Work-at-Heights Solutions – Dredging International @ Tuas Terminal
Date of event: 15 March 2018
Dredging International (Belgium) is one of the world’s largest Marine & Dredging company, contracted to construct Singapore’s Tuas Terminal Mega Port, involving a fleet of 6 own vessels more than 20 externally chartered vessels.
United Resources were proud to be invited for the Work-at-Height Safety Assessment and involved in the below scope:
1. Design, Installation & Commissioning of Engineered Lifeline System onboard Dredger’s Crane Boom
– Crew are exposed to high level of fall hazards when doing maintenance on top of vessel crane boom, with zero fall protection structure (especially for greasing where slip hazards are increased)
– Bespoke design due to unique crane boom beam structure and penetrative fittings (i.e. bolting, welding, drilling, etc) not allowed to protect crane boom’s material integrity
– Designed and installed 2 x 40m length Horizontal Lifeline System with 10 x stud bracket clamps, together with use of Patented Transfastener™ Device to allow crew to walk through entire boom length without hassle/obstruction from intermediate support brackets
– Due to open environment without adequate anchor point for conventional rescue kit operations, Personal Rescue Device (PRD) was also implemented as post-fall Rescue Plan, which provides quick and easy self-rescue to main deck
2. Re-engineering & Modification of existing uncertified Safety Lifeline System onboard barge
– Inspection and qualification of existing bespoke safety wire lifeline
– Bespoke design found to be missing key components and design elements to qualify as safety lifeline under international standards
– Re-engineering works done using existing components, instead of replacing entire system with new lifeline, for cost-effective solution
– 2 x 25m certified safety lifeline system installed, providing necessary work-at-height protection to crew onboard
3. Inspection & Re-certification of Vertical Lifeline System onboard Drilling Rig
– 4 x Drilling Masts (40m each) fitted with existing Vertical Lifeline Systems
– Inspection done to found and effect minor rectifications, for the re-certification of lifeline system
– Unsafe, exposed fall potential areas identified and proposed solutions for rectification
– Training of project crew onboard for proper usage, pre-use checks and maintenance of lifeline system and fall protection equipment
