Safety and quality effortlessly combined

HTL Group Logo - Circle

Incorrect measurements and tool inaccuracies in all industrial sectors can lead to hazardous consequences not least of all risk to personnel safety. So ensure operator safety and minimise downtime with HTL Worldwide’s range of Torque Calibration rigs.

A common misunderstanding is that only used tooling must be calibrated, when in actual fact calibration should also be carried out on new tooling to ensure accuracy is maintained from the beginning of use.

HTL, a Global OEM of controlled bolting equipment, recognises the critical importance of tool calibration, and have therefore designed highly safe, premium quality torque calibration rigs to allow clients to entirely control their own in-house calibration.

Mike Johnson, Group Director of Engineering, HTL Group comments:

The reality of accurate calibration is that it’s a necessity for industry but it mustn’t come at the expense of project downtime. The new range of torque calibration rigs bring to market a fully integrated piece of equipment incorporating unique safety features. The ability to calibrate tools to a planned schedule effectively contributes to reducing downtime, allowing client projects to run as planned.”

Technically suited to any industry or business who frequently calibrate torque tools, the HTL range of torque calibration rigs enhance the existing market offering by introducing a standardised range of quality torque calibration rigs, with the ability to customise to meet every individual requirement.

As part of the Premier range, the enclosure incorporates Norbar torque measurement equipment, an interlocked safety canopy, a heavy duty and robust modular frame, lockable pump cupboard and safety interlocks to ensure operator well-being during use. The Premier Rig also includes an integrated control panel, electric pump, a precision gauge and an emergency stop mechanism to further promote safe operation.

RUD ICE Chain Pink Powder Coating acts as overheating indicator

RUD Logo

Ideal for Offshore Polar & Arctic Projects:

RUD ICE chain offers extreme resistance to temperatures from -60°c to +300°c which makes it the perfect choice for my offshore polar and arctic projects.

The ICE chain is coated with RUD’s innovative pink powder coating which acts as an overheating indicator. It shows the temperatures in which the chain can be safely used.

The chain cannot be used in temperatures above 300°c. If the chain reaches temperatures of 300°c or above it will turn from a pink colour to brown, then black which indicates that the chain is unsafe to use and must be taken out of service. The pink powder coating therefore offers a unique safety factor highlighting when the chain is no longer safe for use.

The advantages of RUD ICE chain are abundant. It offers a considerable 30% reduction in weight than Grade 80 chain, using less material and energy used due to its light construction & easier handling. It possesses a 60% higher breaking force than grade 80 chains, is extremely robust, tough and resilient to sharp and rough edges due to the chains increased strength.

Operating in hot or cold environments from -60°c to +300°c ICE Chain offers the solution to your lifting requirements. From offshore, arctic projects to extreme materials handling at ports or construction sites where sharp and rough edges are present, RUD’s ICE Chain offers ultimate strength and resilience to varied environments.

Petrochemical plants made in Italy that makes production safe and reliable


As one of the most precious natural resources, petroleum contains crude oil and other useful components, and we convert it into different types of fuel or products through petrochemical plants and oil refineries. A Fractionating Column is definitely indispensable in this process.

Crude oil will be heated at very high temperature and sent to the base of a fractionating column, after eliminating the salt in the oil to avoid corrosion to the petrochemical plant. When crude oil moves upwards, it will be separated into diesel, kerosene and naphtha, thanks to their different molecular weight and boiling point. Of course, these oil derivatives should be refined through more distillations to make it more pure and effective.


This type of distillation is composed of different phases, and takes place inside a single column, which has a complex structure with different entry and exit points to allow the crude oil to be reinserted for a better efficiency of the process. It is a delicate work and requires the precision in the processing and excellent quality of the plant. Here it worth mentioning that Cividac, an Italian company with over thirty years’ experience, deeply studied in this field and produce metallic equipment especially for petrochemical industry in both national and international market. Their specialized management and trained operators guarantee a proper processing, eliminating errors that can compromise the quality of the product.


Besides the columns, Cividac also produces Pressure Vessels, Heat Exchangers, and so on, designed for complex industrial proposes. And the company uses all types of stainless steels and alloys to achieve the goal of quality and safety. One of the most relevant advantages of using stainless steel is its corrosion resistance, combined with safety and convenience. Thanks to the presence of alloying elements such as chromium or nickel, stainless steel become particularly resistant to corrosive attack of the atmosphere, water and many solutions of acids, salts and alkalis. And it is widely used today in the petrochemical and chemical industries, especially the type of austenitic steels with chromium, nickel and molybdenum.

Marex Supports Clients with Industry Legislative Compliance Verification Schemes and SECEs – SCR15



Safety is a top priority in the oil and gas industry. Marex employs a team of highly qualified Risk and Safety Engineers, Master Mariners, Marine Engineers and Naval Architects to oversee the delivery of a professional, consultative and cost effective solution to the offshore industry’s marine and safety needs.

