Rules IV Industrial Services Part 7 Offshore Substations Chapter 3 General Safety Section 4 Live-Saving Appliances B Survival Crafts B.1 Manned installations B.1.1 On each manned installation at least one lifeboat complying with the requirements of the LSA Code shall be provided. Depending on outcome of evacuation assessment more than one may be required based on actual size of the installation, overall number of persons onboard and general platform arrangement. The lifeboat capacity has to be sufficient to accommodate the total number of persons on board. B.1.2 Special consideration is to be given to retrieval of persons from sea. For this purpose a lifeboat with MOB capabilities or a fast rescue boat shall be provided. A lifeboat may be accepted as a rescue boat, provided that it and its launching and recovery arrangements also comply with the requirements for a rescue boat. B.2 Manned and unmanned installations: B.2.1 On each installation a launchable liferaft or liferafts, complying with the requirements of the LSA Code shall be provided. The liferafts shall be approved to the actual operating height, capable of being launched on either side of the unit. The total capacity available on each side shall be sufficient to accommodate the total number of persons on board, unless an analysis is presented and approved by GL to show that a smaller capacity can be accepted. B.3 Unmanned installations B.3.1 Special consideration is to be given to retrieval of persons from sea. This can be achieved • by installation of rescue boat on the platform; or • by having a vessel with MOB capabilities in the immediate vicinity of the installation when people are on board. B.4 Survival craft launching stations B.4.1 Survival craft launching stations should be in such positions as to ensure safe launching having particular regard to clearance from steeply overhanging portions of the platform. As far as possible, launching stations should be located so that survival craft can be launched down a straight side of the platform, except for: • survival craft specially designed for free-fall launching; and • survival craft mounted on structures intended to provide clearance from lower structures. B.4.2 Operating instructions and illustrations should be provided on or in the vicinity of survival craft and their launching controls and should: • illustrate the purpose of controls and the procedures for operating the appliance and give relevant instructions or warnings; • be easily seen under emergency lighting conditions; and • use symbols in accordance with the recommendations of SOLAS, MODU Code, National Regulations, etc. as far as applicable B.5 Stowage of survival craft B.5.1 Each survival craft should be stowed: • so that neither the survival craft nor its stowage arrangements will interfere with the operation of any other survival craft or rescue boat at any other launching station; • as near the water surface as is safe and practicable; • in a state of continuous readiness so that two crew members can carry out preparations for embarkation and launching in less than 5 min; Edition 2013 Germanischer Lloyd Page 4–2
Rules IV Industrial Services Part 7 Offshore Substations Chapter 3 General Safety Section 4 Live-Saving Appliances • fully equipped as required by the LSA Code; however, in the case of platforms installed in areas such that, in the opinion of GL, certain items of equipment are unnecessary, GL may allow these items to be dispensed with; • as far as practicable, in a secure and sheltered position and protected from damage by fire, explosion ore crane operation. B.5.2 Lifeboats should be stowed attached to launching appliances. B.5.3 Liferafts should be so stowed as to permit manual release of one raft or container at a time from their securing arrangements. B.5.4 Davit-launched liferafts should be stowed within reach of the lifting hooks. B.6 Survival craft launching and recovery arrangements B.6.1 Launching appliances complying with the requirements of the LSA Code should be provided for all lifeboats and davit-launched liferafts. B.6.2 the unit. Only one type of release mechanism should be used for similar survival craft carried on board B.6.3 Preparation and handling of survival craft at any one launching station should not interfere with the prompt preparation and handling of any other survival craft or rescue boat at any other station. B.6.4 During preparation and launching, the survival craft, its launching appliance and the area of water into which it is to be launched should be adequately illuminated by emergency lighting. B.6.5 Prevent any discharge of fluids on to survival craft during abandonment. B.6.6 All lifeboats required for abandonment by the total number of persons permitted on board, should be capable of being launched with their full complement of persons and equipment within 10 min from the time the signal to abandon the unit is given. B.6.7 Manual brakes should be so arranged that the brake is always applied unless the operator, or a mechanism activated by the operator, holds the brake control in the “off” position. B.6.8 Consideration should be given to the location and orientation of the survival craft with reference to platform design and environmental orientation, such that clearance of the unit is achieved in an efficient and safe manner having due regard to the capabilities of the survival craft. C Rescue Boats C.1 Rescue boats should be stowed: • in a state of continuous readiness for launching in not more than 5 min; • if of an inflatable type, in a fully inflated condition at all times; • in a position suitable for launching and recovery; • so that neither the rescue boats nor their stowage arrangements will interfere with the operation of any survival craft at any other launching station; • in compliance with section B.5, if they are also lifeboats. C.2 Launching arrangements should comply with B.6 C.3 Rapid recovery of the rescue boat should be possible when loaded with its full complement of persons and equipment. If the rescue boat is also a lifeboat, rapid recovery should be possible when loaded with its lifeboat equipment and the approved rescue boat complement of at least six persons.
