We also had a dedicated open panel with the suppliers, in which questions and answers were shared and good discussions were initiated.

Laura said: this seminar was part of a series of events that commenced in 2012 and focused on high-value offshore wire ropes. The seminars have proven to be a great platform for the subsea contractors to discuss their issues and concerns with various equipment suppliers to come up with effective solutions for the future. Over the years, we had great discussions and have seen significant changes in the approach taken to the care and maintenance of high-value steel wire ropes within the industry. In 2018, we took the decision to return to offshore cranes. The workshops during the 2018 seminar were used to identify the industry needs and crucial topics related to offshore cranes. From this, we identified the training needs of personnel, offshore lift planning, digitalisation of offshore cranes, and general crane technology requirements. In 2019, we covered training & personnel competencies. In 2020, we were hit by COVID. However, IMCA still ran a webinar that covered Crane Systems and Offshore Lifting.

A review of some of IMCA’s key lifting documents was presented in this recent seminar, which included guidance on the selection of wire ropes, storage, transport, maintenance, discard criteria, and factors causing wire rope deterioration. This document also included the use of non-destructive examination (NDE) by means of MRT for wire ropes, to assist with inspection and integrity management.

Looking ahead

Laura reminded everyone that the next IMCA Lifting and Rigging Seminar would take place on 26th October 2023 in Amsterdam and hoped to see everyone again.

You can register yourself and sponsorship opportunities are available. Detailed information can be viewed on IMCA Lifting & Rigging Seminar 2023 – IMCA (imca-int.com).

Challenges and Opportunities in Offshore Wind Lifting Technology: A Recap of the 12th Lifting and Rigging Seminar

crane wire rope

Usha Martin’s specially designed high-performance wire ropes are one of the most crucial components in heavy-duty cranes, without which the cranes can’t function at all. Our wire rope ensures a longer operational life and minimises downtime costs. Proper storage, installation, maintenance, lubrication, and discard of wire rope needs to be carried out as per international standard ISO 4309 to extract the maximum life from our products. 

Proper Storage of wire ropes


  • Ropes should be stored in a cool, dry building and should not be allowed to be in contact with the floor. They should not be stored where they are likely to be affected by chemicals, chemical fumes, steam, or other corrosive agents. Ropes should be covered so that moisture cannot induce corrosion in ropes.
  • Ropes in storage shall be checked periodically for any signs of deterioration such as surface corrosion and, if deemed necessary by a competent person, dressed with a suitable preservative or lubricant which is compatible with the rope manufacturing lubricant.
  • In warm environments, the reel shall be periodically rotated one half-turn to prevent drainage of lubricant from the rope.

Wire rope lubrication

A wire rope is a piece of machinery with many moving parts (wires-strands) and as such it is subjected to internal and external friction causing wear and corrosion.

Suitable lubricants are applied during the manufacturing of the core, the strands, and finally the finished ropes. The service lubricant should be compatible with the original lubricant used by the wire rope company.

A good lubricant must have the following properties:

  • Good adherence
  • Resistance to penetration of water and other corrosive elements
  • Antioxidants - to resist ageing
  • Alkaline-based emulsifiers - to neutralize acid

Rope lubrication during manufacturing:

  • Petroleum base lubricant
  • Bitumen base lubricant

Basic discard criteria of wire ropes

  • Evidence of plastic wear or surface embrittlement on outer wires
  • Sudden reduction in diameter with increased lay length
  • Severe corrosion like chain pitting or internal corrosion
  • Distortions like kinking, crushing, birdcaging, etc.
  • Evidence of core-collapse or damage through heat
  • Severe shock load or overload due to some accident with equipment
  • End fitting/attachment damaged, cracked, deformed, or worn-out

Broken wires

  • Crane ropes must be considered for discard if the number of visible broken wires equals or exceeds the allowable limit.
  • Wire breaks in the strand valley indicate internal rope deterioration and require closer inspection of the rope. It should be considered for discard if there are two or more such breaks in a length of rope equal to 6 x d.
  • Broken wires adjacent to the termination, require the termination to be remade by shortening the rope, otherwise, the rope should be discarded.
  • Complete fracture of one strand or collapse of core requires immediate discard of wire rope.