In 2015 the EU directive on Safety of Offshore Oil and Gas Operations introduced changes to UK Safety Case regulation, resulting in the implementation of the Offshore Installations (Offshore Safety Directive) (Safety Case etc.) Regulations 2015 (SCR15). These regulations apply to all installations engaged in oil and gas operations in territorial sea adjacent to Great Britain and any designated area within the United Kingdom Continental Shelf. The regulations aim to reduce, as far as possible, the occurrence of major accidents relating to offshore oil and gas operations and to limit their consequences. One of the major changes from the previous regulations was the requirement to consider the potential environmental impact of a major accident.

Since the implementation of SCR15, Marex has completed over 10 safety cases for major drilling contractors in the industry and conducted thorough reviews of safety cases for some of the biggest names in oil and gas. This puts Marex’s highly skilled team members in an excellent position to assist companies with the revision of safety cases for SCR15.

One of the key requirements of SCR15 is that each offshore installation should establish a verification scheme to ensure that the installation’s Safety and Environmental Critical Elements (SECEs) remain in good repair and condition.

SECEs are defined as those parts of an installation or of its plant, the failure of which could cause or contribute substantially to a major accident, or the purpose of which is to prevent or limit the effect of a major accident.

Verification Schemes

The verification scheme is a statement of the suitability of the record of safety and environmentally critical elements and the scheme of maintenance.

The verification scheme establishes a system which ensures efficient operation of the installation through the continual review of the SECEs. Each SECE has an associated performance standard, which demonstrates their suitability, state of repair and condition based on function, reliability and availability.

For non-production installations, a verification scheme must be in place before commencement of any oil and gas operations in UK offshore waters.

The verification scheme is a live document, which must be reviewed and updated as often as appropriate and the provisions for such should be outlined within the document. As a minimum the following should be considered during the review of the verification scheme:

  • Any development which could alter the SECEs
  • Anything which affects the verification arrangements appropriate to them
  • Matters which change the nature or frequency of verification activities

This review could potentially lead to a revision or replacement of the verification scheme.

Any changes to the operation of the installation that may change the requirements of the SECEs will result in a revision of the verification scheme and the associated performance standards, for example the conversion of an installation from non-production to production.

By ensuring the SECEs meet their required performance standards the duty holder provides some assurance that the SECEs are suitable and remain in good repair and so minimise the likelihood and potential consequences of a major accident.

A performance standard is developed for each SECE and included within the verification scheme. The performance standard states the required performance of the system described in terms of functionality, reliability, availability and survivability, against which the suitability and condition of the equipment can be assessed.

It is required by SCR15 that a description of the verification scheme is provided within the installation’s safety case, including the following details:

  • Examination and testing of SECEs by independent and competent verifiers
  • Verification of design, standard, certification or other system of conformity of SECEs
  • Examination of work in progress
  • Reporting of any instances of non-compliance

Identification of SECEs

The safety and environmentally critical elements for the installation must be identified before an effective verification scheme can be developed.

It is necessary to undertake a systematic approach to identify those systems which are SECEs. Within these systems many of the individual components may by SECEs, but others may not. SECEs include those systems for detection, control and mitigation of major accidents along with those systems which increase reliability through redundancy. This list of SECEs will vary depending on the installation’s design and operations. There may also be SECEs introduced for limited activities such as combined operations.

For example the BOP on an offshore drilling unit would be considered a SECE and a performance standard for it would be included in the verification scheme.

The starting point for the exercise to identify SECEs would be the identification and qualitative risk assessment of the major accident hazards associated with the installation operations. The risk assessment should identify the threats and potential consequences associated with each major accident hazard, as well are the measures which are in place to prevent occurrence of the major accident and to mitigate the potential consequences.

Bowtie Workshops

In order to help our clients demonstrate compliance with the safety case regulations and to show that the major accident hazards associated with the operation of the installation have been subject to appropriate risk assessment, Marex facilitates bowtie workshops which are designed to enable the identified major accident hazards to be qualitatively risk assessed by relevant stakeholders, including the rig crew. In order to do this BowtieXP software is used. When running workshops to align with the new requirements of SCR15 one of the main aims is to identify the equipment barriers associated with the control of major accident hazards, including those which could have a major environmental impact. It is therefore important to qualitatively assess the environmental risk associated with each major accident hazard, as well as ensuring that sufficient barriers are in place such that all risks associated with identified major accident hazards continue to be as low as reasonably practicable (ALARP).

Each scenario is represented by its own bowtie, such as the one below.

Marex graph.1.1


A bowtie diagram presents the hazards and their controls in a logical and structured manner. It can serve several purposes, e.g. as a methodology for identifying barrier functions and elements related to present hazards as well as communicating risks and control mechanisms efficiently.

