13.9.8
Loading arm manoeuvring controls including QCDC activation Slow/fast manoeuvring selection Hydraulic pump on/off Loading arm selector switch
an emergency release coupling two ball valves, one positioned immediately upstream and one positioned immediately downstream of the emergency release coupling, closing prior to emergency release.
The emergency release system (ERS) control conditions will be as follows: 1)
Excess Angle alarm An audio-visual alarm (ESD-1 condition (refer to Section 13.11.7)) shall at all times be initiated when the loading arm crosses its working range limit as specified in the data sheet or working range diagram. This should occur at the jetty control panel and also be transmitted as an alarm to the Central Control Room.
2)
Automatic Emergency Release The ERS of each individual arm shall at all times be automatically activated when the arm travels beyond its working range limit (ESD-2 condition (refer to Section 13.11.7)) reduced with a safety margin as specified in the data sheet or working range diagram. This releasing signal shall be incorporated also with jetty shutdown signal provided by others.
3)
Manual Mechanical Emergency Release A manual emergency release for each individual arm shall be possible in case of vital power failure by pulling/pushing the emergency knob or lever. The emergency release knob or lever shall be protected against accidental operation (e.g. by safety pin or cover). After pulling of the emergency knob or lever the hydraulic valve shall be detained in that position so that operator does not need to hold knob until the arm has been disconnected.
13.9.9
ERS operation 1)
The solenoid operated hydraulic directional valves for the operation of ball valves and emergency coupling shall be leak proof.
2)
When arm is parked and locked by its storm lock the hydraulic power to this arm shall be blocked and the ERS system shall be de-activated.
3)
At the parking lock a proximity switch shall be incorporated which shall cancel any signal which will activate the ERS for that particular arm when the arm is properly parked.
4)
In case of emergency release the loading arms will be automatically retracted towards their stored position. The full retraction must be drived by computed movements using PMS, to achieve a complete and clean disconnection and retraction whatever initial position of arms connected to ship is (inside working range). No risk of clash with the overall structure of the ship and/or the jetty, including fendering installation, must exist.
5)
The outboard arm's hydraulic power system shall automatically retract the outboard arm hydraulically inside berthing line during the release of the emergency coupling. The motion of the outboard arm must be referred to the riser independently from the inboard arm motion. In emergency disconnection condition the outboard arm angle position is relative to the riser axis.
6)
The inboard arm hydraulic power system shall include an adjustable flow regulator or other damping device in order to limit the return velocity of the inboard arm under
Page 57 released conditions. The inboard arm shall be controlled in such a way that the complete arm will be returned towards shore berthing line. 7)
During the release of the emergency coupling the hydraulic power system shall automatically block the slewing movement of the arm due to the wind load and consequently prevent collision of the disconnected arms.
8)
An override in the hydraulic systems for outboard arm and slewing drives shall be provided to limit possible excessive forces exerted by the ship on the release coupling during release.
9)
The system shall be so designed as to allow provision to avoid the accidental operation of the emergency release system unless the loading arm is connected to a tanker manifold flange.

2)
ESD-2: A second stage overreach audible and visual alarm shall be actuated prior to the loading arm reaching its design envelope boundary and shall initiate the closure of the ERS ball valves and stopping the ship Unloading Pumps, (if not already actioned during ESD-1) using an independent circuit to the first stage, followed by emergency release coupling actuation.
The objective is to start closing the valves slowly during ESD-1 to avoid surges in the pipe line. If however the valves are not completely shut by the time ESD-2 occurs which indicates that the arm has moved further outside its operating envelope, then the actuator shall take over and shut the valves faster, to ensure effective valve closure before the ERS coupling is released. 13.11.8
Terminals shall be provided to receive signals from the ship carry-on box to activate the ERS.

Design considerations: Items
The design of each arm to be such that there is no clash with piping or adjacent structures The arms will be purged with nitrogen. Vendor to provide a valved connection with purge lines and flexible hoses to a coupling at the shore end of the loading arm. Articulated joints to be sealed to prevent icing in joints. Nitrogen purge connections to be provided on each joint. Each loading arm to be equipped with a po wered emergency release coupling (PERC) which isolates the ship from the loading arm using two ball valves and breaks the connection between ship and shore automatically if the loading arm is over extended. Arms are to be equipped with two stage limit switch trip system with visible and audible alarms to prevent over extension of the arm. Connections (for LNG and NG) Jetty side 20” flanged ANSI B16.5 300# RF Ship side to be suitable for connection to LNG tanker manifolds with various flange types (ANSI, BS or DIN). The size range may be accommodated by the use of spool pieces. All unloading arms are to be designed to permit reverse flow. This will allow LNG transfer to a ship at reduced flow rate via the liquid arms and vapour from a ship to pass to the terminal vapour recovery system via the vapour arm. The design of loading arms shall be suitable in all aspects to accommodate the 33% and 20% short term emergency over-pressure allowed by ANSI B31.3. Hazardous area classification for the loading arms shall be zone 1. In the event of a power or hydraulic failure, the coupling shall remain securely fastened to the tanker manifold. Accumulators or other back up devices shall be provided to allo w for manual coupling release in this event. “Carry on Box” or equivalent ship/shore link between ship ESD and terminal ESD systems to be provided.

Notes: Items
Vendor shall supply pressure drop versus flow rate data for arms. Operating envelope to be developed based on LNG tanker dimensions and finalised jetty layout. LNG unloading arms to be compatible, so that a common electro-hydraulic power system can be utilized. The emergency release system (ERS), which is activated on emergency s eparation of the ship from the jetty, to be interlinked with the ERS of the LNG unloading arms to ensure release of all arms simultaneously. The shutdown system of all the arms to be compatible The vendor shall demonstrate by fault tree analysis that the fractional dead time of the overall loading arm shutdown system shall not exceed 0.001. For painting and protective coating requirement, refer to attached Purchaser’s specification.

use of inorganic zinc silicate (B1) to surfaces having an operating temperature in excess of 150 C. (C10)
For C10 where it is required to apply a priming and finishing coat system identical to adjacent surfaces in way of bolted areas etc., use the specified inorganic zinc silicate primer (B1) where it has been possible to blast clean the surface or where the operating o
o
temperature is in excess of 150 C, and use aluminium filled modified epoxy (B6) as a primer for surfaces up to 150 C where it has only been possible to power tool clean the surface.

Galvanised high strength bolting shall be to ASTM A325 Type 1. The rods, clevises, clamps used in pipe support and guide assemblies, excluding springs and other standard manufactured items, shall be to the above mentioned standards. The galvanised items are unpainted, unless specified for safety markings on other considerations.

DESIGN 2.1
2.2
Shell and Head Seam Layout 2.1.1
Longitudinal seams in adjacent shell rings shall be offset by a minimum of 4 time the plate thickness or 150mm whichever is greater.
2.1.2
Seams in horizontal vessels shall not be located coincident with or or across saddle supports.
2.1.3
Plate layout shall be arranged so that to the maximum extent possible, longitudinal and circumferential weld seams clear all nozzles, man ways, and their reinforcing pads by 50mm minimum measured weld edge to weld edge.
2.1.4
When nozzles must penetrate, or when nozzles reinforcing pad must cover weld seams, the seam shall be ground flush and 100% radiographically examined before welding the nozzle. The seam shall be radiography for a distance of 150mm beyond the nozzle or the outside diameter of the reinforcing pad, whichever is greater.