Increase in rope diameter: This characteristic is often related to a change in the condition of the core, such as a fibre core swelling up due to the absorption of moisture or the accumulation of corrosion debris within the rope.


If the rope diameter increases by 5 % or more in a rope with a steel core or 10 % or more in a rope with fibre core during service, the reason for this shall be investigated and consideration is given to discarding the rope.

Decrease in rope diameter: A decrease in rope diameter can result from a number of factors, one of which is external wear. Usually results from contact with sheaves or drums or from the pressure of rope on the rope, as would be expected at the cross-over zones as the rope traverses the drum. More pronounced amounts of wear are usually found in those sections of rope which are in contact with the grooves of sheaves and drums when the load is being accelerated or decelerated. A lack of lubrication and the presence of abrasive dust can also affect the rate of wear. In addition to the obvious visible mode of deterioration described above, the rope can also decrease as a result of one or a number of internal mechanisms, such as:

  • Internal wear is caused by friction between adjacent strands and wires in the rope, particularly when it is subjected to bending.
  • Deterioration of a fibre core or fracture of a steel core.
  • Fracture of the inner layers of strands of a rotation-resistant rope. By reducing the metallic cross-sectional area of the rope by wear, the strength of the rope is reduced.

Conclusion: We at Usha Martin are committed to working together with our customers to extract the optimum life cycle from our wire ropes. Therefore, proper storage, handling & installation of wire rope is crucial. Thus, being one of the leading wire rope manufacturers, we follow international standards as per ISO 4309 in helping our end-users to achieve maximum performance from our products.

In this blog, let us discuss the application of wire ropes used in Ports and Mines.


wire rope ports 

As transportation of goods by sea is more economical than either air or land, hence worldwide logistics through ships play a major role in the smooth functioning of business by carrying a huge volume of goods and materials from one country to another. Here ports play a major role, where goods are unloaded in the form of containerized loads or bulk material from the ships.

Unloading the goods from vessels within a limited timeframe is one of the biggest challenges faced by port terminals. Very high-capacity cranes are deployed in both container terminals and bulk material handling terminals to carry out these enormous tasks, which operate at a level of 50-60 meters above the ground. Here, the quality and life cycle of the wire ropes installed on heavy-duty cranes are crucial as they affect the downtime cost.

Usha Martin’s specially designed high-quality wire ropes are one of the most crucial components used in these heavy-duty cranes, without which the cranes can’t function at all.

A few key factors for preferring the Usha Martin brand are:

  • Accident-free performance ensures maximum human safety.
  • Longer service life.
  • Reduced downtime cost/ frequency to achieve the committed time cycle of port clearance.
  • Repeated contracts with major global port operators.

Over the years, we have developed a wide range of high-performance wire ropes, including plastic-impregnated compacted ropes with special properties that have delivered excellent results for our customers and helped to enhance operational efficiency in ports.

When it comes to optical fiber cable manufacturers, “Usha Martin” is one of the most popular brands in the market as they are equipped with global standard manufacturing units to produce high-quality optical fiber cables. Usha Martin is one of the world’s leading cable suppliers.

Fiber optic cable is suitable for the transfer of information using the medium of light. These cables consist of thin, transparent glass fiber rods. The fibers have three layers; the first layer is called the core, which is comparatively very smaller in diameter than the average hair diameter. Cladding is the second layer, which is constructed with a different refractive index as compared to the fiber core. Cladded fiber forms the third layer, i.e., acrylate coating. These fibers are cascaded in polymeric tubes. The multiple tubes are wrapped around to strengthen the members. The complete unit is coated/encapsulated in a sheathed/jacketed compound.

Types of Optical Fiber:

1. Single-Mode Fiber: Single-mode fiber optic cables are used for long-distance signal transmission.

2. Multimode Fiber: Multi-mode fiber optic cables are manufactured with a wide diameter and larger cores. These cables are used for shorter data transmissions.

