Introduction

In an effort to reduce accidents associated with manriding operations, in January 2001 the STEPCHANGE IN SAFETY Manriding Safety Workgroup was formed. The objective was to publishcurrent best practice information for manriding in derricks, masts and moonpools in onedocument.

This guide is a cross industry product and a list of participating companies is given at the endof this guide, it also contains many of the posters issued throughout the campaign. Many ofthe participating companies are international, and although this Best Practice Guide is intendedfor use in the UKCS, the group hope that it will be used world wide.

It should always be remembered that manriding operations must be considered as thelast option, non routine and subject to stringent planning and controls.

Ultimately I would like all manriding operations either to be engineered out of the job, oralternatives used. Some examples of how this can be done can be seen in the results of the2001 awards competition Top 10 Replacements for Manriding, shown opposite.

In February 2001 this poster was used to request input from the Industry.

5

One of the Lord Cullen's recommendations following the Piper Alpha Disaster was that, as an industrywe must be able to demonstrate the competence of the workforce.

So what is competence? Competence is the ability to perform a task to a required standard. When a personhas the necessary knowledge, skills and ability to perform a task to the required standard, that person isdeemed to be competent. Training and competence go hand in hand, you cannot have one without theother. A person cannot be deemed to be competent, unless he has been trained and/or assessed againstpre-determined criteria for the task. The person once trained must demonstrate he can consistently performthe task to the required standard.

It is recommended that the following areas are addressed in any manriding competencyprogram :-

Principles, Policies and Procedures Knowledge of Applicable Legislation Task Based Risk Assessment Manriding Rig Specific Procedure Permit To Work Mechanics of Manriding

Checklists and Notices Pre-Operations Checklist Warning Notices

Environmental Assessment Current and Continuing Assessment of Weather Conditions

Pre-Job Planning Reasons and Objectives for Manriding Operation Toolbox Talk Feedback Emergency Rescue Procedures

Equipment Harness Winch Line and Ferrule Winch and Utility Air Supply Other equipment made safe

Safety Devices Correct PPE, including high visibility items Air Winch Safety Features (see page 13, Manriding Equipment) Fall Arrester

Communications Hand signals Radio Signals

Using Tools Safe system for tools aloft

Operations Review Post Operations Checklist Demobilisation Man Riding Log

Manriding Hand SignalsHarmonisation

Following an extensive survey of the Oil and Gas Industry Sector in the UK North Sea in 2001conducted by the STEP Change Manriding Safety Workgroup, the overwhelming view of thesector was the desire to move towards a common system of hand signals for manridingoperations. There were 2 systems in common use at the time with both the up and down signalsin opposition to each other.

Due to this difference in signals, the potential for accidents was extremely high, especially withthe high numbers of personnel moving from one company to another and from installationto installation. A change to one system of handsignals made common sense.

In the replies to the survey the workgroup found good reasons for both sets of hand signals,however the popular agreement was that the manriding hand signals should where possiblereflect other commonly used signals in the offshore environment, particularly crane signals.There was also a majority preference to move to the system of signals depicted in the posteropposite.

As we know, good communication is the key to success in everything that we undertake, andthe bottom line is that all persons involved in a manriding operation must understand the handsignals to be used, prior to the commencement of a manriding task.

The utilisation of the hand signals opposite, will help eradicate confusion and reduce thefrequency of incidents.

REMEMBER, WINCH OPERATOR TO KEEP MANRIDER IN VIEW AT ALL TIMES

8This poster was issued to harmonise handsignals used.

This poster was issued early on in the project to outline the important areasto consider when Manriding.

Manriding CompetenceTask List

P

All persons involved in manriding operations must demonstrate a baseline of competency priorto becoming involved in manriding operations.

This Manriding Competence Task List is to support and not replace any planned or existingtraining you have on your installation, and is a checklist of minimum standard.

It is also important that a record of the type of manriding equipment you have been deemedcompetent to use is retained on company record. Also keep a copy of this checklist for yourcompetency profile.

If the manriding equipment on your installation changes or you move to a different installationthen the competence task list will need to be re-visited.

After you have consistently performed the competencies below a responsible competentsupervisor who has witnessed you completing the tasks will sign the record of competency.

REMEMBER, IF THERE IS AN ALTERNATIVE, FEASIBLE METHOD OF CARRYINGOUT THE TASK, DO IT !

PRE - MANRIDING CHECKLIST Manriding Task: Date:

