NOPSEMA Safety Alert 64 “Collared Eyebolts as Lifting Equipment”

NOPSEMA, has today released a Safety Alert 64 relating to the use of collared Eyebolts as lifting equipment as a result of a failed lifting activity on a mobile offshore drilling unit (MODU).

What happened

MODU crew were replacing the diverter on a MODU facility operating in Australian waters. The new diverter had been placed on its side in a cradle on the main deck for change-out of the flex-joint. Subsequently, the diverter was lifted with the intent of rotating it from the horizontal to its working, vertical axis. When the diverter had been lifted between 1.2 to 1.8 metres above its cradle, one of the two collared eyebolts used for lifting the diverter body sheared, see Figure 1 below. This caused the diverter to rotate and the second eyebolt to become dislodged from the diverter body. The diverter then fell back into the cradle on the main deck. The combined diverter and the running tool weighed approximately 21.7 tonnes and fell a distance of 1.2 to 1.8 metres. No persons were injured in the incident.

The primary immediate causes of the incident were found to be:

  • The lifting equipment was configured such that the direction of pull was at an angle to the shaft of the eyebolt, so that a ‘fleet angle’ from the vertical was created. An angular load such as this reduces the Working Load Limit (WLL) of the eyebolt significantly. See Figure 2 below.
  • The collar of the eyebolt was not fully flush with the body of the diverter, causing a shearing force due to the fleet angle to be applied to the shaft of the eyebolt, instead of the load being spread across the eyebolt’s collar and the surface of the diverter as per design.

Lift planning was previously addressed in NOPSEMA Safety alert #59 in July 2014, which advised the industry that ‘the detail required in the lifting and rigging plans should be proportional to the complexity and frequency of the operation. Frequent or simple tasks may only require a basic plan while infrequent or complex lifting or rigging operations may require significant engineering.’

Significant business impacts to people and assets can and do occur during lifting activities. You should always ensure that all equipment is certified and rated for the activities being conducted. Individuals involved in the activity are certified competent to conduct the activity. A risk assessment has been conducted and documents which identifies if the lifting activity is simple, complex and or complicated. Ensure that a proper engineering lifting plan is provided and followed for complex and complicated lifts. Lastly ensure that all non essential personnel are excluded from the area and barriers are in place.

DMP Awards to recognise excellence in the State’s resources sector

Western Australia Department of Mines and Petroleum (DMP), have announced nominations for the 2017 Department of Mines and Petroleum Awards for Excellence are now open.

Previous years the awards for excellence has included the prestigious Golden Gecko environmental awards, Community Partnership Resources Sector Award, and for the first time, the DMP has introduced a new award category “the Safety and Health Resources Sector Awards”.

By recognising exceptional advances and innovations throughout the resources sector, the DMP seeks to encourage higher industry standards to help develop and maintain community confidence in mineral and petroleum activities.

The Safety and Health Resources Sector Awards recognise individuals, teams and companies that have developed a new initiative or an original solution to specific safety and health problems in the workplace.

The Awards aim to promote the application of safety and health innovation across the Western Australian resources sector. This may involve new initiatives and leadership which support the safety, health and wellbeing of the workforce; implementation of a new process, procedure, design and/or introduction of innovation or new equipment in response to specific safety and health challenges.

Entry is open to all Western Australian resources sector companies and/or sites including contractors.

The Community Partnership Resources Sector Award recognises outstanding achievements and leadership in building constructive community partnerships that provide positive outcomes and promote strong guiding behaviour for industry.

The award publicly recognises partnerships between resource companies and communities that extend beyond the normal obligations and requirements to leave a positive and lasting legacy.

That recognition aims to build the reputation of resources and extractive industry operators that are working closely with communities, or community groups, to understand local concerns and issues, provide constructive outcomes, and leave a positive legacy that extends well beyond gaining a social licence to operate.

The Golden Gecko Awards for Environmental Excellence recognise leading practice and innovation in environmental management and provide an opportunity to share experiences between government, industry and the community.

Since the inception of the Golden Gecko Awards, the department has presented 59 Award recipients and 51 Certificate of Merit in acknowledgment of outstanding contributions to develop WA’s resources in a responsible manner.

The awards provides an opportunity to share experiences between Government, industry and the community, while helping operators build the reputation of being a responsible corporate citizen with a responsible attitude to the environment

Details on entries and associated timeline can be found at http://www.dmp.wa.gov.au/About-Us-Careers/Awards-for-excellence-19157.aspx