Types of Optical Fiber Cable

There are generally four types of optical fiber cables. The following cables are different as per their build type and usage:

1. CATV Cable: Used for cable antenna TV signal transmission.

2. Multi-Loose Tube OFC: These cables are manufactured with multiple tubes for branch communication.

3. Armoured OFC: Armoured cable is used for direct burial or trench deployment applications.

4. ADSS OFC: All Dielectric Self-Supporting Optical Fiber Cable is used for hanging applications, exhibiting very strong pulling strength.

The Benefits of Optical Fiber Cable

Fiber optic cable has many benefits, and a few of them are explained below:

1. Bandwidth & data transfer: Fiber optic cables are the best for data transfer and efficient transmission of signals.

2. High Speed: These cables use light pulses for data transfer and provide a higher speed of transmission.

3. Distance: Fiber optic cable can cover a very long distance as compared to copper cables. These cables offer less optical or transmission loss in signals.

4. Interference: Fiber optic cables offer high protection against interference compared to traditional metal wires. It has the capability to boost data transfer for much longer distances with safety.

Everything You Need to Know About Optical Fiber Cable

There is no denying that wire ropes are one of the most used materials in the industrial landscape. According to Statista, in 2020 itself, the production volume of steel wire ropes in Japan amounted to approximately 240.32 thousand tons. Their necessity is evident, and the wire rope sling manufacturers are increasingly deploying their solutions in marine environments or for rigging purposes. However, as wire ropes face considerable loads, they suffer massive mechanical damage.

As suggested by the leading steel wire rope manufacturers, some well-known reasons for wire rope failure are corrosion, excess deterioration, improper usage, and lack of maintenance resulting in reduced safety, increased replacement costs, and early discard. Do you want to know the professional ways steel wire rope manufacturers inspect wire ropes? Then here's a guide for you!

How often should you inspect your wire ropes?

All wire ropes must be inspected visually on daily basis before starting the operation. This safety guideline can ensure maximum security. Although it's daunting to determine the exact service span of the ropes, close analysis on a more frequent basis can help get a more precise estimation of their predictive life cycle. Also, note that calculating the precise times when the ropes have been in use during the mooring/tidal conditions, load pressures, etc., can be the answer. A competent person shall carry out an overall, thorough periodical inspection of the wire rope.

How to inspect a wire rope visually?

Well, you can assess the wire rope condition by standard inspection. Look for signs of:

  • Wire Breaks (Pro tip: valley wire breaks are more hazardous than outer wire breaks)
  • Abrasive damage that is caused by passing over the drum and sheaves during daily use
  • Corrosion is caused by the lack of lubrication. (Pro tip: look for discoloration)
  • Diameter reduction due to excessive abrasion under normal load conditions
  • Crushing or flattening of wire rope strands
  • High Stranding
  • Shock-loading or bird-caging-caused by the abrupt release of tension on the wire rope leading to overloading

The rag and visual method

You can use the rag-and-visual process to check for any external damage. All you need to do is grab the rope lightly with a rag or cotton cloth. Then move the rag along the wire, and if there are any broken wires, they will stick out and snag on the rag. If the cloth catches broken wires, you can stop and assess the rope visually. Also, make sure to visually inspect the wire without any rag because some wire breaks don't stick out.

Measure the rope diameter vividly

Measure the diameter of the rope and compare the diameter with the original values. When the measurements are different, the change implies internal or external rope conditions.

Check for abrasions

When a steel wire rope passes over the drum and sheaves or any other metallic equipment component, abrasion takes place. Hence, it is important that all components must be in proper working order and of the appropriate diameter for the rope. A badly corrugated or worn-out sheave or drum will significantly damage a new rope, resulting in premature rope replacement.

In addition, try to look for corrosion, pitting, abrasions, end fitting conditions, wire breakage (if any), and lubrication inside the rope. Wire rope should be inspected to check for any abnormality like External damage, Kink, Strand looseness, Core protrusion, or Bird-caging.

It is always recommended to maintain the inspection records to assess the rope condition in the next inspection schedule.

Word of caution

While sometimes the damage can be easily identified on the surface, in other cases, the fracture might occur inside the wires. Therefore, ensure that the ropes are maintained, manufactured, and inspected by competent professionals.

