Clasification Society Rules and Regulations - Rules and Regulations for the Classification of Offshore Units, January 2016 - Part 3 FUNCTIONAL UNIT TYPES AND SPECIAL FEATURES - Chapter 7 Drilling Plant Facility - Section 10 Risks to personnel from dropped objects
Section 10 Risks to personnel from dropped objects
10.1 Goal
10.1.1 The requirements of this Section are to ensure that risks to personnel from dropped objects, hereinafter referred to as DROPS, are continuously addressed, in so far as they affect the objectives of classification.
10.2 Class notation
10.2.1 Where the requirements of this Section are met to the satisfaction of LR, units will be eligible to be assigned the DROPS class notation. This notation will be retained as long as the preventive measures to protect personnel from hazards from dropped objects are found, upon examination at the prescribed surveys, to be maintained to the satisfaction of LR.
10.3 Scope
10.3.1 Each unit is required to have a DROPS management system in place and be relevant to the design and specifics of the unit.
10.3.2 The Builder or Owner will create a general arrangement drawing of critical DROPS areas which will be clearly displayed in general information areas throughout the unit and accommodation.
- Green Zone:
Where the layout and activities of the area present little likelihood of personnel being exposed to potential dropped objects under normal circumstances.
- Yellow Zone:
Where the layout and activities of the area present some risk of personnel being exposed to potential dropped objects under normal circumstances.
- Red Zone:
Where the layout and activities of the area present significant risk of personnel being exposed to potential dropped objects under normal circumstances.
10.3.4 Zones are to be clearly displayed at all access points to the respective areas. All signs are to be pictorial to eliminate potential issues with different languages. Refer to BS EN IEC 62079:2001 Section 4.7.3.2 for further information.
10.3.5 All third party equipment, permanent or temporary, is to undergo a design risk assessment before installation. Records and methods of inspecting the third party equipment are to be maintained and available for LR review.
10.3.6 Suitable equipment and hand tools for working at height are to be provided. Details and records of inspection of such tools and equipment are to be maintained and available for LR review.
10.3.7 When the use of DROPS shelters are incorporated into the safety management system, full structural and installation details of the shelters, including the intended level of safety, are to be presented for LR review.
10.3.8 The preventive maintenance systems of the unit are to indicate where specialised work at height tooling is required for routine maintenance.
10.3.9 An inventory of permanent fixed equipment is to be created and maintained by the unit; the inventory is to include photographs and a description of each item. The photographs are to be taken from a distance and also from close up to avoid confusion with identification. Each individual item of equipment is to be identified by permanent marking or by the use of suitably attached durable labels.
10.3.10 An inventory of temporarily installed equipment is to be created and maintained by the unit. This will incorporate scheduled routine inspections to verify that no modifications, changes or damage to the equipment has occurred since the initial inspection on installation, or previous scheduled inspection.
10.3.11 A program of scheduled surveys and inspection will be created; methods and records of inspection and any remedial actions are to be maintained and available for LR review.
10.3.12 A record of failed items, with reason for failure, is to be maintained and is to be available for review by LR.
