No anchor movement is allowed inside the oil fields without a work permit. Work equipment is not to anchor inside the perimeter of the oil field, except at safe anchoring areas or at buoyed work sites. No dropping of anchors is allowed within an oil field except as directed by a Rigmove Master and for this reason, three assisting vessels all of which must have anchor handling capability, must be in attendance for all moves, two to tow and one to set and recover anchors. The supply and backup vessels are in no way permitted to be tied into any platform. Offshore Unit’s are not permitted to anchor at work sites until a Move In and Set-Up Work Permit has been issued by the responsible Producing representative. Offshore Unit’s may anchor within the confines of a safe anchoring area without a Work Permit. 8.2. Anchors for work Offshore Unit’s are not to be set or picked up at a work site until the responsible Producing representative has issued a Work Permit covering the action. 8.3. Where an anchor cable is to cross a sub sea pipeline, the anchor must be at least 600 feet across the line if it is depressurized and 1,200 feet if the line is "hot". 8.3.1. If any anchor wire lying across a sub sea line is in contact with or likely to be in contact with that line, it must be supported at the crossing by parachute / buoyancy / DP buoys to avoid damage. Damage prevention buoy locations will be determined at the Rig/Barge Move Meeting and after setting will be marked with a distinctive buoy to facilitate inspection. 8.3.2. Where an anchor is laid up to a pipeline but not across, it should be a minimum of 300 feet from the line. 8.3.3. The requirement for anchor wires run across pipeline/cable will be determined at the "Work Review and Planning Meeting". Producing Department will have a representative on duty at the job site to issue the Work Permit. Similar to the Rigmove Master this representative will have to have single accommodation aboard the marine craft on certain jobs. 8.4. Prior to setting anchors, the anchor location will be buoyed and dive checked if required.

SAUDI ARABIAN OIL COMPANY (Saudi Aramco) Page 11 of 36 OPERATIONS INSTRUCTION MANUAL ISSUING ORG.: NORTHERN AREA OIL OPERATIONS SUBJECT: WORK AROUND OFFSHORE PRODUCING FACILITIES: INSTRUCTION NO. 1.519 Issued: 10-07-2008 Replaces: 08/24/2003 Complete Revision Next Review: 10-07-2013 * Change ** New Addition 8.4.1. If anchor handling vessel is fitted with survey equipment, anchors may be set and dive checked afterwards. Survey vessel checks may also be used to confirm locations and for drag watch on buoys. 8.4.2. No anchors shall be moved across existing pipeline while anchors are suspended from anchor handling tugs or barges. All anchors must be on deck, with a safety strap/wire installed if they are to be moved across a pipeline. 8.4.3. No anchor may be moved such that the anchor cable sweeps along the pipeline. 8.5. When the agreed anchor position is deemed "critical" due to proximity to existing surface or underwater facilities or due to potential interference with anchor patterns of other Offshore Unit’s working in the same area, a diver will be required to "spot" anchors as they are set and ensure they are clear. Divers will be required to "spot" anchors as determined by the Rig Move Master. 8.6. All anchors will be fitted with wire pendants of adequate length for the water depth with suitcase style buoys. The wire pendant must be secured to the "crown" of the anchor. 8.7. No Work Permit is to be issued until all required buoys are installed and all necessary lines inside the area of operation required to be shut in have been depressurized. Deviations from this procedure, if required by operational contingencies, will require approval from the Superintendent or higher Producing Management. 8.8. After work has started, no anchors are to be moved until the responsible Producing representative has issued a Work Permit covering the move. 8.9. When entering, leaving or moving within an oil field, all anchors must be hove in and secured by a safety strap in the case of anchors connected by wires. Where anchors are connected by normal chain with purpose built gypsies, the compressor or Guillotine arrangements must be operational and in use. 8.10. No vessels other than those approved by the Producing Department shall berth at existing Offshore Platforms. Vessels working at existing platforms must moor in a safe and seaman-like manner to avoid damage to the platform and themselves. "No work vessel shall remain alongside existing platforms during the hours of darkness, but must proceed to a safe anchorage for the night". The provisions of Sections 7.1 and 7.2 above apply to the anchoring of such vessels. "But this prohibition may be waived" for contractor's vessels at the discretion of the Operations Superintendent. 8.11. Where crossing of a pipeline or setting of anchors may be potentially hazardous, or present difficult working conditions, offshore units may "Soft Line" to the legs of a conventional pile driven jacket. A "Soft Line" is a synthetic or natural fiber rope which is secured by a shackle to a conventional anchor/mooring wire to form a "bight", which is passed around the leg of the jacket. (Producing consent).

(b) Certificates of test, or calculations showing the safe working load and breaking strain of the rope. * (c) The Maximum amount of stress / strain to be used. * Formal consent to "soft line" should be sought at the work planning meeting, and final approval will be given by the Operations Superintendent, at the Rig Move Meeting. Soft Lines are to be regarded as a Last Resort, permission for the use of soft lines will not be granted as a rule. Each case will be looked at separately and the age / condition of the platform will be taken into account. Where soft line use is approved, it must be removed as soon as possible and definitely before the departure of the barge. ** 9. ANCHORING AT RIG/JACK-UP BARGE LOCATION FOR SUPPLY PURPOSES 9.1 The vessel must obtain prior permission from the Rig Foreman before approaching any Offshore Rig/Barge. Rig foreman or his delegate must give the supply boat clear instructions on the safe anchoring location as indicated in the rig move meeting. 9.2 No anchoring is allowed at any location where there is a subsea pipeline or cable within 400 meters of the rig. In congested areas this may require the use of DP Vessels only to supply the Rig. 9.3 When a rig is on location, all underwater pipelines and/or cables in way of supply boat anchors, loading or discharging at the rig, must be continuously buoyed as indicated in the Rig Move Meeting Minutes. In congested work sites a specific anchor location buoy (Spar Buoy) shall be deployed. It is the responsibility of Rig Foreman to ensure full compliance with the provisions of safe anchoring (i.e. spar buoy and continuous subsea pipelines/cables buoying). 9.3 Where there are any pipelines or power cables in the vicinity of any rig, a notice will be placed on the rig in the control room by the Rig Move Master relocating the rig. The notice shall be also passed to all vessels via the Marine AHTSS foremen at Tanajib to be kept on the bridge, instructing all vessels where anchoring is prohibited and where the safe anchoring position is located. The Drilling Foreman, as the Saudi Aramco Representative on board the rig, will be also given a copy of the notice and will observe its enforcement.

Masters must consider the buoy to mark the most extreme distance for anchoring from the Rig/Barge, and should anchor between the Spar Buoy and the side of the Rig/Barge, and NEVER on the far side of the buoy. 9.7 The Spar Buoy will be deployed by a survey vessel (e.g. Karan 8) to ensure the correct positioning of buoy. The vessel used to position the Spar Buoy will enter the exact position of the Spar Buoy in the Deck Log-book. A survey Work Order must be raised by the Drilling Foreman for the positioning of the Spar Buoy. 9.8 The Master of the supply vessel will ascertain whether the Spar Buoy is in the correct/agreed position. If the Master has any doubts about the position of the Spar Buoy, he shall immediately report this to the Rig Foreman and the Rig Move Office. 9.9 The Master of the supply vessel shall use all available navigation aids (e.g., Radar Range & Bearing or DGPS) to ascertain anchor drop position.