Offshore wire ropes, slings, and other rigging equipment handle heavy loads in daily operation. In addition, they are constantly exposed to adverse weather conditions, saline ocean water, etc. Like any machinery and equipment, wire ropes and slings also need proper care and maintenance to ensure their longevity and strength.

That's why we are discussing 5 Care and Safety Tips for Offshore Wire Ropes.

1. Seizing wire ropes

Seizing or cutting wire ropes is vital to deploy them in suitable applications. Moreover, seizing them appropriately is a must to ensure safe and efficient operations. Improper or inadequate seized ends of ropes can be colossal trouble ahead since it can cause flattening of ropes and uneven distribution of load, making it susceptible to premature wear and tear.

2. Routine inspection and cleaning

Since wire ropes are primarily used for heavy equipment lifting, you must conduct regular inspections. Any carelessness or lack of maintenance can cause the ropes to break, resulting in huge losses, accidents, and even fatal injuries. If any change or issue in the rope is noticed during inspection, it must be immediately reported.

3. Ambient lubrication

Although most wire ropes come with original lubrication, it often gets removed due to constant friction and adverse conditions. The wire rope is constantly exposed to environmental elements if the lubrication isn't replenished. Thus, it is advised to maintain proper lubrication to protect the wires and the core from dust, debris, unwanted friction, and corrosion.

4. Professional installation

Are you installing offshore wire ropes on your own? You better leave it to professionals unless you have the proper training. Professional wire rope installers are well-trained in considering every little detail during installation. For example, they use suitable tools like calipers to calculate the rope's nominal diameter to see if it is compatible with the equipment.

5. Proper storage

If you are storing the wire ropes, ensure they are in dry, covered, and well-ventilated conditions. The best practices are keeping them away from moisture, dust, steam, chemicals, and adverse weather conditions.

High-Quality Offshore Wire Ropes: Care and Safety Tips

Steel Wire


International prices of base metals have gradually slashed from 9 to 17% since April from the soared levels, giving some relief to the related industries, which noticed a sharp rise in input prices. Between April 11 and May 10, a sharp fall of 15%, 9%, and 17% was noticed in the LME, copper, and zinc prices, respectively. China's domestic price of HRC (hot-rolled coil) steel fell by 15%.

As per Trading economics, steel prices have dropped below CNY 4,500 per tonne, a level not seen since last December. They are now roughly 15% below their early May peak due to persistently weak demand and rising inventories.

Some glimpses from the past

In 2021, the steel price in the Indian city of Chennai reached 59.78 Indian rupees per kilogram. On the other hand, steel in Pune was less expensive at 58.08 rupees per kilogram. Therefore, it was projected that steel prices would decrease in all the presented cities. However, driving demand for Indian iron ore in China is said to have increased the steel price in India significantly at the end of 2020.

In India, the steel price varies depending on the cost of import and the prices of other metals and raw materials. Because of these underlying causes, steel prices crashed to ₹65000 per ton from a whopping ₹71000 per ton. Prices were seen at ₹76000 per ton in April 2022, but because of the excess supply during the weak demand, the prices fell with the incoming southwest monsoon slowing the work.

According to analysts, the market expects steel prices to go to ₹60,000 per ton in July 2022 and drop to ₹55000 per ton in August 2022. However, it may not fall further and then gain stability.

Currently, the steel market is in a chaotic condition, and demand is stagnant because of the undercutting done by dealers in expectation of the price reduction by steel manufacturers. Steel price fell by ₹5000 per ton because of the imposition of export duty, and the hot-rolled coil presently hovers at ₹65000 per ton.


Major industries affected by the fall in steel prices

A lot of manufacturing units rely on steel for their products and services. From automobile manufacturers to consumer electronics, 'steel' enjoys a huge presence. It is also used for equipment, machinery, steel wire ropes, and hardware production.

The major industries impacted by the fall in steel prices are:

  • Energy
  • Automobile
  • Appliances
  • Construction
  • Steel wire rope
  • Machinery
  • Engineering


Here are the reasons why steel prices crashed

Government steps: A rise in export duty

To control roaring steel prices, in May 2022, the government hiked the export duty on finished steel to 15%. However, the government did not include steel intermediaries in the export duties list.