Any structure, plant, equipment, system or component part whose failure could cause or contribute to a major accident is a safety and environmentally critical element, as is any which is intended to prevent or limit the effect of a major accident. The bowtie diagram is made up of the following components:

  • Hazard – an intrinsic property of anything with the potential to cause harm
  • Top-event – initial consequence that occurs immediately after the hazard is released
  • Threat – potential to cause the top event
  • Consequence – event or chain of events that results from the release of a hazard
  • Barrier – measure that reduces the probability of releasing a hazard
  • Escalation factor – condition that can cause a barrier to fail

The barriers can be classed as people, plant or process barriers. With regards to the verification scheme, the most important of these are the plant barriers as they will help us to identify SECEs. Details of the personnel responsible for the operation and/or maintenance of the barriers are also included. A typical plant barrier is shown below.

marex graph 2.2

This barrier is for the BOP system and tagged on it are the two relevant SECEs (SECE 01 – BOP and SECE 02 – BOP Control System), as well as the person responsible (in this example the Subsea Engineer). Every barrier for each of the identified major accident hazard scenarios is tagged similarly to the barrier shown here with the appropriate associated SECE.


Oil and gas is a fast paced industry where low probability events with catastrophic consequences could easily be overlooked. It is important to ensure that every eventuality has been identified and assessed for all potential outcomes. The introduction of SECEs and the emphasis placed on the verification scheme and performance standards through SCR15 has helped to prevent and mitigate these major accident hazards.

Marex continues to provide a high standard of work for its clients, which in turn enables them to fully demonstrate compliance with SCR15 ensuring all aspects of workplace risk and safety have been accounted for through identifying, minimising and eliminating the risks to their employees, their assets and the environment.

Disruptive technology has a flagship.

New class of vessel to shake up decommissioning.  Topsides and jacket removed in a single lift, without breaking the bank.  This is a floating dry dock with a twist.

Using some of the same principals as their game changing semi-submersible MPSS (Multi-Purpose Semi-Submersible), Seaways Engineering International have changed Heavy lift forever.  With the Novel Extended Semi-Submersible for Installation and Decommissioning (NESSI/D).   This is an economical purpose built workhorse.

Nessie front page of two pager  3600x2880


A zero heave vessel

Nessie is a supremely capable vessel.  Envisioned as an economical (by comparison) Installation & decommissioning vessel, her abilities are evident. By lifting from below a great deal of the expensive and dangerous practices associated with heavy lift is eliminated.

Starting with our MPSS building method we designed a massive drydock with a removable center deck/submersible barge and a floating gate at one end. Then we added some “off the shelf” lifting gear to customize on the fly for any lifting situation.  Because Nessie starts as a zero heave vessel we can eliminate motion compensation, a very expensive and elusive process.  This allows us to work as if on land unlike any other vessel.  Even in severe weather, Nessie would not have to run for cover.  She could back away from the rig to a safe distance and sit at anchor to wait the storm out, saving transit time.

A floating dock with a gate at one end and a removable deck will allow NESSIE to operate as a traditional drydock but also allow the vessel to surround a rig and lift from below, much like a forklift.  This method of lifting is much safer and more efficient.  Others build a vessel to hold a crane we use the vessel as the crane.  Getting over the load has always presented problems, we eliminated the need.

The topside lift.  Nessie can surround a rig, that changes everything.  Using ballast water Nessie gets low enough to get under preinstalled structural supports she dumps ballast lifts the topsides.

The heaviest topsides weigh Between 20,000 & 30,000 tons.  What is an impossible lift for a standard crane would be easy.  Simply by draining some of her 300,000 tons of ballast in a controlled manor she will simply lift and carry that weight.

With the Jacket still low in the water, we attach lifting cables to the jacket by ROV.  The anchoring pylons are cut, we deballast and lift the jacket free of the seabed.  Our programing will control the winches in a manner that will lift then rotate the Jacket under water.  Once horizontal the jacket is secured in position between the pontoons.  The process is reversed for installation and delivery.

Although typically much lighter than the topsides, the heights of some Jackets can be difficult for a traditional crane vessel to handle.  Cranes simply don’t have the reach to lift a tall tower onto the deck of a barge.

Safety, always on everyone’s mind, is a byproduct in Nessie’s case.  Traditional cranes operate on at perceived safe margin.  Figuring in things like “acceptable risk” is all part of it.  As we all know on a crane, if anything goes wrong, everything goes wrong.  We don’t have those problems.  Our lifting capacity is far beyond any actual required lift in the North Sea.  Our topside connections are solid and over engineered.  Our Jacket “sling” is made of far more connections than needed.  So if one breaks, it is a surprise and the program compensates for the loss and nothing more.

Avoided because we can.  Motion Control systems, high volume ballast balancing systems, operating at vessel limits, they are all unsafe and they all cost a lot of money.  Nessie can lift many times the stated limit of even the largest SSCV or purpose built Decom Vessel.  She carries 300,000 ton of ballast at her low operating draft.  That translates a theoretical lift >300,000 ton.

We have a smaller version for the shallow southern North Sea.  Wee Nessie is suitable for Topside only lift or vertical lift in shallow areas where she won’t need to rotate the jacket.  Depending how tall the jacket is we can lift the entire rig topsides and all and transport to the desired location.