All persons involved in the manriding operation are to be involved in the completion of the checklist YES NOHave the reasons for manriding and job objectives been adequately explained to you ? Have you reviewed the Risk Assessment and the Rig Specific Procedure for Manriding ?Are the current environmental conditions suitable for performing Manriding Activities ? Have you attended a pre job meeting with all the people involved ?Have you reviewed the emergency escape and rescue plan and examined the associated equipment ?Is a Permit to Work required, have all control measures been implemented ?Have all other planned activities that may interfere with manriding been stopped ?Have 'DO NOT USE' warning signs should be placed on the drillers brake/derrick ladder/otherwinches/other interfering machinery ? (machinery isolated ?)If 'over the side' working is possible has a standby boat been notified ?Hand Signals - Have the RAISE, STOP and LOWER hand signal been agreed with the crew involved ?Has the winch operator agreed the principle of 'NO SIGNAL NO MOVEMENT' ?If using Radios - Have the RAISE, STOP and LOWER signals been agreed with the crew involved ? If using Radios, have they been checked and tested, using a dedicated channel ?Is the harness, carbina/shackle and winch line ferrule certification in date, clean and all in goodcondition ?Has the harness been adjusted properly, and is the manrider wearing a helmet chin strap ?Is the winch line connected directly to the harness ? (No swivels or hooks)Is the winch marked 'MANRIDING WINCH' and is the winch certification in date ?Is the winch cable in good condition, and spooled correctly ? (min 6 turns on drum,)Where possible, have mast obstacles been tied back and checked ?Are the manual and automatic brakes operating correctly ?Does the control lever operate correctly, is it clearly marked, and does it return to neutralautomatically ?Has the emergency stop facility been tested ?If fitted, has the load limiter been overload tested ?If a fall arrestor (inertia block) is to be used, has it been tested before use, and does it have aseparate means of connection to the harness? (safety hooks are not permitted)Has the approach route been checked, will the operator do a check each time he lowers themanrider ?Has the winch operator agreed that he will not leave the winch while the person is manriding ?Are the hand tools of sufficient size for easy handling ? Are the hand tools tied off to the harness/manrider securely ?Have the manrider's pockets been emptied of loose articles (especially money and other small metalobjects)Has an operations review been held ? (Make comments below)Has the equipment been properly demobilised ? (cleaned, inspected, records updated, correctly stored)Has the manriding register been completed ?

Manriding Equipment

13

If there is no alternative to manriding the following equipment should be used with the listedsafety features.

1 WinchLimited maximum pull, (counter balanced system for use on floating installations)Independent secondary braking systemSlack line shut-off mechanismControl lever returns to neutral (STOP), push lever away = pay out (LOWER),Pull lever = heave in (RAISE).Crown Block Sheave designed for manriding. (Fall protection for whole assembly including sheave)Emergency stop facility (unobstructed)Wire rope termination to comply with current standardsSpooling deviceDrum guardUpper and lower travel limit switchesEmergency lowering facility

2. HarnessFull body type'D' rings for carrying hand toolsRescue or fall arrest lanyard (see 5)Safe system for tools aloft (lanyards etc)

3. PPEIn addition to normal rig PPE, wear a high visibility jacketor manrider armbands.Always fit and use a chin strap on the hard hat.

4. Connecting DevicesMust incorporate a simple locking device which canonly be manually activatedOverhoist protection placed 4 ft above manrider,eg oversized end link

5. Secondary Fall Arrest EquipmentUse an additional safety device (where practical) attached to a safepart of the harness.(fall arrestor, inertia reel, line locker, pennant line)

6. RadiosEnsure there is a system to maintain and issue radios.

When radios are appropriate for the job, establish a Radio Communication Voice Procedure :-Use a dedicated channel where possible.Always speak slowly and clearly, never talk over or interrupt.At the end of each communication say "over", only then is it safe for someone else to speak.Never use the radio to have a chat with your mates.Assign everyone a call sign and use it (winch control, manrider, driller etc)Use continuous direction commands ie, (up, up, up, up, up, / down, down, down, down/ stop, stop, stop)Remember NO COMMAND = STOP THE AIR WINCHIf there are long periods of silence, call for a radio check with everyone involved.If your radio stops working, contact the team by another means ASAP and get it replaced. If you are the manrider useyour hand signals to return to the rig floor.

Emergency Plans& Equipment

Before any manriding operation can commence, a rescue plan must be considered as part ofthe pre-task risk assessment and all relevant equipment must be readily available.

It must be recognized that a rescue operation can introduce its own hazards, therefore the planning and executionof this operation requires particular care, consideration and further risk assessment before commencing.

The maximum recommended suspension time for any individual, in harness, is twenty minutes.Any longer then this and the individual may start to lose circulation in the limbs held by theharness, this can result in discomfort and at worse, loss of consciousness. However, considerationmust be given to repairing malfunctioning equipment before attempting a rescue if the equipmentcan be repaired safely if the manrider is not in any immediate danger ie, if the air supply to thewinch fails but can be reinstated within a short timeframe. He may then be brought to safetyonce the equipment is repaired.

Equipment that may be an integral part of a rig's Rescue Plan:

1. Harness - Full body type fitted with a D ring suitable for rescue purposes.2. Alternative nitrogen or air supply to winch3. Secondary winch4. Rescue basket (for use with alternative winch)5. Cherry picker6. Fully charged radios7. Emergency manual lowering device on main manriding winch8. Emergency Descent/Ascent device (personnel must be trained in use)

The use of emergency ascent/descent devices, such as Spanset and Gotcha, should only beused if no other alternative can be found. Only trained personnel should operate the devices.

As with any manriding task, during a rescue operation it is essential that, in the eventcircumstances change, full reassessment of conditions is conducted to ensure thecontinued safety of everyone involved.

14

Manriding Register

Key components of the register:-

TASK Identify the actual task for which manriding is perceived to be required.

ALTERNATIVE METHOD Members of the team consider and detail alternative methods that could be

utilised in place of the man-riding operation.

ALTERNATIVE METHOD USED AND JUSTIFICATION Indicate if the alternative method was used (yes or no) and detail the reasoning

for non application or application of the alternative.

See example Manriding Register on page 16

(The Example Manriding Register can be downloaded as a spreadsheetfrom www.stepchangeinsafety.net)

15

To eliminate manriding as much as possible, a Man Riding Register can be used to documentwhen alternatives to manriding have been successful. The purpose of the register is to facilitatea simple evaluation of the need to manride and to log potential alternatives. The register canalso be used as a lateral learning tool for other crews/rigs in a company.
