Range of Services in Asset Management

Crane and Scaffolding:

Crane

All cranes represent a significant safety risk. They are complex and involve significant mechanical, structural and control safety aspects. The maintenance criteria includes compliance with the requirement of Lifting Operations and Lifting Equipment Regulations SI 1998/ 2307 (LOLER) and various classification prerequisites. All operators perform rocking tests and grease analysis of slew rings as a matter of routine. All operations involving cranes and rigging are guided in accordance to ASME B30 safety standard for cableways, cranes, hoists, jacks and slings.

Scaffolding

The purpose of scaffold erection is to provide access for rigs, jack-up legs, pipework construction or for fabrication of super structures /dynamic heavy lift. More specifically, scaffolds such as hanging scaffolds, load bearing birdcage, tower façade are erected for special services were cranes are not viable or the boom length may be insufficient for a particular job task. Dorman Long provides Advanced Construction Industry Scaffolders Record (CISR) scaffolding crew. These are Offshore Petroleum Industry Training Organization (OPITO) approved rigging personnel with certified rope lighting sling standard to DNV 2.7-1 or BS EN131414-1:2003