Post this, the semis exports declined by 26% last year to 4.9 MT. However, they may notice a rise in the current financial year. The demand for domestic steel fell by 7.2% every month and is expected to fall more. The fall in the raw material cost will have a positive impact on the manufacturing sector and also help to keep the prices in control. In addition, the fall in import duties of iron ore and steel will enhance domestic availability and further help reduce steel product costs.


China's steel demand

As per Fitch experts (an American credit rating agency), the steel demand growth from the construction industries of China has largely peaked in the first six months of 2021. The firm never estimated any demand effect from government incentives after the pandemic struck in April 2020 to support the post-Covid recovery. With current projects and new infrastructural work being taken up, the steel demand will rise during 2022-2025; the company doesn't predict the gush in demand to return from 2022 onwards.

Most Common Wire Rope Terminology

Does your business largely depend on wire ropes? The steel ropes used in heavy-duty applications are specially designed with the required specifications to meet the requirements of the most demanding applications. A typical wire rope is made of four components—wire, strand, core, and rope. Apart from these, you might come across many other terms while dealing with wire ropes in day-to-day industrial activities. Read further to learn about some of the most common wire rope terminologies.

Common Wire Rope Terminology:

  • Wire- The individual strands that make up the wire rope.
  • Strand- A group of wires bound together to make a rope.
  • Core- The centre of a wire rope is often made of steel, sisal, jute, hemp, etc.
  • Rope- The final product comprises several strands wrapped around the core.
  • Bending Stress- It refers to the amount of stress laid on the wire when bent.
  • Abrasion- Day-to-day surface wear and tear on the wire ropes.
  • Aircraft Cables- These are specially crafted wire ropes designed to handle aircraft operations and related uses.
  • Construction- It refers to the building of the wire ropes, which includes the number of wires per strand.
  • Metallic Area– The total cross-sectional area of all the wires within a strand or rope.
  • Corrosion- Chemical damage to the metal wire ropes due to exposure to moisture, acid, alkaline, sea salt, and harsh cleaning agents.
  • Corrugated- When the surface of a reel or drum shows worn-out streaks due to wire ropes rubbing against it.
  • Drum- A large cylindrical barrel around which the wire rope is wrapped for storage purposes.
  • Elastic Limit- The maximum limit until a permanent deformation occurs in the ropes.
  • Fatigue Resistance- The wire ropes' resistance capacity lets them repeatedly bend without breaking.
  • Fiber Core– When the core of the wire rope is made of natural or synthetic fibre like sisal, vegetable material, polypropylene, etc.
  • Grooves- Indentations on the periphery of the drum or sheave that are shaped to position and stabilise the wire ropes in one place.
  • Grooved Drum– A drum with grooves that help easy support and winding of the wire roped around it.
  • Kink– A noticeable bend in the wire rope which is caused by the loop being pulled through. This bend permanently distorts the wires and strands of the rope.
  • Lay– The pattern or length along the wire rope that a strand takes to wrap completely around the core.
  • Left lay– In the case of strands, it refers to those wire strands that are braided into a helix having a left-hand pitch. Similarly, in the case of ropes, it relates to a rope where the helix pattern is formed with a left-hand pitch.
  • Reel– A spool around which the wire rope is wrapped like a roll, especially during storage and transportation.
  • Rotation-Resistant Rope– A rope having two layers of strands where each of the layers has opposite lay directions, allowing smooth rotatory movement.
  • Slings– Wire ropes that are fitted with other operating ropes for lifting heavy loads.
  • Socket– Socket means the type of rope fitting. It can be of three types: open, closed, and wedged.
  • Thimble– It is a single metal fitting with grooves, often used to cover the eye of a wire rope.
  • Breaking Strength– The tensile load at which the wire rope breaks or the tensile failure occurs.
  • Aggregate Strength- The sum of the individual strengths of each wire when subjected to tension.
  • Nominal Strength- Steel wire manufacturers in India use this standard of minimum strength calculated for wire ropes while designing.
